Impact of Biological Fertilizers Based on Essential Bacterial Stimulants on Rice Growth and Production

Biological fertilizers are a group of living organisms whose activities can improve soil fertility, that contain microbes and useful for helping plant growth. The purpose this study was to analyze the growth production rice plants against application biological fertilizers. There 7 bacterial isolates used as biofertilizers, namely, Bacillus sp., two Pseudomonas sp. strains, Azospirillum Azotobacter strains. This an experimental design method through one-factor randomized block design. treatment in consisted no fertilization, compost, 100% NPK, enriched compost+50% 4 NPK. results showed compost with could increase nutrient content soil, thereby increasing plants. Treatment isolates+50% NPK gave highest yield, both use reduce dose inorganic fertilizer by up 50% cultivation.
