Crop row spacing in intercropping systems affects interactions of crop species and subsequent crop yields. In a field experiment, the response of crop yield to different maize row spacing (0-80 cm) in pea/maize intercropping system was investigated. The results showed that land equivalent ratio (LER) of each treatment exceeded 1,...
