Denisa Maria AIOANEI1, D. N. MANEA1, Anișoara Aurelia IENCIU1The purpose of this study was to demonstrate the efficacy of the herbicide Resital Duo (SE) against the weed Polygonum aviculare, from a winter wheat crop. The observations were made in a wheat crop located in the western part of Romania, respectively in the Western Plain. Research has been conducted during the agricultural years 2022-2023, and included determinations on the effects of vegetation treatments with the herbicide product Resital Duo (SE) (452.42 g/l 2.4-D 2-Ethylhexyl Ester (EHE) + 6.25 g/l Florasulam.), applied in 4 variants and 3 different doses (untrated, 0.2 l / ha, 0.4 l / ha, 0.6 l / ha. Therefore, a monofactorial experience was set up in the field, placed according to the method of randomized blocks, in four repetitions. 15 days after application of Resital Duo (SE) (452.42 g / l 2.4-D 2-Ethylhexyl Ester EHE) + 6.25 g / l Florasulam), the most effective treatments in experience were variant 3 (0.4 l / ha) and variant 4 (0.6 l / ha), with an efficacy of 57.5%, respectively 77.5%. After 30 days of the application of the Resital Duo (SE) product, the most effective treatments in our experience were both variant 3 (0.4 l/ha) and variant 4 (0.6 l/ha), which accumulated an efficacy of 92.5%, respectively 99.5%. The applied product did not create any kind of phytotoxicity to our crop, at any of the 3 doses tested, and the vigor of the wheat was maintained at the level of 100%;

DownloadTHE RELATIONSHIP BETWEEN THE LAND SURFACE TEMPERATURE AND NORMALIZED DIFFERENCE VEGETATION INDEX pag. 13-19
Codruta BADALUTA-MINDA 1, Andreea- Mihaela DUNCA 2In recent years, land cover / use has undergone major changes, and this aspect participate along with other factors in climate change both in our country and globally. Vegetation indices based on satellite images are increasingly used to characterize the response of vegetation to climate variability and change over large spatial scales. One of the parameters estimated based on remote sensing and used in the calculation of temperature interception is the LST index. This study proposes to evaluate the trend of the spatial-temporal relationship between land surface temperature (LST) and normalized difference vegetation index (NDVI) in different ranges of LST and NDVI values for Timis County. Vegetation is very sensitive to climate changes and various anthropogenic influences, and these variations of the NDVI index can cause changes in the temperature of the land surface. In the final part, the correlation between the spectral indices of land cover (NDVI and NDWI) with the soil surface temperature (LST) was made. The remote sensing images were processed using the Geographic Information System (GIS). This study highlights the association of the LST index with land cover indices, and from the obtained data it can be observed that the correlation between NDVI and LST is one negative.

B. AL BENNI¹, Veronica SĂRĂȚEANU ²*, Otilia COTUNA2*The present overview aims to statistically enlighten the similarities and differences of the agricultural sector between Romania and Turkey. Our overview uses official statistical data from the year 2021 to compare the agricultural sector of Romania and Turkey. The data of this study were collected from the National Institute of Statistics of Romania (NSI Romania) and from the Turkish Statistical Institute (TUIK). Also, Turkey is one of the largest wide-range agricultural product producers worldwide, with a 5.54 percent share of total gross domestic product (GDP) in 2021. In Romania, the share of the agricultural sector in 2021 was 4.4. Arable land represents 64.22% from the total agricultural land in Romania and 52.20% in Turkey; this fact highlighting the agricultural specificity of each of the analysed countries. The structure of the agricultural production is very different in the analysed countries, because the greatest productions in Romania are obtained by the cereals for grain and green fodder cultivated in arable land, while in Turkey the most important from the perspective of the production are fruits, nuts and vegetables. Turkey has a very divert range of vegetable crops, dominated from far by tomatoes, while in Romania cabbage and tomatoes are the greatest production. The sector of fruits and nuts in Turkey is represented by a great range of species, from those citrus fruits have the greatest production. In Romania, the greatest fruit production is given by grapes. Regarding the animal breeding, Romania has the greatest number of poultry, while in Turkey sheep are dominant. The greatest animal production in Romania was obtained in poultry sector and in Turkey in the raw milk. The latest available data on agricultural sector of Romanian and Turkey shows that both agricultural sectors are complementary.

