Delicious, crunchy, and nutty peanuts are one of the popular oil seeds known to humankind since ancient times. The nuts are enriched with many noteworthy health-benefiting nutrients that are essential for optimum health. They are actually legumes but have almost all the qualities that true nuts like almonds have.
Botanically, the nuts are small size fruit pods of plant belonging to the Fabaceae family of the genus, Arachis. Some of the common names are groundnut, earthnuts, etc.
Peanut is a small annual 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, the nuts are widely cultivated oil seeds and has established as prime commercial crop in China, India, African nations, and the United States of America.
After the seedling, the plant takes approximately 120 to 150 days to produce the crop. The process of peanut development is quite interesting! The yellow flowers, after self-pollination, develop in to "ovaries," called pedicels, which elongate rapidly to turn downward to bury several inches deep under the ground from where the fruits develop into peanut pods we know.
To harvest, the entire plant, including roots, is dug out from the soil. Each plant may bear 10-150 fruit pods. The pods have wrinkled shells that are constricted between pairs of the two to four seeds per pod. Each seed is covered with thin brown color cover and can be split into two equal halves as in any other legumes.
