Optimizing Maize Yield, Nitrogen Efficacy and Grain Protein Content under Different N Forms and Rates

This study aims to evaluate the efficacy of nitrogen (N) forms: ammonium, nitrate, and urea on maize performance, N uptake use efficiency, grain protein content. The experiment was laid out as a split-plot with whole plot factor being three fertilizer treatments subplot four levels (0, 25, 50, 100 kg ha?1) replicates. Plant tissues were analyzed for total uptake. Grain stover yields determined at maturity. highest (62 cm) plant height (at vegetative stage) recorded in nitrate treatment. yield (2.9 t plots that received nitrate.
