The crops listed—Groundnut, Sesamum, and Pearl millet—are predominantly rainfed, meaning they rely primarily on monsoonal rainfall for their water supply during the growing season. This characteristic is particularly significant in India, where these crops are often cultivated in arid and semi-arid regions, which experience variable rainfall patterns. Understanding the reliance of these crops on rainfed conditions is essential for comprehending agricultural sustainability, food security, and climate resilience in the context of Indian agriculture, topics frequently emphasized in UPSC GS Paper I.
