Field experiment was conducted during 2000 at Malakandher Research Farm, NWFP Agricultural University, Peshawar, Pakistan to study yield and yield components of different cultivars of maize as affected by various combinations of NP. Statistical analysis of the data revealed that grain yield, biological yield and stover yield was significantly affected by different varieties and fertilizer (NP) levels. Similarly, interaction between varieties and NP had a significant effect on grain yield, biological and yield and stover yield. Variety "Azam produced maximum number of grains cob-1, number of cobs plant-1, harvest index, stover yield grain yield and biological yield when compared to other varieties. When the effect of different levels of NP was taken into an account, it was revealed that plots treated with NP levels of 120: 90 Kg, NP ha-1 produced maximum, number of grains cob-1, number of cobs plant-1, Harvest index, stover yield grain yield and biological yield.
