Abstract
The research purpose is to study the effect of systematic application of various doses of mineral fertilizers on productivity, grain quality, value of spring barley productivity elements, determine an optimal doses of nitrogen, phosphorus and potassium in the arid conditions of the Middle Volga region. Improving nutrition with the use of fertilizers contributed to an increase in productivity values. The average yield was 0.18–0.76 t/ha. The use of maximum doses of nitrogen, phosphorus and potassium did not increase productivity in arid conditions. Nitrogen plays a leading role in increasing barley productivity. The agronomic effectiveness of fertilizers depended on the doses of active substances. An increase was 2.1–5.8 kg of barley grain per 1 kg of active substances. The most stable increase was observed when applying N 60 Р 0-60 К 0-30 . Rational doses are as follows: nitrogen 60–90 kg a.e./ha when applying P 60 K 30 , phosphorus 30–60 kg a.e./ha when applying N 60 K 30 , potassium 30 kg a.e./ha when applying N 60 Р 60 . The best option is N 60 Р 0-60 К 0-30 .
