EFEK FITOHORMON PGPR TERHADAP PERTUMBUHAN TANAMAN JAGUNG (Zea mays)

Abstract

Plant Growth Promoting Rhizobacteria (PGPR) is hyper Rhizobakteri growing
plants, which are groups of beneficial bacteria that actively colonize rizosfir. Plant
growth hormones will meet their needs through the ability to get from rizosfir and filosfir
as a result of the activity of PGPR in synthesising fitohormon. In the rhizosphere zone,
the interaction of plants with PGPR has a very important role in maintaining soil
biological environment. One of the most common ways how PGPR increase nutrient
capture by plants that alter plant hormone levels. The purpose of this article shows the
effect of PGPR on plant growth fitohormon corn. Some of the genus Pseudomonas,
Azotobacter, Bacillus, and Seratia identified as PGPR fitohormon producer that can
improve plant growth and yield of maize.
