The groundnut belongs to the pea and bean family and is a leguma but is considered as nut because of its high nutrition value.The groundnut is the native of South America, where it has been cultivated for several countries. Peanut is the major oilseed of India.  Peanuts Production is highly weak to rainfall deviations and display huge fluctuation between years.
