Interpretive Summary: While an adequate supply of all plant nutrients is essential for successful cotton production, management of N is especially important. Both pre-season and in-season monitoring of N is needed to maximize N efficiency. A shortage of adequate N during intense demand periods of peak bloom and first boll opening will reduce yields. An excess supply of N during early vegetative stages and in the late season cut-out will be detrimental to yield and quality.

Technical Abstract: An adequate supply of N is essential for successful cotton production. Sufficient N initially supports rapid development of leaves and roots. Later in the season, most of the N is found in the seeds. Understanding cotton development aids in efficient nutrient management.
