An experiment on the response of maize (Zea mays) to different levels of nitrogen and phosphorus was conducted during the summer season of 2021 at Experimental Farm, M. S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Odisha. The experiment was laid out in a split-plot design comprising four levels of nitrogen (0, 60, 120, 180 kg N/ha) and three levels of phosphorus (0, 40, 80 P₂O₅/ha) with three replications. The maize hybrid sharp was sown on February 24th, 2021. The application of 180 kg N/ha registered significantly higher growth (plant height and leaf area index) than other treatments. The grain and stover yield and yield attributes in the former treatment were comparable with 120 kg N/ha and significantly superior to other treatments. Application of 80 kg P₂O₅/ha recorded significantly higher growth and yield attributes, grain yield, and stover yield.
