Abstract
Groundnut, Arachis hypogaea (L.), is an important oilseed crop and is the
primary source of vegetable oil in India. It is popularly known as peanut. It is also called
wondernut, earthnut and monkey nut. It is native to South America from where it spread
throughout the world. It was introduced to India around 16th century by the Portuguese.
(Hegde, 2005) Groundnut seed has high protein (25-28%), which is of high biological
value and oil content (43-55%) (Naeem-Ud-Din et al., 2009). It contains more protein
than meat and about two and half times more than in eggs, and far more than any other
vegetable food except yeast (Thakur et al., 2013).
Groundnut is one of the world`s most popular and universal crop, cultivated in
more than 100 countries on six continents. China and India are the largest producers of
groundnut. Groundnut is the largest source of edible oil in India and constitutes roughly
about 50% of the total oilseeds production. Among the major groundnut growing states
of India, there has been consistent increase in area under cultivation in Andhra Pradesh,
Tamil Nadu, and Karnataka. (Shinde et al., 2010). In India the crop is cultivated in
kharif and rabi with an area of 5.27 M ha with a production of 9.72 M t and productivity
of 1750 kg ha-1
during 2013-2014 (Department of Agriculture and Cooperation,
Ministry of Agriculture, Government of India, 2014). In A. P., during 2015-16
groundnut occupied an area of 0.09 M ha with a production of 0.20 M t and productivity
of 2214 kg ha-1
(Agriculture Action Plan, 2015-16).
