Effect of Irrigation and Nitrogen Application on Cotton Yield and Quality

Effect of nitrogen (N) application rate on cotton yield and fiber quality in irrigated and rainfed cotton were studied in a humid climate for two seasons. Experiments were set up in two irrigation regimes, irrigated and rainfed. Within each irrigation regime a Randomized Complete Block (CRB) design was employed with five N treatments and three replications. Cotton yield and fiber quality data were collected. Relationship among N application rate, leaf N, yield, and fiber quality was statistically analyzed. Results will be reported in this paper.
