Abstract
Whole, one-holed and two-holed seed of one cowpea cultivar and two dry bean cultivars was subjected to the standard warm germination test. Whole and two-holed iced of another cowpea cultivar, untreated and treated with insecticide was planted to evaluate field performance. The laboratory germination test recorded normal seedlings, abnormal seedlings and dead seeds. In the field trial, yield and yield components and plant stands were recorded. In aU cases the relative seed weight differences between. the different seed categories were determined. Bruchid damage resulting in one and two holes per seed resulted in significant decreases in seed weight and germination percentage. There was a high, positive correlation between seed weight and percentage normal seedlings. Bruchid-damaged cowpea seed (two-holes) compensated for its low stands by increasing the number of pods per plant and .did not have significant differences in yield with whole seeds. Insecticide application to the infested cowpea seed was of no effect to crop Performance
