Abstract: Tannery industry considered to be one of the polluting industries in case of water, soil and air due to the deferent types of chemicals used in transforming hide to leather. The study was conducted in order to determine the concentration of heavy metal of Chromium, Iron, Zink, Nickel, Manganese, Lead, Copper and Cadmium and particle size distribution of tannery solid waste and tannery dumping site soil. The sample was selected purposively and analyzed for the presence of heavy meta...
Abstract: Chickpea (Cicer arietinum L.) is a mulit important legumes in Ethiopia; however, despite of all the multi benefits of chickpea, its productivity has remained low in Ethiopian agriculture than the attainable yield (5 tons/ha) under improved and good management condition. Reasonable seed yield in chickpea could be achieved by using improved genotypes with appropriate agronomic practices. The investigation of improved genotypes requires a good breeding program, which usually depends o...
Abstract: The diffusion of agricultural practices is shaped by the relationships among actors in the social systems and this influences the extent of their adoption by the farmers. The objectives of this study were to assess farmers’ social networks and their explicit role in the diffusion and adoption of selected Climate-smart agriculture (CSA) practices in Sheema District of Uganda. The mixed-methods approach including both qualitative and quantitative measurements to contextually collec...
Abstract: Soil acidity is one of the main factors that limit agricultural productivity in many parts of the world. Study was conducted at Southwest showa Ameya District on acidic soils collected from dominant crop fields of the four selected kebeles in South Westshowa Zone, Ameya District to determine the status, and extents of acidity, and determination of lime requirements to neutralize the acidity effects. The selected kebeles were Gulti Bola, Bero Salen, Dire Aroji, and Kechema Jiran. Fi...
Abstract: Production and productivity of common bean is decreased mainly by soil fertility depletion, inappropriate rate of poor nutrients availability and application without soil test, and inefficient crop response. Crop specific fertilizer recommendation is necessary for sustainable crop production. Accordingly, a field experiment was conducted during the main rainy season of 2019 to evaluate the effects of types and rates of blended fertilizers on selected soil chemical properties and yi...
Abstract: Ensuring food security for the ever-increasing world population has direct relation with management of lands resources that are vital for crop production. Inadequate information on soil fertility status and poor management practices are among the main constraints to crop production in Ethiopia. Wheat is one of the most important cereal crops in Ethiopia. Yield of this crop is low mainly due to low soil fertility. In Ethiopia, Urea and DAP (di-ammonium phosphate) are the only fertil...
Abstract: Climate change has higher impact on agricultural production by its effect flood, drought, crop pests and diseases. The main objective of study was to assess the determinants of farmers’ choices of adaptation strategies to climate change. Both primary and secondary data were used. A multistage sampling technique was used. This study depends on cross-sectional data. Descriptive statistics,weighted average index, principal component analysis and Multivariate Probit model were used. ...
Abstract: Black cumin (Nigella sativa L.) is an annual spice used for flavoring of food, cosmetics and other industrial products, besides oleoresins and essential oils are valuable sources for health care used for medicinal purposes in Ethiopia. However, variety development was started recently and mainly dependent on introduction of breeding materials. As first step for the improvement of the crop, this study was conducted to assess the genetic variability and to estimate the association of...
Abstract: Providing detailed up-to-date and site-specific soil information to the beneficiaries at watershed level is essential to solve local problems restricting agricultural production. Site-specific characterization and classification of soils that provide detailed information on soil properties are vital in designing appropriate management strategies for sustainable development in agriculture and natural resources management. The present study was carried out to characterize the soils f...
Abstract: Soil resource inventory through characterization provides an insight into the potentials and limitations of soils for agricultral production. Soil fertility, on the other hand, is one of the most important factors controlling the yield of crops. However, a detailed study on soil resources characterization and soil fertility assessment based on the understanding of the soil system are not available for the most part of Ethiopia. With the cognizance of this fact, the present study wa...
Abstract: Soil characterization and classification is an important tool for identifying the most appropriate use of land as well as for sustainable utilization of the precious soil resources. Field survey and soil laboratory analysis were carried out to characterize selected morphological and physicochemical properties and classify the soils in Adele subwatershed of east Hararghe Zone, Ethiopia. Three representative pedons were opened at three topographic positions (upper, middle, and lower)...
Abstract: Salt affected soils are known to occur in vast areas of the arid and semi arid regions of the world. Reports indicated that nearly 11million hectare of soils in Ethiopia is salt affected and Abundance of soil with saline sodic property in Amibara irrigated farms is becoming a threat to crop productivity. As part of the solution to such problem soils, combine application of gypsum and farmyard manure has not been investigated well in the area. Therefore study was conducted at Werer ...
Abstract: Land degradation by soil erosion is a wide spread and serious phenomenon throughout the Ethiopian highlands causing significant loss of soil fertility, loss of productivity and environmental degradation. Thus, estimation of soil loss and identification of critical area for implementation of best management practice is central to success of a soil and water conservation program. This research has, therefore, been carried out to evaluate soil erosion risk in the study area so as to e...

Abstract: The present study was undertaken to investigate optimization of media in vitro propagation of sweet orange cultivar from Washington, Valencia and tanjelo orange explants. The explants were collected from three sweet orange cultivars. The result indicated the highest shoot response from Washington orange cultivar with maximum shoot proliferation rate (99.75%), shoot number per explant (3.10), shoot length (10.70cm), leaf number per explants (12.50) after three weeks of culture. In a...
