Abstract
The article reveals the dependence of the symbiotic activity of soybean plants on the ongoing methods of tillage. The studies were carried out in the steppe zone of Kabardino-Balkaria in the period from 2015 to 2019. on ordinary chernozems. During the experiments, three variants of soil cultivation were used: moldboard plowing to a depth of 20-25 cm, flat-cut plowing to a depth of 20-25 cm and shallow loosening to a depth of 10-12 cm. Soybean varieties were studied: early-ripening – Avanta, late-ripening – Vilana. The predecessor for soybean plants was corn for grain, the sowing method was wide-row with a row spacing of 45 cm. As a result of the study with the use of moldboard plowing, the yield was 12-14% higher than with flat-cut plowing.During periods of sufficient moisture supply (2016 and 2018), soybean plants formed the best yield relative to the indicators obtained under conditions of insufficient moisture (2015, 2017 and 2019). When using moldboard plowing, the soybean yield was 17.2 c/he under conditions of sufficient moisture supply, and with moisture deficiency – 15.8 c/he. Favorable conditions for the effective passage of photosynthesis and the work of the symbiotic apparatus of soybean plants are created while minimizing tillage, which affects the value and indicators of the yield structure. Studies have shown that early sowing periods have advantages over late ones, which is confirmed by high yield structure indicators and indicate a more efficient use of soil moisture reserves by soybean plants in spring.
