Abstract

In order to study the effects of planting date on growth characteristics of barley cultivars, a field experiment was carried out at the Agricultural Research Station of Islamic Azad University-Isfahan branch (2011-2012) as a split plot experiment in randomized complete blocks design with three replications. Various planting dates (October 23rd, November 6th, and November 24th) were main plots whereas three cultivars (Nosrat, No. 4, Shooriand Fajr 30) were subplots. To evaluate the growth process, samplings were done every two weeks. According to results, total dry matter and leaf area index were decreased by late planting. Second planting date had the highest Crop growth rate and net assimilation rate. Maximums of total dry weight, leaf area index and Crop growth rate were belonging to Nosrat cultivar. Fajr 30 had less final decrease in leaf area index, total dry matter and Crop growth rate than other cultivars for the first and second planting dates. Nosrat and Fajr 30 cultivars had the highest net assimilation rate. The highest amount of stem lodging was observed in first sowing date and Nosrat cultivar. The highest grain yield was obtained from second planting date and Fajr30 cultivar. On the whole, planting Fajr30 cultivar at November 6th can be recommended for seed production in regions similar to this study.
