The authors make a case that oat selection should have profound focus in the regions with profound contrasting weather conditions such as Western Siberia is. The adaptive variety has environmental plasticity and combines stable high productivity with grain quality. The researchers study a set of varieties of oats under the conditions of the southern forest-steppe zone of the Omsk region according to the parameters of environmental adaptability, estimated on the basis of protein concentration pro a unit of land. The experimental part of the work was carried out during 2013-2018 on the experimental fields of Omsk Research Agricultural Centre (Southern Forest Steppe, Omsk). The protein concentration in the oat grains was determined according to the Pleshkov’s method. On average, the protein concentration in chaffy oat and Hulless oat didn’t vary significantly and was equal to 408.8 and 407.4 kg/ha, respectively. Protein concentration standard of Tarsky 2, Uran, Fakel and Sibirskiy Gerkules varieties exceeded the average by 14.1-71.5 kg/ha. The authors estimated the following adaptability parameters: stress resistance (Ymin-Ymax) and compensatory capacity (Ymin+Ymax)/2 according to Rossielle, Hemblin method; ecological plasticity coefficient (O) – according to Baransky methodics; variation coefficient (V) and equation coefficient (B) – according to Armor; the level of variety stability - according to Nettevich method; coefficient of responsiveness to favorable conditions of cultivation (Kr) - by Zykin; environmental plasticity index (EPI) – by Gryaznov; coefficient of adaptability (CA) - by Zhivotkov. A comprehensive assessment of spring oats varieties, taking into account a smaller number of ranks, identified the varieties, most adapted to high protein concentration in the southern forest-steppe zone of the Omsk region: a standard chaffy variety Orion, Uran (total ranks were 37 and 36), as well as the standard of hulless oat group which is Sibirskiy golozernyy (total ranks are 72).

The article is devoted to the study of the influence of modern potato varieties of different ripeness on productivity indicators in the Western Forest-Steppe. Methods. Analysis, synthesis, generalization, field experiment. Results. The results of research showed that varietal characteristics influenced the elements of productivity of potato tubers, with the best productivity of potato varieties were Knyagynya, Myroslava and Solokha. It should also be noted that the productivity of varieties of different ripeness of potatoes depended on the weather and climatic conditions of the year. Conclusions. On average, over the years of research of 5 varieties, the average productivity of the bush was – 707 g. The highest productivity was shown by the variety Knyagynya – 924 g. It should be noted that the varieties Myroslava and Solokha also formed a high productivity from the bush: Myroslava – 762 g., Solokha – 702 g., respectively. Less productive varieties were Shchedryk – 597 g and Levada – 547 g. Analysis of weather and climatic conditions of 2019-2020 showed that the most favorable were the climatic conditions of 2019, the value of the trait this year averaged 794 g, less favorable conditions for the development of the analyzed indicator developed in 2020 – 620 g. The correlation coefficient between productivity and number of tubers from the bush was r = 0.8. It was also found that the differences in the average number of tubers from one bush between varieties was insignificant. The study of experimental varieties showed that the largest number of tubers from one bush in two years, formed in the variety Knyagynya – 10.4 pcs., variety Solokha – 8.4 pcs., and variety Levada – 8.0 pcs. On average, for two years of research, the average weight of tubers was at the level of – 86 g. Thus, the largest average weight of tubers was formed by Myroslava variety – 102 g, and Knyagynya variety – 91 g. In 2019, the weight of tubers varied from 69 g. in the variety Levada to 113 g. in the variety Myroslava; and in 2020 from 70 g. to 90 g., respectively. Thus, the most favorable for the formation of large tubers were the weather conditions in 2019, the average weight of tubers in this period was 95 g, in 2020 – 77 g. Thus, in the conditions of the Western Forest-Steppe of Ukraine on leached low-humus medium loam black soil the most productive varieties of potatoes are varieties Knyagynya, Myroslava and Solokha.

Abstract. This article presents the results of a long-term study of a set of oat varieties in the southern forest-steppe zone of the Omsk region. The estimation of parameters of ecological adaptability for protein collection per unit area is given. Purpose. Long-term study of a set of oats varieties in the conditions of the southern forest-steppe zone of the Omsk region according to environmental adaptability parameters calculated on the basis of “protein collection per hectare”. Methods. The research was conducted from 2013 to 2017 in the conditions of the southern forest-steppe of Omsk. A detailed analysis of the adaptability parameters is provided: the indicator “protein collection per hectare” according to Zykin, ecological plasticity index according to Eberhart and Rassel, stability factor according to Lewis, homeostaticity and selection the value of varieties according to Khangildin, relative stability and stability criterion according to Sobolev, intensity according to the method of Udachin. The final adaptability of varieties is estimated by the sum of the ranks obtained by each variety for the studied parameters. Results. The results of the research have shown that they are most adaptive in the southern forest-steppe zone Omsk region filmy varieties Orion, Uranus and Sibirskiy Gerkules (total ranks 34–44) and Sibirskiy golozernyy (total ranks 61). Scientific novelty lies in the study of 13 varieties of membranous and hulless groups of oats, recommended for cultivation in the Omsk region. The collection of protein per hectare is an integral parameter that takes into account two indicators: the actual yield of the variety and the content of crude protein in the grain. Therefore, studies on this indicator are not popular. For the first time, thanks to the adaptive characteristics, varieties are divided according to this characteristic into intensive and extensive. The grouping of varieties depending on the cultivation areas is also given.

