Abstract

The beneficial soil microbes influence plant growth and soil quality. The soil microbes include phosphate solubilizing microbes and nitrogen-fixing bacteria. The experiments had been conducted to investigate the application of phosphate-solubilizing mircrobes and nitrogen-fixing bacteria and anorganic fertilizers on growth of upland rice on Andisols. This experiment used a Randomized Block Design (RBD) in factorial pattern, consisting of two factors with three replications. The first factor consisted of beneficial soil microbes, which were ; without soil microbes, consortia soil microbes A (Pseudomonas mallei, P. cepaceae, Aspergillus niger and Penicillium sp., Azotobacter chroococum, Azospirillum sp.) consortia B (Azotobacter choroococum, A. viilandii, Azospirillum, Pseudomonas cepaceae, Penicillium and Acitenobacter) and consortia A+B. The second factor were NPK fertilizers with four levels ( 100%, 75%, 50% and 25% dosage of recomendation). The results showed that the application of the beneficial soil microbes increased growth of upland rice and fertilizer efficiency.
