The Collaborative Role of Non-Synthetic Fertilizers on Production of Faba Bean (Vicia faba L.) in Ethiopia's Central Highlands, Ejere District

This study sought to determine how non-synthetic fertilizers collaborated to produce faba bean in the 2019–20 and 2021–2022 cropping seasons in agricultural settings in the Ethiopian district of Ejere. The treatments were laid out in a randomized complete block design with three replications. The collected data were subjected to analysis of variance by SAS statistical platform version 9.3. Means were compared with the Least Significance Difference (LSD) at a 5% probability level. To compute the economic advantage of the intervention, farm get prices of inputs and outputs were considered and marginal rate of return (% MRR) was work out for each treatment, and values ≥100 was set as profitable in absolute terms. The mean outcome of the two years’ worth of data analysis showed that there was substantial (p ≤ 0.05) difference in all parameters among the treatments at Ejere. At Ejere, the treatments (FB-17 + 0.76 ton ha-1 VC), (FB-17+ 0.57 ton ha-1 VC), (0.76 ton ha-1 VC) and (FB-17+ 0.38 ton ha-1 VC) yielded the highest mean GYs (3582kg ha-1), (3535kg ha-1), (3430 kg ha-1) and (3234 kg ha-1), respectively. However, the results of the partial budget analysis showed that the treatments (FB-17) and (FB-17 + 0.57 ton ha-1 VC) had the greater marginal rates of return 7218% and 1148%, respectively. These treatments are thought to be very good candidates for more testing in farmers' fields across various aggro-ecologies in order to determine which ones are the best substitute non-synthetic fertilizers for faba bean production in Ethiopia's Nitisol zones.
