Other claims from this paper (12)
- Intervention effect Lime and phosphorus significantly improved maize stand count, root and stem weights, and yield.
- Intervention effect Lime and phosphorus significantly improved bean stand count, root and stem weights, and yield.
- Intervention effect Lime and phosphorus significantly improved Irish potato stand count, root and stem weights, and yield.
- Intervention effect Liming raised yield most at low phosphorus rates; its yield effect declined as phosphorus rose.
- Intervention effect Mucuna green manure reduced maize phosphorus requirement by 45 to 83%.
- Intervention effect Liming raised soil calcium, pH and effective cation exchange capacity.
- Association Maize yield correlated positively with pH, ECEC and exchangeable calcium.
- Association Bean yield correlated positively with pH, ECEC and exchangeable calcium.
- Association Maize yield related inversely to total acidity and aluminium saturation.
- Association Bean yield related inversely to total acidity and aluminium saturation.
- Observation Liming at 2 t ha^-1 was uneconomical at current lime and phosphorus fertilizer prices.
- Recommendation The authors recommend lower lime rates or Mucuna manure with less than 85 kg ha^-1 phosphorus fertilizer to sustain production.
