Abstract:

In order to find the most suitable planting date for more producing silage corn hybrids, the field experiments were conducted for two years at agricultural research station Iranshahr in 2004-2005. The cultivars were sown at three planting dates from 16 July with 15 days interval. The experimental was laid out in a split plot randomized complete block design arranged with four replications. The main plots were planting date and the sub-plot consisted of varieties. The harvesting areas for early matured, mid matured and later matured varieties were 10.08, 9.27 and 8.48, respectively. The usual agricultural planting were done. During the growth the usual notes were taken. The analysis revealed that late variety single cross 711 with 42.75 Ton ha-1 had the highest yield on August 1 planting date and single cross 301 on July 16 planting date produced the lowest yield (26.81 Ton ha-1).
