The market for oilseeds in Ukraine is a large segment of the general market foragricultural products. Mustard (Brassica junceaL) is an oilseed crop that canrestore the optimal ratio of crops in crop rotation and not reduce the rates ofeconomic activity. Ukraine is among the top ten world leaders in its cultivation.The warming trends observed over the last 30 years in the world and in Ukraine,allow growing of mustard throughout the country. Consequently, it becamenecessary to develop varietal technologies for growing mustard for specific soiland climatic conditions. The objective of this research was to develop cultivationtechnology for Brassica junceaL in the conditions of the north-eastern foreststeppeof Ukraine for the first time. We studied the influence of weather conditionson the peculiarities of growth, development, formation of biomass, photosyntheticactivity, productivity indices, yield, seed quality, oil production, depending on thevariety, sowing time, seeding rates and fertilizer for growing bluish mustard.According to research results, for the formation of 1.71-1.91 t/ha of bluish mustardseeds in the conditions of the north-eastern forest-steppe of Ukraine on typicalblack soil, the cultivation technology should include: use of seeds of modern highyieldingadapted varieties; start sowing at soil temperature of 4-5 o C at a depth of10 cm; the rate of fertilizer N30P30K30 (during pre-sowing cultivation) and seedingrates of the varieties Prima - 1.5 million pieces/ha, and Retro -2.0 millionpieces/ha.

The aim of the article is to establish the optimal sowing density of soybean plants depending on the maturity group of the variety to obtain consistently high yields. For this purpose, new varieties of soybeans Siverka, Medison and Sihaliia were taken for research, which differ not only in the duration of vegetation, but also in morphological characteristics. The object of the research is the process of forming soybean yield depending on the variety and standing density. The subject of the research is the varieties: early-ripening Siverka from the Institure of Agriculture of the National Academy of Agrarian Sciences of Ukraine (NAAS), year of registration - 2013, plant growth type - intermediate; middle-early Medison from Hyland seeds: it has been in the Register of the varieties of Ukraine from 2008; type of growth - indeterminate; middle-ripening Sihaliia fro Dunai Agro, which was brought in the Register of the varieties of Ukraine in 2014, type of growth - indeterminate; seeding rates of 600, 700 and 800 thousand per ha; soybean grain yield. The forerunner in the experiments was winter wheat. Soil preparation consisted of stubble peeling and fallow plowing. Before sowing cultivation with harrowing was conducted. Sowing was carried out at a time when the soil at thr depth of 10 cm warms up to 100C in the usual row manner with a row spacing of 15 cm to the depth of 4-5 cm. Crops care laid in carring out preemergence and two post-emergence harrowings. Studies have shown that soybean yields depended on the variety and density of plants. Thus, on average over the years of research, the yield in the variety Siverka varied from 2.01 t per ha at a density of 800 thousand pieces per ha and decreased as it thickened to 2.26 t per ha at a density of 600 thousand pieces per ha. In the Medison variety, the yield ranged from 2.18 t per ha at a density of 600 thousand units per ha to 2.41 t per ha at a density of 700 thousand units per ha. In the Sihaliia variety, the yield varied from 2.28 t per ha at a density of 600 thousand pieces per ha to 2.50 t per ha at a density of 800 thousand pieces per ha. The maximum yield for the years of research (2.09-2.39 t per ha) the variety of Siverka formed at a density of 600 thousand pieces per ha. In the Medison variety the highest yield (2.31-2.52 t per ha) was obtained at a standing density of 700 thousand pieces per ha. The yield of the Sihaliia variety depended to a greater extent on the weather and climatic conditions of the year. Thus, under drier conditions in 2017, the highest yield of the variety (2.44 t per ha) was formed at a density of 700 thousand pieces per ha. Under more favorable conditions, the highest yield was obtained at a density of 800 thousand pieces per ha - 2.51-2.69 t per ha. Depending on the weather and climatic conditions of the years of research, the highest yields of all varieties were obtained under favorable conditions in 2019 - 2.27-2.56 t per ha. Under drier and cooler conditions in 2017, the yield of all varieties was lower by 0.13-0.41 t per ha. Thus, in the conditions of the north-eastern part of the forest-steppe of Ukraine, in order to obtain a high soybean yield, it is necessary to take a differentiated approach to the choice of the optimal standing density depending on the maturity group of the variety. Optimal conditions for the formation of maximum productivity of early-ripening soybean variety Siverka were created in the agrophytocenosis at densities of 600 thousand per ha, for medium-early variety Medison - 700 thousand per ha, and for medium-ripening variety Sihaliia - 700-800 thousand pieces per ha.

