- •
The effects of controlled release nitrogen fertilizer (CRNF) on cotton yield were investigated.
- •
CRNF increased yield, N uptake and N use efficiency of cotton compared with urea.
- •
N release rate under field condition could be predicted by laboratory method.
- •
Releases rate of N from CRNF corresponded well to the N requirements of cotton plants.
