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.

Abstract: Sinapis alba L is one of the most important bee forage species adapted to the highlands of Bale, which is well known for providing pollen and nectar to honeybees. Seed rate and row space are the most important parameters that play a great role in the growth performance of Sinapis alba. This study was conducted at the Sinana Agricultural Research Center, Bale Zone, and southeastern Oromia region, to evaluate the effects of seed rate and row spacing on the growth performance of Sinapis alba in the highland of Bale condition during the 2021 to 2023 main season. This study used RCBD with three replications and two treatments arranged in a factorial combination. The spaces between the plot & block were 1 m & 1.5 m, respectively. The plot size of each treatment was 1.2 m x 3 m (3.6 m2). The collected data was analyzed statistically by using ANOVA methods. Duncan's multiple range test and general linear model (GLM) tested the mean differences between treatments and within treatments. The highest number of secondary branches (13.87) was obtained by 15 cm row spacing. The highest number of pods/plant (94.16) was found when seeds were sown in 25 cm row spacing. Thirty cm row spacing produced the highest number of seeds/pod (3.66), and 15 cm row spacing produced the lowest number of seeds/pod (2.72). The highest seed yield (17.17 qt/ha) was produced when the seeds were sown in 20 cm row spacing. The highest pollen yield (0.85 gm) was produced by 20 cm row spacing, and the lowest (0.59 gm) was produced by 30 cm row spacing. The highest number of the secondary branches (13.07) was obtained by the application of 10 kg/ha. A higher number of pods/plant (101.65) was produced by the application of 8 kg of seeds. A higher number of seeds/pods (4.08) was produced by the application of 10 kg of seeds/ha. 10 kg of seeds/ha produced a higher seed yield (16.75 Qt/ha), and 14 kg of seeds/ha produced a lower seed yield (12.4 Qt/ha). The highest thousand-seed weight (4.06) was obtained by the application of 10 kg/ha. Using an appropriate seed rate (10 kg/ha) and row spacing (20 cm) is of paramount importance to increasing the seed of Sinapis alba.
