The management of nitrogen (N) in the production of cotton (Gossypium hirsutum L.) is one of the most important decisions producers make during the growing season.  .  The under-application of N can result in stunted plants, lower boll production and reduced yield.  Over application can cause excessive vegetative growth, restrict boll production, and the loss of unused N into the environment.  The use of optical crop sensors and normalized difference vegetation index (NDVI) to determine plant health and growth gives producers options to consider along with environmental conditions and yield potential.  Making an on-the-go application of N at early bloom gives producers flexibility and better utilization in managing their N needs.
