Horse Gram (Macrotyloma uniflorum): Complete Information

Horse Gram, scientifically known as Macrotyloma uniflorum, is an important leguminous crop belonging to the Fabaceae (Leguminosae) family. It is commonly known as Horse Gram in English and Madras Gram in some regions. Considered one of the oldest cultivated pulses in India, it has been an integral part of traditional Indian diets and medicinal practices for centuries.

Horse Gram is mainly cultivated in India, Sri Lanka, and several other South Asian countries. In India, it is widely grown in Karnataka, Tamil Nadu, Andhra Pradesh, Telangana, Maharashtra, Rajasthan, Gujarat, and Madhya Pradesh. One of its remarkable qualities is its ability to thrive in low-rainfall regions, dry climatic conditions, and relatively poor soils, making it a valuable crop for small and marginal farmers. Its seeds are generally small, oval to round in shape, and range in color from brown and reddish-brown to darker shades. Due to its rich nutritional profile and traditional medicinal value, Horse Gram is highly regarded as both a food and health-supporting crop.
