Obtaining high performance from barley needs to conform vegetative and reproductive growth stages to suitable weather conditions through suitable planting date. The present research carried out to study the effect of planting date on ecophysiological and morphological traits of ten lines and varieties of barley in different regions of Kermanshah by using split plats in randomized complete block design (RCBD) with three replications in the Research Farm of Islam Abad Gharb, Kermanshah province during cropping years 2011-2012. The treatments of planting date were consisting of 3levels October 7th, October 22th and November 6th as main factors and irrigated barley variety as sub – factors in 10 levels MBD–88–19, MBD–88, MBD–88–13, MBD–88–16, MBD–88–5, MBD–88–2 and D10 along with control genotypes of Nosrat, Yousof, and Nik. The results of analysis of variance (ANOVA) indicated that effects of planting date on seed performance, number of spikes per square meter, number of seed per spike, 1000-seed weight, biological performance and HI at the level of 1% probability were significant. The comparison of mean effect of planting date on economical performance showed that planting date of October 22th with 4736 kg per hectare has the most economical performance and November 6th with 4033 kg per hectare has the least performance.
