Purple flower pea are a valuable fodder and raw materials crop for animal husbandry Central Black Earth region of Russia

The active development of animal husbandry requires production high-protein and cost-effective crops for the feed base from the feed industry. Purple-flowers peas are of great value in this regard. The article studied the productivity and quality of modern varieties of Purple-flowers peas compared with white-flowered varieties of peas and assessed the possibility of their use for fodder purposes in the Central Black Earth region of Russia. It has been established that, compared with white-flowered varieties of peas, purple-flowered varieties form a high grain yield with high grain quality: the protein content in the grain of hay varieties is 24.7%, grain varieties 24.1%. Purple-flowered varieties do not differ from white-flowered varieties in the content of inhibitors of animal and human pancreatic enzymes: trypsin 1.53-1.98 mg/g, chymotrypsin 3.86-4.14 mg/g (in white-flowered varieties 1.08 and 3.80 mg/g, respectively). Among the studied genotypes in the green mass, the maximum amount of protein was in the purple-flowered varieties of the cutting direction of use - 15.4%, 14.5% in the white-flowered varieties of peas, and 13.7% in the purple-flowered varieties of grain use. The active introduction of purple-flowered peas into production, due to their less demanding growing conditions, will provide the livestock industry with high-protein feed in the Central Black Earth region of Russia. These varieties can be used as a legume component in grain mixtures, for the preparation of animal feed and biotechnology. Purple-flowered peas of the cutting direction can be used as a legume component when used for green mass or as harvested fodder.
