Aiming to evaluate the growth and productive capacity of different sesame genotypes, submitted to irrigation depths, an experiment was conducted at the Experimental Station of Embrapa, in Barbalha, CE. Five depths of irrigation and three genotypes of sesame were studied. These combined factors resulted in 15 treatments. The experiment was arranged in strips with 4 replications, resulting in 60 experimental units. Destructive growth analysis was performed, with samplings at 15 days interval to estimate leaf area and biomass. The growth variables were studied in 10 plants in each plot. At the end of the cycle, the production and its components were evaluated. The highest values of yield components were obtained with the water depth of 1026.50 mm. The growth of genotypes was affected by different irrigation depths, with higher growth of BRS Seda, in the higher availability of water, and in the lowest availability the genotype 27561-ELAG09 was the best. The highest levels of oil and protein were obtained in higher water availability.
