Identifikasi dan uji efektivitas rizobakteri dalam meningkatkan hasil tanaman kacang tanah

In order to increase groundnut productivity, it is necessary to find agents that can improve the growth and yield of it. This study was done to determine the potential use of rhizobacteria to promote the growth and increase the yield of groundnut under green house experiment. The research was conducted in the plant disease laboratory, Faculty of Agriculture, Udayana University, in June 2022-January 2023. Five isolates of rhizobacteria namely FN1, FN2, FL3, FL4, and FL5 were tested for their effectiveness in promoting the growth, increase the yield, and protein content of groundnut. Molecular identification based on 16S rRNA gene sequence showed that FN1 and FL5 were similar to Klebsiella pneumonia with the similarity level at 98%. FN2 was similar to Klebsiella variicola with 99% similarity, FL3 was similar to Proteus mirabilis with 100% similarity, and FL4 wassimilar to Providencia rettgeri with 99% similarity. Rhizobacteria treatments significantly improved the groundnut growth, in which plant height, dry weight of shoot, dry weight of root, chlorophyll content, and the number of nodule significantly (p
