USE OF GROWTH PROMOTERS AS ANTIDEPRESSANTS TO HERBICIDE IN BARLEY CROPS
Abstract
There are results of a study on growth promoters as antidepressants to a herbicide used on barley crops presented in this article. Weeds reduce crop yields. Herbicides are the main effective means of controlling weeds, but they are phytotoxic. Application of plant growth stimulants with herbicide reduces the pesticide load on the plant. The aim of the research was to study growth stimulators as antidepressants to herbicide on barley crops. It was found that herbicide Agritox reduces the number of weeds by 9,5 times. Its effectiveness is 91,4%. Efficiency of tank mixture of growth stimulators Ecopin and Biosil with herbicide Agritox was 85,5% and 87,5%. When spraying barley crops with herbicide Agritox, the yield increase was 0,24 t/ha; with the tank mixture of Agritox + Ecopin was 0,42 and Agritox + Biosil was 0,49 t/ha. Growth stimulants increased the number of plants by 14 and 20 pieces per m2, the number of grains per ear was increased by 3 pieces, weight of 1000 grains was increased by 0,8 and 1,5 g.
