Research was conducted in 2003 and 2004 to evaluate the effect of selected soil and foliar treatments on cotton. The research was conducted at 13 (2003) and 16 (2004) locations across the cotton belt. Treatments included; soil nitrogen (N) applied at recommended and 2/3 recommended rates were applied separately or in combination with a soil applied organic acid and/or CoRoN 10-0-10 0.5B as a foliar N and K treatment, for a total of eight treatments. The experimental design was a randomized complete block with treatments replicated four to six times. All recommended cotton production practices were utilized for production at the locations. For statistical analysis, yield means for each treatment was averaged across replications for each location and utilized as a replication in the final analyses. Foliar treatments were initiated at first bloom and followed with additional applications when petiole N and/or K concentrations were below the sufficiency range as determined by a Cardy meter. With the implementation of Nutrient Management Plans, cotton producers may have to reduce nutrient application rates at planting, particularly N, in order to minimize the environmental effects. These data suggest an alternative fertilization system for maintaining high cotton yields at reduced N rate.