Increasing production and improving the quality of garlic products is an important production problem. Under the conditions of the vertical zonality of the North Caucasus with varying agroecological conditions, the yield of this crop largely depends on the technology of cultivation and the level of its intensity. Important factors determining the yield and quality of garlic products are varieties adapted to these agro-climatic conditions, quality planting material, cultivation technology that meets the requirements of the crop and the agro-climatic conditions of the region. Currently, the potential productivity of the varieties used in the republic is realized only by 30-40 percent. This is due to the insufficient development of technologies for their cultivation, taking into account the specific environmental conditions of the region. In this regard, research aimed at studying the basic laws of the formation of yield and product quality varieties of garlic is a pressing issue.

Впервые в мире создана популяция зубров на территории 60 градусов северной широты. В новых климатических условиях разведения и сохранения зубров определены и проанализированы факторы существования вида на севере Европейской части РФ. Выявлены признаки, динамика численности, которые являются составной частью системы, предназначенной для управления биоразнообразием. Интродукция, являясь процессом введения в экосистему нехарактерных для нее видов, может усиливать изменения биоценозов как положительно, так и отрицательно. Насколько быстро и успешно проходит процесс адаптации заселенного вида, и усматривается его влияние на окружающую среду зависит дальнейшее существование зубров и в целом биоразнообразия. В статье обсуждаются вопросы взаимоотношения зубров с другими видами копытных и хозяйственной деятельностью человека, а также дальнейшим использованием зубров в сельскохозяйственном производстве. Пластичность зубров, выявление изменений и их анализ при вселении видов в новые условия обитания необходимы не только для определения развития или деградации биоценозов и в целом экосистемы, но и прогноза социально-экономических последствий интродукции как одного из методов сохранения редких и исчезающих видов фауны.For the first time in the world, a bison population has been created in an area of 60 degrees north latitude. In the new climatic conditions of breeding and preservation of bison, the factors of the species existence in the north of the European part of the Russian Federation are identified and analyzed. The signs, dynamics of abundance, which are an integral part of the system designed to manage biodiversity are identified, since the preservation of biological diversity on the planet is one of the main problems of our time. Introduction, being the process of introducing non-typical species into an ecosystem, can enhance changes in biocenoses, both positively and negatively. The question posing sounds especially when it comes to such a large hoofed animal as the European bison. How quickly and successfully the process of adaptation of the universe takes place and its environmental impact is seen depends on the continued existence of bison and biodiversity in general. The article discusses the relationship of bison with other types of ungulates and human activities, as well as the further use of bison in agricultural production. How these issues will be resolved positively depends on the future of these animals. Thus, the plasticity of bison, the identification of changes and their analysis, with the introduction of species into new habitat conditions is necessary not only to determine the development or degradation of biocenoses and the ecosystem as a whole, but also to predict the socio-economic consequences due to the introduction as one of the methods of preserving rare and endangered species of fauna.

