Effect of Growth Stage Moisture Stress on Common Bean (Phaseolus Vulgaris L.) Yield and Water Productivity at Jimma, Ethiopia

Water stress is a major crop production constraint for common bean (Phaseolus vulgaris L.). This study investigated the response of common bean (Phaseolus vulgaris L.) to moisture stress at different growth stages for yield and water productivity under sub-humid climate conditions over a three-year period. A field experiment was conducted at Jimma Agricultural Research. A randomized complete block design with three replications was used. fifteen treatments which combined and imposed at four growth stages were used. The combined result indicated that there were a significant variation among treatments for yield, above ground dry biomass and water productivity. The yield of common bean was significantly affected due to moisture stress imposed at different growth stages.
