Summary
This narrative review synthesises research on the wide and narrow row cropping (WNRC) system, an optimised planting arrangement that strategically alternates row spacings to improve canopy architecture and resource use. The authors assess evidence on how WNRC influences light interception, air circulation, nutrient competition, and weed management relative to conventional uniform row spacing. The review indicates that WNRC can enhance land use efficiency and crop productivity, though findings are likely drawn predominantly from Chinese cropping contexts.
UK applicability
The study appears to be based primarily on research conducted in China, where WNRC has been developed largely for maize, rice, and soybean systems. Principles relating to canopy light use and row spacing optimisation are broadly transferable to UK arable systems, though direct applicability would require validation under UK climate conditions, crop varieties, and farm-scale mechanisation constraints.
Key measures
Light interception; canopy microclimate; yield (t/ha); resource use efficiency; weed suppression; planting density
Outcomes reported
The review examines how wide and narrow row cropping (WNRC) configurations affect light interception, air circulation, resource use efficiency, weed suppression, and ultimately crop yield across multiple crop types.
