Abstract: Faba bean (Vicia faba L.) is believed to be one of the earliest domesticated legumes next to chickpea. It is an important pulse crop produced all over the world for both foods, feed & it serves as a cheap source of protein The main objective of this activity is to demonstrate improved faba bean technology through a cluster-based crop production approach. Large scale demonstration of faba bean technology is conducted at Wolmera, district and sheger city administration for two years (2021/22-2022/23). Districts, kebeles, and farmers are selected based on potential in faba bean production and farmers' willingness to implement technologies, with woreda agricultural office. 32 farmers and three improved varieties of Wolki, Dosha, and Numan used. 24.85 qts of seed is used to cover 12 hectares of land with a full package. The demonstrate result revealed that the mean, advantage and percent yield increase of the improved technologies across locations shows. The first year (2021/22) yield result showed that variety Wolki at Wolmera in Robgebeya kebele gives a mean grain yield of 28.5 qt/ha which is higher than the national and regional average yield 21.22 and 23.31 qt/ha respectively. In the second year (2022/23) faba bean LSD result showed that the average grain yield harvested across the districts is 27.3 qt/ha greater than the national, regional and zonal average mean grain yield. The maximum grain yield 38.9 qt/ha and an average yield of 32.5 qts/ha was obtained from Robegebeya Kebele. The data indicates that the actual yield from LSD is generally higher than the national and regional average yield in the country. Therefore, the study indicates that maximum faba bean yield can be achieved in fertile soil conditions, controlling diseases like faba bean gall diseases, and applying full crop recommendation packages.

Abstract: Soil fertility status under different land use systems has been verified to be useful for soil fertility management practices and the efficient utilization of limited land resources. The study was conducted from 2021 to 2023 in the Yabello District to assess soil fertility status under different land use systems and mapping of selected soil fertility parameters. Consequently, based on soil factors such as parent materials, topography, climate, and geomorphology, Yabello District was divided into 87 sampling units. A total of eighty-seven (87) sample mapping units were identified, and composite soil samples were collected and analyzed for physicochemical properties at the Yabello and Batu Soil Research Centers. For soil parameter analysis, laboratory standards were followed. Based on laboratory results, the data was subjected to interpolation using ArcGIS 10.8 software (ordinary kriging), was used to predict values for unsampled locations and to map the whole district. Accordingly, soil texture was categorized as sandy clay loam in forest, cultivate and grazing lands, and sandy clay in shrub lands. Available phosphorus ranged from medium to high in forest land, medium in shrub and grassland, and low in cultivated land. Soil pH was categorized as slightly acidic to neutral in forest land, neutral in grassland, and slightly alkaline in cultivated and shrub lands. Organic carbon ranged from low to high in forest land, medium in grassland, and low to medium in cultivated areas. Therefore, further research should focus on correlating and calibrating soil test with crop responses to develop site-specific fertilizer recommendations and optimal application rates.

Abstract: Despite Kenya's policy commitment to Climate-Smart Agriculture (CSA) and progressive reforms in agricultural extension, significant gaps remain in ensuring equitable access to and effective services, particularly in arid and semi-arid regions. This study examines the delivery and perception of CSA-responsive extension services among smallholder farmers in Tharaka Nithi County, focusing on three key dimensions: inclusion (gender and disability), feedback mechanisms, and provider type (public versus private). Utilizing a cross-sectional mixed-methods approach with 418 respondents, the study integrates quantitative analysis with qualitative insights to evaluate access to extension services and CSA adoption. The findings indicate that private sector-led extension services reached a more diverse group of farmers and were more strongly associated with CSA adoption than public sector-led services. Although gender and disability alone did not yield statistically significant differences in access, their combined effect approached significance, indicating the presence of intersectional barriers. Feedback mechanisms also influenced outcomes: field visits and community meetings effectively promoted CSA adoption, particularly for farmers with disabilities, whereas Short Message Service (SMS) messaging had limited impact. Education and farming experience emerged as significant factors facilitating adoption. Overall, the findings highlight the limitations of conventional, top-down extension systems and underscore the necessity for more participatory, inclusive, and locally adapted approaches. This study advocates for a transition toward a multi-actor, learning-centered CSA-responsive extension model to ensure that climate resilience strategies equitably reach and benefit all farmers, especially those situated at the last mile of service delivery.
