DownloadRESULTS CONCERNING THE CONTENT OF HEAVY METALS IN LINDEN TREE AND MIXED FLOWERS HONEY, IN TIMIS COUNTY pag. 16-20
Oana Ciobanu, Hortensia RadulescuOne important point of the honey quality control is represented by the content of heavy metals. Because no specific Romanian Legislation regarding the accepted level of heavy metals in honey exists, EU Standards (European Honey Directive of the European Honey Commission) are used. The heavy metals residues could be originated from soil, plant or result from processing and environmental contamination. When the level of heavy metals in honey is monitories some other variables need to be considered such as weather, season or botanical origin of the flowers. Placing hives near roads with heavy car and trucks traffic, industrialized areas or unacceptable materials and equipment on the honey production circuit can represent other important sources for honey contamination with heavy metals. The purpose of this study is to link specific variations of the heavy metal content in Linden Tree and Mixed Flowers honey with the location of the beehives mainly from polluted areas and unpolluted ones in Timiş County. The studied locations are: Timişoara, Timişoara- near a national road, Chevereşu Mare and Sacoşu Mare. The main aim of the research was to determinate the content of heavy metals such as chromium, nikel, zinc, cooper, manganese, cadmium and iron in Linden Tree and Mixed Flowers honey samples collected directly from bee colonies. The sample analysis have followed standard methods for detecting heavy metals approved by STAS 784/2-2009 from Romania, using atomic absorption spectrophotometry (AAS).The results showed that the heavy metal content altered and depended on the floral sources of the honey variety and the beehives location. The highest lead content was found in Linden Tree honey, especially when the hives were located in places with heavy car traffic. The highest chromium content was established for the Mixed Flowers honey samples, content which increased for Linden Tree honey samples collected from hives placed near a national road. The highest level of iron, was measured for the Mixed Flowers honey samples, content which increased for Linden Tree honey samples collected from hives placed near a national road. An important cadmium and zinc level was measured in the Linden Tree honey samples. Placing the beehives near a polluted area increased the content of cadmium and zinc for both varieties of honey.

DownloadRISK EVALUATION OF THE FRUITS GRAY MOLD (BOTRYTIS CINEREA) BY FUNGUS PRESENCE ON WILDE RASPBERRY (RUBUS IDAEUS) pag. 21-25
Ciui (Mot) Cerasela, Borcean AdrianLike other areas in high hill areas, where traditional agricultural crops do not work, there is a possibility of focusing on plants that are highly adapted to the area and can bring satisfactory economic results. An example of such plants is raspberry, which could be easy adapted on areas like those found in the valleys of the main rivers in Caraş Severin County. One of the most important conditions for the success of such a culture is to have previously the knowledge of the potential technological problems which could impede the development of plants and the yield quantity and quality. One of these problems, which is very difficult to avoid, is the pathogens presence on raspberry plants from the spontaneous flora of these areas because in favorable conditions these pathogens could produce significant yield loses. Present paper contain data about evaluation of a well-known disease such as the gray rot of fruit produced by the Botrytis cinerea on raspberry plants from spontaneous flora. These pathogen produce random attacks on a few Rosaceae species such as Rubus sp., Fragaria vesca and Rosa canina. This fact leads to a high probability of pathogen disamination from the spontaneous flora natural reserve to any other raspberry culture, blackberry culture or even rose culture from the reference area. The area where observations were made is located in the middle basin of the Nera River, a well-known area for the high diversity of flora species, including species from Rosaceae genus. All data were collected during years 2016 and 2017 from raspberry populations (Rubus idaeus), large enough to be representative for this area and for statistical computation. Regarding to methodology, the main steps were: first step to identify pathogens, the second step was to record primary data of the pathogen attack frequency and intensity and the last step was the statistical evaluation of field data. The results confirmed a relatively constant presence of Botrytis cinerea fungus in raspberry in the middle basin of the Nera River.

