The article substantiates the expediency of using sorghum grain (seeds) as a substitute for corn in feed for poultry. The aim of the study was to develop a recipe and technology for the preparation of compound feed of increased nutritional value for birds using sorghum grain subjected to IR - processing. Examples of its impact on grain quality and its biological value are considered. The physical principles of operation of this technology and the properties of the applied method are analyzed. It was found that protein digestibility and attack by its enzymes increased from 82.3 to 89.8%. The results of a comparative zootechnical assessment of the quality of feed without sorghum and with the replacement of 47.0% of corn with this raw material are presented. The economic efficiency from the use of the proposed composition of feed for chickens and the profitability of its production have been established.

In a hot climate in the Khatlon region of the Republic of Tajikistan examined the nature of the formation of production figures collectible varieties of potatoes. It is established that the varieties of potatoes Nilufar Tajikistan, Faizabad (st.) Rasht and give 100% germination within 25 days from planting, while other varieties sprout during 27-29 days from planting. In these conditions the greatest number of stems observed in the cultivars Muhabbat, Tojikiston, F1 (Nilufar x Clone-2) and Nilufar (4...5 PCs./plant). Varieties of potatoes Muhabbat and Nilufar exceed other varieties on the grounds of: the mass of stems in a 2.7 and 7 times the mass of roots in 2.5...3 times the mass of tubers at 6.0...6.75 times and the total biomass in 4...5 times. Adaptive reactions of potato cultivars in a hot climate Khuroson district is strongly associated with genetic features of studied varieties of potatoes. In hot climates Khuroson district, the most productive was the cultivar Muhabbat, Nilufar, Tojikiston, Faizabad (st.), which have a mass of tubers from 235 to 300 g/plant, and total biomass of the most productive varieties are varieties Muhabbat, Nilufar Tajikistan, which are from 400 to 500 g/plant (almost 2 to 3 times more than other varieties of potatoes). Therefore, varieties Muhabbat, Nilufar Tajikistan, and are more heat-resistant varieties and these can be rec-ommended in the future for breeding in hot climates Khuroson district of Khatlon region of Tajikistan.