Purpose. The aim of the research conducted during 2016-2019 was to determine the impact of technological methods on the indicators of corn grain quality to optimize the elements of growing technology depending on the directions of use in conditions of the Forest-Steppe natural zone of Ukraine. Methods – field, quantitative and weight, chemical, comparative and calculation, mathematical and statistical. Results. On the results of the research, dependences of formation of quality of grain on the content of protein, starch, fat in it and correlation dependencies between these indicators and yield of corn have been revealed. The best quality of grain of a forage and food direction is formed when applying high doses of mineral fertilizers, and for processing on bioethanol the optimal content of starch and protein is guaranteed at optimum and raised level of fertilizing. It was established that the content of protein, starch and fat had less effect on their yield from 1 hectare than the general yield level. The technologies of cultivation of different intensity as to their possible application for the production of grain of different directions of use with the given quality parameters, the yield of protein, starch, fat and bioethanol have been evaluated. Conclusions. The technology of corn growing with complex application of intensification elements in conditions of the Forest-Steppe zone, which includes introduction of N240P120K240 on the background of by-products of its predecessor, application of the soil and insurance herbicide, plant growth and micro-fertilizers is suitable for fodder and food purposes and ensured the yield of 12.1 t/ha of grain with protein content and yield – 10.56% and 1.28 t/ha, fat – 4.29% and 0.52 t/ha, starch – 71.27% and 8.62 t/ha. For processing on bioethanol effective is the technology of corn growing with the introduction of N180P120K180, by-products of the predecessor, soil herbicide and bio-stimulants, which provided a yield of 9.76 t/ha of grain with a starch content of 72.26% for the yield of 7.05 t/ha and yield of bioethanol at the level of 3982 l/ha.

he effect of sowing multiple-nutrient mineral fertilizerapplication on spring wheat crops of the Astrid variety on gray forest soils of the forest-steppe zone was found. The study of the weather conditions of the growing season showed that the total amount of precipitation during the growing season was significantly lower than the average annual -158 mm as compared to 220 mm of the normal. The monthly rainfalls sharply differed from long-term ones; this had a significant impact on the formation of yield and grain quality. The application of NPK fertilizer and ammoni-um-phosphate-sulfate at a rate of 100 kg ha and ammoni-um phosphate fertilizer at a rate of 50 kg ha increased the yield of spring wheat grain by 8-66%, and the gluten con-tent in the variant with ammonium phosphate fertilizer at the level of 26-31% ascompared to 28% in the control. The payback of 1 kg of the primary nutrient of the fertilizers by grain yield gain was the highest against the background of NPK fertilizer and ammonium-phosphate-sulfate -55.0 and 40.8 kg, respectively. The protein content in wheat grain for in all fertilization variants ranged within 13.1-15.2% as compared to 13.7% in the unfertilized variant. The thou-sand-kernel weight as a result of obtaining high gains in the variants of sowing application ranged within 31.1-38.3 g; TKW below the control was in the variants with ammonium phosphate fertilizer and ammonium-phosphate-sulfate -31.1 and 33.4 g. The grain-unit belonged to Class 3 (no less than 730). It has been found that it is agronomically efficient when cultivating soft spring wheat in a temperately moist zone, on more arid years, on gray forest soils, when sowing, to apply NPK fertilizer and ammonium-phosphate-sulfate at a rate of 100 kg ha.

It has been highlighted the data of researches as for the influence of natural and climatic zones of Ukraine on display of economically useful signs of the most numerous cattle in the country like Ukrainian black-spotted dairy breed. It was the grounds to assert the efficiency of resources use in those conditions to which they are most adapted and have genetically determined potential. It was found that cowsof lactation breeding herds in the Forest-steppe zone produced 7344 kg of milk, which is 242 kg and 1125 kg more than in the Steppe and Polissya regions due to significant variation of the characteristic within each climatic zone (Cv = 11.6– 27,5%). The Polissya zone, where the animals' yieldwere 5764 kg, while in other climates 6982–6992 kg, does not contribute to the high productivity of the first lactation cows. It is proved that the duration of the service period in cows of three natural and climatic zones of Ukraine varied from 106 days in Polissya to 126 days – Forest-steppe, but it did not agree with the output of calves per 100 cows, which in 81 Polissya amounted to 82 and Forest-steppe – 79. The heifers of the Steppe zone are inseminated with live weight of 391 kg at the age of 477 days, and the Forest-steppe and Polissya with slightly less 385 kg and 387 kg, respectively, at the age of 493 days and 517 days. There is no significant difference in live weight at the ages of 6, 12 and 18 months between heifers of different natural and climatic zones of Ukraine, but the degree of development of the trait after 6 months was slightly better in cattle of the Steppe zone. A positive correlation was found between milk yield of first lactation cows of all natural climatic zones and their live weight at 6, 12 and 18 months of age, as well as negative calf age at first insemination (-0.587 ... -0.810) with significant correlation from the cattle of the Steppe zone. A high correlation coefficient (+0.703) was found in cows between live weight of heifers at first insemination and first lactation in the Polissya region. Key words: natural and climatic zones, Ukrainian Black-and-White Dairy breed, cows, yield, lactation, live weight, reproductive ability indicators, selection traits.

