LEGISLATIVE ACTS IN AGRICULTURE AND ENVIRONMENT IN NOVI VINODOLSKI (CROATIA) IN THE 17TH CENTURY pag. 3-11
Ž. BARTULOVIĆ,1 D. HAMAN2This paper presents analysis of urbariums as legal acts that regulate mutual rights and obligations of feudal lords and serfs. Urbariums are usually not unilateral acts of the feudal lord imposing obligations on the serfs, but the term contract is also used originally because the consent of both parties is required, regardless of the fact that the subjects are in a weaker position. Urbariums can be compared with modern acts of labor law, i.e. collective agreements. Urbariums are usually researched exclusively from the legal aspect, leaving data on agriculture and animal husbandry, as well as the use and protection of uncultivated land (pastures and forests) usually neglected. As such data can be investigated on the basis of mandatory payments of serfs to feudal lords and their work obligations, this paper aims to elaborate different types of income and expenditure accounts arising in 1593 in Vinodol, as compiled by the manager Marko Oršić, and determined by the Urbarium of Novi from 1606 and 1653. From the data on the restrictions on the use of uncultivated land, it can be determined that the inhabitants of that time carefully guarded it against excessive use or destruction, which could be defined today as an example of sustainable development.

DownloadASSESSMENT OF MINERAL COMPOUNDS IN DIFFERENT POPULATIONS OF THYME (THYMUS L.)* pag. 12-19
Rodica BEICU, Adina BERBECEA, Sorina POPESCU, Georgeta POP, Giancarla VELICEVICI, Ana Maria IMBREA, Alina NEACŞU, M. BALINT, Ilinca-Merima IMBREAThe mineral profile of thyme, a species so often used as a medicinal plant or spice, represents a permanent and significant research topic for the fields of agronomy, chemotaxonomy, biochemistry. Previous studies have indicated a significant number of organic substances with high antimicrobial potential not only in cultivated but also in spontaneous populations of thyme, revealing the phytobiological value of these species. We are in a permanent search for new resources from the wild flora, necessary either for direct use or introduction into culture. In this context, the study evaluates the mineral profile related to 17 spontaneous populations of thyme identified in the Banat area, compared to a cultivated population, investigating the quality of the biological material analyzed. The content of total mineral substances (ash) in the analyzed populations varied between 1.19% in the population of Th. pannonicus ssp. auctus from the Silagiu area and 10.85% in the cultivated thyme (Th. vulgaris), observing the existence of individual variations depending on the species, but also depending on the harvesting area. The characteristics of the biotope are defining and influence the mineral profile of the thyme populations in natural areas. Among the mineral elements analyzed in the present work, those related to the analysis of the macroelement content are presented. The amount of calcium accumulated in the dry vegetable mass can represent a relevant indication as a species character, if it will be confirmed by other specialized studies.

DownloadNATURE-BASED SOLUTIONS - A BRIEF OVERVIEW OF THE PERSPECTIVE OF THE CITIES IN THE LIGHT OF CLIMATE CHANGE pag. 20-32
Iudit BERE – SEMEREDI, Roxana SIRBU, Anca DRĂGHICINature-Based Solutions (NBS) are playing an increasingly important role in helping cities to mitigate the effects of climate change and significantly increase their resilience through the promotion of green and blue infrastructure. This study analyzed 38 articles on nature-based solutions with a direct focus on climate change mitigation and adaptation in the urban environment, targeting European cities. The aim of the review was to systematically analyses the nature-based solutions for adapting to and mitigating the effects of climate change in the selected articles, revealing the diversity of issues explored, the approaches and solutions proposed in different concrete applications, and the challenges that currently exist in reconciling cities and nature. The results of the analysis also show that, despite the large number of studies carried out at the urban level, the practical approaches of the NBS focus on one city or groups of cities that generally face similar challenges: urban heat islands, stormwater management, green areas, tested and implemented green infrastructure (GI) solutions, blue-green infrastructure. We found that ecosystem-based adaptation in the urban context is fragmented due to the different urban challenges: mainly flooding or heat and the corresponding risk reduction solutions: wetlands, green spaces, trees, parks. A key finding of the articles analyzed the involvement of stakeholders in urban and NBS planning. A more in-depth analysis and systematization of good practices at the level of urban areas can be achieved by analyzing the entire literature in the field of NBS and climate change mitigation and adaptation, categorized according to different themes, through a multidisciplinary effort.

DownloadFACTS REGARDING STIGMINA CARPOPHILA IN PRUNUS SP. ORCHARDS FROM WESTERN PART OF ROMANIA pag. 33-38
A. BORCEAN1 Casiana MIHUȚ1 A. OKROS1During the last five years, one of the targets of our research work from the area of South-Western part of Romania was to determine the most important diseases sources for maintaining their infectious pressure the diseases of plum trees from a very favorable area as there are the western part of Romania. Also, it is an attempt to see the dynamics of those pathogens. It is our duty to show from the very beginning that this paper contain data from last five years of research and this is the reason why data statistic interpretation could suffer dramatic changes in the near future, after we bring more observations data for statistic analyze. On the plum orchards, Stigmina carpophila is one of the pathogens which take it’s share from the leafs of plum trees and so it take a part of the plum crop. Never the less the pathogen produce a premature aging of the trees by reducing each ear the plum trees vigor. As an active measure to prevent this pathogen to produce damage to the trees and plum harvest it is necessary to apply some treatments after a premade plan of trees protection measure. But all these measures bring a higher cost to the harvest and also some pollution by using some fungicides. To reduce the number of treatments it is sometimes useful to know the infetios preasure of the pathogens which are the target of the phytosanitary plan of actions. Results point out that the best rain distribution and temepratures for fungus Stigmina carpophila were in those from 2020.

