Manual cowpea thresher was previously designed and constructed. Its performance evaluation is now reported. Performance test was replicated five times and averages of each trial were taken (50, 100, 150, 200 and 250) kg of two cowpea varieties: indigenous brown (Variety A) and IT97K-499- (SAMPEA -10) white (Variety B). Parameters considered were: Threshing efficiency (Te), Seed damage (Sd) and Mechanical efficiency (Me). The results show that Te, Sd and Me were (91, 6 and 44%), respectively. Issues on cowpea threshing and its improvement were discussed. © 2011 Academic Journals.
