Testing to increase enhanced efficiency and nitrogen uptake by testing various rates and placement (band vs. broadcast) of nitrogen fertilizers.

Optimize nitrogen fertilization in dryland cotton by testing various blends of controlled-release fertilizer and urea. The trial assesses cotton growth, yield, and nitrogen use efficiency across blend ratios.

Evaluate multiple potassium fertilizer rates in cotton to optimize yield while minimizing potassium leaching into Florida water bodies. The trial quantifies plant growth, yield, and nutrient losses under varying K application rates to refine UF/IFAS recommendation guidelines.

Characterize the nitrogen release patterns of controlled-release fertilizers in dryland cotton using mesh bag trials. Data will help refine timing and rates for CRF applications.

The Florida Stakeholder Engagement Program (STEP) promotes the adoption of science-based Best Management Practices (BMPs) in cotton production through farm management competitions. The program highlights input use efficiency and profitability while also supporting outreach and education.

An annual large-plot cotton demonstration trial with seed partners Deltapine™, NexGen™, PhytoGen™, and Stoneville™ to evaluate new hybrids. We publish variety evaluation reports at the end of each season to guide growers in seed selection