A. BORCEAN1, Ana Maria IMBREA1On the last two years, one of the targets of our research work from the area of Nera river basin was to determine the diseases of plantains (Plantago sp.) species from Nera river basin. Also, it is an attempt to see the dynamics of those pathogens. It is our duty to show from the very beginning that this paper contain data of just two years of research and this is the reason why data statistic interpretation could suffer dramatic changes in the near future, after we bring more observations data for statistic analyze. Regarding to the work method, all observation data were collected during vegetation period of years 2017 and 2022. In this paper there are presented only averages of data collected during the time period mentioned previously. Our observations consist from three separate operations: first operation was to determine the areas with representative populations of Plantago sp., second to determine the density of those populations and third operation was to see if those plants are affected of some pathogens and forth operation was to evaluate the attack parameters of each pathogen. The novelty is relatively high because this work provides important data for both agricultural practices especially for breeding process and also for local environment protection authorities. Taking in consideration that Plantago sp. plants are used on a relatively large scale for some pharmaceutical and cosmetic industry, it is important to know the infection pressure of the plants pathogens from natural environment. From this point of view, we appreciate that the plants from wild flora are considered to be a consistent source for diseases resistance genes in the plant breeding process. Limits of the research are that data from the research are just from two years and greatly influenced by local climatic and soil factors. Results point out the small variation of attack degree between different populations and between the years of the observations time period

DownloadMICROBIAL BIOINSECTICIDES AND THEIR EFFECTIVENESS IN CORN PEST CONTROL pag. 47-53
Alina Maria COSTEA, Ioana GROZEAMicrobial biopesticides are considered natural elements of biological nature often used to control pests in various agroecosystems. In the present work, we proposed to test some biopesticides to see if they are effective in controlling relevant pests in organically grown corn. Among the frequent pests as target organisms, we considered aphids, chrysomelid (leaf) beetles and lepidopteran larvae. It is known that chemical products cannot be applied in an organic system, that's why we focused on 2 biopesticides (B1-Spinosad and B2-Bactospeine) in use and available on the European market. Thus, in 3 repetitions consisting of different doses, we did tests directly in the field using special cages. I made the observations periodically on 3, 5, 7, 9 and 11 days from July-August, during the year 2022, in a corn crop in Arad County (in western Romania). The effectiveness results were interpreted by the survival rate of the larvae and by the mortality rate. It turned out that both B1 as well as B2 are effective in higher doses. The low survival rate of the targeted pests automatically meant a high mortality rate and vice versa. The efficacy data by the mortality rate were varied depending on the category of pests (64.47%/B1 and 45.56%/B2 for lepidopteran larvae, 40.06%/B1 and 31.12/B2 for chrysomelids and 36.89%/B1 and 45.33% /B2 in aphids). It is clear that where the mortality rate was higher it is the ideal option to be included in the pest control strategy in the maize crop. Of course, a single application is not enough, that's why we recommend a double treatment at an interval of 10-14 days.

Gh. David*, D. Ţărău, Gh. Rogobete, D. Dicu, Saida Feier- DavidThe purpose of these researches and studies carried out in the reference area,consists in obtaining the widest possible fund of knowledge, regarding the characteristics of the natural environment and its macrozonal and microzonal particularities, which will substantiate, both ethnically and scientifically, all the elements that define the structure of the edaphic cover and its favorability, regarding the main cultivated species, in order to develop sustainable management systems of soil and land resources. The researched area refers to a total area of 27601 ha, of which 21376 ha (77.45%) are agricultural lands (10931 ha, respectively 39.61% being arable land) and 4729 ha (17.13%), land with forest vegetation in the Bara-Ghizela area. This is characterized through varied geological and physical-geographical conditions, which conditioned the formation of an edaphic cover,represented by several types of soil such as:Regosols, Alluviosols, Phaeosols, Eutricambosols, Preluvosols, Luvosols, Vertosols, Pelosols, Stagnosols, Gleiosols and Anthrosols. They are distinctly distinguished by their properties and fertility maintenance measures, in relation to the peculiarities of the ecopedological profile of each of the territorial units (TEO/UT). The present work is a very complex one. It provides basic information and methodological elements for the assessment and characterization of soil and land resources, on the basis of which the favorability of soils for pastures, hay, trees and the main cultivated field plants (wheat, barley, corn, soybean, sunflower) has been established. . At the same time, this information can be of real use in agricultural research and practice, as well as for the development of interdisciplinary studies regarding the quality of life.

Doris, FLOARES1, Diana, OBISTIOIU1, Ileana, COCAN2, Anca, HULEA3, Monica, NEGREA2, Liana, BUTTA1, Ersilia, ALEXA2, Isidora, RADULOV1Abstract. In recent years, microbial biofilm resistance has increased, posing significant challenges for the medical community in terms of disease treatment and for the food industry in terms of contamination and loss of shelf life. The purpose of this work is to test the antimicrobial efficacy against Gram-positive bacteria represented by the following reference strains: Streptococcus pyogenes (ATCC 19615), Staphylococcus aureus (ATCC 25923), Listeria monocytogenes (ATCC 19114), Bacillus cereus (ATCC 10876) and Clostridium perfringens (ATCC 13124), as well as the MIC evaluation of three Thuja occidentalis (TO) extracts. In accordance with ISO 20776-1:2019, the evaluation was conducted by measuring the loss of microbial mass using spectrophotometry to determine the optical density (OD). As a result of our research, we can say that to extracts, especially at the first concentration tested cause an inhibiting effect on Gram-positive bacteria. The inhibitory effect on the Gram-positive bacteria is increasing: Cl.perfringens< S. pyogenes< S. aureus < B. cereus < L. monocitogenes. The demonstrated effect of TO2 recommends it as a potential future candidate in natural products with antimicrobial activity. Our findings could allow TO2 blends in many areas, such as products for bacterial dermatological treatments and the food industry, both areas being strongly affected by the increase in antibacterial resistance to standard, commercial antimicrobial products.

