Declining soil fertility and dependence on inorganic fertilizers threaten sustainable wheat production in Ethiopia. A three-year field experiment at Adet Agricultural Research Center evaluated the effects of integrating vermicompost (VC) with NP fertilizer on bread wheat productivity, soil fertility, and economic returns. The experiment used a randomized complete block design with five VC rates (0, 3, 6, 9, and 12 t ha-1) and three NP levels (0, 50%, and 100% of the recommended rate). The VC × NP interaction significantly affected biomass and grain yield. The highest biomass (6,859.6 kg ha-1) and grain yield (4,125.5 kg ha-1) were obtained with 9 t ha-1 VC plus 50% NP. Vermicompost also increased soil organic carbon. This treatment produced the highest net benefit (ETB 192,305.9 ha-1) and marginal rate of return (240.3%). Integrating VC with NP fertilizer enhanced wheat productivity, improved soil fertility, and increased economic returns under Ethiopian conditions.
