Assessment of efficiency of elements of agro-technical spring barley in the conditions of the Middle Volga region

The article provides an economic and energy analysis and assessment of elements of agrotechnology of spring barley when using foliar processing of plants at various seeding rates. The aim of the research is to determine on the grade of spring barley Povolzhsky 22 the effectiveness of a single sheet processing with the Mival-Agro + Lignohumate + Zelenit N complex with seeding rates of 3, 4 and 5 million germinating grains per 1 ha, economic and energy assessment of the studied variants, clarification of their rationality of use. The results of the analyzes showed that the studied elements of the cultivation technology in all variants turned out to be economically and energetically favorable. Maximum efficiency indicators were observed when using the organic-mineral complex at seeding rates of 4 and 5 million / ha. At the same time, net income reached 6488 rubles / ha, and the level of profitability was 54.5%. When using the complex Mival-Agro + Lignohumate + Zelenit N, the yield of spring barley at all seeding rates increased by 0.18 - 0.35 t / ha, the level of profitability was 333-375%, net income was 906-1796 rub / ha.