Doris, FLOARES1, Diana, OBISTIOIU1, Ileana, COCAN2, Anca, HULEA3, Monica, NEGREA2, Liana, BUTTA1, Ersilia, ALEXA2, Isidora, RADULOV1The spread of multidrug-resistant bacteria has become a significant cause for concern. A real and topical issue is the control and treatment of bacterial diseases, primarily caused by these bacterial mutants resistant to most available antibiotics, which is a real and pressing concern. Numerous studies concentrate on alternative or complementary antimicrobial strategies due to these facts. Antimicrobial compounds derived from natural resources, such as plant extracts, are garnering increasing interest for their activity against various microorganisms in the hope that, unlike antibiotics, they will be effective without inducing resistance. The purpose of this work is to test the antimicrobial efficacy of Thuja occidentalis (TO) extracts against Gram-negative bacteria and fungi represented by the following reference strains: Shigella flexneri (ATCC 12022), Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC 25922), Salmonella typhimurium (ATCC 14028), Haemophilus influenzae type B (ATCC 10211), Candida parapsilopsis (ATCC 22019) and Candida albicans (ATCC 10231), respectively. The evaluation was conducted in accordance with ISO 20776-1:2019 by measuring the loss of microbial mass using spectrophotometry to ascertain the optical density (OD). The best effect was for TO2, and it recommends it as a potential future candidate in natural products with antimicrobial activity. Our findings could allow TO2 usage in several areas, such as products for antimicrobial dermal treatments, the area being strongly affected by the increase in antimicrobial resistance to commercial products. The statistical analysis indicates that TO is highly effective against Gram-negative bacteria and Candida spp., making it a promising candidate for future research.

DownloadTHE EFFECT OF AMINO ACID PREPARATION AND FOLIAR FERTILIZERS ON MAIZE YIELD AND QUALITY pag. 83-90
Z. FUTÓ*, G. BENCZEWe made the foliar fertilization experiments in the near of Szarvas in 2022 in cooperation with Hed-Land Hungária Ltd. The soil of the experimental area is deep carbonate chernozem meadow soil. The main characteristics of the soil of the experiment: its physical type is clay loam, its chemistry is acidic or weakly acidic, the cultivated layer does not contain CaCO3, based on the humus content, the N-supply of the soil is medium. In the experiment, 5 foliar fertilizer and amino acid treatments were examined, supplemented by an untreated control plot. The treatments had a positive effect on maize yields in the experiment. The achieved average yields increased by 7.80 – 25.61% the average yield of the control, untreated plots (7.56 – 9.37 t/ha). The average yield achieved in the treated plots reached the limit of the statistically difference, so the effect of the treatments was significant. The highest yield average was obtained in the 2x Aminocore 2 l/ha and Ionic Zn 0.2 l/ha treatments (9.37 t/ha). During the experiment, we also examined the changes in the quality of the maize grain. Protein%, starch%, and oil% were measured in the study. We were able to establish that no clear correlation could be established between the treatments and the quality parameters. The values measured in the untreated control plots sometimes improved and increased in the treated plots, while in other cases we could see a slight decrease. Amino acid preparations therefore have a significant effect on the average yield, the quality is more of a genetically determined property.

DownloadUPDATED HOST PLANT RANGE FOR PHYTOPHAGOUS INSECT COREUS MARGINATUS (HEMIPTERA:COREIDAE) IN ROMANIA* pag. 91-97
Ioana GROZEA, L. MOLNAR, A. CARABET, Ramona STEF, Monica BUTNARIU, Snejana DAMIANOV, A. GROZEA, Ana Maria VIRTEIUIn recent years, in the parks and gardens of urban and rural areas in Romania, the harmful species Coreus marginatus (Linnaeus, 1758) has been often observed. After analyzing the information set, we found that there is little information at the national and even international level about the phytophagous character and its host plants. Until recently, the species was not a problem. That's why we proposed that through the present work, we would see the causes that led to the increase in its population. Through our 2-year study, 2021-2022 in 4 places in western Romania, we noticed that the insect is present especially in areas with various plant species in warm springs and summers. From the findings, it is obvious that the species is frequent in great color variability, at a high and very high level/the analyzed plant (n=3; n=6) in the 2 urban localities compared to the rural localities, where it was present at a low and absent level (n= 1.0; n=0.0). The ornamental plants with host potential were identified as follows: Chaenomeles japonica, Rosa l., Lavandula sp., Magnolia liliiflora, Convallaria majalis but also spontaneous plants such as Cirsium arvense. Most specimens were found on Chaenomeles and Rosa, where both adults and nymphs were observed feeding on sap from leaves, stems, inflorescences or seeds from inflorescences. The warm sunny periods of the day are favorable for its activity. We can conclude that the species has harmful potential due to the population growth or widening of the range of host plants, but we suspect that it is also due to the high temperatures in the summer and the places protected from the wind in autumn.

DownloadBROWN MARMORATED STINK BUG (BMCB) IN THE CONDITIONS OF ROMANIA VS ALGERIA pag. 98-104
Ioana GROZEA1, Maroua DAHBI2, Marwa SIDHOUM2Through this work we want to do a comparative study between the distribution of Halyomorpha halys species in Romania and Algeria. We are also considering the exposure of the host plants through updating. The aim is to see if there are differences or similarities in frequency and feeding behavior in the two mentioned countries, considering that they are part of 2 different climatic zones. The species originating from China, arrived in Romania in 2015 and in Algeria much later, in 2021. Our searches showed that it is widespread all over Europe and only in 2 countries in North Africa. Which entitles us to note the ability to move or spread through the plant trade, most likely through Spain, which is very close to Algeria. It is clear that in Romania, the Brown marmorated stink bug (BMSB) species is much more advanced in terms of population size, but especially the range of host plants. So, 33 preferred plant species were identified in Romania but for Algeria the situation is still uncertain, which is explainable due to the recent entry. However, it is expected that the evolution in Algeria will be much faster as it is known that there are species that prefer heat and sunny days. Comparing the different climatic zones of the 2 countries, it can be concluded that BMCB is very adaptable to new conditions, from temperate continental ones to warm Mediterranean ones. And these will be new subjects of study for the scientific world, if it stops expanding considering the very high temperatures in the central and southern part of Algeria.

