Other claims from this paper (18)
- Method / resource APSIM captured grain yield dynamics with IA 0.91.
- Method / resource APSIM captured total biomass with IA 0.90.
- Method / resource APSIM captured leaf area index with IA 0.77.
- Method / resource APSIM captured pearl millet height with IA 0.96.
- Method / resource APSIM captured cowpea height with IA 0.81.
- Method / resource APSIM captured soil water with IA 0.73.
- Method / resource Pearl millet yield RMSE was 469 kg/ha.
- Method / resource Cowpea yield RMSE was 322 kg/ha.
- Method / resource Relative model error was high in the low-yielding environment.
- Intervention effect Increasing water supply raised yield in sole and intercrop systems.
- Observation Sole cowpea performed relatively better under low water supply.
- Intervention effect High plant density lowered yield under low water supply.
- Intervention effect High density raised yields only when water supply was high.
- Observation The highest total intercrop yield at high density was 4,000 kg/ha.
- Observation The highest total intercrop yield at low density was 3,500 kg/ha.
- Recommendation The authors support low planting density under water scarcity.
- Observation Intercropping did not inherently increase yield or reduce drought risk.
- Recommendation Intercropping offers diversification through protein-rich cowpea.
