Which state is the leading producer of groundnut in india?

Hint: The peanut, also known as the groundnut, goober, pindar, or monkey nut, is a legume crop farmed primarily for its edible seeds and is categorised as Arachis hypogaea. It is commonly grown in the tropics and subtropics, and it is valuable to both small and large commercial producers.

Complete answer:
Peanuts have a flavour and nutritional profile comparable to "tree nuts" such as walnuts and almonds, and as a culinary nut, they are frequently eaten in similar ways in Western cuisines. A nut is defined botanically as "a fruit whose ovary wall hardens at maturity". According to this definition, the peanut is not a nut. Peanuts, on the other hand, are commonly referred to as "nuts" in culinary circles and in everyday English.
Gujarat, Andhra Pradesh, Tamil Nadu, Karnataka, Maharashtra, and Rajasthan are the major groundnut producing states. Gujarat is the leading producer, accounting for 40% of total groundnut production in the country. According to the crop coverage statistics for India as a whole,
According to the Government of India, as of September 20th, 2018, groundnut has been sown in around 40.13 lakh hectares, which was 3.25 percent less than the similar period last year (41.48 lakh ha). Gujarat has sown 14.67 lakh hectares of it, followed by Andhra Pradesh (6.61 lakh ha) and Rajasthan (6.07 lakh ha).

Therefore, Gujrat is the largest producer of groundnut.

The peanut is a member of the Fabaceae (or Leguminosae) plant family, also known as the legume, bean, or pea family. Peanuts, like most other legumes, have symbiotic nitrogen-fixing bacteria in their root nodules. Because of their nitrogen-fixing ability, peanuts require less nitrogen-containing fertilizers and improve soil fertility, making them useful in crop rotations.

Note:
It is classed as a grain legume as well as an oil crop due to its high oil content. In 2016, the world's yearly production of shelled peanuts was 44 million tonnes, with China accounting for $38\%$ of the total.
