For the conditions of the western forest-steppe zone of Ukraine, it is important to choose the optimal sowing period, seeding rates for efficient provision of oil flax plants with nutrients and the realization of their genetic potential. When establishing the norms of seeding flaxseed, it is advisable to take into account soil fertility, precursors, weight of 1000 seeds, etc. The studies were conducted in 2016-2018 at the research field of the Institute of Agriculture of the Carpathian region of the NAAS in a five-field crop rotation on the gray forest surface-covered soil type with average fertility rates. Three sowing rates (4, 6 and 8 mln seeds / ha) of Original and Liryna flax varieties were sown, which were sown in three terms: early (at the earliest opportunity), 10 and 20 days after the early term. On survival of plants during the growing season the sowing density had a significant effect. The number of plants that have fallen during the growing season before the start of harvesting in the full ripeness phase is in the range of 9.7… 15.2 % when sown in the first and second term and 10.7…22.5 % when sown 20 days after the first possibility of entering the field (3rd sowing period). Increase of seed rate to 8 million pieces. / ha caused an increase in the rate of plant loss during the growing season. The Original variety was characterized by a higher plant survival during the growing season under the sowing periods compared to the Lirina variety. The highest seed productivity (2.57 t / ha) was obtained in the Lirina variety for sowing 6.0 million pieces / ha and sowing at the first opportunity to enter the field. Sowing in 10 and 20 days after the first term caused a decrease in the yield of the Lirina variety by 0.16-0.35 t / ha, for the Original variety - by 0.36-0.45 t / ha. The Original variety proved to be more productive with the yield of flaxseed (3.65 t / ha) compared to the Lirina variety (3.14 t / ha), provided the early sowing rate of 8.0 mln seeds / ha. The use of late sowing conditions led to a decrease of this indicator in the range of 5.3-20.0%. Delaying the sowing period from the first opportunity to enter the field for 10 and 20 days led to a decrease in the mass index of 1000 seeds for the Original and Lirina varieties by 0.1-0.2 g (at the control of 7.0 g). The highest yield of oil per hectare was provided by the Lirin variety for the first sowing period and the seeding rate of 6.0-8.0 million similar seeds / ha - 1.15-1.16 t / ha. The use of late sowing dates reduced the yield of oil by 1.7-18.4% for both varieties studied.

The results of studying naked oat yield indicators depending on different sowing dates and seeding rates are presented. The study was carried out in 2016-2020 in a field experiment in Western Siberia. Samples of different groups of the crop ripeness were studied: mid-early variety Gavrosh and mid-ripening variety Ofenya. The duration of the growing season of naked oats was influenced by meteorological factors. There was a tendency observed for a decrease in the duration of interphase periods and the growing season as a whole from an early sowing date to a later one by 4-10 days for the Gavrosh variety and by 8-10 days for the Ofenya variety. The yield of the Gavrosh variety at an early sowing period significantly exceeded the same indicator at a mid-period by 17.6% and at a late period - by 19.0%, of the Ofenya variety - by 10.9% and 16.2%, respectively. The increase in the yield for the early sowing period of the mid-early variety Gavrosh relative to the middle and late sowing dates was determined by a larger grain size (r = 0.6929 ... 0.9535 at R = 0.5140). For the midripening variety Ofenya, the number of productive stems per unit area (r = 0.7444 ... 0.9054 with R = 0.5140) and the weight of 1000 grains (r = 0.5350 ... 0.8297 at R = 0.5140) were of more importance in the years of research on all variants. The most optimal seeding rate for naked oat varieties is 5.0-6.0 million germinating grains/ha. At this rate, it was not the maximum manifestation of individual indicators of the yield structural elements, but a combination of their average values was noted.

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.

Purpose. To establish the influence of sowing terms and seeding rates on the formation of seed yield of soybean varieties with different growing periods in the Western Forest-Steppe natural zone of Ukraine. Methods. Field experiment, calculation and weight, mathematical statistics. Results. It was found that the studied soybean varieties with different growing periods react differently to growing conditions. Among the studied factors, the seeding rate, more than the sowing period, influenced the formation of soybean seed yield. Inparticular, the studied soybean varieties Diadema Podillya, KiVin, Knyazhna and Khutoryanochka in all terms of sowing, the highest grain yield formed at the seeding rate of 900 thousand germinating seeds per 1 ha, while the Triada variety – at the seeding rate of 700 thousand germinating seed sper 1 ha. The increase in yield compared to the seeding rate of 700 thousand germinated seeds per 1 ha was in the Diadema Podillya variety – 8,9-19,2%, in the KiVin variety – 12,4-15,6%, in the Knyazhna variety – 16,0-22,9% and in the Khutoryanochka variety – 4,2-10,1%. Reducing the seeding rate to 500 thousand germinating seeds led to a decrease in productivity for all sowing periods, in the Diadema Podolia variety – by 15,3-23,7%, in the KiVin variety – by 19,6-26,0%, in the Knyazhna variety – by 13,6-18,3%, in the Khutoryanochka variety – by 9,9-11,0% and in the Triada variety – by 17,8-25,7%. Higher indicators of seed yield all the studied soybean varieties formed during the late sowing period. Conclusions. The studied factors had a significant influence on the formation of seed yield of all soybean varieties that were studied – the timing of sowing and seeding rates, as well as the weather conditions of the growing season. The studied soybean varieties reacted differently to a decrease or increase in the seeding rate, however, higher yield indicators were formed due to the late sowing period.

