Varietal assortment of soybean for organic production

Abstract

The goal was to investigate and determine prospective for organic production and seed production varieties of soybean of domestic and foreign selection, using organic technology in the Forest-Steppe zone of Ukraine. To determine the yield of seeds measuring-weight method was used, to identify plant damage caused by phytopathogens the biological method was used and to determine the reliability of the results statistical, dispersion and regression methods were used. The possibility of growing soybeans using organic technologies is proved. The efficiency of agrotechnical measures to control weeds in organic production conditions was analyzed. Optimal timing of sowing organic soybean seeds in the Forest-Steppe zone of Ukraine is determined. The most promising for organic production and seed production varieties of soybean of Ukrainian and foreign selection were selected. The research of the Skvyrska experimental station of organic production of the Institute of Agroecology and Environmental management of NAAN proved the possibility of growing soybeans using organic technologies. By results of researches it is established, that all investigated sorts are suitable for organic production and seed production. The most promising for organic production and seed production, in view of the absence of disease, high competitiveness in relation to weeds and relatively high yields, are soybean varieties Lisbon, Cordoba and Kent. The peculiarities of soybean production using organic technologies are directly related to soil cultivation and the use of resistant varieties to diseases and pests.
