Nitrogen management plays a key role in cotton production. It is the nutrient required in greatest quantity by the crop and it is the nutrient most often deficient.

The wild ancestors of cotton are found in the arid regions of the world.

The aim of the project is twofold: to draw up a nitrogen budget for cotton under various conditions that are known to affect the crop's response to nitrogen; and to continue to develop the SJRATAC fruit model, in