The article presents the results of research on the formation of corn yield for grain depending on the elements of cultivation technology in the Forest-Steppe of Ukraine. The goal of the research was to identify the influence of plant density and fertilizer system on the yield of corn hybrids for grain. The research was conducted during 2017-2019 in the research field of Bila Tserkva National Agrarian University (Bila Tserkva NAU). Research methods: field, calculation and statistical. Results. Regularities of growth, development and formation of yield by plants are revealed, both in concrete conditions of years of researches, and taking into account average long-term values taking into account features of hybrid-oriented technology. According to the results of the experiment it was recorded that the maximum yields for growing early-maturing maize hybrid DN PIVYHA with FAO 180 in general were obtained at a pre-harvest density of 75 thousand units/ha and the use of combined organo-mineral fertilizer system - 11.09 t/ha; medium-early maize hybrid DN ORLYK, FAO 280 in general in the experiment provided a grain yield of 9.60 t/ha, and in terms of 2017 - 7.86 t/ha, in 2018 - 11.22 t/ha and in 2019 - 9, 72 t/ha, but the medium-ripe hybrid of corn DN SARMAT, FAO 380 provided a grain yield of 10.81 t/ha, and in the context of 2017 - 9.31 t/ha, in 2018 - 11.68 t/ha and in 2019 - 11.44 t/ha. Significant influence on the formation of the yield of corn has a hybrid factor (27 %), fertilizer system determines the level of productivity by 21 % and interacts closely with the conditions of the growing season (factor BV 9 %), growing season conditions also determine the level of productivity of corn plants (19 %), and the pre-harvest density determines this feature by 18 %. Conclusions: In the conditions of the Right Bank part of the Forest-Steppe of Ukraine there is an increase in the level of productivity of maize hybrids from early to medium-ripe hybrids, regardless of the influence of other experimental factors.

The results of field studies for 2017 - 2019 are presented. yields of perennial grasses sown at different times of the growing season. Spring, summer, and winter sowing periods were compared. Alfalfa, clover, rump, and also their mixtures were sown in 2017 under the cover of barley. The value of the cover crop yield of spring and summer sowing periods did not differ significantly and amounted to 4-5 t / ha of absolutely dry matter. Winter barley crops have not formed. On average, over 2 years of use, the highest yields were observed in alfalfa-crust grass mixtures - 3.4 t / ha of absolutely dry matter. The lowest yield was obtained in the single-species seeding of the rump. Correspondingly, in the spring, summer and winter periods of sowing, the yield of rump was 1.6; 1.1 and 1.3 t / ha. With a late sowing period, the yield of perennial grasses is significantly lower compared to spring and summer. With winter sowing periods, the yield was the highest for grass stands of alfalfa and alfalfacrust grass mixture - 2.3 and 2.4 t / ha. It should be noted that in the second year of use, the yield by the sowing dates in single-species crops and grass mixtures is leveled. The winter crops of perennial grasses in the first year of use formed a low yield. Only in the second year (third year of life) the productivity of perennial grasses of winter sowing began to increase. Consequently, in the area under perennial grasses of the winter sowing period, during one growing season (the next year after sowing), the crop was not actually formed. Based on the data obtained, production can be recommended for spring and summer planting of perennial grasses under the cover of barley. The winter sowing period provides economically valuable crop yields only by the third year of life.

