Nitrogen application effect on leaf photosynthesis, nonstructural carbohydrate concentrations and yield of field-grown cotton.

Zhao DuLi, Derrick M. Oosterhuis

Abstract

The indeterminate growth habit of cotton (Gossypium hirsutum L.) plants makes them very responsive to changes in the environment and management. Both extra nitrogen (N) application and N deficiency affect the growth and yield. Leaf photosynthesis and plant carbon metabolism are the bases of crop growth and yield development. Therefore, investigating the effect of N deficit on carbohydrate content of plant tissues can help us to understand the physiological mechanism of low N influencing cotton yield.
