A field experiment was conducted to determine the optimum level of nitrogen and its effects on maize growth and yield. Five nitrogen levels 0, 62, 124, 186 and 248 kg ha-1 were used with two varieties Composite-17 and Sultan. The results showed that the nitrogen levels influenced significantly the various growth and yield components, like number of leaves per plant, number of days taken to tasseling, silking and maturity, biological yield, stalk yield, grain weight per cob, number of grains per row, per cob and grain yield. Varieties were also significantly affected by different nitrogen levels. The highest grain yield of 6.36 t ha-1 was obtained with 248 kg N ha-1.
