Abstract: 

To evaluate forage yield and quality of sweet corn as affected by plant density and sowing date, a field experiment was conducted at Tarbiat Modarres University in 2004. Experiment was carried out in a split plot design based on RCBD with four replications. In this research four levels of sowing date (May 22th June 10th, July 1st and July 21th) and four plant densities (45, 55, 65 and 75000 plants/ha) were arranged in main and sub-plots, respectively. The results in the first sampling (%50 silking) showed that plant density and sowing date have significant effects on some traits such as leaf and stem weigh (fresh and dry), LAI and leaf/stem ratio. In the second sampling (after ear harvest in soft dough stage) total forage yield, crude protein and mineral nutrients (P, Ca, Na, K, and Mg) were determined. and most of them were affected by plant density and sowing date. Sweet corn which was sown on 10th, June produced the highest forage yield (50ton/ha).
