Effect of agrochemicals on productivity of sunflower

The paper considers the results of three years of research on the effects of agrochemicals Borogum and Bioneks on growth, development and productivity of sunflower seeds in conditions of Azov Rostov region zone. Found that the double processing of vegetating plants sunflower agrochemicals boosts the formation of aerial parts and improves quality indicators. The largest number of achenes was observed in the application of agricultural chemical products Bioneks 40:0:0 and 2:40:27 brands and amounted to 83,3-83,7 % that affected high yields of oilseeds. Vegetation processing agrochemicals Borogum contributed to higher yields of oilseed sunflower in comparison with control on 0,25-0,50 t/ha and Bioneksom 0,5-0,66 t/ha. The highest yield was obtained with crop spraying Bioneks brand 2:40:27 – 2,82 t/ha. Energetically and economically profitable to grow sunflowers when spraying plants agrochemicals Bioneks 2:40:27.
