Improved management strategies are needed to increase yield production and quality. The study aimed to determine suitable cultural practices for improved corn production. Experiments were set up at Verona and Stoneville, Mississippi, from 2020 to 2022. Treatments included row configurations (single and twin-row), plant populations (79,000 and 99,000 seeds ha-1), and six combinations of nutrients with or without fungicide. The nutrients evaluated were two nitrogen rates 235 and 314 kg N ha-1, phosphorus 45 kg P ha-1, potassium 112 kg K ha-1, sulfur 22 kg S ha-1, and zinc 11 kg Zn ha-1, and fungicide at 272 ml ha-1. In trial 1 (Addition), nutrients were added incrementally, whereas in trial 2 (Deletion) nutrients were withheld in a stepwise manner. Within nutrient treatments, results were erratic among years and sites. Overall, producers must find a balance in terms of yield and profit by taking soil testing and fertilizer prices into consideration.