s.l. dr. L. DANCEA, s.l. dr. I. GAICA, s.l. dr. V. MAZĂRERural development is considered, in E.U., as the basic point of the Agricultural Community Policy, particularly from the point of view of labor occupancy. Thus, they aim at the implementation of an integrated policy of sustainable rural development that allows for the valorisation of all types of potential in rural areas. The analysis of agro-tourism concept shows that it is a complex entity. Therefore, to know this concept one should decompose and explain its component parts centring on rural household activities, agro-tourism ones. Agro-tourism means evaluation of natural landscape, lodging offers and services provided by rural households and agro-tourism farms with the aim of getting an income. Agro-tourist households get basic incomes from agricultural activities, while part of the incomes are from agro-tourist services. The coordinates of sustainable rural development should start from a triple analysis - economic, social, and ecological. Any action has its impact, therefore, it should define sustainable development strategies and policies.

DownloadMECHANISATION TECHNOLOGY FOR THE HARVESTING OF GRAIN MAIZE WITH A SELF-PROPELLED COMBINE pag. 45-50
Duma Copcea Anișoara, Ilea R. Popa D. Sîrbu CorinaSelf-propelled combines for the harvesting of grain maize are made up of two main sub-ensembles: maize cob cropper and maize stem thrasher. The maize cob cropper detaches the maize cobs from the stems, carries the leafless maize cobs to the thrasher and chops the stems. Chopped stems can be recovered in a mean of transportation (tow) or they can be spread over the soil to be later incorporated into the soil. The thrasher thrashes the maize cobs, separates the grains from impurities, and carries the grains to the bunker. Scientific organisation of harvesting grain maize can result in shortening the harvesting period and in increasing labour productivity. To reach all these objectives and to rationally exploit the combines, we need to take such organisational measures as preparing the crop for harvesting, choosing the way combines move in the field, ensuring transportation means, etc. Preparing the field for harvesting starts with identifying ripening state, continues with marking the places with risk for the combines and establishing the access routes for the transportation means, and it ends with identifying fire guard spots. Self-propelled combines enter the plot without opening roads previously because the working width is larger than the thrasher width (it is a T working flow). First, we harvest the ends of the plot (that were sowed transversally), to ensure turning areas for the combines and to allow the access of the means of transportation and of other means necessary for harvesting. Harvesting maize grains with self-propelled combines is done with low losses (grain moisture below 20%). Analysing exploitation and economic indices, we can draw the following conclusions: the self-propelled combine CASE-IH 7088 + CS-8 harvests maize from eight rows over a width of 5.6 m. The combine is equipped with a Diesel engine of 325 HP and it has an hourly productivity of 24 t/h with a feeding flow of the thrashing device of 18 kg/s. For a production of 6 t/ha, fuel consumption reaches 11.2 l/ha (1.0 l/t) and total expenses upon harvesting grain maize reach 79.5 RON/ha, i.e. 13.3 RON/t. To obtain high yields per area unit with low expenses, we need to strictly observe cultivation technologies and use as complex as possible aggregates with the highest efficiency possible.

DownloadWHICH ARE THE MOST COMMON NON-WOOD FOREST PRODUCTS IN TIMIȘ COUNTY? pag. 51-56
Cristian Mihai Enescu, Lucian DincaThanks to its high diversity as regards the forest composition and structure, Romania has a great potential for harvesting several categories of wood and non-wood forests products (NWFPs). The aim of this research was to highlight the most representative NWFPs in the case of Timiș County. Four categories of NWFPs (i.e. Mushrooms, Tree products, Understory plants and Animal origin) and nineteen criteria proposed within the FP1203 COST Action European non-wood forest products network were taken into account. An Analytic Hierarchy Process (AHP) was used in order to evaluate both qualitative and quantitative criteria and to assess the performance of selected alternatives (i.e. NWFPs) by means of pairwise comparisons. The analyses were carried out using the Expert Choice Desktop software package. Penny bun and European hare were the most representatives non-wood forest products, when all the 19 selected criteria received an equal importance. In the view of switching the focus from wood to non-wood forest products harvesting, the forest managers should take also into consideration this kind of analyses in order to assess the potential of certain products in a particular scenario.

