The experiment was conducted to refined profitable NPK fertilizer rate for maize production on Tanchera series (Ferric Lixisol, FAO, 2006) in the Sudan savanna agro-ecological zone of Ghana. RCBD design with four replications was used. Treatments evaluated were N = 0, 40, 80, 120, 160; P = 0, 45, 90 and K = 0, 45, 90 kg/ha. Results showed significant N rate effect on grain yield, benefit cost ratio and gross return (P ≤ 0.01). P and K did not show significant effect among these parameters. Application of nitrogen from 80-120 kg/ha may be recommended for improve grain yield and gross return of maize production on Ferric lixisol. Due to poor nature of soils, application of P and K up to 45 kg/ha may also be recommended for maize production.
