Abstract: Faba bean production is a common practice in Limu Bilbilo areas. However, its productivity is affected and limited by poor soil fertility and lack of alternative technologies such as application of optimum phosphorus fertilizer for different faba bean varieties. Limited studies on the role of P on faba bean varietal yield and yield components are reported in Ethiopia, especially in the case of Limu Bilbilo conditions. Studies on the effect of phosphorus (P) fertilization are genera...
Abstract: Agricultural practices of smallholders with low external and internal inputs fluxes cause the risk of depleting soil nutrient stocks, seriously threatening future agricultural production potentials in Ethiopia. To curb soil fertility depletion in these areas, it needs quantification of fluxes that are responsible for nutrient import into and export out of the farming system. The objective of this study was to quantify nutrient fluxes, pools and NPK balances at farm and field scales...
Abstract: Zinc and iron are among the essential plant nutrients required in relatively small quantities for plant growth. Deficiencies of Zn and Fe have been reported in soils of Tigray, Ethiopia. The deficiencies of Zn and Fe in the soil system affect both plant growth and the nutrient contents in the grain of cereals for human consumption. This study was developed to (1) assess the status of Zn and Fe in leaves of teff and bread wheat in relation to soil contents and properties in agro-eco...
Abstract: The study was conducted on Gemechis natural forest, West Hararghe, Oromia Regional state, Ethiopia with the objective of determining the floristic composition, structural analysis and regeneration of wood plant species. Systematic sampling was used to collect vegetation data. Accordingly,50 sampling quadrats of 20 m x 20 m were laid along six line transects at every 50 m interval within which five 5 m x 5 m small quadrats were laied to sample woody species with 2cm. Fifty one (51) ...
Abstract: Soil survey and land evaluation are pertinent for effective utilization of natural resources and deliver site-specific soil management recommendations to the end-users. There is, however, limited information on the properties, constraints and potentials of soil resources in Hintalo Wajerat district of Northern Ethiopia. The purpose of this study was to (1) characterize, classify and map soils (2) generate soil quality index and analyze its spatial distribution (3) assess and map so...
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: Tomato is an important cash crop grown by smallholder farmers as well as private investors in Raya Valley, Northern Ethiopia. However, the yield of the crop has been low due to poor soil fertility status and use of improper rates of fertilizers. Three independent field experiments were conducted to investigate the response of tomato to fertilizers at Raya Valley for two consecutive seasons during 2016/17 using drip irrigation. The first field experiment was carried out to investiga...
Abstract: Soil acidity is one of the soil chemical degradation problems affecting soil productivity in the Ethiopian highlands. So, amendment of these soils is of paramount importance to enhance their productivity. This study was conducted during the 2017 cropping season to determine the effects of lime and phosphorus levels on selected soil properties and bread wheat yield on acidic soils of Pawe Agricultural Research Center Banja sub-station in Awi Zone of Amhara National Regional State. T...
Abstract: Soil fertility depletion is one of the major limiting factors for wheat yield reduction in the study area. As a result, inorganic fertilizers are commonly supplied to the crop. However, continuous and sole use of inorganic fertilizers may lead to deterioration in soil chemical and physical properties. Therefore, the study was conducted to investigate the integrated use of organic and inorganic fertilizers on selected soil properties and yield of wheat, which was conducted in Lume d...
Abstract: Low availability of P is among the major problems limiting crop production in the highlands of Ethiopia, including the study area, where soil acidity is a major problem. Information on chemical forms and rate of P adsorption, which can be used as a basis for P fertilizer recommendation, is not available in Cheha and Dinsho districts, souhthern highlands of Ethiopia. The current study was, therefore, conducted to evaluate the amount and distribution of P forms as influenced by lime,...
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...
