Abstract

This study was carried out to determine the effect of different application rates of nitrogen on yield, yield components and quality of cotton (Gossypium hirsutum) in the arid lands of Iran. Nitrogen (N) was applied to the soil at rates of 0, 100, 200 and 300 kg ha . Statistical results of study showed that N application 1 significantly (P 0.05) increased boll number, boll weight, seed cotton weight of boll, seed cotton yield and lint yield. Moreover, N concentration of leaf blade was affected by N application rate and increased significantly. Results of study also showed that the highest seed cotton yield was obtained in case of 200 kg ha N 1
