Abstract

In order to evaluate the relantionships between GRAIN YIELD, yield components and other attributes relating to GRAIN YIELD, three BARLEY cultivars (Mahor, Ezeh and Regional Dopar) effected by five planting densities of ( 100, 200, 300, 400 and 500 seeds/m2), a factorial design with three replications in RCBD was carried out at KhorrmAbad agricultural research station in 2006-2007 cropping year. The results showed significant difference among cultivars in regards to morphological characteristics, yield components and GRAIN YIELD. While the highest number of grains per spike, leaf area index, harvest index, and the highest plant height belonged Ezeh cultivars. Increasing PLANT DENSITY reduced plant height and spike length and increased biological yield and number of spikes per square meter, significantly. But it had no significant affect on GRAIN YIELD, due to the self-regulatory mode by changing the tiller grinding grains such as BARLEY. Mahor cultivar with an average GRAIN YIELD of 5617 Kg grain per hectare and 15680 Kg of biomass in hectare due to greater number of spikes per square meter (528 spikes) was better than other cultivars. GRAIN YIELD had positive and significant CORRELATION with the number of spikes per square meter (r= 0.47**) but was negatively correlated with leaf area index and 1000 grain weight. Regarding to the obtained results, density of 300 grain m2 can be recommended for BARLEY cultivars in dry land conditions.
