IMPACT OF APPLICATION RATES AND TIME OF THE GROWTH REGULATOR FITOVITAL ON THE YIELD AND QUALITY OF BUCKWHEAT GRAIN

Abstract

The article presents the results of the studies on the efficiency of different rates and time of application of the growth regulator Fitovital, WSC when cultivating buckwheat. It was established that the highest grain yield was obtained when the growth regulator Fitovital, WSC (0.8 l/ha) was applied at the budding stage of buckwheat without mixing it with the herbicides Biceps Garant, EC + Agron, SC (0.75 + 0.22 l /ha). Fitovital, WSC application had the most significant effect on hull content, reducing that indicator by 1.2–3.4% or 4.6–13.0% relatively, depending on the rate and time of application. When Fitovital, WSC was applied without herbicides at the budding stage (0,6 l/ha) grain hull content was the lowest. As a rule, Fitovital, WSC did not have a positive effect on grain evenness, grain yield and protein content.
