The effect of different doses of different biostimulants on the yield of oily sunflower

Abstract Biologically active substances (BASs), including plant phytohormones-regulators of growth and development, are becoming increasingly important in agriculture activities. Their use allows to better realize the genetic potential crops, increase resistance plants stress factors biotic abiotic nature, as a result yields improve quality. In this research, it was aimed at researching effect different doses biostimulants on yield oily sunflower. research experiment, “Methods field experiments” developed by B. Dospekhov used. According results, found that microbio-fertilizers, biostimulants, immunostimulants had positive growth, development seed formation local Dilbar variety sunflower, weight 1000 seeds. When biodux biostimulator applied 1.0 ml/t variant, height sunflower stem 28.5 cm higher than control 7.1 “UzGUMI” standard. Furthermore, when MERS microbiota fertilizer used 2.0 ml/ton 25.5 higher, 4.1 UzGUMI The be heavier other especially variant using microbiota.
