Abstract :

This experiment was conducted to evaluate the effects of sowing date on yield and its components of 8 sweet corn hybrids in Jiroft area in 2007 at Agricultural Research Center of Jiroft and Kahnouj, Iran. The design was laid out as a split plot design based on RCBD with three Replications. The main factor had two levels of sowing date (August 22ed, September 6th) and subplots were 8 hybrids (EXO8716636, Obsession, Harvest Gold, Chase, Temptation, Challenger, Basin and Power House). The result showed that highest economical yield (ear fresh weight at economical harvest) were obtained in August 22ed with 27.54 ton/ha and ear fresh yield was 24.05 ton/ha in September 6. The highest and lowest ear fresh yield were obtained about from cultivar Basin 30.73 ton/ha hybrid temptation 20.42 ton/ha respectively. Maximum ear fresh yield with 32.42 ton/ha and  31.87 ton/ha were obtained from hybrid Basin and Power house in planting date August 22. Finally, sweet corn cultivars, Harvest Gold, Power House and Basin with August 22ed are recommended for the Jiroft region.
