Biostimulants of growth in the production process of grain crops

Abstract

The role of biostimulants of growth of various natures in the production process of spring wheat variety Zlata was studied, depending on nitrogen nutrition conditions, and was carried out under field conditions.The experiments assessed the activity of the plant assimilation apparatus and the formation of the yield of wheat plants using biostimulants of various natures by spraying vegetative plants. The studies found that the greatest effectiveness of the studied drugs was observed under conditions of optimal provision of nitrogen nutrition to wheat plants. It has been established that the preparations Epin-Extra, Emistim and Hardy increase the efficiency of the assimilation apparatus of spring wheat plants, which led to the receipt of large increases in grain weight under conditions of optimal provision of wheat plants with nitrogen nutrition.
