Abstract:

Square, bloom, and boll production of cotton increased as nitrogen fertilization was increased from 35 to 105 lb per acre. More boll weevils, Anthonomus grandis Boheman, were attracted to the more heavily fertilized cotton, and greater numbers of squares and bolls were damaged by weevils. However, the percentage of damaged fruits did not vary significantly. Consequently, both yield and weevil damage increased as nitrogen fertilization was increased.
