Abstract
In this work, we studied biological products used for growing on barley. Empirical data on the influence of biological products on the development of barley, photosynthetic activity, productivity and profitability are presented. The experiments were carried out in the Rostov region in 2016–2020, the temperature regime, distribution and amount of precipitation were different from the long-term ones. When using Emistim, barley formed the largest leaf area on the plant, more than the control by 223%. The survival rate of barley was from 70,9 to 77,9%. Productive bushiness increased by 5–10%. Treatment of plants with Binoram and Emistim preparations formed an average of 1.34 productive stems on the plant, Vitazim and Biodux — 1,33. Under the influence of biological preparations the plants formed a full-fledged grain. Biodux and Binoram made it possible to obtain a mass of 1000 grains by 2,4 g more than the control. The highest yield was obtained when exposed to Emistim — 3,76 t/ha, which exceeded the control by 1,03 t/ha. Confidence at 95% significance level was noted for all variants. On average, over the years of experiments, it is most cost-effective to use Biodux for vegetation.
