The Effect of Plant Growth Promotion Rhizobacteria Inoculation To Agronomic Traits of Aromatic Rice (Oryza sativa CV. Inpago Unsoed 1)

The aim of this research was to study the effect of Plant Growth Promotion Rhizobacteria to improve agronomic traits of rice plant. The research was held in Agronomy and Horticulture Laboratory from September 2017 until March 2018. The research was arranged with randomized block design with three replications the treatment consisted of 9 isolates of PGPR and control. The observed variables including plant height, leaf area, number of tillers, leaf greenness, root dry weight, plant dry weight, total roots length, number of productive tillers, panicle length, number of grains per panicle, weight of 1000 seeds and grain yield. The result showed that inoculation of PGPR gave the effect on number tillers, plant height, but did not gave the effect on rice yield. Isolate R11 was the the best isolates that gave the effect on rice plant growth.
