INFLUENCE OF BIOLOGICAL PREPARATION STYMPO ON PROCESS OF FORMING ТO THE PRODUCTIVITY OF SORTS OF WINTER SOFT WHEAT

Abstract

The work shows the effect of plant growth regulators of biological origin Stympo on the growth processes and biological productivity of winter wheat of sorts Epoha Odeska, Zapashna, Fermerka and Statna in the conditions of Southern Steppe of Ukraine. It has been established that the biomagnifier Stippo increases the number of productive shoots, increases the weight of the grain in the ear, increases the yield of the commercial part of the harvest, which ultimately increased the biological yield of soft winter wheat. In the analysis of a two-factor experiment, the influence of factor A (variety) and the interaction of factors AB (A-grade, B-bioproduct Stippo) on the yield of winter wheat is much greater than that of the Stepmpo biological drug (18.73%). The study of the effect of the Stimulo preparation on the growth, development and formation of winter wheat yields will enable the implementation of genetic potential and develop a recommendation for its implementation in agro-industrial production
