Abstract

The objective of this study was to know the effect of plant growth promoting rhizobacteria on organic matter different dosages. This study was conducted in Educational and Research Garden of Instiper at Kalikuning Village, Depok Residence, Sleman, Yogyakarta Province, Indonesia. This study was started at June 18th 2020 until January 2nd 2021. Completely Randomized Design (CRD) was used in this two factorials experiment. The first factor was Plant Growth Promoting Rhizobacteria (PGPR) on 4 levels, those were 0 (control), 5 , 10 and 15 ml/l. The second factor was regusol and organic matter composition. Those were regusol and organic matter composition (1:0), (1:1), and (1:2). Anova was used to analyze if there were any significantly different and then to be continued with Duncan Multiple Range Test at 5 % level. The results of this study showed there were interaction significantly between PGPR consentration with organic matter composition on crown wet weight and crown dry weight. The most efficient was found on 9 ml/l PGPR and 1:1 composition of regusol and organic matter. Key words : pgpr, organic matter, oil palm seedling

本研究的目的是了解不同剂量促进植物生长的根杆菌对有机质的影响。本研究在印度尼西亚日惹省Sleman Depok Residence Kalikuning村的instper教育与研究园进行。本研究于2020年6月18日开始，2021年1月2日结束。本双因子试验采用完全随机设计(CRD)。第一个因子是植物生长促进根瘤菌(Plant Growth Promoting Rhizobacteria, PGPR)，在0(对照)、5、10和15 ml/l 4个水平。第二个因素是土壤酚和有机质组成。分别为有机质组成(1:0)、(1:1)和(1:2)。方差分析用于分析是否有显著差异，然后在5%的水平上继续进行邓肯多元范围检验。结果表明，PGPR浓度与树冠干重和树冠湿重的有机质组成之间存在显著的交互作用。以9 ml/l的PGPR和1:1的reusol与有机物组成为最有效。关键词:pgpr，有机质，油棕幼苗
