Influence of bio-preparations and their multiplicity of application on stability of soybean yield in Amur region

Abstract

The article presents data on the influence of Borogum Mo and Phytosporin-M biopreparations on the yield and composition of oil soybean admixture in different meteorological conditions of Amur region. The experiment included options: Factor A (preparations) - 1. Without preparation (water); 2. Borogum Mo; 3. Phytosporin-M; 4. Borogum Mo + Phytosporin-M; Factor B (number of treatments) - 1. Without treatment. 2. One time. 3. Two times. 1. Factor B (number of treatments) - 1. The conducted researches have shown that the greatest yield of soybean sowing is provided on the average for two years at spraying of plants once in the end of June with Borogum-Mo and a mixture of Borogum-Mo + Phytosporin-M preparations - 2.87 t/ha. When Borogum-Mo is treated, the number of frost seeds decreases, and when treated with Phytosporin-M, the number of affected diseases decreases in comparison with control plots. According to the basic norm of oilseed admixture all used preparations provided the yield of pure soybean seeds.
