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.

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.


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.

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.

Abstract. The purpose of the work is to study the influence of the growth regulator “Regoplant” and microfertilizer “Ultramag Kombi” on the photosynthetic productivity of the potatoes of the Barna variety based on the results of field experiments in the forest-steppe zone Republic of North Ossetia-Alania. Methods. Studies on the tasks were carried out in 2018–2020. at the experimental site of the NCRIMFA branch of the VSC of RAS in the conditions of the forest-steppe zone Republic of North Ossetia-Alania according to generally accepted methods. The soil of the experimental plot is medium-power heavy loamy leached chernozem, lined with pebbles. Results. It is established, that biological products under identical soil and weather conditions assisted different progress of plants and approach of phases of vegetation. For all variants of the experiment, the number of stems increased by 0,3–0,7 pcs., the height of the stems of potato plants – by 3,8–4,9 cm in comparison with the control. An intense increase in the mass of tops occurred when using a tank mixture (growth regulator “Regoplant” (25 ml/ha) + microfertilizer “Ultramag Combi” (0,75 l/ha)) – by 74 g/bush, or 15.5 % compared with the control variant. During the growing season, the sum of the photosynthetic potential (FP) was 1,070 thousand m2 •days/ha in the control, and on average 1198–1406 thousand m2•days/ha in the experimental variants. The greatest accumulation of dry matter was noted when using a tank mixture – 917 g/m2. The maximum pure photosynthetic productivity was observed in experimental variant IV – 6,52 g/m2•day compared to the control option. Scientific novelty. For the first time in the forest-steppe zone Republic of North Ossetia-Alania the effect of the growth regulator “Regoplant” and microfertilizer “Ultramag Kombi” on photosynthetic activity of potatoes was studied. Practical significance. The studies carried out make it possible to recommend in potato production the use of a tank mixture of an effective growth regulator “Regoplant” at a dose of 25 ml/ha and microfertilizer “Ultramag Combi” at a dose of 0,75 l/ha, as an ecologically safe and low-cost agricultural method when processing vegetative plants, providing an increase in yield and quality of tubers.

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 %.

Abstract. The purpose is to study the varietal characteristics of the photosynthetic efficiency of oats when applying fertilizers in Western Siberia. Methods. The research was carried out on an experimental field located in the northern forest-steppe of the Trans-Urals. Photosynthetic potential and net productivity of photosynthesis were determined by the Nichiporovich’s method. Results. The nature of the formation of the assimilation surface and the accumulation of biomass of oat varieties Otrada, Talisman and Foma at different levels of mineral nutrition was studied. The photosynthetic potential and the net productivity of photosynthesis are calculated. The share of the influence of weather conditions, agrophone and variety on the studied indicators is determined. The Foma variety was characterized by maximum leafiness, compared to the Talisman and Otrada. On a natural agrophone, its assimilation surface in the sweeping phase reached 36.0 ± 5.5 thousand m2, at Otrada and Talisman – 28.1 and 24.0 thousand m2 per 1 ha of sowing. A very strong variability of the leaf surface area in Otrada was revealed (Cv = 24 %). The use of mineral fertilizers enhances the development of the leaf apparatus by 44–50 % and causes competition between oat plants. A close positive correlation was revealed between the leaf area in the sweeping phase and yield (r = 0.72). The area of the assimilation surface of oats is affected by: weather conditions – 37 %; nutrition level – 30 % and variety – 25 %. It was found that the Otrada and Foma varieties have the same accumulation dynamics and form the maximum photosynthetic biomass by the sweeping phase. The nature of biomass accumulation depends on weather conditions by 39 %; on mineral fertilizers by 29 % and on the genotype of the variety by 17 %. The productivity of the studied varieties is formed by increasing the assimilation surface, rather than increasing the efficiency of photosynthesis. Scientific novelty. For the first time, the photosynthetic potential was determined and the efficiency of the net photosynthesis productivity of oat varieties of the Tyumen selection was revealed. The share of the influence of various factors in the formation of the oat crop in the conditions of the Northern Trans-Urals has been established.

Sowing is one of the most important agronomic measures in soybean cultivation. However, today in Ukraine there is no universal approach to defining the optimal sowing time. Some researchers assert that one should rely on the calendar period of sowing; other specialists argue that the spring features should be the primary determinant; the third group think that the thermal conditions at a depth of 10 cm is the main factor; and according to the fourth opinion, soil and clime characteristics are critical. The hydrothermal conditions in the years of our research deviated significantly from the annual average. Thus, the hydrothermal coefficient during the soybean growing period in 2018 was 0.34, and in 2019 it was 0.52, indicating that the cultivation conditions were arid (0.5 <HTC <0.9). The experiments showed a clear downward trend in the growing period length and upward trends in the field germinability of seeds and leaf surface area when soybean was sown in soil warmed to 14-16оС on May 10-15. In this case, the biometric parameters of soybean plants improved, and the yield increased by 0.15-0.16 t/ha. Keywords: soybean varieties, weather conditions, sowing time, field germinability of seeds, plant survival, photosynthetic and symbiotic activities of plants, grain yield.
