Abstract
Abstract: This study aimed to (1) determine the effect of each organic fertilizer dosage (a) the growth variables of Trembesi seedlin gs and (b) the quality of planting media after 120 days planted Trembesi Seedlings. This study also aimed to (2) obtain t he optimum dose of organic fertilizer to be applied to the implementation of post mining land reclamation and revegetation within the Forest Cultivation Zone. This research used various manure: Control without fertilizer; NPK synthetic fertilizer control; chicken manure, cow manure, and organic litter compost. Each of the organic fertilizer was given at doses of 125, 250, and 375 g/polybag. The test plants used were Trembesi seedlings (Samanea saman) at 4 months of ag e.The experimental design was prepared using Randomized Block Design (RAK) with 5 replications in each test plant group. Data analysis was completed with Fisher LSD Test and Duncan Multiple Range Test (DMRT) as well as regression analysis.The treatment of organic fertilizer dosage showed s ignif icant in all variables of growth of trembesi seedlings, except on average of Trembesi seedlings height at 90 days after planting (DAP) and on averag e stem diameter of Trembesi seed of 30, 60, 90, 120 DAP. Effect of organic fertilizer dosage to planting me dium after 120 days planted Trembesi seedling. All variations of fertilization dose increase the pH value, organic C, N total, C/N ratio, available P, available K, Ca++, Mg++, Na+, K and cation exchange rate (CEC). Treatment dose of 375g/polybag of chicke n manure was the best treatment dose with the highest number of twigs on Trembesi seedlings at the age of 30 DAP (21.00 twigs), 60 DAP (36.40 twigs), 90 DAP (63.60 twigs), 120 DAP (106.60 twigs), The Longest length of twig was foun d on Trembesi seedlings w ith age of 30 DAP (17.95 cm), 60 DAP(21.61 cm), 90 DAP (28.49 cm), 120 DAP (32.11 cm), longest root length and heaviest bioma ss weight of Trembesi seedling wasfor the age of 120 DAP, which were 58.80 cm and 487.22 g, respectively.