Ionela BOLDIZSAR2, V. MĂRĂZAN1,2, Antoanela COZMA2, Hortensia RĂDULESCU2The purpose of the present study is to present a climatology of stormy phenomena in the western part of Romania for the period 1991-2020. The climatological norm chosen is significant for current research due to the fact that the data available after 2010 are of high accuracy and can be integrated in other specialized studies in the fields of agriculture, civil engineering, energy and construction. In the study, observational data from the integrated meteorological system of aviation, satellite data and RADAR parameters were used to characterize the convective formations that produce these stormy phenomena. The choice of the western area of Romania is significant because the predominant zonal circulation brings moisture and conditioned unstable air into the researched area. It is also worth noting that stations from different orographic areas in the western part of Romania were chosen precisely to allow the performance of conclusive statistics for the entire research area. In this studio, the aero-synoptic situations that can trigger stormy phenomena were also taken into account outside of the late spring and summer season, a period specific to the manifestations of atmospheric instability. It was concluded that the transitional seasons present a high frequency of electrical discharges, and during the summer an increase in the duration of electrical discharges is noted.

B. COZMA1, V. MĂRĂZAN1, Iasmina Madalina ANGHEL2, Antoanela COZMA1, Hortensia RADULESCU1The purpose of this paper is to obtain and characterize the chicken eggshells results as domestic waste in order to use them for blocking lead and cadmium in acid soils contaminated with heavy metals. Practically, was determined the effectiveness of fixing lead and cadmium in moderately acidic soil, which contains amounts of lead and cadmium above the intervention level, in the case of using eggshell powder (EGP) in proportions of 1 and 5 percent (compared to soil). The obtained results show different values of the effectiveness of blocking Pb and Cd, depending on the amount of eggshell used and the nature of the metal. Higher values of effectiveness have been reported in the case of using of 5 percent eggshell powder. Comparing the efficiency of using EGP it can be seen that the method is more efficient in case of blocking cadmium. Also, the use of the eggshells powder contributes to reducing the acidity of the soil. The obtained results recommend the use of eggshells for Pb and Cd fixation from acid soils contaminated with such heavy metals contributing to the soils rehabilitation, unsuitable for growing plants. Superior utilization of eggshell waste can be an efficient way of neutralizing them from agro-industrial activities.

Roxana DRAGOMIR1, Diana TET1,, Bianca ROTARIU1, I. GAICA1, Madalina BORCAFrom the perimeter of the agricultural holding, soil samples were collected under study in order to establish the state of soil fertility. The limiting factors of the soil fertility were identified. The production capacity of soils is influenced by a series of limiting factors, among which the most representative are: soil reaction, humus reserve, and the low content of nutritive elements. Depending on the restrictive elements presented, calcium amendment measures, ameliorative fertilizing, works to correct the aero hydric regime of the soil, and the professional application of agricultural technologies are required for intensive exploitation of agricultural land in ecological parameters. On the evaluated soils there can be observed an acidic and very acidic reaction which has started to block phosphorus. For now, the potassium levels are very good but the acidification process will continue, because calcium is being utilized as food, and is being consumed from the superficial layer, which causes the soil to continuously acidify. Acidification also occurs from most acidifying fertilizers. Acidic soils are soils lacking in basic cations and the colloidal complex transfer - the soil solution that is unfavorable for plant nutrition. As a result, it is recommended that the basic fertilization, when preparing the land, be carried out with manure, a complex fertilizer that improves activity in soil microbial life and nutritive elements in the soil

Andreea-Mihaela DUNCA1, Codruța BĂDĂLUȚĂ-MINDA2Climate change generates not only concern about the climate future of the planet, but also great material damages, in the most diverse areas of social life, causing phenomena that seem to irreversibly change the face of the world and implicitly the general conditions of life. The series of meteorological data (air temperature and atmospheric precipitation), from the Lugoj meteorological station were used to identify and highlight the conditions of occurrence and manifestation of climate changes that took place in the western part of Romania and in the last 60 years, from 1961 until 2020. Climatic elements and phenomena are interconnected to such a great extent that on a global scale it is necessary to recognize a "climate system", governed by its own laws, which determine both its configuration at a given moment and its evolution over time. As a consequence of the global climate changes we are witnessing, it can be observed, analyzing the variability and evolution trend of the thermal regime of the air over the last 60 years, that the evolution trend of the multi annual average temperature at the Lugoj meteorological station is increasing with a value of about 1.7° C. In the context of global climate changes, the distribution of precipitation by seasons in this part of the country where the Lugoj meteorological station is situated, follows quite different trends over the last 60 years, namely: a constant trend is recorded in summer, a trend decreasing in spring and winter is recorded decrease and in the fall there is a more pronounced upward trend, which in total cancels the decreases during the spring and winter.

