Abstract

In order to study the effect of plant densities on YIELD and YIELD components in four cultivars of bread WHEAT, a field experiment was conducted in College of Agriculture, Shahid Chamran University during 1997-98 year. Experiment was a factorial design based on RCB with four replications. Factors were cultivars (Falat, Atrak, Vee/nac and Maroon) and plant densities (200, 300, 400, 500 and 600 plant/m2). Results indicated that the effects of cultivar and PLANT DENSITY were significant in 1% level on the biological, grain and straw YIELD and HARVEST INDEX(except effect of PLANT DENSITY on straw YIELD), but their interaction were not significant. Atrak and Maroon with 5728.8 and 4315.5 kg/ha had the highest and lowest grain YIELD, respectiveley. Biological YIELD increased By increasing PLANT DENSITY. The highest grain YIELD for Falat and Atrak cultivars were obtained at 500 plants/m2 , but in Vee/nac and Maroon at 600 plants/m2 gave the highest grain YIELD. The effects of cultivar and PLANT DENSITY were significant on number of spikes/m2, spikelets/spike, no. of grains/spike and grain weight (at 1% Level). Vee/noc had the highest number of spikes/m2 but Atrak had the highest number of spikelets/spike and no. of grains/spike. Maroon had the highest 1000 grain weight among tested cultivars. Number of spikes/m2 was the only YIELD component which was increased by increasing PLANT DENSITY.
