Abstract: In sub-Saharan Africa, plant nutrient deficiency, due to nutrient mining, is a major growth limiting factor for crop production. As a result, some soils become non responsive to Rhizobial inoculation. In an effort to find out possible correction, a field experiment was carried out on-farm, during 2016/17 growing season, at Gondar Zuria woreda in Tsion and Denzaz Kebeles to evaluate the effect of Rhizobium inoculation, S and Zn application on yield and yield parameters, nodulation, ...
Abstract: Potato is an important food security and cash crop in eastern Hararghe Zone. However, the productivity of the crop is constrained by low soil fertility and poor fertilizer management practices. Therefore, a field experiment was conducted at Haramaya watershed in Haramaya District, Eastern Ethiopia; during the 2014 using irrigation. The main objective of the study was to assess the effects of integrated nutrient management on potato growth, yield and yield components and selected ph...
Abstract: Bread wheat is an important food security and cash crop in Ethiopia, particularly in the Bale and Arsi highlands. However, the yield of the crop is constrained by poor soil fertility management practices. Therefore, a field experiment was conducted during the 2015 main cropping season at Selka Kebele of Sinana District in Bale zone of Oromia Regional State, southeastern Ethiopian with the objective of investigating the influence of biochar, farmyard manure, and mineral nitrogen fer...
Abstract: The ostriches (Struthio camelus) are the largest flightless birds (Ratites) in the world and characterized by their heavy weights and large wings. They are also among the common birds that inhabit the park areas as feeding and nesting sites.This study was conducted to assess and document the population status and feeding ecology of Ostrich in Abijata-Shalla Lakes National Park, West Arsi Zone of Oromia Regional State. A cross sectional research design was used to collect informatio...
Abstract: The Colobus monkey (Colobus guereza) is black and white in color, distributed mainly in forests and savanna woodlands. They are easily be identified by a combination of facial features and tail morphology from other primates; they are also among ideal subjects to study animal abundance and feeding ecology. A cross sectional survey was conducted to provide and document baseline information regarding the population size, feeding ecology and threats to C. guereza in Beteria Forest, Aw...
Abstract: Faba bean (Vicia faba L.) is one of the earliest food legumes of the world used as source of high protein for human and animal consumption. In Guna wereda no studies were conducted on faba bean genetic variability and this study is designed to fill this gap. The study was designed to reveal the genetic variability and using phenotypic traits, fifteen accessions were laid out in a Randomized complete block designs (RCBD) with three replications. Each block consisted of 15 genotypes....
Abstract: Soil salinity is a major environmental issue threatening agricultural productivity worldwide. Therefore, screening for salt tolerant varieties is the most important and overcomes the salinity problems and treated with different saltconcentration.thus, this study aimed to study five selected tomato varieties collected from Awash Malkasa agriculture. An experiment was conducted at xii Haramaya University School of Biological Sciences and Biotechnology laboratory and a greenhouse expe...
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...
