Effect of Nitrogen Levels on the Growth and Yield of Spring Maize

The research entitled the "Effect of different nitrogen levels on growth and yield spring maize" was conducted in agriculture farm Lovely Professional University, Phagwara. Three doses used at concentrations from lowest to highest. Nitrogen are denoted as N1, N2 N3 viz 80kgN2ha-1, 120 kg N2ha-1and 160 N2ha-1 respectively. All compared with each other for measurement morphological parameters like plant height, number leaves dry weight accumulation. In parameters, grain yield, test weight, stover shelling percentage calculated. From experiment, it observed that highest results were found treatment dose Kg N/ha. per accumulation which is 160Kg percentage, also high application amount this research, best provided by N/ha, after moderate 120Kg N/ha least N1 80Kg
