Abstract: 

Sorghum is resistance to unsuitable environment condition such as low fertility of soil and drought. It can be cultivated in wide range of fields in south of Khouzestan. This study was conducted during 2002 and 2003, in order to determine suitable sowing date of grain sorghum cultivars on a clay soil in Khouzestan agricultural research center (Shawoor station), an experiment was carried out as split plots in randomized complete blokes with four replications. Main plots included five sowing date levels, starting from 21 May with 15 days intervals and subplots included three cultivars of grain sorghum (Payam, Kimiya and Sepideh). Evaluated indices were contained grain yield, fertility percentage, thousand kernel weight (T.K.W), raceme length, raceme width and number of spiklet per spike. The result showed that there were significant differences (P£0.01) among sowing dates and treatment interaction for grain yield, fertility percentage and T.K.W. Also there was not significant (P£0.05) for raceme length, raceme width and number of spiklet. Cultivars differences for yield and other indices were significant (P£0.01).Sowing dates 15 May and 22 July treatments was better than others for grain yield, fertility percentage and T.K.W. Sepideh variety was better than two other cultivars for grain yield and other indices. The highest grain yield (4.203 ton/ha) obtained from Sepideh cultivar and sowing date at 22 July. Consequently, it is recommended that Sepideh cultivar can be used as a best cultivar for cultivating during 7-16 July in Khouzestan province.
