Biofertilizer Formulation with Bioactivators Bacillus cereus on the Growth and Yeild of Upland Rice (Oryza sativa L.) in Peat Medium

This study aims to test the bio-fertilizer formulation with Bacillus cereus bioactivator and to obtain the best bio-fertilizer formulation for the growth and yield of upland rice (Oryza sativa L.) in peat medium. The research was conducted in the experimental garden and Soil Science Laboratory, Faculty of Agriculture, University of Riau from July to October 2018. The study was carried out experimentally using a completely randomized design (RAL) with the treatment tested was the formulation of Bacillus cereus (F): F0: 100 ml Bacillus cereus without formulation, F1: 100 ml Bacillus cereus inoculant+74% bagasse+13% dolomite+13% zeolite, F2: 100 ml Bacillus cereus inoculant+74% rice husk+13% zeolite+13% dolomite, F3: 100 ml inoculant Bacillus cereus+74% solid+13% dolomite+13% zeolite, F4: 100 ml Bacillus cereus inoculant+74% tkks+13% zeolite+13% dolomite. The data obtained were analyzed statistically using variance fingerprints. The average result of the analysis was continued with the BNJ test at the 5% level. The results showed that administration of Bacillus cereus without formulation and with the formulation of solid organic matter of rice husks, solids and oil palm empty bunches showed a good response to the amount of chlorophyll and yield of upland rice plants.
