Abstract

It is impossible to organize proper feeding of farm animals without a detailed study of the composition of the nutritional content of feed. Legume-grass mixtures occupy one of main places in solving the problem of high-quality feed production. Since mixed crops of legumes and cereals retain high fodder quality of green mass due to high protein content in legumes. To meet the need for a high-quality feed base, it is necessary to look for ways to increase the yield of fodder crops. The use of innovative technologies is one of the components of modern crop production. The aim of the study was to study the methods of seed treatment in conjunction with the technology of mixed crops; it allows obtaining a green mass with the desired productive properties. Thus, the article presents the materials of a field study on the development of a highly productive green feed. The results of the study of combined and mixed crops on the nutritional value and productivity of annual forages of peas, millet, and barley using pre-sowing seed treatment with ultrafine particles of SiO2; MoO2; Fe3O4 and growth regulators AgroVerm and RibavExtra were obtained. As a result of the experiment, it was shown that the use of pre-sowing treatment of seeds with ultradispersed SiO2 particles in combined crops showed the maximum leaf surface area of 85.5 thousand m2/ha. By the time of harvesting, the safety of plants on variants with the use of SiO2; Fe3O4; MoO2 was 88.4%; 87.5%; 86.5% respectively. According to the collection of digestible protein, variant with the use of ultrafine particles SiO2 was 20% in both sowing methods. Low protein content was 16.1%; 16.4% in the control variants respectively. According to the content of feed units in 1 kg of dry matter, SiO2 variants prevail with 0.91. Thus, the research is the basis for possible studying of combined and mixed crops with the use of pre-sowing seed treatment with ultrafine particles. It allows obtaining high-quality feed.
