Other claims from this paper (9)
- Association Ash or lime improved yields where Ca saturation was below 0.62.
- Association Ash or lime decreased yields at higher Ca saturation levels.
- Association Varieties A-26 and VV yielded less than the local variety in several villages.
- Intervention effect K did not improve groundnut yields over the control.
- Intervention effect Tillage did not improve groundnut yields over the control.
- Association Liming and ash applications increased soil pH, exchangeable Ca and Mg.
- Association Liming and ash applications decreased exchangeable Al.
- Association P + K applications increased exchangeable K and extractable P.
- Observation Yield increases in local groundnut from liming or ash at low Ca saturation are relatively minor.
