Balanced fertilization based on indigenous soil nutrient status and crop demand is imperative for efficient nutrient management and enhancing crop yield. A field experiment was conducted at Kersa District, Southwestern Ethiopia during 2019/20 cropping season to determine the effects of nutrient combinations on nutrient recovery fraction, physiological efficiency and economic benefits of maize. The treatments includes T1 [Control], T2 [NP], T3 [PKS (-N)], T4 [NKS (-P)], T5 [NPS (-K)], T6 [NPK (-S)], T7 [NPKS], T8 [NPKSZn (-B)], T9 [NPKSB (-Zn)] and T10 [NPKSZnB]. The treatments were arranged in randomized complete block design (RCBD) with four replications each. Maize grain yield, total (grain + straw) nutrient concentration and economic of fertilizer use were analyzed during experimentation. The data were analyzed using SAS 9.0 version software. The results indicated that grain yield, biomass yield and nutrient recovery fractions of maize responded significantly due to different mineral fertilizer combinations. Accordingly the maximum grain yield (8702.6kg ha-1) and biomass yield (20.1tha-1) were obtained from T8 treated with (N120 P40 K40 S20 Zn5 kgha-1), while the lowest grain yield (2028.5 kgha-1 and 2793.5 kgha-1) and biomass yield (5.6 tha-1 and 7.2 tha-1) were recorded from control and N-omitted plots, respectively. Compared with NP and control plots, application of NPKSZn produced 76.6% and 29.8% yield advantages, respectively. The maximum apparent recovery fraction of each nutrient was obtained from application of N120 P40 K40 S20 Zn5 kgha-1. Economic analysis showed, this treatment generate the highest net benefit of 80,364 ETB ha-1 (1$=42Birr) with acceptable marginal rate of return (MRR) (486.35%). Therefore, incorporating Zn with in major macronutrients (NPKS) is more important to increase maize production in the study area.
