In order to evaluate effect of CCC application on growth, yield and agronomical indices at sowing dates on barely cultivars, the experiment was conducted as split factorial arrangement based on a randomized complete block design with three replications on 2009-2010 in Iran. The treatments comprised three sowing dates including; Nov 7., Nov 26. and Dec 11. As main plots, three cultivars including; Sahra, Productive and Line M and two CCC application; 0 and 2.8 Li/ha, as subplots. Results indicated the CCC application had 12 decreased plant height and stem length, but had increased ear length and total tiller per plan with 0.67 cm and 0.62 tillers relation to control, respectively. The highest and lowest of grain yield and harvest index were obtained by Sahar and Line M with 316.90 g.mG , 44.00 % and 244.40 g.mG and 39.86 %, respectively. The 12 2 2 interaction A ×B and N ×B had the highest and the lowest grain yield and harvest index with 345.80 g.mG and 2 1 3 3 2 235.00 g.mG2, respectively. There was high correlation between grain yield with plant height (0.74**) and harvest index (0.81**).
