Population Of Bacteria In Soil Dystrudepts Under Oil Palm In The Application Of Organic Mulch And Earthworm

Research on the effect of organic mulch and earthworms under oil palm plantation total population bacteria is still scarce. The study aims to analyze organich mulch, earthworm desity, interaction between density bacteria. research was carried out in May – August 2019. This a 3 x 4 factorial experiment which placed according Split Plot Design with basic design Randomized Block Design, each treatment repeated times. Organic as main plot are type, namely: M1 (M. bracteata), M2 (oil empty fruit brunches/ OPEFB) M3 midrib). subplots consists levels, C0 (0 worms/m2), C1 (35 C2 (50 worms/m2) C3 (65 worms/m2). data were analyzed using analysis variance. If significantly different, tested by Duncan’s at 5% significance level. results showed that midrib can increase fungi compared M. bracteata OPFEB. 50 65 worms/m2 bacterial other densities. combination
