ЭФФЕКТИВНОСТЬ ПРИМЕНЕНИЯ МИКРОУДОБРЕНИЙ С ЭЛЕМЕНТАМИ РЕГУЛЯТОРОВ РОСТА НА СОЕ

Abstract

The work was performed in 2018–2019 in the Chuvash Republic on light gray forest soils. Studies were conducted to determine the impact of various sowing methods and microfertilizers Bloom & Grow and Immune System on the formation of productivity of soybean varieties USKhI-6. The scheme of the 2-factor experiment included the following options: microfertilizers (factor A) - without fertilizers (control) and using microfertilizers; seeding methods (factor B) - ordinary with a row-spacing of 15 cm and wide-row (30 cm). The highest plants were formed with a wide-row method of sowing - 6.7 ... 11.8 cm higher than in the version with the ordinary method of sowing. The introduction of micronutrients also significantly increased the value of this indicator by 2.3 ... 7.4 cm. The highest attachment of the lower beans was noted in the variants using micronutrients (10.3 ... 10.7 cm). The method of sowing did not have a significant effect on this trait. A wide-row method of sowing contributed to an increase in branching and the number of internodes on the main stem, compared with the ordinary. The maximum in the experiment the number of beans (38.2 pcs.) and seeds (58.2 pcs.) from one plant, as well as the weight of 1000 seeds (145.1 g) were noted during wide-row sowing using micronutrient fertilizers. In the same embodiment, the plant safety was 87%, and the yield was the highest in the experiment - 2.04 t/ha. The calculation of economic efficiency was carried out on the basis of technological maps at current regulatory rates. Soybean cultivation was economically viable; profitability for all options was 83.3 ... 106%. The largest (106%) it was with a wide-row method of sowing with the introduction of fertilizers.
