Crop production involves growing crops on a large scale. There are two types of crops - kharif crops grown during the rainy season like rice and maize, and rabi crops grown during winter like wheat and gram. The basic practices of crop production are preparing the soil, sowing seeds, adding manure and fertilizers, irrigating, protecting from weeds, harvesting, and storing. Irrigation involves supplying water to crops at different intervals depending on the crop, soil, and season. Traditional irrigation methods have been replaced by modern techniques.
