A field experiment was carried out on Maize (Zea Mays L.) grown on a sand soil during 2017 season to assess implications of N rates and irrigation water on yield and water consumption. The design was a factorial randomized complete block involving two factors: Factor W: 3 irrigation treatments as % of an Etc of 6588 m³ ha^-1, i.e. 100% (W₁), 80% (W₂) and 70% (W₃). Factor N: 3 N rates  as % of  a recommended 310 kg N ha^-1,i.e.100% (N₁) ,80% (N₂) and 70% (N₃). Grain yields (Mg ha^-1) ranged from 2.80 (W₁N₃) to 4.48 (W₂N₂).Fertilizer N recovered in grains+stalks+leaves ranged from 5.4 % (W₂N₁) to 16.5% (W₂N₃). N use efficiency (kg grains kg^-1 N) was 6.3 (W₁N₂) up to 18.6(W₃N₁). Water utilization efficiency (kg grains m^-3 water) was 0.43 (W₁ N₃) to 0.84(W₃ N₃). High N and water use efficiency on sandy soils, must be by balanced combination water and N , and the general trend  showed 5270 m³ water and 248 kg N per hectare (representing 80% of officially recommended inputs of each)