DownloadTHE OPTIMAL CONTENT OF FATTY ACIDS FOR HEALTHY NUTRITION pag. 75-81
Tamara Edina GAL, Carmen Giulia CUCOS, Iulia Daniela FÜR, Olga-Alina RADA, Iuliana POPESCU*Diabetes and obesity are pathologies that have a worldwide spread. The fact that food has become very easily accessible, and the physical effort we do every day is less and less, can be an explanation for the increased rate of obesity nowadays. Starting from the traditional Mediterranean diet, which is characterized by a high intake of monounsaturated fats (eg olive oil, nuts), a low intake of saturated fats (eg red meat) and a moderate intake of polyunsaturated fats and long-chain omega-3 fatty acids (from fish and seafood), a solution could be found to ensure the optimal intake of fatty acids. The present study reviews the fatty acid profile of olive oil and walnut oil samples, both major components of the Mediterranean diet, as well as their mixtures in different proportions, proposing to identify the proportion that ensures the optimal ratio of monounsaturated fatty acids/polyunsaturated, respectively omega-6/omega-3 fatty acids. Gas chromatography-mass spectrometry (GC-MS) analysis showed that there is no significant difference between the fatty acid content of extra virgin olive oil (EVOO) and BIO olive oil, and the same is true for BIO walnut oil and walnut. In the case of the oil mixtures used in the experiment, the fatty acid profile is close to optimal for olive oil/walnut oil 1:2. The following conclusions were drawn: the ratio of mono and polyunsaturated fatty acids in the human diet should be 1:2, and that of omega-6 (linoleic acid) and omega-3 (linolenic acid) fatty acids would ideally be 1:1. In the case of saturated fatty acids, their weight should not exceed 15% of a healthy diet.

A. E. GHIMAN 1 , A. DRACEA1, N. BAGHINA1 , Adina HORABLAGA1Nowadays, the need of efficient methods of waste disposal and further treatment are required most than never, due to high rate of worldwide usage of primary matter and resulting waste. This matter is also strongly linked to the ecosystem challenges and healthcare problems, raising serious challenges all around the world. The negative impact on the environment and human health still represents a risk to human health as a result of waste disposal related to inappropriate methods and technologies for waste handling, Sustainable development is conditioned by environmental protection and waste management plays an important role in the concept of sustainable development. Even if waste does represent one of the most important source of pollution, but properly managed, it can also be used as a source for secondary raw materials, with the proper management. By landfill we mean a site for the final disposal of waste by landfill or underground. Final disposal of waste, if the waste cannot be recovered, it must be disposed of safely for the environment and human health, with a strict monitoring program. At EU level, municipal waste is treated by landfill (38%), incineration (22%), recycling (25%) and composting (15%). Actual situation in Romania, still has to deal with storage as the dominant method for waste disposal. Controlled storage is widely used in the world and remains the main system for storing and neutralizing household waste until processing systems for the selection and recovery of materials and potential energy will develop and gain priority in their application. The current legislation on the development of waste storage, leads to the progressive reduction of recyclable waste.. This paper describes the activity of controlled waste storage and monitoring system in the landfill of non-hazardous waste in Ghizela commune, Timiș county.

Cătălina GÎRJAN, Liana BUTTA, Ilinca IMBREAThe present scientific paper presents the results of the effects of treatments with essential oils of crimson beebalm (Monarda didyma) and wild thyme (Thymus pulegioides), at different concentrations (25μl/ml and 50 μl/ml), on the germination of soybean (Glycine max) seeds, considering the antifungal and antibacterial properties of the essential oils mentioned above. Soybean seeds represent one of the most important sources of vegetable protein, widely cultivated throughout the world. To evaluate the phytotoxicity of essential oils on the seed germination process, two experiments were realized: one in vitro and one in vivo. It was observed that the application of Monarda didyma and Thymus pulegioides essential oil treatments, at different concentrations, did not negatively influence the germination percentage of soybean seeds, but caused a reduction/inhibition of root size development. The in vivo experiment showed an inhibitory effect of the tested oils on the development of vegetative organs of soybean plants compared to plants in the control group not treated with essential oils. Based on the antifungal and antibacterial properties of the oils analysed, as well as the results obtained in the in vitro experiment following the application of essential oil treatments on soybean seeds, the use of the oils studied, can be taken into acount as possible ecofriendly fungicides in grain storage.

