Cotton-Based Rotation, Intercropping, and Alternate Intercropping Increase Yields by Improving Root–Shoot Relations

Crop rotation and intercropping are important ways to increase agricultural resource utilization efficiency crop productivity. Alternate intercropping, or transposition is a new pattern in which two crops intercropped wide strip with planting positions switched annually on the same land. Transposition combines thus performs better than either practice alone. Compared traditional rotation, it can yield net return by 17–21% 10–23%, respectively, land equivalent ratio (LER) 20% 30%. In growth development, balanced root–shoot relation essential obtain satisfactory yields quality. Intercropping, combination alter original changing ecology physiology of both root shoot achieve rebalancing relation. The quality regulated interactions resulting rebalancing. review examines effects above- belowground relations under cotton-based particularly alternate practices combined. importance signaling regulating was also explored as possible focus future research rotation.
