Abstract: Two Field experiments were carried out during the season 2002 / 2001 and 2001 / 2002 to investigate the effect of the insecticide Chlorpyrifos on cottonseed quality of Barakat-90 and Barac-67 cultivars. Three concentration levels of this insecticide were applied on field grown cotton. Oil, protein, minerals content were determined as well as the antinutritional factors content of cottonseeds. The results showed significant increase in cottonseed oil of Barakat-90 as influenced by different levels of treatments. While no significant difference was observed in Barac-67. Protein content increased significantly in cottonseeds of both cultivars. In contrast significant reduction in tannin content was observed for both cultivars, while no significant change was noticed in phytic acid for Barac-67 cultivar. Moreover the change in minerals of the cotton seeds showed no consistent pattern as influenced by different treatments.
