The study was conducted at the Central Luzon, Barangay Buensuceso, Municipality of Arayat, Pampanga from May 2021 to July 2021 to find out the effects of different fermented legume leaves on the growth potential of Palawan Cherry Blossom (Cassia nodosa Buch.-Ham. ex Roxb.)seedlings. The experimental design was Randomized Complete Block Design (RCBD) with three replications of 20 seedlings for each treatment. There were four treatments used, namely: T1control (Untreated), T2fermented rain tree (Samanea saman) leaves, T3-fermented IpilIpil (Leucaena leucocephala) leaves, T4fermented Kakawate (Gliricidiasepium) leaves. Data were subjected to analysis of variance, LSD and means. No significant difference among treatments were observed for plant height, stem diameter, number of leaves, root-shoot ratio, and percent survival at day 60 after application of different fermented legume leaves. Highest plant height at day 60 was observed in T3 (26.92). Highest stem diameter at day 60 was observed in T1 (2.83). Highest number of leaves at day 60 was observed in T1 (10.83). Highest root-shoot ratio at day 60 was observed in T2 (4.51) and highest percent survival at day 60 was observed in T1, T2 and T4 with the same mean of (91.67%).
