Grain sorghum is a drought-resistant crop and forms a high grain productivity and biomass as a raw material for the production of bioethanol and solid fuel in difficult soil and climatic conditions. The aim of the research was to establish the influence of sowing seeds method of the grain sorghum varieties on the photosynthetic activity of crops in the conditions of the Right-Bank Forest-Steppe of Ukraine. Methods. Field, laboratory, mathematical and statistical. Results. It has been proved that the leaf surface area of grain sorghum plants reached its maximum during the period of "throwing out panicles - flowering". It was the largest when sowing with a row spacing of 45 cm and at a plant density of 150 thousand units/ha – 34.8 thousand m2/ha for the Dniprovsky 39 variety and 32.7 thousand m2/ha for the Vinets variety. With the standing density of 200 thousand pieces/ha, the Dniprovsky 39 variety has 37.8 thousand m2/ha, the Vinets variety – 35.6 thousand m2/ha and with the density of 250 thousand pieces/ha, respectively 38.2 and 36.9 thousand m2/ha. The photosynthetic potential also changed depending on the size of the assimilation surface during the growing season. It was the highest when sowing seeds with a row spacing of 45 cm and amounted to 1.13–1.29 million m2/ha for the Dniprovsky 39 variety and 1.10–1.22 million m2/ha for the Vinets variety. When sowing with the row spacing of 15 cm, this indicator was 0.86–1.07 million m2/ha for the Dniprovsky 39 variety and 0.84–1.09 million m2/ha for the Vinets variety. When sowing grain sorghum seeds with the row spacing of 70 cm, the photosynthetic potential was 0.83–1.03 million m2/ha and 0.78–0.95 million m2/ha, respectively. An increase in the plant density from 150 to 250 thousand pieces/ha of grain sorghum contributed to an increase not only in the assimilation leaf surface, but also in the photosynthetic potential. The high net productivity of photosynthesis was observed when sowing seeds with the row spacing of 45 cm and for the Dniprovsky 39 variety it was in the range of 3.36–3.94 g/m2 per day, for the Vinets variety — 3.32–3.81 g/m2 in day. Conclusions. It was found that with a change in the feeding area of grain sorghum plants, the assimilation surface of leaves, photosynthetic potential and net productivity of photosynthesis change.

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.

The work presents the results of studies for 2017-2019, aimed at developing methods for increasing the productivity of sunflower hybrids cultivated according to the Clearfield system when using the microfertilizing mixture Agromineral in the forest-steppe zone of Middle Volga region. The results of the studies showed that the safety of plants at the time of harvesting is up to 91.8%; the maximum safety is achieved when processing crops by vegetation with Agromineral microfertilizing mixture at a dose of 3 l/ha. The leaf area increased until the budding phase, reaching a maximum of 99.2 thousand m2/ha, on a mid-season hybrid when processing crops with a dose of 3 l/ha, and then, due to drying of the lower leaves, it begins to decrease to the phase of the onset of flowering to 37.8 ... 57.9 thousand m2/ha. The maximum value of the photosynthetic potential is formed by crops of the mid-season hybrid 8N477KLDM - 4.781 million m2/ha days. The use of fertilizers and micronutrient mixtures increases its value and, as a result, increases productivity by 9.09 ... 9.36 kg/ha with an absolute indicator of 27.2 ... 33.2 kg/ha.

Biological farming throughout the world is becoming a necessity for the production of safe products, and the preservation of fertility and biodiversity. In this direction, there is a significant interest of the scientific community in the perennial culture – cup plant. The cup plant has a wide range of uses in economic activities and due to its high resistance to diseases and pests, the long-term use of its plantations without replanting, and the accumulation of a significant mass of organic matter in the soil, it can be used to expand the species diversity of perennial grasses in the biological farming system. The aim of the study was to examine the influence of the seeding method and seeding rate on photosynthetic activity and dry matter productivity of the cup plant in the forest-steppe conditions of Western Siberia. It was found that with an ordinary method of sowing at a seeding rate of 4 million pcs/ha, the grass stand in the first cut had the highest rates of photosynthetic activity on average over the years of research: the leaf area was 14.8 m2 /m2 , the photosynthetic potential was 4.0 million m2 day/ha and the net productivity of photosynthesis was 2.0 g/m2 ⋅ day. In the second cut, the figures were 8.4 m2 /m2 , 1.9 million m2 day/ha and 2.8 g/m2 ⋅ day, respectively. The optimal density of herbage and active photosynthetic activity in the cup plant using this method of sowing contributed to a significant yield of dry matter of 12.6 t/ha with a high level of PAR absorption of 2.9%.