DownloadIMPACT OF WATER POLLUTION ON ANIMAL BREEDING: AN ECOLOGICAL CONUNDRUM pag. 138-144
D. LEAH 1, Ș. ZOICAN 1, L. VORNICU 1, Laura ȘMULEAC 1, R. PAȘCALĂU 1Water pollution stands as a formidable global challenge, casting a pervasive shadow over ecosystems and profoundly impacting animal breeding, both on land and in water. This abstract serves as a clarion call, illuminating the intricate dynamics between water pollution and the reproductive processes of a diverse spectrum of species. A litany of contaminants—ranging from heavy metals to pesticides and emerging pollutants—infuses water bodies, disrupting the delicate balance of nature's reproductive cycles. The consequences reverberate through the animal kingdom, manifesting in manifold ways. The insidious influence of water pollution spans reduced fertility rates, genetic aberrations, and population decline across species. The insinuation of pollutants into the environment also skews behavioural patterns, altering mating rituals, migration behaviours, and the overall viability of animal populations. Moreover, the pernicious effects of water pollution extend beyond individual organisms to imperil entire ecosystems. Aquatic biodiversity suffers as pollution erodes crucial habitats and fractures intricate food chains, leading to cascading repercussions throughout the ecosystem's trophic levels. The decline in species diversity not only threatens the intrinsic value of varied life forms but also disrupts the ecological balance, potentially leading to unforeseen and deleterious consequences for the environment as a whole. Consequently, the urgency to address this multifaceted challenge becomes apparent. The abstract serves as an introductory gateway, emphasizing the imperative for comprehensive and meticulous scientific inquiry. It underscores the necessity for stringent regulations and innovative, sustainable practices to curtail and counteract the detrimental effects of water pollution on animal breeding and broader biodiversity. A comprehensive exploration beckons, delving deeper into this ecological conundrum, unravelling the complex interconnections between water pollution and the intricate tapestry of animal breeding. It calls for collaborative efforts across scientific disciplines, policy-making arenas, and global communities to staunch the flow of pollutants into our waters and safeguard the reproductive health of diverse animal species. Ultimately, it advocates for a conscientious commitment to conservation, research, and proactive measures to mitigate the pervasive impacts of water pollution on animal breeding and the resilience of ecosystems worldwide.

DownloadELEVATING RURAL COMMUNITIES THROUGH AGRICULTURE AND ANIMAL HUSBANDRY pag. 145-151
D. LEAH 1, C. ZOICAN 1, R. JIGĂU 1, P. MERGHEȘ1, R. PAȘCALĂU 1The revitalization of rural areas through farming and animal breeding has become a central focus in sustainable development strategies worldwide. This abstract highlights the multifaceted impact of these two interrelated practices on rural communities. Agriculture and animal husbandry play crucial roles in the well-being of rural areas. Agriculture is not just about producing food; it is a foundation for economic growth and stability. By harnessing modern agricultural techniques, such as precision farming and sustainable agriculture practices, rural communities can significantly increase their agricultural productivity. Crop diversification can help reduce the risks associated with monoculture and promote sustainable land use. Additionally, agroforestry and organic farming practices can enhance the environmental sustainability of farming, benefitting not only the local community but also the planet. In tandem with agriculture, animal breeding has a profound impact on rural development. Improved livestock breeding programs can enhance the quality and yield of animal products, including meat, milk, and wool. These enhancements, in turn, generate economic opportunities for rural communities. The development of specialized breeds adapted to local conditions can further strengthen the resilience of rural economies. Moreover, the relationship between agriculture and animal husbandry extends to a broader social context. These activities foster social cohesion by encouraging communal participation, shared knowledge, and cooperation. Rural areas often rely on tight-knit communities, and these practices further strengthen the social fabric by creating common goals and shared responsibilities. The success of these efforts relies on informed policies, technology adoption, and knowledge transfer. Governments and organizations need to implement policies that support sustainable agriculture and livestock breeding practices. Access to modern technology and training is vital to ensure rural communities can benefit from the latest advancements. Effective knowledge transfer programs can equip individuals with the skills and information needed to thrive in a changing agricultural landscape.

