Abstract

Biopriming is an innovative technique to enhance seed germination and health by promoting beneficial microbial colonization. This study evaluates the effects of biopriming using a consortium of beneficial microbes containing Bacillus subtilis, Bacillus pumilus, Bacillus cereus, Pseudomonas sp., and Rhizobium sp. on germination performance and microbial dynamics in oil palm (Elaeis guineensis) seeds. A randomized complete block design with a factorial approach was applied, involving three soaking treatments (NB formula, Effervescent formula and water as a control) and three seed varieties (Nirmala, Lestari, Sejahtera). The results indicate that biopriming significantly increased the abundance of nitrogen-fixing and phosphate-solubilizing bacteria before and after germination, positively impacting seed germination rates. Nirmala and Lestari varieties exhibited significant improvements in germination, whereas Sejahtera showed no substantial difference..This study confirms that microbial biopriming holds great potential for large-scale oil palm seed production, supporting sustainable agricultural practices. Further research is required to optimize microbial formulations and assess the long-term effects on plant productivity.
