“…Moderately resistant variety, late planting, and chlorothalonil or mancozeb fungicide have been recommended in Ethiopia for chocolate spot management [20,21]. For faba bean gall disease, crop rotation, Bayleton fungicide spray, and seed treatments have been documented for its management [22,23]. However, management of faba bean diseases using fungicides is criticized for their expensive cost and their efects on the environment and human and animal health.…”

A field study was conducted to evaluate faba bean varieties for yield and yield components and disease reactions in the Lay Gayint district during the 2020 and 2021 cropping seasons. Six faba bean varieties, including local, were arranged in a randomized complete block design with three replications. The crop and disease data were collected, and the disease severity was assessed five times in 7 and 10 days intervals using the disease rating scale for chocolate spot and faba bean gall disease, respectively. The combined analysis variance showed significant P<0.01 differences among faba bean varieties in agronomic traits, disease severity, and area under the disease progress curve. The variety Numan had a higher chocolate spot (46.52%) and faba bean gall (40.46%) disease severity. The area under the disease progress curve (AUDPC) of the chocolate spot was higher on local (1292.85%-days). For faba bean gall, a higher AUDPC value (994.08%-days) was calculated from the Numan variety. The lowest severity of chocolate spot (27.37%) and faba bean gall (21.02%) was assessed from the variety Gora, and this variety also had the lowest chocolate spot AUDPC. The variety Gora and Ashebeka provided the highest grain yield (21988 kg·ha−1) and (20624 kg·ha−1), respectively. The results of the correlation analysis also indicated that the highest yield was associated with lower disease occurrence. In conclusion, varieties Gora and Ashebeka are found to be moderately resistant varieties to chocolate spot and faba bean gall disease than other varieties with higher yields, and these varieties are recommended for production in the study area and other similar ecologies.

“…This might probably be attributed to different biotic and abiotic factors. Of which the use of old and low yielding local cultivars and unavailability of high yielder improved varieties [2] and the newly emerged faba bean gall disease that causes up to complete crop failure in susceptible cultivars and under conducive prevailing conditions [1,2,18] were the most important factors.…”

Field experiment was conducted at Degam, H/Abote, D/Libanos, Jida and Wachale districts of North Shewa Zone, Oromia region, Central Ethiopia with the objectives of evaluating adaptable and best yield performing improved Faba bean varieties for further demonstration and scaling up during the main cropping season of 2020, 2021 and 2022. The experiment was conducted using randomized complete block design (RCBD) with three replications. In the experiment, thirteen improved faba bean varieties and one local control were used to evaluate their performance. Parameters like seed yield (qt/ha), 1000 seed weight in gram, number of pod per plant, number of seed per pod, plant height (cm) were measured to assess the actual field performances of different faba bean varieties. The data were analyzed by R software. Grain yield and most of yield components were significantly affected by main effect of variety, environment and interaction of variety and environment. The results revealed that there were significant (P < 0.01) variations between the varieties for yield. Higher yield was recorded on Welki and Ashebeka varieties while low yield was recorded from Tosha and Shalo. In addition the stability analysis indicated that as the mean of grain yield is more stable across locations as compared to other variety. Also, in this study it was found that there is 24.5 % and 19.1% increment of yield using of Welki and Ashebeka variety respectively as compared to local variety at the study area. Therefore, farmers located at the study area are recommended to use those varieties to increase faba bean production yield.

“…Australia, UK, and Germany are also among the largest faba bean producers after Ethiopia [7]. In highland areas of Ethiopia, faba bean is a major staple food crop among pulses [8] and the most vital legume crop after the staple cereals [9]. It is a dominant legume crop in area coverage and production than the other pulses in the country.…”

The diploid cool-season legume species, faba bean (Vicia faba L.), is one of the vital pulses for the people in the world as it maintains the sustainability of agriculture and provides nutrient-rich grains. Biotic and abiotic stresses are, however, challenging the faba bean production in many countries. The foliar diseases of faba bean are among the major constraints for the production and productivity of faba bean. Recently, a new foliar disease “Faba bean gall” caused by plant debris and soil-borne pathogen (Olpidium viciae K.) is rapidly spreading and causing high yield losses in Ethiopia. This review paper presents the distribution, impact, epidemiology, and biology of faba bean gall pathogen and principally illustrates how the application and investigation of the various diseases’ management approaches such as avoiding crop residues, crop rotation, intercropping, use of elicitors to induce host resistance, use of resistant genotypes, bioagents, compost teas, plant extracts, and lastly use of chemical fungicides could be important to control the faba bean gall disease underlying in faba bean.
