Varietal Differences in Cotton

   The seven color image above, shows a classified image of a small cotton field in North Alabama. The image shows seven relative differences of vegetation in the field. The field is irrigated with nitrogen water through a pivot irrigation system.
       The field was planted in three different cotton varieties. A classified image can be very beneficial in this situation. Instead of making a blanket application of a growth regulator or a defoliant over the different varieties the grower can use this image to apply the right amount to each of the different varieties.
       In addition, the grower will be able to adjust the rates for the weaker cotton outside the pivot. This cotton is basically dryland cotton and will not grow as tall and bushy compared to the cotton under the pivot.
