Abstract: 

The study aimed to improve the yield of biogas production during the anaerobic fermentation process of raw poultry droppings (PD) during the year (2018) from the layers farm (Al-jremkia) site which is affiliated to Agriculture Directorate in Lattakia. Then PD was mixed with starter (S) then it was mixed with both starter and tree leaves (TL). Three treatments from poultry droppings were prepared and each one was repeated (9) times. The first treatment was raw poultry droppings (T1), the second treatment was poultry droppings with starter, and the third was poultry droppings with both starter and tree leaves. The results showed that treatment (T3) was significantly superior to both treatments (T2, T1) in the amount of biogas produced at a significant level of (5) %, as the amount of biogas produced for each of them reached (3751.67, 608.67, 167.85) ml, respectively during (23) days.

Keywords: poultry droppings, anaerobic fermentation, starter, tree leaves, biogas.
