Where, NPSB = blended fertilizer of nitrogen, phosphorus, sulfur and boron; N = nitrogen; UGY = unadjusted grain yield; AGY = adjusted grain yield; GFB = gross field benefit; NPSB = NPSB Cost/NPSB application cost; NC/NAC = nitrogen cost/nitrogen application cost, TVC = total variable costs; NB = net benefit, MRR = marginal rate of return; ETB = ethiopian Birr; D = dominated treatment.
