A field trial aimed at evaluating the effect of drought on the yield of different cowpea cultivars and their response to time of planting was conducted at the research farm of the International Institute of Tropical Agriculture (IITA) Minjibir, longitude 8 0 37 ' E and latitude12 0 11 ' N during the rainy season of 2010. The results shows that in all the parameters measured, which include fodder yield, days to 50% flowering, 95% maturity ratio, and grain yield, and sowing dates, had some significant effect, and it therefore, assumed that drought and terminal stress does not only affect the grain yield, but also the fodder production in all the cultivars tested.
