Pigeon pea is a nitrogen-fixing, perennial shrub, growing to 4 m in height, that produces green or dry seed in seasonally dry climates. Pigeon peas are adaptable to many soil types and are used as a dry pea, green vegetable, fodder, fuelwood, green manure or cover crop.

‘Caqui’ is a long duration, indeterminate pigeon pea variety that produces abundant pods of creamy, white-colored seeds. As well as human consumption it is used for intercropping, green manure and fodder.
