In onder to study the effect of sowing date on yield and yield components of pop corn varieties an experiment was conducted for two years(2001-2003 farming seasons)at Behbahan Agricultural Research Station. A split plots experiment in randomized complete blocks design was used with four replications. Three sowing dates were considered as main plots(Aug.5,Aug.15,Aug.25). Sub plots were including of three varieties: ZK1533, ZK4722AA(KSC600), ZK1533/2, ZK4722AA,ZK298, ZK4722. Yield variance analysis results showed effects of sowing date and variety were significant at 1% level and interaction effect of sowing date and variety was not significant. Aug.5 was the suitablest of sowing date with yield of 8.512 t/ha. The best variety was ZK1533,ZK4722AA(KSC600) and produced the heightest yield(8.108 t/ha). In interaction effect of sowing date and variety KSC600 variety at Aug.5 had the heightest yield(9.375 t/ha). KSC600 variety at Aug.5 was the superior treatment for yield components(172.5 g thousand kernel weight, 16.75 kernel row,40.38 kernel per row).
