Sugarcane yield response to legume intercropped: data from experimental network and review

Intercropping with legumes has attracted much attention worldwide, regarded as a sustainable alternative to chemical N-fertilizer. Many studies have investigated the effects of introducing legumes into sugarcane systems. However, how agro-environmental conditions influence the effect of legumes on sugarcane yield is still unclear. These data were compiled to performed a meta-analysis which i) quantify the effect of legume intercropping on sugarcane yield, ii) assess how agro-environmental and management conditions influence the response of sugarcane yield to intercropping, and iii) assess the influence of legumes in interaction with weeds on sugarcane yield. We combined data from a systematic literature review and experimental data from a network of trials conducted in the tropical island of La Reunion.
