TanveerA. Adil ChoudhryM. AminM.M.Z. MurtazaG. 4199924Response of two mungbean cultivars namely NM-54 and NM-92 to nitrogen levels of 0, 20, 40 and 60 kg ha1 was studied under field conditions. The cultivar NM-92 gave significantly higher seed yield than cultivar NM-54 due to higher number of pod bearing branches plant-1, number of pods plant1 and number of seeds pod1. Yield and yield components were also influenced significantly by nitrogen levels. The application of nitrogen at the rate of 60 kg ha1 significantly depressed the seed yield and yield components except number of pods plant which were statistically similar with nitrogen application of 40 kg ha1. Maximum increase in seed yield, recorded at 40 kg N ha1, was about 31 percent higher of control. The increase in seed yield with nitrogen application was related to higher number of pods plant1, number of seeds pod1 and 1000-grain weight. Protein contents were also influenced significantly by nitrogen application, being maximum (26.18%) at nitrogen level of 40 kg ha1. Nitrogen application at the rate of 40 kg ha seems to be the optimum level for harvesting higher yield of mungbean.]]>Ahmed, A., M. Iqbal, M. Javaid and Z.
