Cajanus cajan, commonly known as pigeon pea, is a leguminous plant native to the Indian subcontinent. It is widely cultivated in tropical and subtropical regions for its edible seeds, which are rich in protein and essential nutrients. The plant typically grows to a height of 1 to 2 meters and produces yellow flowers that develop into pods containing several seeds. Pigeon pea is valued for its ability to improve soil fertility through nitrogen fixation, making it beneficial for crop rotation. It is also resilient to drought, allowing it to thrive in areas with limited water supply. The seeds can be consumed in various forms, including whole, split, or as flour.
