Summary
This narrative review examines intercropping as a multifunctional cropping strategy, surveying published evidence on its capacity to improve growth and productivity through more efficient use of light, water, and nutrients. The paper highlights the importance of species selection and management in determining system outcomes, and discusses the role of legume inclusion in enhancing soil nitrogen availability. It positions intercropping as a broadly applicable sustainable intensification tool with particular relevance to smallholder and diversified farming contexts.
UK applicability
Although the paper is international in scope and likely draws heavily on research from South Asian and tropical contexts given the authors' institutional affiliations, the principles of intercropping — particularly cereal-legume combinations and resource use efficiency — are increasingly relevant to UK arable and mixed farming systems under agri-environment and sustainable farming incentive frameworks.
Key measures
Land equivalent ratio (LER); crop yield; soil fertility indicators; resource use efficiency; ground cover
Outcomes reported
The review reports on the agronomic benefits of intercropping, including resource use efficiency, soil fertility improvement, and yield gains from combining complementary crop species. It likely synthesises evidence on how crop selection, management practices, and climatic conditions influence intercropping system performance.