DownloadSTUDIES REGARDING THE TECHNICAL AND OPERATIONAL CHARACTERISTICS OF THE SCARIFIED AGGREGATE pag. 161-169
F. MLADIN, G. VĂCĂRESCU, Anișoara DUMA COPCEA, Casiana MIHUȚThe purpose of this work is to study the technical characteristics of an aggregate to be scarified under the conditions of the classic soil processing system. When preparing the land for plowing, the following operations will be performed: - checking and removing the causes that can cause the creation of unfavorable conditions for the work of the machines; - the delimitation of return zones and the choice of the most efficient methods of travel; - dividing the land into plots and marking the line for the first crossing. For the performance of mechanized works, the plots are chosen in such a way as to ensure the work for a longer time, without switching to other plots. The minimum plot size must ensure work on at least one shift. After choosing the direction of travel, the turning areas are demarcated at the ends of the plot. At the beginning, the turning area is delimited by stakes, after which a furrow is drawn to a depth of 6 - 8 cm. These traces show the place where the scarifier was moved into the transport and working position. Return areas are worked after the work on the plot is finished. The concept of soil conservation includes a set of activities, measures and technologies that compete to maintain the state of soil fertility without significantly reducing harvests or without high costs. This concept arose from the considerations that the land is the most important means of human existence that ensures the obtaining of food products, raw materials for the energy industry, etc. and consequently maintaining the biological capacity is a necessity imposed by the existence of social life.

DownloadIMPORTANCE AND IMPACT OF MODERN LANGUAGES AND EDUCATION IN AGRICULTURE pag. 183-189
R. PAȘCALĂU 1, Laura ȘMULEAC1, S. STANCIU1, S. MILANCOVIC2, L.R. STIEGELBAUER2, A. PĂDUREAN3, A. URSA4In an increasingly globalized world, the importance of modern languages and education in the field of agriculture cannot be overstated. This extended abstract delves deeper into the multifaceted impact of language proficiency and education on agricultural practices and global integration. Agriculture is not confined to local or national boundaries; it has become a complex global network where farmers, researchers, and agricultural professionals interact with counterparts from diverse linguistic and cultural backgrounds. Proficiency in modern languages, besides being a means of communication, is a bridge to understanding diverse agricultural practices and perspectives from around the world. Access to research and information is a cornerstone of agricultural progress. Agricultural knowledge is disseminated in various languages, and the ability to comprehend and engage with research publications, technological manuals, and market trends in different languages is a valuable asset. Modern languages are the key that unlocks a treasure trove of information, enabling individuals in agriculture to stay informed and adapt to the latest developments. International trade and export opportunities are pivotal for many countries' economies. Agriculture plays a significant role in global trade, and language proficiency aids in negotiation, market analysis, and the fulfilment of international regulations. Effective communication in the right language is often the difference between success and failure in international markets. Cross-cultural understanding is integral to building fruitful relationships and collaborations. Misunderstandings, cultural insensitivity, or miscommunications can hinder agricultural cooperation and innovation. The ability to navigate cultural nuances and communicate effectively across borders fosters stronger international ties and paves the way for collaborative efforts in research, technology transfer, and sustainable farming practices.

