Benefits of Plant Growth Promoting Rhizobacteria (PGPR) on Increasing Efficiency for Economic Crops

Abstract

Plant Growth Promoting Rhizobacteria (PGPR) or biofertilizer is used for promoting the plant growth. PGPR has several characteristics; namely to create the plant nutrients, adding certain plant foods, supporting plant hormones creation, and to create pest control substances. From above PGPR’s abilities,
there are recently number of studies, researches and development to apply on increasing efficiency for economic crops such as corn, rice, sugar cane and cassava. Most of the studies found that the use of PGPR on above mentioned 4 economic crops resulted in increasing productivity by 9.8-40% instead of reducing chemical fertilizers use by 25-50% referred to the suggestion of the Department of Agriculture. According to the study results, PGPR is useful technologies that can help farmers increase their productivity. However, it is necessary to continually study for the use of PGPR for different crops in different areas and
environments.
