Other claims from this paper (15)
- Intervention effect Phosphorus and potassium fertilizer significantly enhanced chickpea nodulation.
- Intervention effect Phosphorus and potassium fertilizer significantly enhanced chickpea grain yield.
- Intervention effect Phosphorus and potassium fertilizer significantly enhanced nutrient uptake.
- Intervention effect Biochar at 95 tons ha−1 significantly increased chickpea nodule number to 122.
- Observation The 130 tons ha−1 biochar treatment produced a statistically similar nodule count to 95 tons ha−1.
- Observation Half and full mineral fertilizer treatments differed significantly in soil organic matter.
- Intervention effect Biochar at 130 tons ha−1 increased soil organic matter from 1.67% to 2.59%.
- Intervention effect Mineral fertilizer did not significantly enhance total soil nitrogen.
- Intervention effect Mineral fertilizer did not significantly enhance mineral soil nitrogen.
- Intervention effect Biochar increased total soil nitrogen versus control, peaking at 0.082% with 130 tons ha−1.
- Observation The biochar control had the lowest total soil N, 0.049%.
- Observation The biochar control had the lowest mineral soil N, 54 mg kg−1.
- Observation Biochar and mineral fertilizer interactions were generally nonsignificant for most soil and plant parameters.
- Recommendation Authors concluded that multi-year biochar at 95 tons ha−1 or more increased study parameters.
- Recommendation Authors concluded that lower mineral fertilizer doses further improved biochar performance.
