- •
The type of cropping system significantly affected the N accumulation and partition in cotton.
- •
The cotton in wheat–cotton rotations showed a lower NHI and N use efficiency than in monoculture.
- •
The early maturity cultivar had higher N use efficiency in wheat–cotton rotations.
- •
The high N excess in the preceding wheat in wheat–cotton rotations led to significantly higher N surpluses.
