Abstract: Agroforestry consists different diversity of plants and has a unique potential of balancing the net carbon emissions as a sink and reservoir for CO2 at both above and below-ground. The objective of this study was to investigate woody species diversity, management, and the biomass carbon and soil organic carbon stocks of Parkland Agroforestry (PLA) in Nagelle Arsi, Central Rift Valley of Ethiopia. Three study kebeles (Aliwoyo, Ashoka and, Godeduro) representing lowland, midland and ...
Abstract: The selection and use of appropriate Agroforestry tree species to maintain a sufficiently high nutrient supply to meet crop needs remains a major challenge of nutrient management under low input farming systems. Therefore, research on C. macrostachyus, F.vasta and E.abyssinica foliage litter quality as it relates to decomposition and nutrient release has become very important. A study was conducted to determine the rate of decomposition and nutrient release pattern from foliage lit...
Abstract: Parkland agroforestry woody species are prominent features in many landscapes worldwide, and their ecological, social and economic importance is widely acknowledged. Farmers have different objectives for retaining trees on their farm. This study was conducted to assess woody species diversity and evaluate the effect of selected tree species on sorghum yield components. For woody species inventory in the farmland with diameter at breast height (DBH) ≥5 cm were identified and measu...
Abstract: The study was conducted to investigate the effects of Acacia tortilistree in farmland on some selected soil physicochemical properties, and maize grain yield in Gursumdistrict, Eastern Hararghe, Oromia, Ethiopia. For the experiment of soil physicochemical properties, two factors: distance from tree trunk with three levels (under canopy, edge of canopy and out of canopy) and soil depth with two levels (0-20cm and 20–40cm depth) with factorial arrangement in RCBD replicated six tim...
Abstract: Modern beekeeping development is considered as a potential area to enhance the income of smallholder farmers by the Ethiopian government. To this end, special emphasis has been given to research and extension activities on the modern beekeeping practice at different scales. However, scientific evidences on participation, it`s utilization and its impact on the household income in Wonchi district were not documented. Therefore, this study was conducted to identify the factors that de...
Abstract: Wheat market in Dembecha district experienced in poor market linkage, disproportional benefit share, and inadequate market supply and market alternatives. This study was aimed to analyze value chain actors’ interaction and their role, wheat market structure-conduct and performance, factors affecting market supply and market outlet choices of smallholder wheat producers in Dembecha district of West Gojjam zone. The study used cross-sectional data collected from a sample of 130 far...
Abstract: Shade based coffee agroforestry systems have a considerable contribution to support biodiversity. Yet assets and limits of their contribution are insufficiently documented. Understanding the diversity and management of shade trees are important to maintain the balance of productivity and biodiversity conservation in human made landscapes such as coffee agro-ecosystems. The objective of this study was to assess tree species diversity, preference and management in small holder coffee...
Abstract: Agroforestry is accompanies different diversity of plants and has a unique capacity of balancing the net carbon emissions as a sink and reservoir for carbon dioxide at both above and belowgrou nd. The objective of this study was to investigate woody species diversity and carbon stock in coffee-based homegarden agroforestry in the Dellomenna District of Bale Zone, Ethiopia. Three study kebeles (Wabaro, Erba and, Chiri) were selected purposively. In each selected kebele, two sites we...
Abstract: Efficiency is an important factor for increasing productivity which leads to increase in market supply to achieve the goal of food security. In economics where resources are scarce and opportunities to use new technologies are limited, increasing efficiency remains the most reasonable means to raise productivity without necessarily developing new technologies or increasing the resource base. Low agricultural production efficiency or inefficiency rises because of failure of market. ...
Abstract: Homegarden agroforestry is commonly defined as a land use system involving deliberate management of multipurpose trees and shrubs in intimate association with annual and perennial agricultural crops and invariably livestock within the compounds of individual houses, the whole tree-crop, and animal unit are being intensively managed by family labor. The aim of this study was to investigate diversity and composition of homegardens agroforestry (HGAF) and its benefits for rural househ...

Abstract: Among several agroforestry practices in the east Hararghe of Ethiopia, Parkland agroforestry practices are common. However, the beneficial effect of tree species on soil properties is very scarce to be used for improved agricultural productivity in the eastern part of the country including study area. Therefore, the study was conducted with the objectives of investigating the impact of parkland trees on the soil physical and chemical properties within and outside the trees canopy; ...
Abstract: Homegarden is a land use system involving deliberate management of multipurpose trees and shrubs in intimate association with annual and perennial agricultural crops and invariably livestock within the compounds of individual houses. The high diversity of species in HG has wide socioeconomic and agro-ecological roles. Recently, there has been a decline in yields and income earnings from homegardens. These declines required a strategic plan that will enhance the balancing of the pro...
Abstract: Agroforestry is integrated land use systems where by woody perennials and herbaceous crops and/ animals are grown on a land management unit. The study attempted to evaluate the degree of factors and major problems influencing adoption of agroforestry practice among smallholder farmers of the district. In Wombera district, agroforestry technologies adoption and woody species distribution have not been extensively researched and introduced to smallholder farmers for long period of ti...
Abstract: This study was aimed to analyze technical efficiency of potato production by smallholder farmers in Dinsho district, Bale zone of Oromia region. The study used a cross sectional data obtained from a field survey using structured questionnaire from a random sample of 149 smallholder potato producers in the study area. The hypothesis test result showed that Cobb-Douglas production function was found to satisfactorily fit the data. A Cobb-Douglas stochastic frontier production analysi...
