Different physiological responses to water stress were observed among selected cowpea and mungbean varieties. The mungbeans generally maintained higher leaf water potential and greater transpiration rate. The cowpeas exhibited higher stomatal resistance. Canopy temperature was comparable among varieties. Flowering and maturity of all cowpea and mungbean varieties were delayed at the driest regime but the delay was greater for the cowpea varieties. Seed yields were significantly reduced at the two regimes farthest from the line source. The mungbeans produced greater seed yields than the cowpeas but the seed yield of mungbeans were more susceptible to water stress. All season produced comparable yields at the three moisture regimes thus is suited for planting at pre-upland rice conditions. The mungbean entries had comparable yields at all moisture regimes but IPB M79-9-82 had the lowest drought susceptibility index. Among the yield components, pod density was greatly reduced by water stress but the number of seeds per pod, seed weight and pod length were not adversely affected.
