CROP YIELD OF WINTER BARLEY GRAIN WITH THE APPLICATION OF VARIOUS GROWING TECHNOLOGIES

The experiment considered the influence of different methods of agricultural technologies on the yield of winter barley in the dependence of the investigated factors. Field experiments were carried out in the fields of the central experimental base of the Kashkadarya branch of the Research Institute of Grain and Legumes in the Karshi district of the Kashkadarya region under conditions of irrigated light gray soils. Stationary experience is represented by the following factors: the level of fertility (factor A); fertilizer system (factor B); plant protection system (factor C) and methods of basic soil cultivation (factor D). The relationship between the influence of the level of soil fertility, fertilizer rates, plant protection products, tillage system and yield, and crop structure of the promising winter barley variety Mavlono was determined. It has been established that (fertilizers, tillage, sowing method, means of protection) increases the yield of winter barley and positively affects the elements of the yield structure. The yield increase in comparison with the control changed from 10.4 to 26.8 c/ha. The statistical processing data show that the fertilizer system (35.8%) and soil cultivation (27%) had a certain influence on the number of productive stems; the fertilizer system (44.6%) influenced the spike size, the fertilizer system (28%) and the tillage (32.8%) had influence on the amount of grain in the spike and influenced the mass of grain from the spike.