L. PATRUNO1, V. M. SELLITTO1, N. M. HORABLAGA1, 2, D. RECHIȚEAN1,2, Veronica SĂRĂȚEANU1*, , F. IMBREA1*While in the atmosphere nitrogen is abundant, this element plays a limited role as nutrient for plants. Cereal crops, as an example, are uncapable to directly use freely available nitrogen gas. As a consequence, their optimal growing and, in general, the productivity of such crops relies mainly on the use of chemical fertilizers, which, under the European Green Deal and the Farm to Fork Strategy are under scrutiny with plans of reduction of their use. As increasing crop production is a vital target for agriculture and food systems, the role of nitrogen fixers could play a fundamental role to match the targets of increasing the food production by decreasing the use of chemical fertilizers. Also, such approach is very appropriate from the perspective of sustainable production and conservative agriculture. The present work has the objective to examine the role of nitrogen fixers on the maize yield, respectively the productivity in harvested maize crop treated with Azotobacter chrococcum, Azotobacter vinelandii and Bacillus megaterium, three different nitrogen-fixing bacteria. The investigations were based on field tests. Thus, there at the beginning the seeds were inoculated before seeding; and during the vegetation the crops were treated with the three bacteria species. The fields experiment was organized in four variants (one non-treated variant and three with the bacteria Azotobacter chrococcum, Azotobacter vinelandii and Bacillus megaterium) and three replicates. The examination of collected samples revealed a general increase in productivity in the variants treated with Azotobacter vinelandii.

V. RADA1, Adina HORABLAGA1This paper serves two key purposes. Firstly, it offers a glimpse into research conducted for a dissertation thesis, focusing on short food supply chains, food security, socio-economic aspects of the Central European rural landscape, and agricultural public policies. Secondly, it establishes a bridge between this thesis and forthcoming, more extensive studies on these subjects. The analyses extracted from the dissertation underpin the proposed hypothesis that the EU's current development directions present a significant opportunity for Romania to narrow the gap between its agricultural system and those of developed European nations. The research consists of two core components: (i) a concise exploration of the historical evolution of European goods supply networks, demonstrating how short-distance trade relationships have been integral to the continent's economic fabric for centuries and offering insights into the current status quo, and (ii) a preliminary assessment of Romania's agricultural landscape by categorizing its counties based on the legal status and agricultural holdings' dimensions. The findings suggest that Bihor County is well-suited as a testbed for innovative strategies aimed at the effective implementation of current European development directions within the Central European and Romanian contexts. Literary and quantitative investigation methods have been used. Anyways, even if these studies might shed some light in a still-cloudy realm, they are far from being profound enough. The number of consulted documents must increase and the calculations need to take into consideration more parameters to get more definite results.

Denisa-Daliana SFIRCULUS, Ioana GROZEAPhyllophagous insects that feed on the leaves of trees and shrubs in deciduous forests cause qualitative and quantitative damage to these natural ecosystems, true sources of oxygen. The current study aims to be an update of the information on the range of important pests in Romanian deciduous forests with continental extrapolation. An evaluation of the existing database (mainly from electronic sources but also from the physical bibliography) clearly shows that most of the pest species that are currently a problem for all deciduous forests in any area of the country belong to the orders Hemiptera (10) and Lepidoptera (8). Besides these, other categories of Coleoptera (2), Diptera (2), Orthoptera and Hymenoptera (1) were quantified. Stink bugs, aphids, tingids and cycads constituted the Hemiptera group with 41.66% of the total pests and Lepidoptera (which includes both moths and large butterflies) represented 33.33%. The remaining 25.31% is composed of leaf beetles, mining flies, bush-crickets and sawflies. All of these have the ability, both individually and together, to cause tree loss and to spread and infest new areas. Updating databases and initiating periodic monitoring activities in all forests, regardless of region, are ways of raising awareness of potential economic losses and, first of all, that they lead to the weakening of the main oxygen-producing sources.

DownloadTHE NECESSITY OF IRRIGATING CROPS IN THE WESTERN ROMANIA pag. 224-232
Laura ȘMULEAC, A. ȘMULEAC, F. IMBREA, R. PAȘCALĂUThe necessity of crop irrigation in Western Romania is intimately linked to the region's agricultural sustainability. Varying topography and soil characteristics across this area demand tailored irrigation approaches to meet the diverse needs of different crops. Efficient water distribution systems, coupled with soil moisture management techniques, play a pivotal role in optimizing irrigation effectiveness. The imperative for irrigation intensifies during periods of prolonged drought, where the reliability of rainfall becomes uncertain, affecting crop growth and yield potential. Moreover, acknowledging the necessity of crop irrigation in Western Romania prompts the exploration of water-saving methodologies, emphasizing the importance of conservation and recycling practices. In this article, the water deficit of the last 10 years was analysed in the conditions of Timisoara. It was observed that the plants' water needs are not covered by the rainfall. In these conditions, it is necessary to supplement the water through irrigation systems. Recognizing the necessity of irrigation for crops in Western Romania is not solely an agricultural concern but also a pivotal factor in ensuring regional food security and economic stability. As climate change impacts continue to pose challenges, investing in irrigation infrastructure and sustainable water management becomes indispensable for preserving agricultural livelihoods and securing food production in this vital region.