DownloadBASIC ROMANIAN AGRICULTURAL TERMS AND THEIR GERMAN EQUIVALENTS pag. 62-70
Groszler Astrid-SimoneThis paper continues our research regarding basic agricultural terms in the context of English for Specific Purposes, extending it to the area of German for Specific Purposes. It is true that, nowadays, the language of Science is English, and scientists all around the world need to be able not only to use the language in generic contexts and everyday situations, but also need to master the English technical terms relating to their field of study or research. However, for the European context in general and the Romanian one in particular, the importance of the German language has reached a peak not encountered 20 years ago, for instance. This new importance is rendered not only by the height of political importance German has achieved, given its standing within the European Union, but also by its economic importance as a partner in commerce as well as agriculture. As mentioned in our former research, agriculture has been established as an issue of utmost importance nowadays. German investors in the field of Agriculture make their presence felt in various countries, but, for the Romanian economy, they are a well-known and accepted reality. Therefore, during the last five years students attending the foreign language courses at faculties with an agricultural profile, have increasingly turned towards the study of German. The present paper offers a glossary of basic Romanian terms employed in agriculture and their German equivalents. Alongside researchers and academic staff, this paper targets students as well, on all levels - Bachelor, Master and Doctoral studies, since they are most likely to come into contact with specific German vocabulary either in their bibliographical studies, or through scholarships and internships. Moreover, we try to explain the reasons behind difficulties in translation and indicate reliable sources which will help researchers and students in their further contact with GSP (German for Special Purposes).

Factor A included untreated control and 4 antigraminaceous herbicides – Axial 050 EC (pinoxaden) - 900 ml/ha, Topic 080 EC (clodinafop) - 450 ml/ha, Traxos 045 EC (pinoxaden + clodinafop) – 1.20 l/ha and Scorpio super 7.5 EB (fenoxaprop-ethyl) – 1 l/ha. Factor В included untreated control and 4 antibroadleaved herbicides – Biathlon 4 D (tritosulfuron + florasulam) – 55 g/ha, Lintur 70 WG (triasulfuron + dicamba) – 150 g/ha, Granstar super 50 SG (tribenuron-methyl + tiphensulfuron-methyl) – 40 g/ha and Secator OD (amidosulfuron + iodosulfuron) – 100 ml/ha. All of antigraminaceous herbicides, antibroadleaved herbicides and their tank mixtures were treated in tillering stage of the durum wheat. Herbicide tank mixtures Scorpio super + Lintur and Traxos + Granstar super do not proven increase germination energy of the durum wheat seeds. Laboratory seed germination do not prove increased by combination of antigraminaceous herbicide Scorpio super with antibroadleaved herbicide Lintur only. Length of coleoptile is decreased by herbicide tank mixtures Scorpio super + Lintur and Traxos + Granstar super. Herbicide tank mixture Scorpio super + Lintur decreases lengths of primary roots and also increases waste grain quantity. Herbicide tank mixture Traxos + Secator lead to obtaining of the highest grain yield. High yields of durum wheat grain also are obtained by herbicide tank mixtures Traxos + Biathlon and Axial + Biathlon.

Grozi DELCHEV, Teodora BARAKOVAThe research was conducted during 2015 - 2017 on pellic vertisol soil type. Under investigation was Bulgarian winter forage pea cultivar Mir (Pisum sativum var. arvense). Factor A included untreated control and 2 soil-applied herbicides – Dual gold 960 EC, Stomp aqua. Factor B included untreated control, 5 foliar-applied herbicides – Basagran 480 CL, Pulsar 40, Korum, Zencor 70 WG, Maton 600 EK and 2 herbicide tank mixtures – Zencor 70 + Targa super 5 EC, Maton 600 EK + Targa super 5 EC. Soil-applied herbicides were treated during the period after sowing before emergence. Foliar-applied herbicides were treated during 2 - 3 real leaf stage of the pea. Foliar-applied herbicides Pulsar and Korum destroy completely all annual and perennial broadleaved and graminaceous weeds and self-sown plants in winter forage pea crops. Combinations of soil-applied herbicides Dual gold and Stomp aqua with foliar-applied herbicides Basagran, Pulsar, Korum, Zencor and Maton, as well as with herbicide tank mixtures Zencor + Targa super and Maton + Targa super exhibit an additive effect on herbicidal efficacy. Treatment with foliar-applied herbicide Maton leads to high phytotoxicity in pea – rate 3 according to the scale of EWRS. Herbicide tank-mixture Maton + Targa super leads to even higher phytotoxicity in pea – rate 5 according to the scale of EWRS. Foliar-applied herbicide Zencor and herbicide tank-mixture Zencor + Targa super also leads to phytotoxicity in pea – rate 2 according to the scale of EWRS. The highest yields of winter forage pea seeds are obtained by treatment with foliar-applied herbicide Korum after soil-applied herbicides Stomp aqua and Dual gold. High yields are obtained also by treatment with foliar-applied herbicide Pulsar after soil-applied herbicides Stomp aqua and Dual gold, as well as by foliar treatment with herbicide tank-mixture Zencor + Targa super after soil-applied herbicides Stomp aqua and Dual gold.

