Abstract
Sustainable rice cultivation requires effective nutrient management strategies to reduce chemical fertilizer dependency. Biofertilizers enriched with humic acid and microbial consortia offer an eco-friendly alternative to enhance soil fertility and plant productivity. This study evaluated the effects of biofertilizer combined with humic acid and a microbial consortium on vegetative growth, chlorophyll content, and macronutrient availability in Inpari 32 rice. The experiment was conducted in a greenhouse at Banyuwangi State Polytechnic using a completely randomized factorial design with two biofertilizer types: biofertilizer + humic acid (B1) and biofertilizer + microbial consortium (Bacillus, Trichoderma, Saccharomyces) (B2), and three application doses: 300 g, 400 g, and 500 g per pot. Although ANOVA results indicated no statistically significant differences among treatments, a consistent positive trend was observed in plant height, tiller number, and chlorophyll content at the 400 g dose. Soil N, P, and K levels tended to decrease, possibly due to enhanced nutrient uptake by plants, suggesting an improved nutrient use efficiency. Overall, the combination of biofertilizer and humic acid at the 400 g dose tended to show higher values compared to other treatments, although these differences were not statistically significant. These findings support the use of multi-species microbial biofertilizers and IoT-based precision fertilization systems to promote sustainable rice production in Indonesia.