Ionela SPOREA, Liana BUTTA, Ilinca IMBREAThe present scientific work presents the results of the effects of lavandin (Lavandula x intermedia) and marjoram (Origanum majorana) essential oil treatments at different concentrations (25 and 50 μl/ml, respectively) on the germination of maize seeds, considering the antifungal and antibacterial properties of the essential oils mentioned above. The essential oils were obtained by hydrodistillation of the aerial of the plants. To evaluate the phytotoxicity of lavandin and marjoram essential oils, on the germination process of maize seeds, an in vitro experiment was performed. The experiment showed that the application of lavandin essential oil at a concentration of 25 μl/ml has a beneficial effect on the germination process of maize seeds, causing stimulation of the development of vegetative organs. On the other hand, increasing the concentration from 25 μl/ml to 50 μl/ml, produced an inhibition of corn pore germination, thus obtaining a germination percentage of only 70%, compared to the control group where a percentage of 90% was obtained. Based on the results obtained, and taking into account the proven antimicrobial properties of lavandin oil, it can be stated that this oil, in the optimal concentration, can be considered as an ecofriendly fungicide in grain warehouses. Marjoram oil proved an inhibitory effect regarding the germination of maize seeds, for all tested concentrations.

DownloadTHE DESIGN OF MECHANIZATION TECHNOLOGY FOR ALFALFA CULTURE IN THE GOTHATEA HUNEDOARA AREA pag. 248-256
G. VĂCĂRESCU, F. MLADIN, Anișoara DUMA COPCEA, Casiana MIHUȚThe mechanization of fodder production is of major importance for agricultural production in general and for the field of animal husbandry in particular. Among the mechanized works for the production of fodder, harvesting works occupy a special place, both due to the role that fodder plays in animal nutrition, as well as due to the particularities related to quality. Harvesting must be done at the optimal time and in the shortest possible time, in order to maintain the quality of the fodder and keep the losses at a low level. Obtaining high-quality harvests, at the lowest possible costs, can only be achieved through the application of specific, perfected technologies, which allow a superior utilization of both natural resources and inputs. The main objective in harvesting, preparing and preserving alfalfa in the form of hay is to create a final product with a food value as close as possible to the initial green fodder. The quantity and quality of hay obtained from alfalfa depends to a large extent on a number of factors, namely: - the production and initial floristic composition of the fodder (when mowing); - harvest season (harvest phenophase); - duration of the hay harvesting and preparation period; - the method of harvesting, preparing and preserving hay; - the quality and degree of mechanized execution of the harvesting and preparation of fodder in the form of hay.

DownloadSTUDIES ON THE TECHNOLOGY FOR THE EXECUTION OF A PLASTIC INJECTION MOLD pag. 257-263
G. VĂCĂRESCU, F. MLADIN, Anișoara DUMA COPCEA, Casiana MIHUȚThe mold is the mechanical subassembly that has the role of giving a certain shape to a plastic material with well-determined dimensions. The design and correct execution of injection molds conditions the achievement of high yields of injection processing. Molds for injection of thermoplastic materials are basically composed of two main parts: half mold from the injection nozzle side and half mold from the throwing side. The mold is fixed on the clamping plates of an injection machine. The majority of molds work by injecting the plastic material through a hole with the axis perpendicular to the plane to be separated. In the case of special injections (two-color or three-color injection), the injection is made both perpendicular to the plane to be separated and in the plane to be separated. In the construction of molds, thanks to the infusion of new technologies, optimization is constantly used. An example of this is NC milling after 5 axes. In addition to the reduced processing time of a mold, this also results in higher precision. Compared to NC milling after 3 axes, the processing after 5 axes of irregularly shaped surfaces is done with a smaller number of milling passes, with a better quality of the surfaces. The NC programs for 5 axes claim, thanks to the complex device, a large volume of calculation, at the corresponding processing speed. This can only be solved for the masses with the help of large computers. Complicated and long milling programs can be run with the help of these computers even during the night.

