Abstract: The rate, time and method of nitrogen fertilizer application mainly influence the growth, development, yield of the crop. Growth attributes like number of leaves per plant, dry matter accumulation, leaf area index vary with dose of applied nitrogen. Quality parameters such as protein content, total sugar content, minerals were affected by different nitrogen levels. Total minerals in maize grains were increased with high nitrogen rate. The yield components of maize (cob length, no. of kernels per cob, cob weight, kernel weight on cob, grain weight) were also affected with nitrogen dosage. As nitrogen is an integral part of chlorophyll molecule as well as grain nitrogen uptake is also effected by nitrogen element. This review emphasized the role of nitrogen on growth, development and production of maize and also focuses on method and rate of fertilizer application for higher yield. In addition to this, performance of nitrogen on different growth and yield components.
