The aftermath of insurgency, climate change and poor soil fertility, necessitated the search for crops that can perform better within a short duration under the vagaries of environment. Thus, field experiments were conducted in 2014 and 2015 rainy reasons at the FAO/TCP farm, Adamawa State University Mubi, Nigeria to study the Performance of maize varieties (Zea mays L.) with different rates of Nitrogen fertilizer and cowdung. Treatments consisted of maize varieties [(Quality Protein Maize (QPM) and Extra Early White (EEW)], Nitrogen rates (0, 60 and 120 kg N ha-1) and cowdung rates (0, 1 and 2 t ha-1). In an experiment laid out in a split plot design, the varieties were assigned to the main plots and nitrogen with cowdung in a factorial combination assigned to the subplots and replicated three times. Data were collected on plant height, leaf area index, plant dried weight, days to 50% maturity and grain yield per hectare and analyzed using SAS system for windows. Result showed that EEW had the highest plants height, leaf area index and plant dried weight. Nitrogen at 120 kg ha-1 produced highest plant dry weight and grain yield. Similarly, cowdung at 1 t ha-1 gave highest plant height, leaf area index and early days to 50 % maturity. There were interactions between treatments on parameters measured. Base on the results, varieties were observed to perform very well, with EEW manifesting higher characteristics. Thus, Nitrogen at 120 kg ha-1 should be use in the cultivation and be complimented with 1 t ha-1 cowdung.
