Abstract

Corn is the most important feed crop, it provides high-energy feed, is indispensable for the production of high-quality silage. The introduction of mineral fertilizers, as well as their addition with trace elements, helps to improve the nutritional value of the feed, reduce the amount of fiber in the green mass and increase the content of raw protein. The article presents the results of research on the study of non-root processing of corn with complex fertilizers with trace elements at various levels of root nutrition. It was found that the greatest influence on the accumulation of protein substances in the maize biomass was exerted by mineral fertilizers, which contribute to the growth of raw protein, on average, by 1.24-1.35% compared to the non-maneuverable agrophone. There is a tendency to increase the protein content of biomass during foliar processing of corn plants. From the use of complex fertilizers with trace elements, the protein collection increased by 6.5-26.5 %. Depending on the agrophone and the complex fertilizers used, no significant changes in the content of raw fiber were detected. Non-root treatment with fertilizers with trace elements contributed to obtaining a greater yield of exchange energy, compared with the options without foliar treatment of crops, the increase was 3.4-15.5% on fertilized, and 13.5-24.5% on non − fertilized agricultural backgrounds. In all the studied agrophones, the advantage of non-root treatment with Cytovite was revealed in terms of the output of exchange energy. The use of ECOFUS is slightly inferior to it in terms of efficiency.
