Abstract: Low soil fertility and lack of site specific fertilizer recommendation to replenish declining soil fertility have been the critical challenges to boost maize production in Ethiopia. This study was conducted during 2017 cropping season in Bako Tibe district of west Shewa Zone to assess soil fertility of study area. One hundred geo-referenced soil samples were collected from 1 km x 1 km sub grid generated within 10 km x 10 km main grid. Field experiment was also conducted in this gri...
Abstract: Soil acidity is one of the major soil chemical constraints which limit crop productivity in the high rainfall regions of Ethiopia in general and in the study area in particular. In view of this, a field experiment was conducted at Negasa area in Guto Gida district on farmer’s field to study the effect of lime and vermicompost amendment on selected soil properties and yield and yield components of wheat (Triticum aestivum L.), grown during 2016 main cropping season. The factors st...
Abstract: Poor soil fertility is the major constraint affecting the productivity of malt barley in the highlands of Ethiopia. Malt barley responds well to growth limiting nutrients in the soil, especially nitrogen. A field experiment was conducted at Welmera District during 2017 cropping season to determine soil fertility status and the optimum nitrogen application rates for malt barley production without affecting grain quality. The treatments were a factorial combination of five N rates (0...
Abstract: Land use types and the associated managements are the main causes for decline of soil fertility and agricultural productivity. A study was conducted to investigate the selected soil physico-chemical properties under cultivated and grazing lands at Fincha Debsa Watershed. Two land use types (cultivated and grazing) representative for the watershed were selected. Soil samples were collected from (0-20 and 20-40 cm) from three sites of each land use which were adjacent to each other a...
Abstract: Medicinal plants have been used for centuries to treat diseases. This study was carried out to screen the phytochemical composition and evaluate the antibacterial activities of crude leaf extracts of Tanacetum parthenium (feverfew) against dental pathogenic bacteria. T. parthenium is a medicinal plant which belongs to the family Asteraceae. Mature leaves of this plant were collected from Haramaya University and were shade dried and ground to powder. The crude extracts were prepared...
Abstract: A Study on woody plant diversity and structure were conducted on Telet Forest in Sayint District, South Wollo Zone of Amhara Region, Ethiopia. Sixty four main quadrats of 20m × 20m with which five small quadrats of 5mx5m were systematically laid along transects. In each main quadrat, all tree/shrub and saplings and seedlings of woody species within the subplots were counted and recorded. Tree height of plants was also measured using a meter-stick so as to categorize plants into he...
Abstract: The study was conducted in Getta district with the objective of assessing home garden practices and plant species diversity. From purposively selected sample Kebeles', random sampling method and selection of key informants related to indigenous knowledge of home garden was used. Sample plots of 10mx10m laid randomly on homgarden and woody plant species (DBH>2cm) was recorded. 5 small plots (2mx2m) one from the center and one from each corner of big plot was laid to record herbaceou...
Abstract: In Ethiopia, salt affected soils are prevalent in the Rift Valley and lowland areas. Beans, which grow in different parts of Ethiopia, are salt sensitive. This experiment was conducted with the objective of screening bean varieties: namely Tumsa, Gora and Gachena for salt tolerance by the use of some agronomic traits such as days to seed germination, seedling shoot and root length, seedling shoot and root fresh weight, seedling shoot and root dry weight were measured in the laborat...
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....
