THE INFLUENCE OF MICROBIAL PREPARATIONS ON PRODUCTIVITY OF GRAIN-CROPS IN NORTH STEPPE OF UKRAINE

Abstract

The influence of presowing seed treatment of corn, spring barley and winter wheat on growth, development and productivity of these cultures was studied. It was established that nitrogen-fixing and phosphate-mobilizing microorganisms and their combinations enhance biometrical parameters of plants, influence positively on the productivity and quality of grain comparatively to control.
