The reaction of soybean varieties to the use of a biological product

Relevance. In the conditions of Central Black Earth region in farm “Yaroslav Wise” Starooskolsky district Belgorod region, five soybean varieties (Belgorodskaya 48, Bara, Victoria, Opus and Kassidi) were studied on nutritional backgrounds — without seed inoculation biological treatment (control), using only with use a product against background inoculation. Methods . The experimental differed rainfall patterns amount heat, their distribution was especially uneven 2020, that had significant negative effect yield all varieties. soil plot is typical medium-thick chernozem, medium-humus, heavy loamy texture. advantages variety Opus, plants which formed large height, air-dry mass, leaf area, greater number mass nitrogen-fixing nodules roots, revealed. Plants this provided higher level agro-backgrounds. Results. varied from 32,5 centners per hectare (control) to 36,2 (when Biogor, Zh). content collection protein also cultivar agrophones. comparison control, by 4% (background control), 4,9% seeds 6,1% when product. same pattern observed assessing oil collecting sowing. Inoculation inoculant Nitragin, KM improved plant development increased productivity, as well profitability cultivation varieties, an average 27%, while 15,1%.
