Abstract

Today, measures to solve the problems in the world market of the products obtained from the agricultural grain crops and the blue pulp for livestock, which are grown all over the world, are an urgent issue. In the experiment, the amount of P2O5 during the ripening period was 23.2-10.9 mg/kg, and it was distinguished by the high degree of absorption of the plant in the control of the options, where mineral fertilizers were used in the norms of N-120, P2O5-85, K2O-60 kg/ha. Against the background of these fertilizers, it was observed that when they were used with 20 tons of manure in the main fertilization, acceptable indicators were obtained and the availability of soil was high.
