| Abstract | ||
| T his study examined the effects of biochar and nano-phosphorus (nano-P), applied individually and in combination, on biomass production, yield, nutrient uptake in common bean (Phaseolus vulgaris L.), and soil fertility over two growing seasons (2022–2023). A randomized complete block design with eight treatments was implemented: T1 (75% superphosphate), T2 (75% superphosphate + biochar), T3 (25% nano-superphosphate), T4 (25% nano-superphosphate + biochar), T5 (100% superphosphate), T6 (100% superphosphate + biochar), T7 (50% nano-superphosphate), and T8 (50% nano-superphosphate + biochar). Results showed that biochar addition significantly improved plant performance, increasing biomass, seed yield, and enhancing nutrient availability in the soil. 50% nano-superphosphate (T7) surpassed the full dose of conventional superphosphate (T5), indicating that partial replacement of mineral phosphorus with nano-P, especially when combined with biochar, can optimize productivity while reducing fertilizer use. All measured parameters, including fresh and dry weight, seed and straw yield, and nutrient uptake, significantly improved (p ≤ 0.01) with increasing treatment intensity from T1 to T8. Seed nitrogen uptake more than doubled from T1 to T8, and seed protein content rose from ~19.3% to ~24.5%. Phosphorus and potassium uptake also significantly increased. Soil analysis revealed notable increases in available N, P, and K under T8 compared to T1. These findings demonstrate the use of 50% nano-P combined with biochar is proposed as environmentally sustainable strategy to reduce phosphorus input. Also, even a 25% nano-P produced results comparable to a full dose of conventional superphosphate, underscoring the potential to lower fertilizer inputs while maintaining both yield and quality. | ||