J.-Z. VERES, Paula BULZ, Silvana SPOREA, Diana PURICE, Ana Maria VIRTEIU, Ioana GROZEARapeseed is a profitable crop with economic and energy efficiency and perhaps the best melliferous plant. Besides the advantages, due to the yellow color of the inflorescence, it attracts a large number of insects, many of which are harmful and destroy the plant's organs. Through the present paper, we set out to see what is the range of species of harmful insects found in autumn in several localities in western Romania. The observations were made in the period 2020-2023, in autumn and spring (after sowing, during flowering and silique formation). The results showed the presence of 17 species of different systematic orders, observed in all active and inactive stages (adults, eggs, larvae and/or pupae). The most frequent species were: Phyllotreta nemorum, Phyllotreta atra, Meligethes aeneus, Athalia rosae, Myzus persicae, Ceutorhynchus assimilis, Ceutorhynchus napi, Autographa gamma, Plutella xylostella and Delia radicum, with limits of 3-6 (20/aphid) individuals active, adults or larvae/m2. Besides these, other species with a medium or low frequency (0.5-5 active individuals/m2) were also observed: Helicoverpa armigera, Pieris brassicae, Mamestra brassicae, Eurydema ornata, Ceutorhynchus pallidactylus, Agriotes spp. and Dasineura brassicae. In conclusion, rapeseed attracts many pests, many of them causing damage with significant production losses in the absence of effective monitoring and control strategies.

Ana – Maria VÎRTEIU1*, Snejana DAMIANOV1, L. MOLNAR1, Ramona ȘTEF1, Ioana GROZEA1The gall midge is the only known dipteran herbivorous insect on oak trees (with the exception of occasional opportunistic pollen feeders). The quercus gall midge is very host specific, it develops on the turkey oak (Quercus cerris). In Romania, there are 4 species of gall midges associated with Quercus spp., and recently the species Janetia cerris has been found in the urban green landscape of Timisoara. The damage caused by this species manifests itself in the appearance of conical galls on the upper side of the leaves, up to 3 mm high and light green in colour. The larvae develop inside these galls. Our investigations were carried out during 2022 – 2023 in 4 observation points in parks and green urban spaces in the city of Timișoara. During our investigation we used the same collecting method at each sample points. We noted in the protocol the geographical characteristics of biotopes and the local abundance of species. The survey indicates a high infestation level with gall midges in all 4 observation points that exceeds 70% of all analyzed samples. The attack can be recognized by the galls that appear on the upper side of the leaf, which have a sharp appearance, are about 2 mm long and lack pubescence; while on the lower side of the leaf, the gall is prominent, up to 5 mm in diameter, with long, yellow-brown hairs. Photos with larvae, galls on leaves, identification keys and brief description for this species are presented in this paper.

Laura VORNICU1, T. H. RUS1, A. PISTOL1, Ramona ȘTEF1*, A. CĂRĂBEȚ1*In the last 30 years, the area occupied by pearorchards, in Romania, is decreasing from 9974 ha to 4827.05 ha. Favorable conditions for pear cultivation can be found in 14 counties. Orchards are annually infested with weeds that compete with fruit trees for nutrients, space, water, light and reduce growth, vigor, flowering, production and fruit quality. Herbicides are an effective, easy and relatively cheap method of weed control. The effectiveness of herbicides against weeds is different for each species. The aim of this study was to reduce populations of Lamium purpureum and Ranunculus repens by using MCPA and Fluroxypyr-methyl. The testing of herbicides against the two weed species (Ranunculus repens and Lamium purpureum, was carried out in the Orchards Experimental Research Station - Lugoj Herindești (Timiș county). The experimental field included 5 variants: three treated with the hormonal herbicide MCPA 50% DMA (0.9 l/ha, 1.2 l/ha, 1.5 l/ha), one in which the herbicide Cerlit was applied (1.0 l/ha) and a control untreated variant. These herbicides were applied post-emergence (21.04.2022). The impact of MCPA and fluroxypyr, in the control of Ranunculus repens and Lamium purpureum species, was determined 10-38 days after application. 10 days after applying the treatments, the species Lamium purpureum was reduced by 70-75%, regarding the species Ranunculus repens it was observed that the product MCPA 50% DMA 1.5 l/ha managed to reduce the population in percentage of 80%. At 38 days after application, an increase in the effectiveness of herbicides in the control of segetal species was observed.