DownloadWATER IS CRITICALLY IMPORTANT FOR AGRICULTURE IN HAITI pag. 105-110
F. GUYVENCHY1, R. PAȘCALĂU1, Laura ȘMULEAC1, S. M. STANCIU1, A.C. IMBREA1Water is critically important for agriculture in Haiti, as it is for agriculture everywhere. Haiti's agriculture sector is heavily dependent on irrigation, particularly for the production of staple crops such as rice, beans, and maize. In Haiti, where much of the land is mountainous and rugged, irrigation systems can be particularly challenging to build and maintain. However, there are several important water systems in Haiti that help support agriculture. These include: Overall, the availability and reliability of water systems in Haiti are critical for the success of agriculture in the country. Improving water infrastructure and management is essential for increasing agricultural productivity and food security in Haiti. Haiti is a predominantly agricultural country, with over half of the population working in the agriculture sector. Agriculture is also a significant contributor to Haiti's economy, accounting for around 25% of the country's gross domestic product (GDP). However, agriculture in Haiti faces a number of challenges, including poor soil quality, limited access to modern farming technologies, and a lack of investment in infrastructure. One of the most significant challenges, however, is water scarcity. Haiti has a hot and humid tropical climate, with a rainy season that typically lasts from May to October. However, the distribution of rainfall is uneven, and droughts and water shortages are common, particularly in the dry season. This makes irrigation critical for agriculture in Haiti, particularly in areas that receive less rainfall.

DownloadLOCAL-SCALE DISTRIBUTION OF PRECIPITATION IN THE GROWING SEASON OF 2019 pag. 111-118
Roland Hudák, Béla GombosAgriculture, including crop cultivation, is the most weather- and climate-dependent economic activity. With the help of various weather-plant models and statistical correlation studies, it can be established that the average yield-increasing and yield-reducing effect of weather reaches or exceeds 20% for most economic plants. Precipitation is a climatic element which is showing extreme variability in space and time and the spatial distribution of precipitation is becoming more and more extreme year after year. Our research focused on the spatial distribution of precipitation on horizontal scale up to 1-2 km. We established a low cost rain gauge network with 18 plastic rain gauges which are widely used in the Hungarian private sphere in the settlement Csabacsűd located on the Great Hungarian Plain (N46.49°, E20.39°, 85 m above sea level) where we did daily measurements between May and September 2019. It was clearly visible in the results of the 4-month measurement program that the standard deviation and the CV value showed a decrease compared to the 2018 research year. However, larger differences were also detected this year with a difference of 8.8 mm in the case of a distance of 1400 meters. On 22.06.2019, a difference in the amount of precipitation of 3.7 mm was detected between two gauges located 220 meters apart. This value represents a difference of 1.68 mm/100 m. These data show that on-site measurements are needed in the growing season for practical agrometeorological purposes such as irrigation scheduling.

IBRAHIMA Adamou1, DEUGA Yvette1, STROIA Ciprian2In order to contribute of introducing indigenous plant species in soil fertility management, trials were conducted in pot and field at the University of Ngaoundéré to study the effect of leaf powders of Tithonia diversifolia, Terminalia glaucescens and Annona senegalensis on seed germination and plant growth of maize (Zea mays L.). Leaf powder samples were mixed with 0.5 kg of soil in pots at three doses (10, 20 and 30 g), then watered with distilled water every two days after sowing. For the plant growth, field experiments were carried out in 4 m x 1 m plots each, separated by 25 cm wide. Data were collected on germination rate in the pot and plant growth in the field. The results showed that the powders of the three plant species and their mixtures did not show toxic effects on seed germination at all three doses because the germination rate was higher than 50%. For all treatments and at all doses, the germination rate reached 100% at 12 DAS, with the exception of the control (80% of germination) and the three mixtures (AS+TD, AS+TG et AS+TD+TG) at the high dose (30g). Growth parameters such as plant height, leaf number and neck diameter, and plant biomass for all treatments were significantly (p˂ 0,001) higher than those of control, and the best amendment was the powder mixture of A. senegalensis and T. glaucescens, with height value of 103.07 cm, leaf number of 14.33, neck diameter of 14.49 mm, and plant biomass of 98.57g. Compared to the control, all treatments improved the soil C, N and P contents, and the best improvement provided by the mixture of leaf powders of A. senegalensis and T. glaucescens, with soil C, N and P contents of 2.40, 2.14 and 0.09% respectively. The three plant species leaf and their mixture under the conditions of these trials have been of great potential for improving the availability of soil nutrients by providing the quantity necessary for cultivation of maize without the addition of chemical fertilizers. These results would contribute to the agroforestry plant species choice to domesticate for management of soil fertility of the Ngaoundere savannahs of Cameroon in particular and those of Sudano-guinea savannahs in general.

Péter Jakab, Györgyi Csontos, Melinda Tar, István KristóThe aim of our study was to evaluate the effect of different foliar fertilizers on the yield and grain protein, oil and starch content of maize. The experiment was set up in 2021 at the Öthalom research station of the Hungarian University of Agriculture and Life Sciences in Szeged. The soil was deeply salt meadow chernozem. Its nitrogen content was medium, phosphorus and potassium content was good. The experiment was carried out in three replications, using random blocks design. The size of plots were 14 m2. The produced maize hybrid was DKC 4555 (FAO 350). We sprayed three foliar fertilizers individually and combined with each other. We processed the obtained data by single factor variant analysis. 2021 was unfavourable year for maize. The amount of precipitation was lower by 113.58 mm than the average in the vegetative period of maize, therefore we got relatively low yields. The yield amount of control plot was 2.44 t ha-1. As a result of lack of precipitation the foliar fertilizers resulted low yield increasing (0.04-0.7 t/ha) which was not significant. The highest yield (3.14 t ha-1) we got in Amalgerol+Fitohorm Zn treatment. The foliar fertilizers resulted minimal and not significant changes in maize grain protein, starch and oil contents. We can conclude, that in unfavourable relatively dry year caused low effectiveness of foliar fertilizers in maize production.

