Red gram, also known as pigeon pea (Cajanus cajan), is a leguminous crop widely cultivated in tropical and subtropical regions. It is valued for its high protein content and is a staple in many parts of Asia, Africa, and Latin America. The plant grows as a small shrub and produces pods containing seeds that are rich in proteins, carbohydrates, and essential amino acids. Additionally, red gram improves soil fertility through nitrogen fixation, making it beneficial for crop rotation and intercropping systems.
