Productivity of sorghum crops in the southern chernozems of the Orenburg region

Abstract

Both the crop production and animal husbandry industries are developed in the Orenburg region. For the normal development of the livestock industry, it is necessary to create a stable feed base. The Orenburg region is characterized by a sharply continental climate with frequent droughts. Therefore, it is necessary to select drought-resistant forage crops. Such crops include sorghum crops. In our research, hybrids and varieties of sugar sorghum, sorghum-sudangrass hybrid, Sudan grass for green fodder, as well as hybrids of grain sorghum for grain have been studied. It was revealed that in severe drought, the most productive for green fodder is sugar sorghum of the Silosnoye 88 variety, in medium drought – sorghum-sudangrass hybrid Boyarin. In terms of grain sorghum hybrids, the Willy hybrid turned out to be the best in terms of productivity.
