A field experiment was conducted during the 2017-2018 and 2018-2019 cultivation seasons in Sheikh Mohamed location, which is about 25 km to the north of Mosul city in order to evaluate yield, yield components and quality of three sesame genotypes (Promo, Uzbekistan and Kenana), three rates of phosphorus fertilizer (0, 50 and 100 kg P2O5) and three plant densities (41666, 55555 and 83333 plant.ha-1). The trials were conducted according to Complete randomize block design with split - split plot with three replications. Analysis showed that yield and most of the yield components and quality were affected by fertilizers, genotypes, and plant density. The addition of 100 kg.ha-1 of phosphorus treatment gave higher seed and oil yield than that of control and 50 kg.ha-1 application. Genotypic difference was observed in all traits. Uzbekistan genotype gave a high level for plant height, number of primary branches, number of capsule.plants-1, number of seeds.capsule-1, 1000 seeds weight, seed yield, total seed yield, seed oil content and oil yield in the two growing seasons. Plant densities of 41666 plant.hectar-1gave the highest number of primary branches, number of capsule per plants-1, number of seeds.capsule-1 and 1000 seeds weight in the two growing seasons 2017-2018 and 2018-2019.
