An experiment was carried out to see the effect of different NP levels on maize hybrid "3335". The fertilizer levels were 90-90-90, 90-120-90, 90-150-90, 150-90-90, 150-120-90, 150-150-90, 210-90-90, 210-120-90, and 210-150-90 Kg ha-1 NPK including control having no fertilizer. The results revealed that maximum plant height (175.8 cm), number of cobs/plant (2.067), number of grains/cob (374.3), 1000-grain weight (226.5 9), Biological yield (15.42 t ha-1), and grain yield (48.08 t ha-1) was obtained by the application of NPK @ 210-120-90 kg ha-1. This level proved to be the optimum for maize crop under local conditions of Dera Ismail Khan.