R. C. JURCUȚ, F. IMBREA, L. BOTOȘ, S. BĂTRÎNASoy is an important crop with a long history of use in food, medicine, and industry. It is a critical source of protein, carbohydrates, and healthy fats for both humans and animals. Additionally, soybean plants have the unique ability to improve soil quality. One of the key factors in soybean production is germination, which determines the plant's growth rate and overall performance. To evaluate the sustainability of soybean varieties, a study was conducted to compare the germination rates of 24 soybean varieties to performance standards in the literature. The study found significant differences in germination and seed quality among the 24 tested soybean varieties, highlighting the importance of evaluating germination as a key indicator of soybean variety sustainability. The evaluation of germination can be a useful and straightforward method for assessing the quality and yield potential of soybean crops. By assessing germination as part of the soybean selection process, producers can identify which varieties are best suited for their growing conditions and improve the quality and yield of their soybean crops. In conclusion, the study emphasizes the importance of sustainable soybean production and highlights the potential benefits of evaluating germination as a key factor in the selection of soybean varieties for production. By using a variety of tools and approaches to evaluate the sustainability of soybean crops, we can help ensure that these critical resources continue to support human nutrition and the global economy for generations to come.

DownloadREVIEW STUDY ON THE SUSTAINABLE USE OF CHEMICAL FERTILIZERS IN SOYBEAN CULTURE pag. 145-151
R. C. JURCUȚ, F. IMBREA, L. BOTOȘ, S. BĂTRÎNASoybean cultivation is important for providing sustainable, high-quality production and protecting the environment. The responsible and sustainable use of chemical fertilizers is essential to achieve this. There are several key aspects to consider in using chemical fertilizers sustainably. Firstly, the correct dosing of fertilizers is important to prevent soil and groundwater pollution and avoid inefficient use of resources. The amount of fertilizer needed should be calculated based on the crop's needs and soil characteristics. Secondly, slow-release or controlled-release fertilizers should be used to release nutrients gradually during the plant's growth season. This can reduce nutrient loss through rainwater runoff or evaporation. Additionally, the use of organic fertilizers, such as manure or compost, can help improve soil fertility and maintain soil health. Modern technologies such as precision agriculture can also help use chemical fertilizers more efficiently and precisely, reducing the amount required and the impact on the environment. Regular monitoring of soil nutrient levels is also essential to avoid overuse of fertilizers and prevent soil and groundwater pollution. Overall, a responsible and sustainable approach to using chemical fertilizers is important to ensure healthy, abundant, and non-polluting soybean crops, contributing to the protection of the environment and the development of sustainable agriculture. By implementing these key aspects, we can achieve a balance between meeting our agricultural needs and protecting the environment.

DownloadDROUGHT STRESS INVESTIGATION OF DIFFERENT MAIZE HYBRIDS pag. 152-158
Ádám Komlósi, Gábor Bencze, Zoltán FutóThe head of the research is to investigate the effects of mild salt and drought stress on different maize hybrids. The research was set up at 2022 in Szarvas in the area of Hungarian University Agricultural and Life Sciences Department of Irrigation and Melioration. In the research below, we examined the responses of different maize hybrids to mild salt stress and different irrigation treatments. The research was protected from the natural rain, so we taked this research under a foil tent. In the experiment, we set up 3 different water doses and a mild salty treatment with the 3 water doses, and these were set up in several repetitions. We measured various phenological parameters on the maize several times during the research, and the final biomass weight at harvest of the experiment. In the research, we examined and analyzed the importance of hybrid selection and irrigation. In the course of the research, we measured the photosynthetic activity and different phenological parameters of different maize hybrids in a pot experiment. During the experiment, drought-sensitive and tolerant hybrids were tested under saline and non-saline conditions. During the experiment, plant height, leaf area (LAI) and relative chlorophyll content (SPAD) were measured every 2 weeks. In today’s climate-burdened world, we are increasingly confronted with the negative effects of drought and salt stress, but if we can prepare for and counter them, we can simply have a positive impact on our crop results. The experiment sheds light on how much a simple hybrid choice can affect our yield in a drought or normal year, or even on a saline soil. The novelty of the topic lies in the hybrids and field irrigation / water management results can be further refined for hybrids and soil hybrid and soil-specific irrigation adapted can be use.

DownloadTHE EFFECT OF FOLIAR FERTILIZATION ON INCREASING YIELD AND OIL CONTENT IN SUNFLOWER (HELIANTHUS ANNUUS L.) CULTIVATION pag. 159-169
P. KRIZSÁN1, Ágnes Tóthné TÓTH1, G. BENCZE1Foliar fertilization, which complements successful artificial fertilization, is becoming more and more widespread in Hungary as well, which provides the plant with a more reliable or additional supply of nutrients, especially in drier periods. In a year with a lack of rainfall - when the plant is not able to absorb the right amount of nutrients from the soil - the nutrient applied through the leaves can be a huge help, which can play an important role in its development, crop set, and content. Our research below serves to prove this, where in the case of sunflower we examined whether foliar fertilization results in an increase in yield and oil content in a year with a very low rainfall and atmospheric drought. The experiment was carried out in 2022 in Szarvas. In the experiment, in the case of 4 nutrient levels with different fertilizer doses, we also used additional foliar fertilization treatment, which was examined in 4 repetitions. The 4 different treatments were as follows: Control (without fertilization), Environmental protection level, Balance level, Genesis regional. In order to investigate the utilization of the applied nutrients, we carried out various yield tests and calculations, as well as internal content measurements. During the experiment, it was established that foliar fertilization resulted in a higher crop yield both in the case of no fertilization and in the case of the 3 nutrient levels, and it also increased the oil content of most treatments.

