Effect of nitrogen application level on cotton fibre quality

摘要

The nitrogen(N)requirements of cotton are well understood and have been extensively studied since 1887,with practical guides,decision support systems,models and recent reviews providing information on the importance of providing cotton crops with a sufficient supply of nutrients and improving nitrogen use efficiency.Given that the financial return to the grower depends on both the cotton quantity and quality and the growing importance of the latter,this review focusses specifically on information and knowledge about the effect of nitrogen application level on fibre quality.
