Abstract

Twenty Iranian and introduction maize hybrids in five different maturity groups were studied in Zarghan, Shiraz for two cropping seasons (2007-2008). Three planting dates (27 May, 5 June, 15 June) and twenty maize hybrids were in split plot arrangements using randomized complete block design with three replications.. The planting dates were assigned to main plots and hybrids were randomized in sub-plots. Results indicated that late maturing hybrids will reach to proper harvestable moisture about early Oct., 18-22 Oct. and early-mid Nov. from 26 May, 5 June and 15 June sowing dates, respectively. In delayed planting, late maturing hybrids are to be replaced by medium and medium- early maturing hybrids to be harvestable in proper time with reasonable GRAIN YIELD. While late commercial hybrid, KSC 704 in 5 June sowing date ripe in early Oct. with GRAIN YIELD of 8667 kg.ha-1, medium hybrid KSC 400, 10-15 days earlier with GRAIN YIELD of 8809 kg.ha-1. This differences in maturity increased with further delay in planting as for 15 June to 15-20 days with GRAIN YIELD of 9341 kg.ha-1 without significan difference with KSC 704 with 11670 kg.ha-1 of GRAIN YIELD. There was significant difference between KSC 704 and KSC 400 for desirable grain quality as well as the time interval for land preparation for next crop.
