It is used for making margarine, medical emulsions, and soaps. While the oil of groundnut is used for cooking, its oil cake is used as cattle feed. The nuts are also eaten raw, roasted, salted, and sweetened. Climatic Conditions for Groundnut Cultivation, Soil needed, Methods and Distribution are discussed below
