摘要

The present study was carried out at the farms of Agricultural University Peshawar, KPK Pakistan during 2007. Experiments were conducted using RCB design with split plot arrangements, having four replications. Different wheat varieties viz., Uqab 2000, Saleem 2000 and Pirsabak 2004 while nitrogen levels (0, tap water, 90 kg ha-1in soil, 120 kg ha-1in soil, 150 kg ha-1in soil, 90 kg ha-1(2/3rdsoil + 1/3rdfoliar), 120 kg ha-1(2/3rdsoil + 1/3rdfoliar) and 150 kg ha-1(2/3rdsoil + 1/3rdfoliar) to subplots were used. Days to heading and maturity, plant height, productive and non productive tillers m-2, spike length, grains spike-1, 1000 grain weight and grain yield was significantly (p0.05) affected by different varieties, nitrogen levels and method of N application. Nitrogen concentration in straw and grain was significantly (p0.05) affected by different nitrogen levels and method of N application. Significantly higher grain yield was produced by Pirsabak 2004 when compared with other varieties. In case of N levels, maximum grain yield was produced by treatments fertilized with highest dose of foliar N.
