Other claims from this paper (10)
- Observation Yield parameters of maize increased in the order control < 120 kg N ha-1 applied once < 90+30 < 60+30+30.
- Intervention effect 60+30+30 increased maize yield by 15.3% compared with 90+30.
- Intervention effect 60+30+30 increased maize yield by 37.1% compared with 120 kg N ha-1 applied once.
- Intervention effect 60+30+30 increased maize yield by 138.2% compared with the control.
- Observation 60+30+30 gave a net return of ₦ 227,600.
- Observation 60+30+30 had a benefit cost ratio of 3.67:1.
- Observation 120 kg N ha-1 applied once gave a net return of ₦ 157,200.
- Observation 120 kg N ha-1 applied once gave a benefit ratio of 2.9.
- Recommendation Farmers would benefit by adopting split application of N fertilizer three times (60+30+30) for more profit.
- Recommendation N fertilizer application should be structured in accordance with this uptake pattern to avoid losses by leaching.