Iasmina IOSIM*, Gabriela POPESCUAbstract: Cultural tourism, in general, and religious tourism or faith tourism, in particular, has increased its share of domestic tourism in Romania in the last decades, and so have tourism TV commercials, tourism guides, tourism flyers, etc. The Romanians are Orthodox Christians, and using Turkish religious terms sometimes poses true problems. Fifty-five Romanian words of Turkish origin in the language of religion, words that have enriched our language through borrowing, composition, derivation and semantic change, are analysed from a morphological perspective (borrowings, compounds, derivatives, and semantically-evolved words). For each category of Turkish religious terms, usage restriction are identified, such as Colloquial, Derogatory, Familiar, Figurative, Historical, Jokingly, Literary, Obsolescent, Popular, Rare, Regional, and Slang. The classification of the religion-related Turkish borrowings presented in this paper will help tourism guide authors, TV commercial editors, trained tour guides, etc. use Romanian religious vocabulary properly taking into account the fact that direct contact with the Turkish language ended 150 year ago.

Péter JAKAB-Nóra MASA-Ágnes JUSZTIN-Anita BARANYI-István KRISTÓ-Margit SZÉL HódinéWe examined the influence of different fertilizer doses on the yield components, yield and quality of winter wheat on meadow soil in 2016-2017 years in Hódmezővásárhely. The experiment was carried out on the area of SZTE Tangazdaság Ltd. in three replications. Six fertilizer steps were applied besides the control: N80PK30, N100PK30, N130PK30, N150PK30, N170PK0, N170PK50 kg/ha active ingredients. The year 2016-2017 was unfavourable for winter wheat production. The amount of precipitation in the vegetative period of winter wheat was lower by 80.2 mm than the average. The obtained data were processed by single factor variant analysis. The yield components, yield, and quality parameters reached the highest value in N130PK30 treatment. The fertilization significantly increased the yield and number of spike. The thousand seed weight, Zeleny number and crude protein content of grain did not changed statistically justified compared non fertilized treatment. We can conclude, that, the N130PK30 kg/ha fertilizer dose was the most favourable concerning the yield components, yield and quality parameters of the examined winter wheat variety.

Hristofor KIRCHEV, Angelina MUHOVAA field experiment was set in the period 2014-2017 on the experimental field of the Research Institute of Field Crops of the Agricultural Academy, Chirpan. Three triticale varieties were used – the standard Colorit, and other two varieties created at Dobrudja Agricultural Institute – Gen. Toshevo, Bulgaria: Boomerang and Respect. The experiment consisted of a randomized complete block design after two predecessors – sunflower and durum wheat with four replication and plots of 10 m2 planted at a sowing rate of 550 viable seeds m−2. To achieve the aim of the study, during the vegetation of the triticale, fresh plants were taken by stages as follows: Tillering – leaves; Spike emergence – leaves, stems, spikes; Maturity – straw (leaves+stems), spikes, grains, glumes. After the two predecessors in the phase of spike emergence, the stems are the largest share of the plant, followed by the leaves and the spikes. However, the stems have a larger share after sunflower, and the share of leaves and spikes is close to the two predecessors. Although the relative share of the spikes is close after the two precursors, in the maturity phase, the relative share of the grain after durum wheat is 6.3% less than after sunflower, and the share of the glumes is 17.4% more.

