Abstract:
Faba bean (Vicia faba L.) is one of the earliest domesticated food legumes in Ethiopia and is now cultivated on large areas in many countries. It serves as an important role in the socio-economic life of the farming communities. It has an important place in the Ethiopian national diet and is consumed in various forms. However, the productivity of the crop is attributed by biotic and abiotic factors. Among the biotic factors diseases are the major ones. In addition to the previous major diseases, a recently reported gall forming faba bean disease has become a very serious disease that seriously affected faba bean production. As a result a survey was conducted with the objective of finding out the intensity of faba bean gall disease on major faba bean growing districts of North shoa zone of Oromia and Amhara regional states during the main cropping season of 2015. Random sampling was applied to select farm field in each district i.e. every faba bean field at interval of 5-10 km based on vehicle odometers following the main roads and accessible routes were assessed. In the selected fields, faba bean gall disease assessment was made along the two diagonals at five stops in (‘’X’’ fashion) using quadrants and data were collected from each stop. During the survey, a total of 126 fields were assessed, of which the disease was prevalent on 103 (81.75%) of the fields with mean incidence and severity of 46.52 and 39.17%, respectively. The disease intensity was varied with altitude, location and type of cultivars. The highest mean disease severity (44.74%) was recorded on altitude above 2800 m.a.s.l. while the least (28.96%) was recorded at altitudes below 2600 m.a.s.l. Local cultivars showed highest disease incidence (32.9%) and severity of (39.7%) than improved cultivar which was showed disease incidence and severity of 20% each
