Other claims from this paper (9)
- Observation Maize growth varied with fertilizer type and rate.
- Intervention effect Organic fertilizer at 5 t ha−1 gave maize growth comparable to inorganic fertilizer.
- Intervention effect Organic fertilizer at 2.5 t ha−1 did not give comparable maize growth.
- Intervention effect Fortified OBF above 2.4% N at 5.0 t ha−1 gave maize grain yields comparable to NPK fertilizer.
- Intervention effect Cowpea yields were significantly lower with 2.5 t ha−1 OBFs.
- Intervention effect IAR&T-OBF and DPW + NPK at 5.0 t ha−1 gave comparable seed yields exceeding OYO-OBF.
- Intervention effect NPK supported early-season maize cultivation.
- Intervention effect NPK was inadequate for the following cowpea.
- Recommendation The authors recommend OBF with up to 2.4% nitrogen applied at 5.0 t ha−1 for maize followed by cowpea.