DownloadTHE POTENTIAL IMPACT OF ECOLOGICAL AND GEOGRAPHICAL PARAMETERS ON THE SPREAD OF THE INVASIVE PEST NEZARA VIRIDULA pag. 107-113
Viorela Corina MARCU, Ioana GROZEAThe species Nezara viridula (L.) or green stink bug is one of the most recent non-autochthonous species that invaded agroecosystems in our country. The lack of natural enemies makes this insect rapidly spreading from the locality to the locality and from the geographic area to the other. It is not known exactly what causes enlargement to geographically or ecologically different areas. Globally, the insect is present both in warm and temperate areas. At Europe level it is found in almost all geographic points except the northern point. The observations of this scientific paper have been made in the southwest of Romania, more precisely at the level of the Caras-Severin County, which has a great variety of relief forms, from the plain to the mountains (from 168 m to 1000 m). The effective or size of the insect population at a given time, such as spatial distribution, has been the main parameters analyzed in terms of temperature and humidity but also geographical altitude. The observation period was in June-October of 2016 and 2017. Because they are large insects, trapping them with pheromone or colored traps is not conclusive and rather quantification by direct observations on the preferred plants (tomatoes, cucumbers, beans). To analyze population size and distribution in 8 different areas, 10 samples (one monthly sample/area) were processed. Correlations between environmental factors (temperature, humidity) have shown that high temperatures and low humidity favor activity and insect movement. The great presence of the species was mainly observed in areas with lower altitude of the county and less or not in high altitude areas, respectively at values ranging from 168 to 300 m.

DownloadATMOSPHERIC FACTORS USED IN THE CHARACTERIZATION OF SOIL RESOURCES pag. 114-120
Mihuț Casiana, Niță L.D.The paper presents the influence of atmospheric factors in the formation, evolution and utilization of soil resources. Of the atmospheric factors, with a major involvement in the formation of soil resources in Arad County, but not least, the greatest importance is the light, the average annual temperature, both the atmospheric and the soil level, the average annual rainfall. The direct or limited conditioning of these factors, the soils and, implicitly, the production obtained due to these atmospheric factors makes them have a particular importance and a role in the growth and development of plants, with direct involvement in the harvested crops. The studies were conducted over a three-year period (2015-2017). The studied area was Arad County. Within the area, the areas were chosen taking into account the type of soil, altitude, slope, exhibition and groundwater level. Annual averages of temperatures, rainfall and light intensity were calculated both as annual averages and monthly averages of the vegetation period, respectively in April-October. The results obtained from the calculations revealed that the major importance in the manifestation of each climatic character is determined by the geographical position, the slope of the terrain and the soil texture. Studies by other researchers have shown that variations in time and space require in-depth microclimate research, characteristics specific to each portion of the wounded territories. On the other hand, it is necessary to determine the sizes specific to each of the climatic properties and then to develop mathematical and regression curve expressions. In order to give faithful account of the influence of the water resource, a series of mathematical models have been tried over the years that only partially met the needs. A generalized synthetic index, more relevant to the possibility of plant photosynthesis, resulted from the multiplication of annual average temperatures (or other thermal resource ratios) with annual average precipitation (hydrothermal index) (D. Teaci - 1976).

DownloadNON-WOOD FOREST PRODUCTS FROM CLUJ COUNTY pag. 121-126
RALUCA-ELENA ENESCU, EMILIA VECHIU, DIANA VASILEFrom the oldest times, the forest has been an important source of both wood and non-wood products for all population categories, the life of some communities even depending on this source. Besides wood products offered by forests, the most popular categories of non-wood products are mushrooms, forest fruits, medicinal plants and wild species. Romania, due to the high variety of forests and of the site condition, has an enormous potential of the categories of non-wood products mentioned above. The aim of this paper is to study the non-wood forest products (NWFP) from Cluj county and to highlight the most important products from this county. Thus, eight type of non-wood forest products were selected from four categories: mushrooms, tree products, understory plants and animal origin products. The analysis of these products was made after a set of 19 criteria to determine the importance of each. After the analyses the most important non-wood forest products from Cluj county were that of animal origin and the less important was fruits from Crataegus sp.

