Does crop rotation yield more in China? A meta-analysis

Crop rotation has been widely used to mitigate weed, insect, and pathogen pressure, as well as to increase plant diversity. However, the magnitude of and variability in crop yield with rotation in China remain uncertain. We conducted a meta-analysis on 45 studies with 214 comparisons to examine the effects of crop rotation on yield and to explore the importance of environmental factors and field management in determining yield variability....
