Sorghum is an important cereal crop which is grown globally for food and feed purposes. It is most widely grown in the semi-arid tropics where water availability is limited and frequently subjected to drought. About 100 countries grow sorghum, of which 66 cultivate it over more than 1000 ha or produce more than 1000 tons. India has the largest sorghum area with 10.06 million ha. The second largest sorghum cultivating country is Nigeria, followed by Sudan, USA and Nigeria.