Veta Nistor 1, Cristian Savin2, Magdalena Tenciu1, Elena Eugenia Mocanu1, Elena Jecu1 ,Valentin Ovidiu Eșanu1Summary Water, nutrients, used farmland zone, and energy are the most important aspects of the ecological sustainability of aquaculture farms. With regard to water, both necessary quantity and quality are important. An equally important goal in all systems is to reduce the amount of water needed in order not to put additional pressure on the natural ecosystem. An equally important objective is to reduce waste water and optimize treatment discharges because, in most cases, aquaculture discharges contain many nutrients that could contaminate natural systems. Traditional cyprinids fishponds only need water to replace the evaporated or infiltrated one; leakage is reduced until harvest. Under these conditions the control of microscopic algae blooms is particularly important. Efficient use of the necessary nutrients is also essential for ecological sustainability. The first step is to reduce food losses through an advanced feed system and by selecting the right feed. Using polyculture technologies can increase the efficiency of nutrients due to various ecological niches of fish species. Thus, in the experiments necessary for the development of an eco-efficient fish species breeding technology, three experimental variants were applied, besides the witness one, to the application of conventional technology, and the use of the growth in polyculture of the Carp species, Silver carp and Bighead. During the vegetative period of 2016 and 2017, the dynamics and structure of phytoplankton and zooplankton were monitored in the four growth experimental pools. The results showed that the phytoplankton structure was dominated by chlorophylls and diatoms, which did not pose problems in terms of the algae bloom phenomenon, algal densities being small. In the semiintensive growth system practiced in pools and ponds, which has as a technological principle the intensification of production on the basis of stimulation of natural fishery production and supplementary feeding, the carp benefits from the stimulation of the zoobenthos development, the silver carp - consumption of the phytoplankton and the bighead - zooplankton consumption .

That is why the localizing and defining each land portion in the terrestrial space is of utmost importance in determining ecologic conditions, respectively the vocation of a certain land portion for certain agricultural or agri-forestry-pastoral uses. The purpose of the current research originates in the current scientific and practical preoccupations, more and more avid to accumulate knowledge regarding the physical, chemical and microbiologic characteristics of soils in relation with the local particularities of the natural frame for the land quality assessment, data which can be found in the pedologic studies carried out by territorial OSPA units. Through its geographic position and the relief terraced spacing with a general slope from east towards west, the studied territory determines a great diversity of ecologic conditions, generated by factor variability (cosmic-atmospheric and telluric-edaphic) which help establish an environment where plants can grow and deliver yields. The study refers to a 3693277 ha surface, of which 2430481 ha (65.81%), represent agricultural land, 16.61 % of Romania’s total agricultural surface of 14635520 ha (Order MADR 278/2011, Annex 1). The current paper’s importance and novelty consists in the necessity to protect the edaphic layer and the environment through: - accumulation of scientific data needed in order to underlie working technologies which should help preserve the edaphic layer and sustainably manage soil and water resources

ȘMULEAC, Loredana COPĂCEANThe main purpose of this study is the description of the main stages for thickening the geodetic network through satellite measurements in Bara village, Timis County. For geodetic network realization field measurements were taken and then, the ghatered data were proccessed. The measurements were done using the ‚static’ method with 3 double frequency Leica 1200 series receivers L1/L2, in all the 5 settlements of the county: Bara, Lapusnic, Dobresti, Radmanesti and Spata, having as refferece points the GPS national geodetic network: Timisoara, Arad and Faget. For choosing the points that will thickening the geodetic network several criterias were taken into account. That’s why the first stage was to explore the terrain. After this first stage, 20 concrete landmarks were materialized manually after the current rules. This 20 concrete landmarks were equaly distributed in the settlements, 4 in each settlement, 2 at the enterence of the intravilan and 2 at the exit of the intravilan. The next stage was thickening of the geodetic network with other 55 feno landmarks placed in the intravilan of the settlements, usualy at the intersection of the streets, with visibility between them. After materialization of all landmarks, a GPS measurement campaign was made. To this measurements several parameters were taken into account, stationary time at each landmark being the most important. After this static measurements were done, RINNEX data were bought from Cadastral Office and Real Estate Advertising office from Timisoara, Arad and Faget. This RINNEX data were used for processing the raw data resulted from all the landmarks measurements which were post processed using Leica Geo Office software. After the coordinates for the 20 concrete landmarks were obtained through post processing, the other 55 landmarks were determined through ‘radio’ method. For verifying the correctness of the measurements, other 3 existing high order geodetic static signals were determined: Bucina signal, Odaia signal and Lapusnic signal.

