Abstract

A field experiment was conducted at Mountain Agricultural Research Centre, district Gilgit, Northern Area of Pakistan to evaluate the  effect of different N  levels (0, 45, 90, and 135kg ha-1) on different varieties of maize (Pahari, Azam, Jalal). This experiment was laid out in Randomized Complete Block Design  with three replications while N was applied in  two split doses half each at sowing and at first irrigation . The results indicated the improved performance of all parameters (plant height, grain weight, number of rows cob-1, number of grains cob-1 and Grain Yield (kg ha-1) by increasing the amount of nitrogen fertilizer from control to 135 kg N ha-1. The application of 90 kg ha-1 seems sufficient to acquire the optimum yield. At this nitrogen level maximum number of grains Cob-1(527.67) and  maximum thousand grain mass (374.67) were recorded in Azam, maximum plant height was recorded in Pahari (216.67), maximum grain yield kg ha-1 and maximum number of rows  Cob-1 were recorded in Azam. Which were 3740.0 and 10.00.