According to statistic evaluation of the manifestation of signs of the economic suitability of state sort resources of 2019 registration potatoes when growing it in different agro-climatic conditions, a significant advantage of influence of the forest-steppe conditions was determined. Compared to Polesia the increase of yield rose for 4.1 t/ha or 18 % (НІР05 = 2.18, Ffact= 12.65 > F05 = 4.22) and the amount of trade potato for 22.72 ha or 20 % (Ffact = 58.87). There is also a tendency to increase the number of starch from unit of area for – 17 % and the total consumer properties for – 8 %.  However, there is a significant difference in the reduction of storability of products by 45 % and the lack of it’s resistance to macrosporiosis and late blight. It was proved that the yield of varieties for cultivation in the polesia zone by 25.7 % depended on the duration of the growing season (Ffact = 4.14 > F05  = 0.06). The relationship between yield and starch of potatoes in Polesia zone varieties  was determined – 23.6 % and in forest-steppe – 17.3 % and starch collection, respectively, 33.6 % and 28.0 %. The dependence of storability of potato which grew in the polesia zone and in forest-steppe from the amount of starch for 15 % was mathematically proved (Ffact = 2.11 > F05 = 0.17) і 11.3 % (Ffact = 1.52 > F05 = 0.24); the dependence of storability on the duration of the growing season in the Forest-Steppe conditions was confirmed(Ffact = 0.66 > F05  = 0.43). In addition, the 12 % of tasting grade of the Forest-Steppe varieties depended on the starch content amount (Ffact = 1.65 > F05 = 0.22). According to the results of the regression analysis, mathematical models have been developed to predict yields, culinary and consumer properties, and the storability of new potato varieties under different growing conditions. The project of a conveyor for the consumption of fresh product in summer  period with the involvement of varieties of early ripeness in the Forest-Steppe was presented: 80 days after planting – Sanibel, 90 days after planting – Medison, Paroli, 95 days after planting – Bazalia, Bernina, 100 days after planting – Donata, in the Polesia zone ‒ 80 days after planting – Sanibel, 90 days after planting – Paroli, 95 days after planting –Bazalia, 100 days after planting – Medison, Bernina, Donata. By distribution of varieties by predicted high content of phytonutrients there were bred varieties with red skin and creamy flesh – Bazalia and Sanibel, by high content with yellow flesh – Baltic Rosa and moderate content with white flesh – Oleksandrit, Fotynia, Ricarda. Introduction of new varieties with certain high adaptive potential of storability and content of bioactive compounds in potatoes will provide growth of potato production in the conditions of the northeast forest-steppe and increase its competitiveness in the domestic and foreign markets and will solve the problem of year-round consumption of fresh quality products.

Riassunto - Gli scopi di questa ricerca sono quelli di contribuire alla conoscenza della macrolepidotterofauna della Sicilia nord-orientale e di caratterizzare la comunità presente nella Riserva Naturale Orientata “Laghetti di Marinello”. Sono stati effettuati 23 campionamenti tra dicembre 2007 e dicembre 2008 col metodo della caccia al lume. Sono stati catturati 2.537 individui appartenenti a 160 specie, tra cui Chloroclystis v-ata e Laelia coenosa, segnalate per la prima volta in Sicilia; importanti anche le segnalazioni di Calamodes subscudularia, Mythimna languida e M. joannisi, specie piuttosto rare e localizzate. Le specie più abbondanti sono state: Eilema caniola, Eublemma viridula, Idaea filicata, Dysauxes famula e Idaea seriata, che da sole rappresentano il 42% di tutta la comunità, favorite dalla presenza delle rispettive piante nutrici e dall’elevato adattamento alle condizioni climatiche del sito. Il numero di specie e i valori degli indici di diversità indicano un basso livello di biodiversità ospitata, ma la fenologia, le analisi corologica e autoecologica delle specie, insieme ai confronti effettuati con altre faune, indicano una comunità ben caratterizzata e peculiare, diretta espressione delle condizioni abiotiche e biotiche della Riserva.Abstract - Macroheterocera of the Oriented Natural Reserve “Laghetti di Marinello” (north-eastern Sicily) (Lepidoptera: Heterocera). The aim of this research is to contribute to the knowledge of the fauna of macrolepidoptera of north-eastern Sicily and to describe the community present in the Oriented Natural Reserve “Laghetti di Marinello”. 23 samples were carried out from December 2007 to December 2008 using a white vertical sheet reflecting a light source. 2.537 specimens belonging to 160 species were captured. Chloroclystis v-ata and Laelia coenosa were reported for the first time in Sicily, Calamodes subscudularia, Mythimna languida and M. joannisi, very rare and localized species, were also reported. The most abundant species were: Eilema caniola, Eublemma viridula, Idaea filicata, Dysauxes famula and Idaea seriata, which represent the 42% of the whole community and are favoured by the presence of their feeding plants and by their high adaptability to the climatic conditions of the place. The number of species and the values of the diversity indices show a low level of biodiversity, but phenology, chorological and autoecological analysis of the species, with comparisons made with other faunae, show a well characterized and peculiar community, direct expression of the abiotic and biotic conditions of the Reserve.

