Abstract
This research determined the effect of planting date and pruning on the productivity of five pigeon pea cultivars planted under humid tropical conditions at Corozal and under wet-dry tropical conditions at Santa Isabel (under irrigation). With proper management, two successful heavy crops of pigeon peas were obtained from December to May from plots planted March, June and September, with average total yield of 10,800 kg of mature pods/ha. At Corozal, highest yields were obtained from the September planting with the 2-B-Bushy cultivar, 12,900 kg of mature-green pods/ha. At Santa Isabel, with irrigation, pigeon peas yielded about 25% more than at Corozal, and determinate line 147 produced the highest yields, 16,195 kg of mature-green pods/ha. Pruning the pigeon pea bushes after harvesting the first crop decreased yields of the following crop at both locations, at all planting dates and in all cultivars.
