In order to investigate effects of Amount of phosphorus fertilizer and plant density on yield and yield components of sweet Sorghum, an experiment has been executed in the sugarcane research center and lateral industries. The experiment is done in the Split plot way and the complete random blocks format with three replications. In this experiment, phosphorus fertilizer is considered in three levels (60, 90,120 kg in a hectare). Also, plant density is considered in three levels (80000, 100000,120000 plants in a hectare) as a secondary factor. The results show that increasing amount of phosphor to 120 kg in a hectare causes meaningful changes in operation, biological yield and number of seeds in bunches. Also rising plant density to 120,000 plants in a hectare changes seed operation, number of seeds in bunches, weight of 1000 seeds, biological yield and harvest index dramatically. So, maximum and minimum seed yield are 2200 and 2100 kg in a hectare from 120 and 60 kg treatment in phosphor hectare, respectively. Moreover, maximum seed yield which is about 2300 kg in a hectare has been obtained from density of 120000 plants in a hectare. Also, minimum seed yield which is 2000 kg in a hectare has been gotten from density of 80000 plants. Generally, obtained results from investigation of mutual effects of phosphor average and plant density on seed yield shows that most amounts belong to 120 kg phosphorous treatment hybrid and density of 120000 plants in a hectare
