Answer
Peanuts were promoted by George Washington Carver as an alternative to cotton, which was heavily relied upon in the South. Carver recognized the soil-depleting effects of cotton cultivation and sought to introduce more sustainable crops. Peanuts, being legumes, have the ability to fix nitrogen in the soil, improving its fertility. Additionally, peanuts are a versatile crop, providing both food and oil, making them a valuable addition to agricultural systems.
