Formation of the harvest of cereal and legumine agrocenoses on the territory of the Shebalinsky district

   The Altai Republic has a livestock sector, so the main task of crop production is to increase the production of high-quality and balanced feed. This article presents the results of research on the productivity and nutritional value of cereal and legume agrocenoses cultivated in the mid-mountain zone of the Altai Republic. Field experiments were conducted on the basis of the “Experimental station “AESKH”, the village of Cherga in the Shebalinsky subzone of the mid-mountain zone of the Altai Republic. Annual cereal and legume forage crops were studied in single-species and mixed crops. The results of research on the growth, development, yield and nutritional value of cereal and legume agrocenoses over two years are presented. The following types and varieties were used in the test: from cereals – oats Argument, Sudanka Prialeiskaya 7; from legumes – Altai universal peas and Siberian clover 2. The ratio of grass mixtures during sowing: 70 % of cereals and 30 % of legumes. The most productive options were oats + peas and oats + sweet clover. These agrocenoses formed an average of 12.5 to 22.0 t/ha of green mass in two years. According to the availability of digestible protein for 1 feed unit, the best result was shown by the options: oats + donnik (124 g), sudanka + donnik (130 g). The following options have a great advantage in terms of energy exchange and feed units: sudanka + peas, oats + sweet clover. All the agrocenoses studied by us correspond to the zootechnical norm of providing 1 feed unit with digestible protein 105-115 g. Legumes in single–species sowing are sufficiently highly provided with digestible protein and, when added to the cereal component, provide a higher-quality feed balanced in protein.
