Summary
This field study examines how rotating the spatial arrangement of maize and peanut strips in an intercropping system, combined with reduced nitrogen fertiliser input, can minimise nitrogen loss and maintain nitrogen cycling efficiency. The research suggests that strip rotation—an agronomic management practice—provides a mechanism to optimise nitrogen balance without proportional reductions in yield, thereby lowering external nitrogen input while preserving productivity. The findings contribute to evidence for intercropping design as a tool for enhanced nutrient stewardship in cereal–legume systems.
UK applicability
The applicability to UK conditions is limited, as maize–peanut intercropping is not a conventional UK farming system and climate–phenology constraints differ markedly. However, the underlying principles of strip rotation and legume–cereal nitrogen cycling may inform research into temperate intercropping systems (e.g. with field beans or clover) and integrated nitrogen management strategies in mixed farming.
Key measures
Nitrogen loss (likely via leaching and/or volatilisation), nitrogen use efficiency, nitrogen balance, grain yield, aboveground biomass, nitrogen uptake by maize and peanut
Outcomes reported
The study measured nitrogen loss pathways, nitrogen use efficiency, and nitrogen balance in maize–peanut intercropping systems under different strip rotation arrangements and nitrogen fertiliser application rates. Agronomic outcomes included grain yield, biomass accumulation, and nutrient uptake by both crops.
