Other claims from this paper (13)
- Intervention effect Chicken manure produced higher plant height, stem diameter, leaves per plant than cattle manure in both soils.
- Intervention effect Chicken manure produced higher dry matter yield than cattle manure in both soils.
- Intervention effect Chicken manure produced higher tissue concentration of protein, nitrogen (N), and phosphorus (P) than cattle manure in both soils.
- Intervention effect Maize responded more to manure in loam than clay soil.
- Intervention effect Cattle manure produced maize responses below control in many cases.
- Intervention effect Wood ash generally improved maize responses in loam.
- Intervention effect Adding wood ash to manure in clay soil reduced maize plant height versus control.
- Intervention effect Adding wood ash to manure in clay soil reduced maize dry matter yield versus control.
- Intervention effect Adding wood ash to manure in clay soil reduced maize plant tissue protein and phosphorus versus control.
- Intervention effect Wood ash improved maize responses with cattle manure in both soils.
- Intervention effect Increasing chicken manure rate produced greater maize responses without ash than with ash.
- Intervention effect With cattle manure, wood ash produced better maize responses at 5 than 15 t ha−1.
- Recommendation The authors suggest that higher wood ash rates may have been needed.
