Other claims from this paper (15)
- Intervention effect Ploughing plus harrowing plus ridging gave the highest tomato mean fruit weight, 8.16 t/ha.
- Intervention effect Ploughing plus harrowing plus ridging gave the highest tomato plant height and tap root length.
- Observation Manual mounding gave tomato fruit yield of 7.05 t/ha.
- Observation Ploughing plus harrowing gave tomato fruit yield of 6.24 t/ha.
- Observation Ploughing gave tomato fruit yield of 5.81 t/ha.
- Observation Manual clearing gave the lowest tomato yield, 5.03 t/ha.
- Intervention effect Tillage treatments lowered soil bulk density relative to manual clearing.
- Intervention effect Tillage treatments raised tomato leaf N, P and K relative to manual clearing.
- Intervention effect Tillage treatments raised tomato leaf Ca and Mg relative to manual clearing.
- Mechanism The authors attributed improved nutrient availability and tomato yield under ridging to reduced soil bulk density.
- Intervention effect Manual mounding increased tomato fruit yield by 40% compared with manual clearing.
- Intervention effect Ploughing increased tomato fruit yield by 16% compared with manual clearing.
- Intervention effect Ploughing plus harrowing increased tomato fruit yield by 24% compared with manual clearing.
- Intervention effect Ploughing plus harrowing plus ridging increased tomato fruit yield by 62% compared with manual clearing.
- Recommendation The authors recommended ploughing plus harrowing plus ridging for commercial tomato production on humid tropical Alfisol.
