Other claims from this paper (10)
- Intervention effect Below-canopy PAR was significantly higher when maize followed cowpea by three weeks.
- Intervention effect Maize and cowpea LAI was significantly greater with same-day sowing.
- Intervention effect Maize yield declined with cowpea intercropping.
- Observation The maize yield reduction was greatest under simultaneous sowing.
- Observation The land-use benefit was not retained for maize equivalent yield.
- Observation Sole cowpea had the lowest maize equivalent yield of 6.03 ± 0.14 t ha−1.
- Observation Maize sown three weeks after cowpea gave the largest land equivalent ratio, 1.67 ± 0.05.
- Observation That intercropping treatment gave net income of USD 786.32 ± 25.08 ha−1.
- Recommendation The authors suggest three-week staggered maize–cowpea intercropping for sustainable land use.
- Observation The authors caution that the system may not give significantly greater maize equivalent yield or economic return.
