: ‭This study aimed to investigate the effect of manure on the growth , survival and germination properties of pinus brutia seedlings in Shoorab nursery. Factorial completely randomized experimental design was considered for this study and poultry manure at three levels of 0 , 75 and 150 g and sheep manure at three levels 0 ,125 and 250 g per pot with 4 replicate and 15 pots per each replicate was used.with the end of the germination on period calculated germination rate, mean germination time, germination power and germination speed. Based on results, 125 g sheep manure with 75 g poultry manure treatment shows the maximum amounts of germination rate, mean germination time, and germination power. After the end of growing season, qualitative and quantitative properties such as seedlings height, collar diameter, shoot/root ratio, shoot/root ratio biomass, total biomass, vitality and survival were measured. Results showed that there are significant differences in the main effects of poultry manure, sheep manure, and the interaction of these factors on seedlings height, collar diameter, and total biomass. The most values of seedlings height, collar diameter, and total biomass were seen in combination of 75 gr poultry manure, 125 gr sheep manure and nursery soil treatment. There are significant differences in the main effects of poultry manure, and sheep manure, on shoot/root ratio, shoot/root ratio biomass and survival, but the interaction of poultry manure, and sheep manure does not show significant differences on shoot/root ratio, shoot/root ratio biomass and survival. the most values of survival were seen in combination of 250 gr sheep manure and nursery soil treatment and the most values of shoot/root ratio and shoot/root ratio biomass were seen in 5,6,8 and 9 treatment. Also different treatments had asignificant effect on the vitality of seedling. The best condition for successful growth of Pinus brutia seedlings were seen at enough nutrient, low EC, and neutral pH soils.It is concluded that combination of 75 gr poultry manure, and 125 gr sheep manure is the best treatment for Pinus brutia seedlings production.‬
