Description Objective: the aim is to investigate the intermittent drought stress and the season effects on agro-physiological parameters by assessing its impact on the leaf area index (LAI), leaf area, leaf dry weight and grain yield.

Methods and Results: Eighteen cowpea genotypes were tested in the field during cold and hot seasons. Two water treatments, well-watered (WW) and intermittent drought (WS), were imposed at vegetative and reproductive stages during three experiments. Our findings showed that the flowering date delayed up to 5 days in the cold season under water deficit. The LAI, leaf area and leaf dry weight were high under WW conditions. Under DH, grain yield decrease significantly (P
