Relation of nitrogen uptake and yield of total aboveground biomass accumulation dynamics on barley development stages, sowing rates and fertilizer

The main agrochemical indices of the Mountain Shirvan soil, which are changeably supplied with moisture, are presented. In 2016-2018 studies were carried out on 3 experimental plots and controls, using standard techniques. The dry ground biomass of the Jalalabad-19 barley was harvested and the dependence of nitrogen adsorption on the norms of planting and fertilizers, as well as the phases of barley development, as well as the dependence of the amount of dry ground biomass on the amount of precipitation over the years. The data on the assimilation of nitrogen in the full phase of plant ripening with fertilizer N60P45K45 and the seeding rate of 140 kg/ha, at 14.65 and 6.17 kg/ha compared with the seeding rate of 120 and 160 kg/ha are given.
