Trinidad and Tobago currently imports much of its grain legumes. Pigeon peas are the most commonly grown grain legume. Considerable work has gone into the development of dwarf deterainate cultivars of pigeon peas in the Regional Research Centre of the University of the West Indies. A new system of production has evolved based on high density plantings of these cultivars in December of January, so that they come to bearing within 110 days, and give high yields of green pods from a single harvesting. With a yield of 4000 lb/ac., a gross income of $680/ac could be achieved, but hand-harvesting costs could be high. Work is in progress on a mechanical harvester. This system of production should ensure increased supplies of fresh peas for processors, lead to intensified land use (since the crop occupies the land far less time than traditional pigeon pea crops), and could lead to savings in imports and export earnings.
