THE INFLUENCE OF SEEDING RATES AND FOLIAR FEEDINGS ON THE EFFECTIVENESS OF GROWING OF SPRING BARLEY VARIETY DOKUCHAEVSKIY 15

Abstract

The article presents the results of studies conducted during 2012–2014 years on the experimental field of KhNAU named after V. V. Dokuchayev about the impact of the application of different options for seeding rates and foliar application on the variability of grain yield of spring barley varieties Dokuchaevskiy 15. It was set high economic and bioenergetic efficiency of foliar application crops. The highest productivity of grain and the best indicators of economic and bioenergetic efficiency of cultivation were obtained on options for crop seeding rate of 5,0 million seeds/ha. It was also found that the optimization of seeding rate provides the increase of effectiveness of foliar application.
