Other claims from this paper (9)
- Mechanism The authors attributed low millet yields mainly to acidification and organic matter loss.
- Intervention effect Ridging increased cowpea hay production 330% over four years versus bare plots.
- Mechanism The authors attributed the ridging benefit to lower penetration resistance and bulk density.
- Intervention effect Ridging reduced exchangeable acidity by 0.15 cmol(+)kg(-1).
- Observation Millet grain yield under banded surface mulch stayed near 526 +/- 9 kg ha(-1), except in the severe drought year.
- Observation Millet yield components compensated for each other depending on timing of abiotic stresses.
- Intervention effect Cowpea productivity was consistently higher with buried than surface banded mulch.
- Intervention effect Buried banded mulch failed to sustain millet yields.
- Mechanism The authors attributed millet yield decline under buried mulch to greater cowpea nutrient uptake and faster acidification.
