Any crop grown for food, either commercially or for individual use is called food crop. Grains like rice and wheat form an integral part of food crops. But there are other grains known as coarse grains like jowar, bajra, ragi (collectively called millets), maize and barley that also fall under the category of food crops. Following parts describe the climatic conditions required for the growth of jowar, bajra, and maize. a) Jowar – It is grown both as a Kharif and rabi crop and is the main food grain in the semi-arid and arid regions of central and southern India. Although it is mostly grown in areas with which are moist and hardly needs irrigation, it is a hardy drought-resistant crop. b) Bajra – Similar to jowar, bajra also grows well in dry and warm climate. c) Maize – This is a Kharif crop and grown under semi-arid conditions with a temperature range of 21 ºC to 27 ºC.
