摘要：Two field experiments were carried out at the Agricultural Farm of the Faculty of Agriculture, University of Khartoum to study the effect of the insecticide Metasystox on cottonseed quality of two local cultivars, Barakat-90 and Barac-67. Three levels of concentrations of this insecticide were applied on field grown cotton. Oil, protein, phytic acid , and minerals content of cottonseeds were determined. The results showed significant increase in cottonseed oil of Barakat-90 and Barac-67, as influenced by different levels of treatments. Protein content increased significantly in cottonseeds of both cultivars. In contrast, the results of phytic acid , showed no significant difference in Barakat-90 cultivar. However, significant reduction was observed in Barac-67 cultivar. The value of mineral content of both cultivars have no consistent pattern of change.