DownloadFORECASTING THE DROUGHT INTERVALS IN THE SOUTH-WESTERN PART OF ROMANIA pag. 170-174
V. MARAZAN, Ionela, BOLDIZSAR, Codruta, CHIS, Casiana MIHUT, Laura SMULEAC, Hortensia RADULESCUThe study presents a mathematical interpretation of the drought periods from 2010 to 2015 and the relationship between the drought periods and the associated baric structures at the European level. There is an increase compared to the climatological norm of positive temperature anomalies at the level of 500 hPa for almost the entire frame of the year, the only exception being the winter period. The maximum period of time characterized by a positive temperature anomaly at the level of 500 hPa is found during the summer months, when a sustained transport of air masses of tropical origin to the western area of Romania is noted. Periods of positive temperature anomaly at the 500 hPa level range from a minimum of 10 days to nearly 50 days during the summer. The period of negative anomalies varies between 7 days and approximately 40 days, the longest duration being during the winter months. From the analysis correlated with the arrangement of the baric centres, certain trends of the drought installation periods can be established, especially in the case of interpolation between the meteorological data and the analyses at the synoptic level. Although there may be short periods characterized by atmospheric instability during the summer, there is an accentuated humidity deficit that cannot compensate for the increased rate of potential evapotranspiration. The present study represents an intermediate analysis of the situation from a longer period.

Muhammad, F. M., A. Ahmed, M. A. Mohammed, A. A. Sadiq, Iaroslav Laţo, Alina LaţoA field trial was conducted during the wet season of 2020 at the research farm of the Institute for Agricultural Research, Ahmadu Bello University, Zaria; located at Samaru in the Northern Guinea Savanna of Nigeria. Treatments consisted of trellising; trellised and non-trellised and fertilization; control (0 t ha-1), Biochar (2 t ha-1) and NPK Fertilizer (100:50:50 ha-1). The treatments were factorially combined and laid out in randomized complete block design (RCBD) with three replications. The plots were marked out into 3 x 4 m in size with a spacing of 1.5 m and 2 m between plots and replicates respectively. Stand count, weed dry weight and leaf Area Index were not affected by trellising and fertilization at both sampling periods. Application of NPK at 100:50:50 kg ha-1 and biochar at 2 t ha-1 showed significant increase in number of branches and vine length with better results when influenced by trellising than control and non-trellised plants. There was no significant difference in the number of days to 50% flowering in cucumber with control showing the lowest days. Furthermore, Application of NPK at 100:50:50 kg ha-1 and biochar at 2 t ha-1 demonstrated significantly higher number of fruits, fruit length, fruit diameter, fruit weight and fruit yield with the best results as influenced by trellising. Data was collected on weed count, weed dry weight, vine length, number of leaves of plant, number of flowers, number of days to 50% flowering, plant length and plant weight. Data collected were subjected to analysis of variance (ANOVA), and means separated using Duncan Multiple Range Test.

KNAP3The basic concepts of climate change include:The greenhouse effect is a natural process that occurs when certain gases in the atmosphere, such as carbon dioxide (CO2), water vapor, and methane, trap heat from the sun, which warms the Earth's surface. Anthropogenic climate change refers to the current and ongoing changes to the Earth's climate system, largely caused by human activities, such as burning fossil fuels, deforestation, and industrial processes, which increase the amount of greenhouse gases in the atmosphere. Global warming is the ongoing increase in the Earth's average surface temperature, primarily caused by the buildup of greenhouse gases in the atmosphere. Climate feedback loops are processes in which changes in the climate system amplify or reduce the magnitude of the initial change. For example, melting polar ice caps can cause sea levels to rise, which can lead to further warming and melting of ice. Climate forcings are external factors that drive changes in the climate system, such as changes in solar radiation, volcanic eruptions, and greenhouse gas emissions. Climate sensitivity is a measure of how much the Earth's average temperature would change in response to a doubling of atmospheric CO2 concentrations. Climate impacts refer to the effects of climate change on the environment, human societies, and economies, including changes in precipitation patterns, sea level rise, and impacts on agriculture, forestry, water resources, and human health. In conclusion, the basic concepts of climate change include the greenhouse effect, anthropogenic climate change, global warming, climate feedback loops, climate forcings, climate sensitivity, and climate impacts. Understanding these concepts is crucial to understanding the nature and causes of climate change, as well as the actions that can be taken to address the issue.

DownloadTOXIC POTENTIAL GENERATED BY NITRATE CONCENTRATION IN FOOD AND DRINKING WATER RESOURCES pag. 199-204
Hortensia RĂDULESCU1, Laura ȘMULEAC1The paper shows the existence of a toxic potential in the rural population food resources because of their nitrate concentration in vegetables and drinking water as a result of intensive agricultural practices. For this purpose, the nitrate content of the main vegetables cultivated by farmers and that of the well water used for drinking and watering, was established. The variation of nitrate content and the estimation of nitric overload in the village areas from the south -west area of our country have been pursuit in several localities, representative for their large vegetable yields, being a major source for the town market supply. Simultaneously with the consumption of vegetables, the nitrate ingestion is completed by the consumption of drinking water having as water source the wells water representing together the daily nitrate intake. The nitric depreciation degree of the analysed food resources was determinate by percentage calculation of the maximum permissible limit exceed, specified for each analysed vegetable or water sample. Nitric toxicity through vegetable or water consumption can be estimated considering the food assortment ingested through the daily food diet and vegetable foodstuffs intake, the foodstuff nitrate content and the consumer’s weight. To avoid in time, the appearance of serious toxic consequences on human health generated through body nitrate accumulation, FAO and WHO have established 3,65 mg nitrate/ kg consumer weight, as daily admitted intake of nitrate, meaning also not to exceed 50 mg nitrate/ l drinking water. The usefulness of the paper consists in preventing the consumer’s nitric contamination by drinking water from rural wells and consuming overloaded vegetables with nitrates. Exceeding the toxicity limit mentioned above, may induce serious illnesses like methemoglobinemia and cancer.

