Abstract

In order to investigate the effects of different levels of NITROGEN rates YIELD and YIELD components of 3 WHEAT cultivars an experiment was conducted on Shahid Bahonar University of Kerman Research farm during 2002-2003. The experiment was carried out using split plot design in rhandomized complete block with three replications. NITROGEN rates were arranged as main plot in 3 levels (50, 100, and 150 kg/ha) and 3 WHEAT cultivars as subplots in 3 levels (Ghods, Roshan and a native cultivars Shahdad). YIELD, YIELD components, plant height, 1000 seeds weight, %seed protein, harvest index, biological YIELD and dry weight were investigated. Higher level of NITROGEN increased YIELD, seed weight, spikes/m2, dry weight in fertilized stage, seeds/spikelet, %seed protein and biological YIELD significantly. However harvest index decreased as NITROGEN increased. The effects of cultivars on all aspects were statistic significant. Ghods cultivar showed higher biological YIELD, seed YIELD and harvest index, but its plant hight, seed weight and % seed protin was lower. Shahdad cultivars had highest spikes I m2and Roshan had highest percent seed protein. Seed YIELD had negative correlation (r=-0.779) with % seed protin, but positive correlation with biological YIELD (r=0.874), dry weight (r=0.821) and harvest index (r=0741). It was concluded that 100kg of NITROGEN/ha, and Ghods cultivar had best results in this experiment in Kerman, but Roshan was the best in % seed protein.
