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: 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: 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...
Abstract: Soil acidity is one of the major yield-limiting factor for crop production worldwide, particularly on highly weathered and leached tropical soils. Different reports have indicated that there is significant soil acidity coverage in Ethiopia. Particularly, in the western part of the country, soil acidity is a well-known problem limiting crop production and productivity. As part of the solution to such problem in soils, combined application of lime and VC on maize has not been investi...
Abstract: Wheat is one of the most important cereal crops produced in Ethiopia. However, its production is low mainly due to low soil fertility and poor soil fertility management practices. Field experiment was conducted during 2019 cropping season in Chencha district, Southern Ethiopia to determine the effect of NPSB rates on wheat yield and yield parameters and assessing the effect of the aforementioned fertilizer on selected soil properties. Treatments used for the field experiment were; ...
Abstract: Climate variability and change is one of the global challenges facing human beings and their socio-economic activities. The negative impacts are being felt in many parts of Kenya especially in decadence of the agricultural productivity resulting into decreased national and household food security. To adapt to the changing climate, farmers’ need a paradigm shift in their farming practices and adopt practices that sustainably increase agricultural productivity and enhance their res...
Abstract: Depletion of soil fertility due to soil erosion and nutrient mining farming system leads to decline in soil productivity and subsequently crop yields. This study was initiated to assess soil fertility status and to determine micronutrient concentration in the tissues of maize and sorghum grown at Daro Labu district, Eastern Ethiopia. Twelve maize and twelve sorghum growing fields from four peasant associations (PA) were selected purposively. Field survey was conducted to collect ge...
Abstract: Although forest biosphere reserve interventions are crucial for sustaining forest ecological functions and services, there is a dearth of information on whether the biosphere reserves in the southwest of Ethiopia contribute to the offset of the three intermingled contemporary challenges, including biodiversity loss, climate change, and livelihood sustainability. This dissertation therefore aimed to quantify (i) land use/land cover (LULC) dynamics and its driver in Sheka Forest Bios...
