One of the major regions in agricultural production in the Russian Federation is suhostepova area of the southern Urals. However, a sharply continental climate zone requires a constant search for ways to increase the efficiency of agriculture. Of great importance in the zonal plant growing dry steppe zone of the South Urals acquires a right selection of drought-resistant crops, which are able to generate high and stable yields. To number of such crops that can provide guaranteed high yields not only in the zone of dry steppes, but in semi-desert, with loss of250-300 mm of rainfall per year applies sorghum. Using active sun insolation and large resources of heat, sorghum can produce a stable harvest of grain, silage and green mass exceeding in the conditions of arid climate, productivity of the majority of field cultures in 2-3 times. The volume of the cultivation of grain and green mass sorghum do not meet the constantly growing demands in connection with insufficiently high yield. It is therefore necessary to seek ways to solve this problem in the development and application of new zonal elements of technology of cultivation of culture, which will help stabilize grain production and feed in the region to the arid southern Urals. In this regard, is very urgent to develop the basic methods of cultivation of sorghum in pure and mixed crops for feed purpose in conditions of dry steppe zone. The effectiveness of feeding silage from sugar sorghum, maize in pure form or in mixtures with amaranth in the ratio of 3:1 is studied on young growth of large horned livestock, cultivated in the meat.
