Applying subsidized organic fertilizer made from bat guano can improve rice growth and production. In an experiment with different fertilizer treatments, adding organic fertilizer along with inorganic fertilizer increased plant biomass and grain yield. The treatment with a 5:5:5 ratio of organic fertilizer and inorganic fertilizer showed the best results, increasing straw percentage by 7.23% and total grain yield by 2.83%. This suggests that using organic fertilizer can enhance rice production, especially when combined with traditional fertilizers.
