Other claims from this paper (15)
- Intervention effect A biochar rate of 24 t/ha increased soil available N relative to no biochar.
- Intervention effect A biochar rate of 24 t/ha increased net photosynthetic rate of leaves and relative chlorophyll values (SPAD) relative to no biochar.
- Intervention effect B1 biochar increased total root length by 8.5∼29.9% relative to B0.
- Intervention effect B1 biochar increased root surface area by 13.5∼18.5% relative to B0.
- Intervention effect B1 biochar increased root volume by 0.8∼12.1% relative to B0.
- Intervention effect B1 biochar increased root bleeding sap (RBS) by 27.6–45.9% relative to B0.
- Association Grain yield was significantly correlated with SPAD and RBS under biochar treatment.
- Mechanism The authors attribute the biochar increase in grain yield to improved photosynthesis and root activity.
- Intervention effect MDI significantly increased peanut yield relative to drip irrigation (CK).
- Intervention effect MDI significantly increased net photosynthetic rate and RBS of peanut relative to drip irrigation (CK).
- Intervention effect MDI had no significant effect on soil available N relative to drip irrigation (CK).
- Intervention effect Moderate biochar under MDI (IMDIB1) gave the highest peanut yield over three years.
- Intervention effect Biochar at 24 t/ha combined with MDI achieved the highest soil available N, root development, and net photosynthetic rate.
- Intervention effect Biochar at 24 t/ha combined with MDI resulted in the highest grain yield.
- Recommendation The authors recommend the biochar and MDI combination as a management strategy to increase peanut yield.
