Farmers in the upland can raise their harvest through bacteria that Philippine Rice Research Institute found to increase plant growth rate and yield. Researchers, led by scientist Jayvee A. Cruz of PhilRice, discovered that actinomycete (Streptomyces mutabilis), a plant growth-promoting bacteria (PGPB), showed promising results. Based on Mr. Cruz’s study, actinomycete, an aerobic bacterium suitable under upland conditions, can increase root dry weight, number of tillers, and root depth of upland rice. It can also promote growth even under moisture stress. “The country’s production of upland rice remains low, at approximately 2 t/ha only. By applying half fertilizer treatment combined with PGPB treatment, farmers can get additional yield of 0.5 t/ha,” Mr. Cruz said. Mr. Cruz also said that it needs a lesser amount of chemical fertilizer for soil treatment, which can address environmental concerns and rising cost of fertilizers. The 32-year-old scientist, however
