Abstract: Response of two mungbean cultivars namely NM-54 and NM-92 to phosphorus levels of 0, 50, 100 and 150 kg ha–1 was studied in field conditions during the autumn 1997. The growth and yield parameters like plant height, pods plant, seeds pant–1, 1000-seed weight and seed yield were influenced significantly by both phosphorus application and cultivars. However, number of pod bearing branches plant–1 were not influenced significantly by both cultivars and fertilizer levels. the maximum seed yield of 1095 kg ha–1 was obtained by the application of 100 kg P205 ha–1, The cultivar NM-54, yielding 1060.09 kg ha–1 seed proved to be superior than NM-92 (956.77 kg ha–1). The application of 100 kg P205 ha–1 was found to be the optimum level for obtaining higher yield of mungbean in Faisalabad conditions.