DownloadTHE EFFECT OF PLANTING DENSITY ON THE YIELD OF SWEET POTATO [IPOMOEA BATATAS (L.) LAM.] IN SOUTH-EAST HUNGARY IN 2017 pag. 159-163
ADRIENN SZARVAS1 - EVELYN HERCZEG1 - LÁSZLÓ PAPP1 -TAMÁS MONOSTORI1Sweet potato also called batata (Ipomoea batatas (L.) Lam) is a perennial food crop of the morning glory family (Convolvulaceae) and widely cultivated as an annual crop in the warmer temperate climates. In Hungary, all new experimental data elucidating various factors of production technology are essential to improve efficiency, especially yield stability. Optimal plant density of sweet potato was shown to be highly dependent on the genotype in previous international studies. Thus, it is important to determine it for the genotypes grown under dosmetic conditions. Our field experiment was conducted at Domaszék, South-East Hungary, on moderately alkaline sandy soil of medium humus, very good phosphorous and good potassium content. The experimental setup was Randomized Complete block design with four repetitions, during the main cropping season of 2017 with the objective of determining the effect of variety and plant spacing on the productivity of the crop. The experiment consisted of four planting spacing setups (80 cm x 20 cm, 80 cm x 30 cm, 100 cm x 20 cm, 100 cm x 30 cm) with the Hungarian certified sweet potato variety ‘Ásotthalmi-12’. The planting was performed on 4th Juny 2017 without ridges and the crop was harvested on 15th October 2017. The highest yield per plant was obtained with the 100 cm x 30 cm setup (0,39 kg) that is the usually recommended density in technology guides. Then calculating the yield data for one hectare, we got different results. The highest storage root yield (13.93 t ha-1) was recorded with the density of 80 cm x 20 cm. Increasing plant density from 3.33 plants m-2 (100 cm x 30 cm) to higher level of 6.25 plants m-2 (80 cm x 20 cm) increased the production of total storage root yield from 13.16 t ha-1 to 13.93 t ha-1. In conclusion, the results of the study have revealed that the highest plant density of 6.25 plants m-2 (80 cm x 20 cm) – despite decreasing the yield per plant - resulted in the production of the highest storage root yields per hectar.

DownloadANALYSIS OF THE DEGREE OF PHENOTYPIC AND GENETIC DIVERSITY AMONG MAIZE INBRED LINES DERIVED FROM THE SAME HYBRID pag. 164-177
Andrei VARGA, Voichița HAȘ, Roxana CALUGAR, Ana COPANDEAN, Ioan ROTARThe paper aims to appreciate the degree of relationship / differentiation of lines created from a single source of original material. Relatively limited research has been done with related inbred lines (Musteață and Mistreţ, 2002), which at the present stage predominates in the maize improvement programs. Differentiating the sister lines, made from a single source of source material and related lines from various sources with common genitors, allows for their identity to be identified, a necessary element in the selection and hybridization process. Differentiating the sister lines, made from a single source of original material and related lines originating from various sources with common genitors, allows the determination of their identity, a necessary element in the selection and hybridization process. Determination of the degree of similarity was done by various methods:the pedigreeof the lines, morphological characters, heterosis (production and production elements) and general combining ability. There were studied 7 inbred lines of common origin, among which crosses of type (4) p (p-1) / 2 dialel were made. Both parental lines and crosses were studied at SCDA Turda, within the maize amelioration laboratory in the year 2016. At the parental lines, 22 phenotypic characters were studied after the UPOV system. From the heterosis calculation made from the crossing of the 7 lines (of common origin), heterosis values> 90% result for: grain production, ear weight, grain weight, insertion height and foliar surface. The purpose of this paper is to assess the degree of similarity of the lines created from a single source of the original material, which has allowed the establishment of their identity, a necessary element in the selection and hybridization process.

