We studied the effect of chemical fertilizers including urea, sulfur-coated urea, ammonium sulphate, ammonium nitrate, diammonium phosphate, triple super phosphate, potassium sulphate and potassium chloride on incidence and severity of cotton seedling damping-off, verticillium wilt and alternaria leaf blight plant diseases, yield and yield components of cotton. We stablished two separately field experiments with plats arranged in a randomized complete block design with tree replications in Karkandeh cotton research station. Siokra or Varamin cotton cultivars were planted in each field experiment. Results showed that sensivity of cultivars and effect of fertilizer treatments on incidence and severity of cotton diseases were significantly different. Ammonium nitrate and urea showed the highest and the lowest seed-rot and seedling damping-off in soil. Ammonium nitrate and urea had the highest and lowest verticillim wilt persentage, respectively
