Nitrogen and Cover Crop Effects on Yield and Fiber Quality of Irrigated Cotton

Effects of nitrogen (N) application rate and cover crop on yield and fiber quality of irrigated cotton were tested in the Mississippi Delta for three years. The test was conducted in 12 plots in one acre each. N application rates of 75 and 125 lb/ac with and without tillage radish as cover crop were used as the treatments. Irrigation was scheduled based on soil water content measured using soil moisture sensors. Cotton was harvested using a cotton picker. Cotton samples were collected and the yield and fiber quality were determined.  Nitrogen application rate and the cover crop influence on the yield and fiber quality were analyzed. Detail methods used and results obtained in this study were presented.
