Current Status and Prospect of Halotolerant Biofilm PGPR (Plant Growth Promoting Rhizobacteria) as Bioagent to Increase Crops Growth on Saline Soils

Abstract

Intensive crops farrmings Indonesia is higly depend on inorganic fertilizers and other agrochemical product that contribute to acceleration of land and environment degradation. Effort to alleviate the problems can be done by adopting the agro ecological agriculture approach that relies on environmentally friendly biofertilzers. This article is aimed to inventarize, review the current status and to promote the prospect of biofilm biofertilizer (BB) for improving the soil health and increasing the productivity of crops under salin Ecosystem. The research method was done by tracking, collecting and analyzing the secondary data from international journal and other reputable references. The reviewed results revealed that BB was introduced in and now is gaining more attention internationally. The beneficial microbes of BB are belong to group of bacteria, actinomycetes and fungi. The application of BB has shown the prospective in increasing the fertilizers efficiency and crops productivity on different agricultural soils. The growth of the crops were increased by root length by 57% and significant increases in dry biomass in roots, shoots, and spike by 92.3%, 40.7%, and 69.2 %. This study concludes that BB is highly prospective as a new era of biofertilizers for increasing the crops growth under saline soils.