A 3-year study was conducted to measure the effect of sowing time and seeding rate on the development and yield of wheat (Triticum aestivum L.) grown under high-yielding conditions in north-eastern Victoria. A range of wheat cultivars with different development responses, including 'winter' types, was used in 2 experiments in each season. High grain yields for dryland wheat were measured in the first 2 seasons (1985-86), and in 1985, near-optimal water use efficiencies (>18 kg/ha. mm effective rainfall) were obtained. In the third season (1987) grain yield was limited by adverse climatic conditions-in the me- and post-anthesis period. In each season, grain yield declined with delay in sowing time. In 1985 there was a loss of 200-250 kg grain/ha for each week's delay in sowing time. In 1987, yield loss with delayed sowing was 50-110 kg grain/ha. In each season, cultivars with late or midseason maturity development gave the highest mean yields, and the use of these maturity types allowed earlier sowing, in mid April. However, with late sowing of wheat there was a trend for early maturity types to give higher yields, and so the use of 2 wheat cultivars with distinct maturity development responses to climate is recommended. If only 1 wheat cultivar is to be used, then a late maturity type is recommended. Higher wheat yields were also obtained as spike density increased, as a result of higher seeding rates. Our data suggest that in the higher rainfall region of north-eastern Victoria, a spike density of about 500 spikes/m2 is required to optimise wheat yields.

Sunflower Crop

At the present stage, the model of leaf plant development is increasingly considered as the main element of genotypes adaptation to specific cultivation conditions, geographical area, etc. Under these conditions, the potential of the hybrid, the range of its adaptation to environmental conditions is determined by the level of interaction between the development of the assimilation apparatus and the generative organs. An urgent task aimed at improving the productivity of sunflower crop due to the use of genotypes adapted to the conditions of the north-eastern Forest-Steppe and Polyssya of Ukraine is to identify typical schemes of interaction of photosynthetic potential and parameters of plant productivity and crop yields. The studies were conducted in accordance with the program for the development of a variety model for the conditions of the north-eastern Forest-Steppe and Polyssya of Ukraine. Field experiments were carried out in 2016‒2019 at the Sumy National Agrarian University and the Institute of the Agriculture of North East of Ukraine. In the studies, 28‒56 hybrids of different originators were tested annually. Sunflower was cultivated according to the technology recommended for the area, with pre-harvesting density of 60 thousand plants / ha. Harvesting was done manually, from two central rows of a 4-rows plot. The results were processed using the Statistics package. The data on yield indices and values of leaf area coefficient (LAC) of crop for groups of varieties separated by the duration of growing season were analyzed. It was found that the increasing of leaf area was accompanied by an increasing of yield in case of comparing groups with dates of technological maturation until 20 August, 1 September and 10 September. In all cases, the maximum value of the leaf area index ranged from 3.12‒3.52 m2/m2. These dynamics of indicators indicated to the regulatory nature of the values of leaf area coefficient (LAC) of modern sunflower crop and the absence of genotypes (or conditions) capable of maintaining these values at the level of more than 3.3‒3.5 m2/m2. According to the analysis of correlation pleiades, the presence of several levels was found and the relative independence of the relationships between the group of parameters, determining the morphological structure of plants and the vertical structure of crop and the group of parameters, characterizing the content of chlorophyll and its concentration per unit area of leaf surface. In practical terms, the results of the analysis indicated the potential informative nature of the complex use of parameters characterizing the morpho-structure of plants, primarily the index of leaf area and the index of chlorophyll concentration per unit area. In order to isolate the typical schemes characteristic of different levels of adaptation to the conditions of the zone, data on 29 sunflower hybrids distributed in the region were clustered. The results of the analysis allowed to distinguish three significantly different algorithms for the realization of the vegetative and generative potential of sunflower hybrids in the area of the north-eastern Forest-Steppe of Ukraine. It has been established that one of the factors for successful realization of the generative potential of sunflower hybrids in the conditions of the zone is the ability to preserve and (in some cases) to improve the structure of relations between the dynamics and parameters of the plant leaf apparatus and the parameters of their generative development.