The results of studies on the dynamics of the formation of the area of leaves of plants of beetroot canteen depending on varietal characteristics and sowing time in the conditions of the Forest-Steppe of Right-Bank Ukraine are presented. The dependence of the growth and development of beetroot plants on varietal characteristics and sowing dates, as well as on weather conditions that were in the studied time, was revealed. The largest number of leaves in the phase of intensive root formation was formed by plants with a sowing period of I decade of May: 13.3 pcs. / plant – Bordo Kharkivskiy, 13.1 pcs. / plant – Opolskiy. The greatest mass of the root crop in the phase of intensive root formation was planted at a sowing period of the third decade of April: the Bordo Kharkivskiy – 72.4 g, the variety Opolskiy – 43.5 g. The same pattern was observed when taking into account the mass of the aerial part of beetroot. In the Bordo Kharkivskiy variety, it varied from 92.4 g to 87.5 g depending on the sowing time, in the Opolskiy variety from 33.7 g to 31.7 g, that is, the beet plants of the Bordo Kharkivskiy cultivar formed a significantly larger mass of the aerial part in comparison with the Opolskiy variety. Plants were sown with the largest leaf area at a sowing period of the 3rd decade of April: in the Bordo Kharkivskiy – 1.2 – 4.0 thousand m2 / ha, in the Opolskiy variety – 1.0 – 2.3 thousand m2 / ha. According to the results of the crop accounting, it was found that it depended on the variety and sowing period of beetroot. On average, over the years of research, the highest yield was observed with a sowing period of the third decade of April: 63.1 t / ha for the Bordo Kharkivskiy variety, 55.9 t / ha for the Opolskiy variety.

The authors showed the results of studies of productivity parameters of different early maturing maise hybrids depending on the method of sowing. Experiment included 5 variants: single- seeded hybrids Kubansky 101 and Kubansky 500, Kubansky 101 + Kubansky 500 (50 + 50% of the full seeding rate), Kubansky 101 + Kubansky 500 (25 + 75%) and Kubansky 101 + Kubansky 500 (75 + 25%). The authors carried out a biological yield survey on 10 September. This recording showed that the ultra-early-ripening hybrid Kubansky 101 CB was in the phase of milk-wax maturity of the grain, and the late-ripening Kubansky 500 CB was in the phase of cob formation. In single-species crops, the yields were naturally higher. The late-maturing hybrid yielded 82.0 t/ha, 38.1 t/ha higher than the ultra-maturing hybrid. However, the dry matter yield of the second hybrid was 15.9 % higher, and the cob yield was 29 % higher. The dry matter concentration of the hybrid Kubansky 500 was only 18.8 %. The hybrid Kubansky 101 CB had a dry matter concentration of 34.7 %. Different variations with the ratio of hybrids of different ripeness groups in the sowing showed that in green matter yield, the variants where the proportion of late-ripening hybrid is higher are superior. Thus, the presence of 75% hybrid Kubansky 500 CB allowed obtaining the highest yield of 77.2 t/ha. This yield is almost two times higher than the yield of the single-variety ultra-ripening hybrid (43.9 t/ha). However, the dry matter concentration here was 20.2 %. According to the biochemical analysis of the silage batches harvested, all the forages were benign. No oily acid was detected, and lactic acid predominated over acetic acid. Hay prepared from hybrid Kubansky 101 SV was 33.8% in dry matter content, which compares favourably with silage prepared from hybrid Kubansky 500 SV and mixtures with Kubansky 101 SV. The hybrid Kubansky 500 SV and mixtures with Kubansky 101 SV accounted for 21 % dry matter content. In silage prepared from hybrid Kubansky 101 SV, the percentage of dry matter is 24.2-25 %.

The results of studying resistance of mid-ripening spring wheat cultivars to root rot in the forest-steppe zone of Irkutsk region are presented. The study was conducted in a two-factor field experiment. Factor A – mid-ripening spring wheat cultivars: Tulunskaya 11 (control), Zoryana, Маrsianka, Stolypinka (new cultivars). Factor B – seeding dates: May 10, 20, 30, preceded by fallow. The experimental plot area was 70.0 m2. The experiment was repeated three times. Plot arrangement was randomized. Root rot prevalence was determined during the tillering phase of the crop. In 2018, the sowing dates did not affect the disease due to the long spring-summer drought (May-June) and a higher average daily temperature compared to long-term average values. In arid and cold conditions of May 2019, with the late sowing period (May 30), root rot prevalence was significantly lower than when sowing on May 10 and 20. In 2019, a higher level of the disease was registered than in 2018 by 14.3%. Significant differences in root rot prevalence in both years of research were noted between the control cultivar Tulunskaya 11 and the new cultivars of spring wheat Zoryana and Stolypinka. In the tillering phase of the latter two, disease indicators were lower by 5.6% and 10.5% in 2018, and by 8.8% and 7.9% in 2019, respectively. Маrsianka cultivar was at the control level for this indicator. The best cultivar under study was Stolypinka, which was not only less affected by root rot, but also gave a statistically significant yield increase of 0.16 t/ ha in 2018 and 0.22 t/ha in 2019.

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.