DownloadSTUDY ON THE EFFICACY OF SOME HERBICIDES FOR WEED CONTROLIN IN LAVANDER FIELD pag. 178-185
Zhelyazkov, I., V.Delibaltova, T. KrastevThe experimental study was carried out during the period 2013-2014 in a young lavender field on a soil type of leached chernozem in Tsarichino village, Balchik municipality, Dobrich region - Bulgaria. The test was performed by means of a block method with four repetitions; experimental field area - 15 m2 . The experience includes six variants: 1) Economic control - untreated, with three hand hoops; 2) Devinol 4F – 4l/ ha; 3) Stomp New 330 SEC -/ 4l/ha; 4) Pledge 50 WP -0,08 kg/ha; 5) Goals 2E + Dual Gold 960 EC - 1 + 1,5 l / ha; 6) Merlin Flex 480 CK – 0,42 l/ha. The aim of the present study was to develop an efficient weed control scheme in a young lavender field, depending on the species composition and density. The analysis of the results showed; the applied herbicides exhibit good efficacy against the annual broad-leaved weeds and a weaker control of the perennial weeds. The best control of the annual and perennial weeds in a young lavender field was reported in the variants with the herbicides Devrinol 4F applied at the rate of 4l/ha and Pledge 50 WP at the rate of 80g/ha. The applied soil herbicides did not show a negative effect on the annual growth of the lavender plants.

DownloadTHE HERBARIUM – A DATA SOURCE FOR ALLIUM GENUS SPECIES pag. 186-193
Scărlătescu Virgil, Vasile Diana, Voiculescu IonAllium is an extremely diversified genus that encompasses more than 750 species almost exclusively distributed in the North hemisphere (Mediterranean Europe, Asia, North America, South America and sub-Saharan Africa). The Allium genus includes some species that are economically valuable and cultivated worldwide, such as the common onion, garlic, scallion or chive. Other species have important medicinal properties or are used in horticulture. The purpose of this paper is to inventory the Allium genus species present in the Al. Beldie Herbarium from INCDS ”Marin Drăcea” Bucharest and describe some of them. The Herbarium host 111 plates that contain 56 Allium genus species. Most plates belong to Allium schoenoprasum L, Allium oleraceum L. and Allium ursinum L. and the most Allium genus species were gathered in 1932 and 1942. A large number of plates are signed by Al. Beldie, while others belong to S. Pașcovski, Al. Borza, C. C.Georgescu and were gathered from Italy (Naples, Sicily), Bulgaria, Alps or Pyrenees and from Romania from Bucegi Mountains (most of them), Băile Herculane, Iași, Tulcea. The herbarium offers a unique perspective for the Allium genus species in regard with their location-temporal dynamic. The information can be used as a starting point for comparing distribution changes from the past and the future.

DownloadTHE IMPORTANCE OF THE VACCINIUM SPECIES COLLECTION pag. 194-201
Virgil Scărlătescu, Diana Vasile, Lucian DincăGenus Vaccinium (Ericaceae), subfamily Vaccinioideae, tribe Vaccinieae comprises 36 sections and, reach more than 450 species. Most known species are, in Europa: V. mirtillus, named “Heildelbeere”, “Blaubeere etc. which is commonly used as medicinal plant and in potted fruit. The aim of this article is to describe some Vaccinium species that are collected in the Al Beldie Herbarium from INCDS Marin Drăcea Bucharest. The Herbarium host 149 plates with Allium genus species. Most plates belong to V. myrtillus, V. uliginosum and V. vitis-idaea. The oldest Vaccinium specimen was collected in 1850. The herbarium specimens were generally in good condition except for a smaller number of specimens which were damaged. The Herbarium Collection Al Beldie stored in INCDS Bucharest has an immense historical and museological importance. The Vaccinium genus in this collection is very diverse. The diversity of this material also pertains to areas and habitat types in which the material was collected. Considering the age of this herbarium material, it may be used for comparison with present-day conditions of flora in the same areas