DownloadGENETIC VARIABILITY AND MODE OF GENE ACTION OF DIFFERENT MATURITY GROUPS OF MAIZE (ZEA MAYS L.) INBRED LINES FOR DROUGHT TOLERANCE* pag. 205-218
Z. SAMINU*, M. OYEKUNLE*, K.I. LATO, Alina LATODrought tolerant maize (Zea mays L.) hybrids are crucial for the sustainability of maize production in the drought-prone areas of Sub-saharan Africa. Understanding the genetics of inheritance under drought is important in designing breeding strategies for improving grain yield and other agronomic traits under drought. Two studies were conducted to determine the the genetic variability and mode of gene action for grain yield and other traits of different maturity groups of maize inbreds for tolerance to drought and identify the promising drought-tolerant maize hybrid(s) for drought-prone regions. Eleven inbred lines of different maturity groups and endosperm-modification were crossed using diallel mating scheme to generate 55 F1 hybrids. The 55 hybrids along with one check and 11 inbreds were separately evaluated under induced drought and optimum growing conditions at Samaru and Kadawa. The experiments were laid in a 7 x 8 alpha lattice design and replicated two times using single-row plot of 4-m long. Row and hill spacing were 0.75 m and 0.4 m respectively. General combining ability (GCA) and Specific combining ability (SCA) mean squares were significant (p < 0.01) for grain yield and most other traits under drought and optimum growing conditions. SCA accounted for 79.3% and 64.2% of the total genetic variation for grain yield under drought and optimum growing conditions, indicating that non-additive gene action largely controlled the inheritance of grain yield of the hybrids. Hybrid TZEE-W-Pop STR C5 x TZEI 87 should be further tested in multiple environments for adoption by farmers in drought prone areas of Sub-saharan Africa.

DownloadPARTICIPATORY ON-FARM EVALUATION OF STRESS TOLERANT MAIZE VARIETIES AND HYBRIDS IN SOME NORTHERN STATES OF NIGERIA* pag. 219-228
Z. SAMINU1, M. OYEKUNLE1, Y. OLADIMEJI1, A.M. ABUBALAR1, K.I. LATO2, Alina LATO2Maize is one of the most planted crops in Nigeria and it accounts for the largest share of the country’s coarse grain production. Maize farming is carried out in nearly all the geographical zones in Nigeria. However, the bulk of the country’s maize production is concentrated in Kaduna, Katsina, Niger, Plateau, Taraba, Kano and Oyo. These maize producing states accounts for nearly two-third (64%) of maize produced in Nigeria. Current maize yield averages 1.7 t/ha and is barely sufficient for the region’s requirements due to drought, striga infestation and low N stresses. The objective of this study was to compare new stress tolerant maize hybrids and open pollinated varieties (OPVs) against the best released commercial varieties in Nigeria using farmer participatory approach and to validate on-station results. Maize varieties were simultaneously selected on-station from the different agro-ecology in Nigeria during the 2019/2020 and 2020/2021 seasons. During the season, 12 promising stress tolerant maize hybrids and OPVs among which are extra-early, early and intermediate were selected from the on-station based on their mean grain yield and stability. These selected varieties were compared with the best commercial check varieties on-farm across locations in Nigeria in a randomized complete block design. The genotype + genotype x environment comparison biplot showed hybrid AS1909-5, EWTH-14 together with other new stress tolerant hybrids and OPVs to be stable and high yielding on-station across locations compared to the commonly grown checks. This indicated that hybrid AS1909-5 and EWTH-14 possesses beneficial alleles that contributed to the observed superior performance when compared to the other hybrids.The new stress tolerant hybrids showed a yield advantage over the commercial check varieties both in the extra-early, early and the intermediate maturing categories, and the gains were bigger under stress conditions. Under farmers’ fields, DT STR Syn/TZL Comp.-W, 2015 DTE STR-Y Syn, AS1909-5, AS2001-16, EWTH-14 and EEPVAH-95 were high yielding and stable across locations and recommended for release.

DownloadTHE SWEET POTATO YIELD EFFECT OF CULTIVATION IN MONOCULTURE IN 2016-2022 pag. 229-234
ADRIENN SZARVAS 1, SUNDUSIN AFIQAH IZZATI BINTI2, ZHOU DAI,2 ÁDÁM BORDÉ1More and more people are growing sweet potatoes in Hungary, but no one has yet tested how long they can be grown successfully on the same soil type. This means the quantitative and qualitative variables of the yield. From 2016 to 2022, I planted sweet potato slips in the same area and after four years, the yields decrease significantly. To reduce problems caused by soilborne pathogens, a three to five year rotation of crops is recommended. In Deszk, we set up the experiment on a 300 m2 area for all seven years. Based on clay loam soil. The area was fallowed for 5 years before 2016 and then planted with sweet potatoes for seven years. We always used the same field, so sweet potatoes were grown in monoculture. We also used the practices of growers in the area for soil preparation and the application of soil disinfectant. There was a significant difference in yields between seven years (p<0.05), with the highest yield (41.01 t/ha) in 2018, followed by 2016 (37.19 t/ha) and the lowest yield in 2022 (10.01 t/ha) (p<0.05). The total rainfall and average temperature of the 2017 growing season were not favourable, which was also reflected in the yield to a significant extent. The year 2019 was 30 t/ha, which can be considered as good results. From 2020 onwards, we have seen a continuous decrease in yields, which can be attributed to the effect of monoculture. The studies show that sweet potatoes can be grown successfully on clay loam soil for four years. In the following years the yield significantly decreased. Thus, it is advisable to set the field aside after four years. I recommend the use of ridges techology because using rides technology the harvesting is much easier, there will be fewer damaged tubers and the tubers have more room to grow in the ridges. Soil-dwelling pests need to be controlled, as soil-dwelling pests can cause serious problems in crop quality. It is advisable to change soil disinfectants every two years so that soil-dwelling pests do not become resistant to the active ingredient.

