Abstract:Nutrient management is an imperative agronomic factor for enhancing crop yield. Thus, an experiment was conducted on a sandy loam soil at the Central Cotton Research Institute, Multan, Pakistan, to evaluate the response of applied nitrogen through different application methods. Foliar application of nitrogen was done as; 2 and 4 urea sprays with one control treatment while in another method basal application was done with treatments: control, 40, 70 and 100 kg N ha-1 against CIM-496 cotton cultivar. Comparison of both methods exhibited that significant increase in plant height, number of main stem nodes, total number of fruits, total open fruits m-2, boll weight, seed cotton, cotton seed and lint yields were observed with 100 kg N ha-1 or with 4 urea sprays. Similarly, various important plant physiological indices like leaf area index, crop growth rate, net assimilation rate and dry biomass production were significantly improved with 100 kg N ha-1 as with 4 urea sprays. However, as concerned with the fibre quality parameters, fibre length, strength and maturity percentage were improved with basal application as compared to foliar application method. Four times foliar application of urea demonstrated similar results as with basal application of 100 kg nitrogen/ha.
