Abstract

Barley is cultivated for food, technical and feed purposes. Barley grain is used for barley flour, pearl barley and a number of products, from which are prepared for our nutrition. In addition, it is used for the preparation of coffee substitutes, in the alcohol and brewing industries, has high feed qualities and is widely used as a concentrated feed for all types of farm animals, especially pigs. The results of studies showed that the dynamics of plant density and root rot damage were more influenced by planting rates, less than the estimated dose of fertilizers. The best nutritional regime and the maximum barley productivity (4.06 tons per hectare) with good grain quality indicators were obtained against the calculated nutritional background (4.0 tons per hectare) with a sowing rate of 5 mln. germinating seeds per 1 ha. The two-factor field experience with serial distribution of plots was laid on leached chernozem in LLC AF “Zay” of Zainsky district of the Republic of Tatarstan in 2013-2015. The purpose of the research was to study the biological characteristics of the variety and soil and climatic conditions for yield and quality indicators of barley grain. The objectives of our research were: to determine the effect of the seeding rate on the density of the stalk, damage to plants by root rot, the dynamics of plant nutrients, weediness of crops, yield and quality of barley grain. In the course of our studies, we found that the minimum value of barley grain quality indicators was observed against the background without fertilizers when sowing 5.5 million units per hectare: nature was 620 g/l, filmy 9.4%, germination 96.8%, the protein content of 11.9% and the extractivity of 77.0%, the maximum against this background was observed when sowing 4.0 million units per hectare. The barley grain quality indicators, grown against a calculated nutritional background, may well correspond to the brewing industry. The formation dynamics of plant densities and affection with their root rot had a greater influence on planting rates, and less calculated doses of fertilizers.
