Abstract

Acacia (Acacia crassicarpa) is a type of plant that is very potential to be developed in industrial plantations because acacia is a fast growing plant species and does not require high growth requirements. To increase the growth of acacia seeds fertilization is needed. Fertilization with compound fertilizer can meet the nutrient needs of plants during the nursery because it has more than two types of nutrients. This study aims to evaluate the growth of acacia seedlings fertilized with various types of compound fertilizers. Allegedly the best growth of acacia seedlings in the treatment of NPK 6-23-10 g plant-1. The study was conducted in July to November 2019 at the PT Pusri Palembang Experimental Garden, Kalidoni, Palembang, South Sumatra. The study used a Randomized Block Design (RBD) with 5 treatments and 4 replications so that 20 experimental units were obtained with the treatment of P0 (Control), P1 5 g of NPK plants-1 (15-15-15), P2 5 g of plant-1 NPK (6 -23-10), P3 5 g of plant-1, NK (10-0-30), P4 5 g of plant-1 NP Humat (42-6-0). The variables observed in this study were the characteristics of some initial planting media characteristics, plant height (cm), plant diameter (mm), number of leaves (strands), total leaf area (cm2), leaf greening level, canopy wet biomass and roots (g ), canopy and root dry biomass (g), plant nutrient uptake after the study (mg plant-1) and soil nutrient content after the study. Data were analyzed statistically with the method of analysis of variance (ANOVA) to see the effect of fertilizer variation treatment followed by the Duncan Multiple Range Test (DMRT). The results of this study showed that the treatment of compound fertilizer significantly affected the number of leaves (strands), the level of greenness of the leaves, canopy wet biomass (g) and nutrient uptake of N (mg plant-1), but not significantly to plant height (cm), stem diameter (mm), leaf area (cm2), wet root biomass (g), canopy dry biomass (g), root dry biomass (g), nutrient uptake of P, K, & Mg (mg plant-1), total nutrient content of N (%), P (%), K (%) and C-organic (%). Provision of NPK 6:23:10 compound fertilizer as much as 5 g of plant-1 gives plant height, stem diameter, number of leaves, canopy dry biomass, root dry biomass, N, K and Mg uptake respectively 33.23 cm, 4.53 mm, 14.59 strands, 7.30 g, 2.22 g, 56.96 mg plant-1, 102.98 mg plant-1, 0.008 mg plant-1.
