Abstract
En 中文
• Meta-analysis on the grain yield of arable intercrops in temperate alley-cropping. • 30 % average yield reduction in alley-cropping compared to full sun from 18 trials. • The negative effect of trees on yield increases with tree vicinity and tree aging. • Trees have lower detrimental impact on winter, especially barley, vs. summer crops. • Less detrimental or positive impact under low rainfall and high evapotranspiration.
