Groundnut is the most important oilseed crop in Tamil Nadu, accounting for about 50% of the state’s oilseed production. It is grown in all districts of the state, but the major producing districts are Madurai, Coimbatore, Tiruchirappalli, and Salem. The crop is grown both as a kharif and rabi crop, with the kharif crop accounting for about 70% of the total production.
Groundnut is a legume crop that is grown for its edible seeds. The seeds are a good source of protein, oil, and fiber. They are also a good source of vitamins and minerals, including vitamin E, magnesium, and phosphorus.
Groundnut is a relatively drought-tolerant crop, but it does require a well-drained soil. The crop is usually grown in rotation with other crops, such as rice, cotton, and sugarcane.
The main pests of groundnut are the groundnut bruchid, the groundnut leaf miner, and the groundnut aphid. The main diseases of groundnut are the groundnut rust, the groundnut wilt, and the groundnut mosaic virus.
Groundnut is harvested when the pods are mature and dry. The pods are threshed to remove the seeds, which are then dried and stored. The seeds can be used fresh or roasted, and they can also be processed to produce oil, flour, and meal.
