Use of biological products in conditions of organic manufacture of soya

Abstract

The purpose. To assess influence of application of biological products on development and density of segetal vegetation on organic crops of soya in view of change of agroclimatic parameters. Methods. Researches had been spent on the basis of Skvyra experimental station of organic manufacture of Institute of agroecology and nature management of NAAS during 2015 – 2017. They studied density of weeds on organic crops of soya of variety «Suziria» by means of quantitatively-weight account of segetal vegetation (according to O.V. Fisiunov) and determination of specific conformity of plants of weeds (according to I.V. Veselovskii). The area of leave surface of soya was determined according to Z.M. Gritsayenko. Statistical processing of experimental data was made according to B.A. Dospehov technique. Results. It is determined that under the influence of biological products physiological processes of plants of soya become more active. That increase the area of leave surface. It is noted that the soya actively competes with segetal vegetation for vital space, suppressing it. Result of stimulation of growth of soya under action of biological preparations is the increase in productivity of agricultural crop. Conclusions. Application of complex of biological products in conditions of transition period to organic manufacture promotes increase in competitiveness of cultural plant to segetal groupings and, as consequence, stabilization of agro-eco-system.
