Abstract
SUMMARY: The effects of populations of 33,000–250,000 plants/ha on growth and grain yield of two cowpea genotypes of bush growth habit was studied in lowland Papua New Guinea. The optimum economic seed rate seems to be 100,000 plants/ha; increasing the plant population decreased pods/plant and lateral branch development, but increased seed number/pod. Genotype UV.53 yielded more than UV.19 due to a combination of all three yield components, and a large dry weight. Growth analysis showed that treatment effects were mediated by differences in growth between 8 weeks and harvest.This publication has 2 references indexed in Scilit:
