Abstract
An experiment to study the effect of different levels of nitrogen and phosphorus on performance of wheat (Triticum aestivum L.) was conducted at ITM University, Gwalior during Rabi season 2015 -2016.The combination of three nitrogen levels (50, 100 and 150kg ha-1) and three levels of phosphorus (40, 60 and 80 kg ha-1) were tested in Randomized Block Design with three replications. Significant improvement in plant height, number of tillers, number of leaves and yield attributes were recorded with increase in N application from 50 to 100 and 150 kg ha-1. Increase in levels of Phosphorus from 40 to 60 and 80 kg ha -1 has increased the leaf number per culm, tiller number, number of ear head m-2, spike length, grain number, grain, straw and biological yield. The maximum grain, straw and biological yield was recorded with the application of 150kg N ha-1 80 kg P2O5 ha-1 which was followed by 150 kg N ha-1 60 kg P2O5 ha-1 while, the minimum yield was observed in 50 kg Nha-1 40 kg P2O5 ha-1.
