Abstract:
Efficient utilization of Nutrient will help boost crop yield in the face of rapidly increasing population and food insecurity. This study evaluates the effects of varying nitrogen and zinc rates on growth and yield of maize in Abaji, Federal Capital Territory of Nigeria. Four Nitrogen levels (0 kg N/ha, 40 kg N/ha, 80 kg N/ha and 120 kg N/ha) were evaluate with two Zinc levels (0 kg Zn/ha and 2 kg Zn/ha). The experimental factors were combined with a Factorial in Randomized Complete Block Design (RCBD). Nitrogen was applied as Urea while Zn was applied with Zinc Sulphate (ZnSO4). Phosphorous was applied with Single Super Phosphate (SSP) at the rate of 60 kg P2O5/ha and potassium was supplied with Muriate of Potash (MOP) at 60 kg K2O/ha. Result shows that Nitrogen application rate of 80 kg N/ha gave the optimum yield in the study area and was recommended for adoption along with other sustainable soil nutrient management practices.
