Abstract: The common bean cultivation and usage is most widely practiced in the study areas, where it is mostly used for home consumption. However, its production and productivity is constrained by several factors. Among the factors, foliar diseases are the major biotic factor that affects bean productivity in the region. Hence, to provide a valuable input which contributes in solving this production constraint, the present study was conducted with the objectives of studying the relative importance of major foliar diseases of common bean. The assessment was done in Yabello, Teltelle, and Elwaye districts. Four kebeles were selected per district and the assessment was done at 4-7km intervals. A simple random sampling method was used to collect disease samples which were performed at 5 points in a W-shaped fashion per field with 1m2 quadrat. The survey result revealed angular leaf spot (ALS), common bacterial blight, anthracnose, common bean mosaic virus, and leaf rust were the major common bean diseases in Borana. Of which ALS was the most distributed disease over the study areas. With, the prevalence of ALS was 96.77%. Of these fields 91.67% had a disease severity index of more than 50%. For such a high intensity and distribution of ALS, weed infestation, low tillage frequency, and crop density were found to be the most associated agronomic factors. Moreover, the present study indicated that there is high potential to combat the disease in the area using resistant varieties and some agronomic measures such as proper weeding, tillage, plant spacing and crop rotations.

Abstract: Bamboo is the fastest growing perennial plant. Once the rhizome-root system is well established, new bamboo shoots attain full height and diameter within 2–3 months. Bamboo provides goods and services useful to mankind. It is a source for food, fodder, furniture, building materials, paper, particle board, energy, and medicine. Therefore the study was conducted to evaluate adaptation of six introduced bamboo species with local variety as control. Activity was conducted at Negele Arsi and Kofale districts. Among the introduced species four species namely Dendrocalamus diannanensis, Dendrocalamus fuminesis, Dendrocalamus asper and Dendrocalamus yunnanis were significantly different (p<0.5) from the rest species in terms of height, DBH, RCD, Internodes length and number of nods at Negele arsi. High survival rate was also recorded for those species. While at kofale district only four introduced bamboo species (Dendrocalamus diannanensis, Dendrocalamus fuminesis, Dendrocalamus asper and Dendrocalamus yunnanis) were survived and Bambusa longinternode and Dendrocalamus barbatus were completely damaged due to extreme low temperature. Therefore the study and observation made showed clearly that Dendrocalamus diannanensis, Dendrocalamus fuminesis, Dendrocalamus asper and Dendrocalamus yunnanis were the most adapted species to the study environment and must be popularized and scaled up in the study area for further production.
