Abstract

This research was conducted in the experimental field of Andalas University Campus Dharmasraya, from January to August 2018. The purpose of this study was to obtain the best dose of rice husk biochar for the growth of oil palm seedlings in main nursery. This study was compiled based on Completely Randomized Design (CRD) with 5 treatments and 5 replications and in each plot there were 2 plants. The results of the observations were analyzed of variance and if significantly different then continued with Duncan's New Multiple Range Test (DNMRT) at the level of 5%. The treatment dose is P0 = 0 g of rice husk / polybag biochar, P1 = 150 g of rice husk biochar / polybag, P2 = 200 g of rice husk biochar / polybag, P3 = 250 g of rice husk biochar / polybag and P4 = 300 g of rice husk biochar / polybag. The parameters of observation were plant height, hump circumference, number of leaves, leaf length, root length, and biomass. The results showed that the application of rice husk biochar had a significant influence on plant height with the best dose of 250 g of rice husk biochar / polybag.
