Soil specific maize response to N and P may provide guidelines for improving nutrient management. Three replicates of N and P fertilizer combinations (N

) were arranged in randomized complete block design on Plinthic Acrisol (PA) and Gleyic Plinthic Acrisol (GPA) in Ghana. Treatment effects on maize plant height and yield parameters were assessed. Plant height differed consistently with N
