Evaluation of Foliar Fertilizers in Cotton for Plant Growth, Yield, and Fiber Quality

Cotton nutrient recommendations have remained stagnant despite increases in lint yield which might result in plant nutrient deficits. One method for replenishing nutrients is foliar fertilization which is becoming more and more popular with growers. The purpose of this project is to 1)  determine if foliar applications of macro- and micronutrients have the potential to increase yield and fiber components of cotton when used as supplements to soil applied nutrients at levels to reach 100% of soil test recommendations; and 2) determine if the soil test recommendations remain adequate for current varieties and there yield potential. Discussion of results will include cotton plant mapping, lint yield, and fiber quality.
