Abstract: 

In order to study density of crucible and application of various levels of nitrogen on yield and yield components and some physiological characteristics of speed feed cultivar of forage sorghum, this research was done in the research farm of the Islamic Azad University of Arak, Iran in 2008. The experiment was conducted as a factorial design based on CRDB with four replications. Factors were selected as rates of nitrogen application in three levels (150, 250 and 350 kg/ha) and different planting densities (200, 300 and 400 thousands crucible/ha). Results showed that the effect of different nitrogen application levels on panicle height were significant (sig.%1). Also, interactions of traits on wet forage, number of tiller per pinnacle and dry to wet weight were significant. The highest yield of wet forage was 49.5 ton/ha in 400 thousands crucible/ha and 350 kg/ha nitrogen application when maximum level of factors were obtained.
