Summary

Time of planting was found to significantly influence insect damage, quality of harvest and yield of cowpea in southern Nigeria. The greatest insect damage occurred on the August planting. Maruca testulalis was the most serious pest on cowpea whilst thrips were the least. Dry grain yield was higher in the early season plantings but quality of harvested crop was better in the late season plantings. These observations were also influenced by cultivar differences.
