The control of cotton growth and boll production physiology is achieved by manipulating nitrogen and water, often in a negative manner. This research program was initiated to determine if substantial foliar applications of a high analysis foliar nutrient, Balance 1-18-18, could provide a positive management tool for these factors. Ten to twenty per cent of the P and K used by the cotton crop can be foliar applied safely and effectively to the cotton. Foliar applied Balance remains in solution on the leaf several hours after application and re-wets each evening even without dew. Square and boll counts increased on treated fields. Treated fields in Arizona matured about one month earlier than non treated. Treated fields in California produced about 200 lbs./ac. more lint. The entire program was effective in crop management and it was cost effective.
