Abstract


Rice (Oryza sativa L.) productivity is closely associated with soil quality. Biochar and raw cattle manure are potential soil amendments that improve soil properties and support plant growth. This study evaluated the effects of their combined application on rice vegetative growth, total soil fungal population, and their relationships. A greenhouse experiment was conducted from December 2025 to June 2026 using a Randomized Block Design with five treatments and four replications. Observed variables included total soil fungal population, plant height, number of leaves, leaf area, number of tillers, shoot fresh weight, shoot dry weight, root fresh weight, and root dry weight. Data were analyzed using analysis of variance (ANOVA), the Least Significant Difference (LSD) test at the 5% level, and Pearson correlation analysis. The combined application of biochar and raw cattle manure significantly affected total soil fungal population and all vegetative growth parameters. Raw cattle manure produced the highest soil fungal population, whereas biochar (15 t ha⁻¹) combined with raw cattle manure (40 t ha⁻¹) resulted in the best vegetative growth. Correlation analysis showed weak to moderate relationships between soil fungal population and vegetative growth, indicating that plant performance was influenced more by improved nutrient availability than by fungal population alone. These findings demonstrate the potential of combining biochar and raw cattle manure to support sustainable rice cultivation.