STANA1, Viviane Beatrice BOTA1,3,4, Doina Carmenica JITĂREANU2Sunflower (Helianthus annuus L.) is one of the cultivated species with great use potential, which leads to as need of finding permanent solutions for the efficient valorisation of this plant as a source of lipids, proteins, and carbohydrates, especially in the context of the continuous diversification of energy sources and raw materials for the industrial and agricultural sectors. The paper analyses the reaction of Helianthus annuus L. genotypes to the soil, temperature, and humidity conditions of the Crișurilor Plain, in conjunction with the cultivation technology recommended for this species. The results were obtained during the years 2021 - 2022, the experiment being single-factor, in four replicates, with five established hybrids. The sunflower genotypes used as experimental variants were as follows: V1 - Performer; V2 - Ilinca 115; V3 - Inkasun IR; V4 - Bravo SU; V5 – Florasun. Among the parameters analysed in the tested hybrids, we mention: vegetation period, plant height, capitulum diameter, the mass of 1000 achenes, hectolitre mass of achenes, achene production, as well as percentage content of achenes in lipids, proteins, and carbohydrates. The results obtained were then interpreted in terms of economic efficiency, recommending the Crișurilor Plain as a suitable region for growing the tested hybrids.

Alina URLICA, Carmen DUMITRESCU, Marius Robert LUNGU, Iasmina IOSIMThe term “inclusive” has made a career in the last 15 years: there are at least 74 phrases containing this term, 18 of which belong to the field of agriculture, thus being of interest to our students: “inclusive agribusiness”, “inclusive (agricultural) market system”, “inclusive agricultural food system”, “inclusive agricultural value chain”, “inclusive agriculture / farming”, “inclusive business model”, “inclusive contract”, “inclusive development”, “inclusive growth”, “inclusive investment”, “inclusive market (access)”, “inclusive ownership”, “inclusive participation”, “inclusive regulation”, and “inclusive rural transformation”. This study is an attempt to clarify the meaning of the target language (inclusive agricultural phrases) and to see in what ways these are relevant to our holistic educational purposes. The term “inclusive” has been widely in use in recent years. It has been deemed useful by the authors of this study to identify phrases containing this term and to analyze their relationship to the field of natural sciences. We conclude that 18 terms from our studied corpus belong to the field of agriculture, therefore being relevant to the field of study of major interest to our students. Thirty-nine journals and official documents were browsed for studies regarding inclusive-labelled issues. The systematic literature review of original research articles was conducted considering the “Preferred Reporting Items for Systematic Literature Reviews and the Meta-Analyses (PRISMA)” method

Alina URLICA, Iasmina IOSIM, Veronica SARATEANU, Adalbert OKROS, Maria LUNGUBy conducting surveys and questionnaires, we have aimed at identifying the needs of students enrolled in academic programs within the domain of Natural and Life Sciences who also study English as a Foreign Language, as well as English for Specific Purposes. The analysis also targets students’ perceptions and attitude toward recently developed EFL material and prospected ESP textbook materials targeting “Ecological English”, as well as “English for the Life Sciences”. With this purpose in mind, we wish to make better use of the students’ feedback and be able to adapt our teaching materials to correspond to the learners’ genuine needs and interests. The qualitative analysis of the students’ feedback indicates that they are largely interested in understanding ecological processes and communication at all levels in nature. We also include examples of activities devised for the English language textbook, in the hope of developing optimized educational models and with a view to sharing best practices in foreign language teaching/learning. The major aim of our on-going interdisciplinary project is to promote chances of employability for students in natural science engineering and related areas, where communication remains an important issue. For this purpose, the specific aims which are targeted in the educational and English courses consist in the design of a set of didactic strategies informed by shared practices and the development of communicational learning materials.

RARES Vranceanu 1, ABUBAKAR Ahmed 1&2, YAHAYA Muhammad Ahmad 1&3, NAFULA Phelyster Kisambu 1&4, ARIANA Pizmas 1, MIHAI Herbei 1 and GEORGETA Pop 1.Abstract The study covers the behaviour of sorghum crop cultivated under the soil and climatic conditions of Buzias microzone. The soil type on which sorghum was grown was clay soil. To characterize the climatic conditions with the recorded monthly mean temperatures, data obtained from the Buzias Meteorological Station from 2021-2022 were used compared with the multi-year averages. Method of analysis Sorghum nutritional seed results are as follows: dry substance (92.41-90.33 %), crude protein, (10.97-10.10 %), crude cellulose (5.59-5.69 %), fats (4.87-4.66 %), mineral substances (2.19-2.31 %), carbohydrates rate (66.16-66.89 %), energetic value kcal (352.35-349.9 %). While that of humidity is (10.22-11.35 %). The grain yield achieved was between 2000-3500 kg/ha. Vegetation index values were also recorded by NDVI value ranges from -1 to 1 and shows the vigor of the cro, Misiunea Copernicus SENTINEL-2. Values close to 1: the more intense the green, the more vigorous the vegetation and vegetation cover. From a climatic point of view, 2021 was a dry year, with very little rainfall between May and June, which reduced grain production by 50%, although sorghum is a drought-resistant crop.Sorghum for grain is suitable for cultivation on heavy clay and loamy-clay soils, in the conditions of the Buzias area, being also a disease-resistant plant.
