Peanut is a small annual dicotyledon herb growing up to a foot above the ground. It is thought to have originated in the Central Americas and from where it spread to rest of the world through Spanish explorers. Today, it is one of the widely cultivated oilseeds and established principal commercial crop in China, India, African nations, and the United States of America. Peanut plant takes approximately 120 to 150 days to produce the crop after sowing its seed. The process of peanut development is quite interesting! Its yellow flowers, after self-pollination, develop into "ovaries" called pedicels, which elongate rapidly to turn downward to bury several inches deep underground, from where the fruits develop into peanut pods we know. To harvest, the entire plant including roots dug out of the soil. Each plant may hold 10-150 fruit pods. The pods have a thick, wrinkled outer shell with 2-3 constrictions as in bean pods. Each peanut kernel is covered with a papery thin, brown layer and can be split into two halves as in any other legumes
