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...

SOIL FERTILITY STATUSAND EFFECT OF NITROGEN RATES ON GRAIN QUALITY AND NITROGEN USE EFFICIENCY OF MALT BARLEY (Hordeum vulgare L.) VARIETIES AT WELMERA DISTRICT, CENTRAL HIGHLANDS OF ETHIOPIA

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...

SOIL PHYSICO-CHEMICAL PROPERTIES UNDER CULTIVATED AND GRAZING LANDS AT FINCHA DEBSA WATERSHED, OROMIA REGION, WESTERN ETHIOPIA

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...

EFFECT OF INTEGRATED SOIL FERTILITY MANAGEMENT ON SELECTED SOIL PROPERTIES AND YIELD OF BREAD WHEAT (Triticum aestivum L.) IN SINANA DISTRICT, ETHIOPIA

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...

ASSESSMENT OF HEAVY METALS CONCENTRATION IN TANNERY SOLID WASTE AND SOIL AT THE DUMPING SITE IN MOJO TOWN, CENTRAL ETHIOPIA

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...

ACIDITY STATUS AND LIME REQUIREMENT OF SOILS OF AMEYA DISTRICT, SOUTHWEST SHOWA, ETHIOPIA

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...

SOIL FERTILITY STATUS AND EFFECTIVENESS OF NP, NPS AND NPSB FERTILIZERS FOR WHEAT (Triticum aesticum L.) PRODUCTION AT GULTI BOLA IN AMEYA DISTRICT, SOUTHWEST SHOA, ETHIOPIA

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...

CHARACTERIZATION AND CLASSIFICATION OF SOILS OF TINIKE SUBWATERSHED IN EAST HARARGHE ZONE, OROMIA REGION, EASTERN ETHIOPIA

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...

CHARACTERIZATION AND CLASSIFICATION OF SOILS ALONG TOPOSEQUENCE IN ADELE SUBWATERSHED, EAST HARARGHE ZONE, ETHIOPIA

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)...

ASSESSMENT OF SOIL EROSION RISK USING RUSLE MODEL IN ANALEMO DISTRICT, SOUTHERN NATIONS, NATIONALITIES, AND PEOPLES’ REGION, ETHIOPIA

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...

RESPONSES OF ACIDIC SOIL AND MAIZE ( Zea mays L.) TO LIME AND VERMICOMPOST APPLICATION AT LALO ASABI DISTRICT, WESTERN ETHIOPIA

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...

SOIL FERTILITY AND MICRONUTRIENT STATUS IN TISSUES OF MAJOR CROPS IN DARO LABU DISTRICT, WESTERN HARARGHE ZONE, EASTERN ETHIOPIA

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...