Исследования проводились в лесостепи Восточной Сибири в 2018–2019 годах. Для создания сортов гороха (Pisum sativum L.) с высокой кормовой продуктивностью необходимо включать в селекционный процесс листочковые формы вместо более технологичных усатых сортов. Цель исследования — анализ коллекции гороха листочкового морфотипа для селекции на кормовые цели. Материалом для исследования послужили 20 образцов гороха листочкового морфотипа. Образцы оценивали по укосной и зерновой продуктивности. Погодные условия в годы проведения исследований отличались от среднемноголетних значений: 2018 год был очень засушливым (ГТК — 0,60), 2019 год — засушливым (ГТК — 0,89). Урожайность зависела от биологических особенностей сорта и погодных условий годов исследований. Следует отметить высокую продуктивность сорта гороха полевого Интенсивный 92: в оба года он попал в верхнюю часть ранжированного списка, превысив стандарт. В среднем по урожайности зелёной массы сорт Интенсивный 92 превосходил стандарт Радомир на 3,40 т/га, по урожайности семян — сорт Орпела на 0,10 т/га. Рентабельность производства зелёной массы сорта Интенсивный 92 оказалась на 53,7% выше стандарта. По рентабельности производства зерна сорт Орпела превысил стандарт на 8,8%. Выделены источники важных хозяйственных признаков: для селекции на увеличение урожайности семян — горох полевой Орпела; урожайности зелёной массы — сорта Апостол и Интенсивный 92; в качестве источника семенной продуктивности растений — сорта Тюменский кормовой, Шал, Орпела; устойчивости к полеганию — Альбенс и Орпела; устойчивости к аскохитозу и тле — Clause и Id 29200910. The investigation took place in the forest-steppe of the Eastern Siberia in 2018–2019. To create pea (Pisum sativum L.) varieties with high feed productivity, it is necessary to include leafy forms in a breeding process instead of leafless varieties suitable for machine harvesting. The research aimed at screening a collection of leafy peas for breeding feed varieties. 20 leafy varieties were analyzed according to their green mass and grain productivity. Weather conditions differed from the long-term average values: 2018 was very dry (hydrothermal index = 0.60), 2019 — dry (hydrothermal index = 0.89). Productivity depended on plant biology and meteorological conditions. Pea variety “Intensivny 92” showed high productivity ; it hit the top of the ranked list, exceeding the standard in both years. “Intensivny 92” exceeded the standard “Radomir” in green mass yield by 3.40 t ha-1 and“Orpela” — in grain productivity by 0.10 t ha-1. The profitability of green mass production of “Intensivny 92” was 53.7% higher than the standard. The profitability of “Orpela” grain production exceeded the standard by 8.8%. The sources of economically important traits were found: field pea “Orpela” — to increase grain yield; “Apostol” and “Intensivny 92” — for high green mass yield; “Tyumenskiy kormovoy”, “Shal”, “Orpela” — high seed productivity; “Albens” and “Orpela” — lodging resistance; Clause and Id 29200910 — resistance to Ascochyta leaf spot and aphids.

The research was carried out with the aim to establish the formation regularity of both yield and its elements, as well as to formulate technological and quality indicators of bare-grained oats under the influence of different sowing periods. The studies were carried out in the conditions of the northern forest-steppe zone of the Kemerovo region (Russia) on the territory belonging to the Kemerovo Research Institute of Agriculture, a branch of the SFNCA RAS in 2018-2019. The soil of the site is leached chernozem, heavy loamy in granulometric composition, of medium thickness. The object of research was the mid-season variety of bare-grained oats Bare-grained. The predecessor is pure steam. Sowing was carried out in three periods: early – on May 4 (when the soil was physically ripe, subsequent ones with an interval of 8-10 days, depending on the prevailing weather conditions), medium - on May 12 and 14, late - on May 20 and 24. Against the background of each sowing period, the seeding rates of 4.0 were studied; 4.5; 5.0; 5.5; 6.0 million crops/ha. It has been established that the optimal sowing time for obtaining high quantitative indicators (yield, number of grains, grain size) of bare-grained oats in the northern forest-steppe of the Kemerovo region is an early period (first decade of May); while a later period (third decade of May) is more promising for such high-quality indicators as protein content, fat in grain, essential and nonessential amino acids, etc. The optimal seeding rate for bare-grained oats at early sowing period is 4.0-4.5 million/ha. At a later period, it is advisable to increase the seeding rate to 5.0-5.5 million/ha.
