Evaluation of the effect of different doses of biochar application on the yield of soybean cultivar sculptor in the conditions of аgroecological station of K.A. Timiryazev

Abstract

In the conditions of the academic fields of the Timiryazev Academy (Moscow, Russia), an experiment was conducted to evaluate the impact of biochar on soybean cultivar Sculptor. Plots of 0.25 ha were laid on arable sod-podzolic soils, the doses of biochar application were 3 kg/m2, 1 kg/ m2 and reference variant without application. The plots were established in triplicate. The results of the studies showed an improvement in a number of soil properties at 1 kg per m2, with more plant biomass, more stem pods per plant. With application of 3 kg per m2 - development of soybean variety Sculptor did not have the necessary effect, at the first stages soybean developed rapidly, but later only slow development of weed plants was noted. On the reference plots plants had a smaller biomass compared to the variant with the application of 1 kg per m2. Application of biochar to soybean crops shows a positive effect on yield and biomass of plants at the application dose of 1 kg per m2.
