Abstract: This study aimed to analyze the soil, biological and economic responses of faba bean to the combined effects of organic fertilizers in farm settings located in the Ethiopian district of Kersa Malima in 2019/20 and 2020/21 cropping seasons. 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 average outcome of the two years' worth of data analysis showed that there was substantial (p ≤ 0.05) difference in all parameters among the treatments in the district. Treatments (FB-17 + 0.76 ton ha-1 of vermicompos) and (FB-17 + 0.57 ton ha-1 of vermicompos) demonstrated relative first and second superiority in average TN (%), available P (ppm) and OC (%) at the district. Treatments (FB-17 + 0.76 ton ha-1 of vermicompost), (FB-17 + 0.57 ton ha-1 of vermicompost), and (FB-17 + 0.38 ton ha-1 of vermicompost) yielded the highest mean grain yields (3588 kg ha-1), (3316 kg ha-1), and (3216 kg ha-1) in the district of Kersa Malima. However, treatment FB-17 at this district had higher marginal rates of return 5624% according to the results of the partial budget analysis. To find the finest organic fertilizer substitutes for faba bean production in Ethiopia's Vertisol zones, such as the Kersa Malima district, these treatments are considered to be excellent candidates for additional testing in farmers' fields across a variety of agro-ecologies.

Abstract: A field experiment was carried out during the 2020–2021 growing season to examine how the sweet potato responded to various doses of organic and inorganic fertilizer. The treatment included three levels of farmyard waste and four levels of nitrogen fertilizers (0, 40, 70, and 100 kg N ha-1) (0, 5and 10 FYM t ha-1). The experiment was performed three times and set up using a Randomized Complete Block Design in a factorial layout. Software called SAS (version 9.3) was used to examine the data. The findings showed that the majority of the growth, yield, and yield components were significantly (P 0.01) impacted by the application of N and farmyard manure fertilizers. The highest and lowest vine lengths measured were 160.23 and 112.17 cm, respectively. Other measurements included shoot fresh weight (1009.6 and 109.8 g hill-1), shoot dry weight (141.35 and 61.6 g hill-1), days of bud sprouting (13.27 and 6.34), days of physiological maturity (147.8 and 119), number of branches per plant (7.30 and 4.28), harvest index (0.36 and 0.28%), biomass yield (1009.2 and 579.7), tuberous storage tuber diameter (22.5 and 15.6 cm), total tuber yield (22.45 and 7.05 tha-1), marketable tuber yield (21.85 and 7.65 tha-1), unmarketable tuber yield (3.25 and 0.31 t/ha), marketable storage tuber number (3.2 and 0.83), and un marketable tuber number (0.38 and 0.02) were obtained from 10t ha-1farmyard manure plus 100 kgha-1 N fertilizer. However, the above-mentioned factors were countered by the number of branches per plant, the quantity of unmarketable tubers, and the yield of unmarketable tubers. In conclusion, the findings showed that the application of inorganic nitrogen fertilizer along with farmyard manure might improve the growth, production, and yield components of sweet potatoes. To get more trustworthy data, though, additional research must be done in various environments and at various times of the year while taking fertilizer rates for nitrogen and FYM into account.
