Nitrogen use efficiency is one of the key issues in farming and fertilization, it is defined as the amount of product produced per unit of resource used. A split plot arrangement in randomized complete block design with four replications was used to compare the yield, nitrogen use efficiency and some quality characters of three maize (Zea mays L.) cultivars. The analysis of variance revealed that both nitrogen and maize cultivars were significantly differences in yield, nitrogen use efficiency, crude protein and crude fibre content in both seasons. This study revealed that improving nitrogen use efficiency can help in optimizing nitrogen use in maize.
