Timing and Rates for Nitrogen Foliar Fertilization of Cotton

Frank Smith, Norman Malm, and Carl Roberts


 
ABSTRACT

Foliar timing and rate experiments were conducted to evaluate the response of foliar applied nitrogen on lint yield and fiber quality of Acala cotton (Gossypium hirsutum). In the timing study, urea was foliar applied at 5 lbs N/A on July 15 and 30, and August 15 and 30. The highest yielding foliar combination was produced with the July 15 and August 15 spray dates. The three highest yielding foliar combinations all had an August 15 application date. Generally, the highest yields were associated with the early and mid-seasonal applications. In the rate study, urea and a commercial blend of 12-6-6 generally had a positive affect on yield. Uran caused foliage burn that reduced yields.
