Abstarct: In order to study of the effect of priming on the quality and quantity of cowpea under drought stress an experiment was carried out in as split-plot baxsed on randomized complete block design with 3 replications. Treatments consisted of three levels of drought stress on an irrigation 7, 10 and 14 days as the main factor and priming the four levels of priming, hormonal priming with abscisic acid, soaking for ten hours in a solution of distilled water with 100 ppm of hormone abscisic acid at a ratio of 50% by weight of seeds at 25 ° C, hormone priming with gibberellic acid, soaking for ten hours in distilled water with 100 ppm of hormone gibberellic acid at a ratio of 50% by weight of seed 25 ° C and hydro priming soaking in distilled water for ten hours with about 50% by weight of seed at 25 ° C were considered as sub plots. Priming before planting seeds was done. Stress treatment plant after full deployment began and continued until the end of the growing season. In this experiment, drought stress reduced plant height, shoot dry weight, leaf relative water content, chlorophyll a and grain yield. Priming increased stem diameter. Hormone priming and priming with gibberellic acid increased the number of branches. The priming treatments with gibberellic acid increased stability of the plasma membrane. The use of priming and drought stress resulted in greater stability of the plasma membrane. Priming performed particularly gibberellic acid treatment increased leaf dry weight.
