Effect of N:P Levels on the Growth and Yield Parameters of Soybean

M. Qasim, Asif Khan, Himayatullah and Rahim Din


It was observed that differences in plant height, number of branches plant -1, number of pods plant -1, 1000 grain weight and seed yield ha -1 were significant due to N:P levels. Treatments having N:P @ 75:100 kg ha -1 gave significantly higher grain yield and this increment was associated with all other parameters. However, further increase in N:P upto 100:150 kg ha -1 increased plant height and number of branches plant -1, but this increase was statistically non-significant. It could be concluded that for getting better soybean yield, N:P may be applied @ 75:100 kg ha -1 under the prevailing agro-climatic conditions of Peshawar.
