Peanut



Peanut, also known as groundnut (Arachis hypogaea), is a crop of global importance. It is widely grown in the tropics and subtropics, being important to both smallholder and large commercial producers. It is classified as both a grain legume, and, because of its high oil content, an oil crop. World annual production is about 46 million tonnes per year. Peanut pods develop under the ground, which is very unusual among crop plants.
