The increasing demand of poultry meat in Pakistan has prompted more poultry forming with consequent effect on increase utilization of organic wastes (poultry manure) as fertilizers. In organic manures have considerable amount of organic matter, water content and mineral nutrients. A field experiment was conducted in research area of College of Agriculture, University of Sargodha, Sargodha, Punjab, Pakistan, to investigate the effect of poultry manure on the growth and yield of forage sorghum. For this purpose, four treatments (0 t/ha, 1t/ha, 2.5 t/ha and 4 t/ha) with three replications were used in Randomized Complete Block Design (RCBD). Plant height (cm), number of leaves per plant, stem diameter (cm2), fresh weight of forage (t/ha), dry weight of forage (t/ha), nitrogen% in plants, phosphorous% in plants and potassium % in plant were measured. The results showed that there were significant differences among treatments in most parameters during the growing period for growth characteristics under study. Maximum plant height (130 cm), number of leaves per plant (11), stem diameter (49 cm), fresh weight of forage (20 t/ha), dry weight of forage (5.5 t/ha), nitrogen % in plant (2.25%), phosphorous% in plants (18%), and potassium % in plant (17%) were examined where we applied 4 t/ha poultry manure. We concluded from this experiment that application of poultry manure at the rate of 4 t/ha improve the growth and yield of forage sorghum (Sorghum bicolor L.).
