Advantages of Amending Chemical Fertilizer with Plant-Growth-Promoting Rhizobacteria under Alternate Wetting Drying Rice Cultivation

Chemical fertilizer (CF) is necessary for optimal growth and grain production in rice farming. However, the continuous application of synthetic substances has adverse effects on natural environment. Amending with plant-growth-promoting rhizobacteria (PGPR) an alternate option to reduce CF usage. In this study, a field trial was undertaken southern Taiwan. We aimed investigate reducing CF, either partially or completely, PGPR vegetative growth, biomass production, yield plants cultivated under wetting drying (AWD) cultivation. addition, we determine reduction dose when incorporated cultivation AWD. The consisted four treatments, namely, 0% + 100% (FP1), 25% 75% (FP2) 50% (FP3), (CONT). A randomized complete blocked design (RCBD) three replicates used. by 25–50% difference compensated significantly (p ? 0.05) influenced crops production. This improved percentage filled grains (PFG), thousand-grain weight (1000-GW) treated 4–5%. These improvements components eventually increased 14%. It concluded that partial replacement could be viable approach use existing systems. Furthermore, potential as sustainable technique
