Abstract
Within the framework of increasing the export potential of the Republic of Kazakhstan, the most 4 priority areas for the development of agriculture have been identified, among them it is important to diversify crop production. In this regard, in the near future, the crop production industry will continue to work on diversification, replacing part of the wheat area with more demanded crops (fodder and oilseeds), which is also important for reducing the dependence of crop productivity on weather conditions. According to the morphological characteristics of the genetic horizons of the profile and the agrochemical parameters of the arable layer of the soil of the experimental plots, they are characteristic for dry steppe zone 1 of Western Kazakhstan. The area of the plots during the cultivation of barley is 50 m 2 , the repetition is threefold, the arrangement of the plots is systematic. In the experiments the zoned barley variety “Donetskaya 8” was used. Seeding rate was used asrecommended for the dry-steppe zone of WKO. In the system of biologized agriculture, microbiological preparations and bioorganic fertilizers recommended and available on the market were used for the study of pre-seeding treatment of seed material and spraying during the growing season of barley. As a result of the study, an agroecological and bioenergy assessment was carried out for barley of the harvest of 2020, cultivated in biologized raw material conveyors for the production of concentrated feed, used in the diversification of crop production.Pre-seeding treatment and the use of biological products and biofertilizers during the growing season promotes the activation of a number of growth, physiological and biochemical processes of plants, which leads to an increase in barley yield. With the combined use of the biological product Biodux, biofungicide Orgamica S and biofertilizers Organit N, Organit P (biologized technology), the maximum indicators of productivity and feed, energy-protein value of feed barley were obtained.
