Response of two sorghum cultivars namely Hegari and JS-263 to different NP level s of 0-0, 50-0, 100-0, 50-50, 100-50 and 100- 100 kg ha-1 was studied under field conditions. The cultivar Hegari gave significantly higher green fodder and dry matter yield due to greater plant height, stem diameter and leaf area plant-1. The crude fiber percent and ash percent were also significantly higher for cultivars Hegari. A progressive increase in yield was observed with fertilizer application up to 100 kg N + 50 kg P2O5 ha-1 whereas, the quality parameters such as protein content, crude fiber and ash percent were significantly higher with NP application of 100 + 100 kg ha-1. The cultivars Hegari and fertilizer level of 100 kg N + 50 KG P2O5 ha-1 seems to be the best combination for harvesting higher fodder yield of sorghum under Faisalabad conditions.
