EVALUATION OF SOIL ACIDITY AND EFFECTS OF AMENDMENTS ON SELECTED SOIL PROPERTIES AND YIELD OF MAIZE (Zea mays L.) IN EBANTU DISTRICT, WESTERN HIGHLANDS OF ETHIOPIA

Abstract: In highly weathered and leached soils, acid soil infertility is a major limitation to crop production. Three major experiments were conducted under laboratory, greenhouse, and field conditions to assess soil acidity status of surface soils under three land use types (forest, cultivated, and grazing lands), evaluate the effects of lime, vermicompost (VC), and chemical phosphorus (P) fertilizer on selected soil properties, and investigate the effects of the three amendments on select...

MODIFIED METHOD FOR PREDICTING PHOSPHATE DESORPTION KINETICS AND DYNAMICS FROM SOILS AND ITS RELATION WITH PLANT GROWTH

Abstract: Phosphorus (P) limits plant growth particularly in very strongly acidic soils. P availability to plant is a functional concept rather than measurable quantity. This research work was intended to synthesize nanocomposite material that can monitor soil P desorption kinetics and dynamics and relate to P uptake by maize (Zea mays L.). The binary oxide Fe-Al composite system, both in a crystalline and amorphous form was synthesized by sol-gel evaporation method and characterized by XRD,...

Soil Fertility Mapping of Agamsa Watershed in Habru District, Northeastern Ethiopia

Abstract: Declining soil fertility is the major challenge to boost crop production in Ethiopia. As a result, assessment of soil fertility status and mapping can help to design site specific soil fertility management techniques. Therefore, this study was conducted at Agamsa watershed in Habru District, Northeastern Ethiopia, with the objectives of assessing the soil fertility status of the watershed and mapping the spatial distribution of the selected soil fertility parameters. Field survey w...

Response of Faba Bean (Vicia faba L.) to Rhizobium Inoculation and Potassium Fertilizer Application on Nitisols at Wolaita Sodo, Southern Ethiopia

Abstract: Lack of effective indigenous soil rhizobia and low soil fertility including potassium deficiency are the major production constraints that limit the potential yield of faba bean in the study area. Hence, field experiment was conducted to evaluate the effect of Rhizobium inoculation and potassium fertilizer application on nodulation, yield components and yield of faba bean; to determine the potassium use efficiency; and to evaluate the economic feasibility of the treatments for faba...

SOYBEAN (Glycine max L.) RESPONSE TO LIME AND VERMICOMPOST AMELIORATION OF ACIDIC NITISOLS OF ASSOSA, NORTH WESTERN ETHIOPIA

Abstract: Acidic soils limit the production potential of crops because of low availability of basic cations and excess of hydrogen (H+) and aluminium (Al3+) in exchangeable forms. In the western part of the country such as Assosa and Wellega, soil acidity is a well-known problem limiting crop productivity. A field study was conducted to assess the effects of lime, vermicompost and their combinations on selected soil physic-chemical properties and responses of soybean grown on acidic Nitisols...

Assessment of Physicochemical Properties of Soil Under Different Land Use Types at Wuye Gose Sub-Watershed, North Shoa Zone of Oromia Region, Ethiopia

Abstract: ASSESSMENT OF PHYSICOCHEMICAL PROPERTIES OF SOIL UNDER DIFFERENT LAND USE TYPES AT WUYE GOSE SUBWATERSHED, NORTH SHOs loamy sand while it was sandy loam in homestead land and forest land. The BD ranged from 1.51 (GL) to 1.13 g/cm3 (HL) and TP varied 57.25 (HL) to 43.04% (GL). Soil water content at FC was ranged from (45.18) in homestead to (36.35%v) in grazing land. Permanent wilting point, in %v, was high (16.99) in homestead and forest to low (8.49) in grazing and cultivated land...

EVALUATION OF SELECTED SOIL PHYSICOCHEMICAL PROPERTIES ACROSS LAND USE TYPES AND SOIL DEPTH IN SUMBE SUB-WATERSHED OF WEST SHOWA ZONE, CENTRAL ETHIOPIA

Abstract: Soil quality is very much affected by land use and also soil depth. A study was conducted at Sumbe sub-watershed, located in the Toke Kutaye District of West Showa Zone of Oromia region, with the objective of evaluation of selected soil physicochemical properties under different land uses and soil depth. The results revealed the existence of spatial variation in soil properties among land use types and with soil depth in a given land use. Relatively higher silt content (47.50%) was...

QUANTITATIVE TRAIT VARIATIONS THROUGH CHEMICAL MUTAGENESIS IN SESAME ( Sesamum indicum. L).

Abstract: Sesame (Sesamum indicum L.) is considered to be an ancient oil seed crop to generate high quality edible oil having nutritional and health related value but still at an early stage in breeding. Its chromosome number is 2n=26 and it belongs to the Pedaliaceae family and having significant economic value globally as well as in Ethiopia.With the objective of broadening the gene pool of sesame an experiment was conducted in the genetics and molecular biology laboratory as well as agric...

ASSESSMENT OF SOIL EROSION RISK USING RUSLE MODEL IN ANALEMO WEREDA, 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...

SPATIAL VARIABILITY OF SOIL PROPERTIES, LIME REQUIREMENT DETERMINATION, AND RESPONSE OF BARLEY AND WHEAT TO APPLICATIONS OF LIME AND PHOSPHORUS FERTILIZER IN CENTRAL HIGHLANDS OF ETHIOPIA

Abstract: Knowledge of spatial variability of soil properties assists in decision making towards selection of appropriate management options pertinent to specific contexts. Liming acid soils is one of the available intervention options to amend soil acidity which can increase soil pH and alleviate Al toxicity to plants and thus maintain a suitable condition for growth of a variety of crops. Appropriate rate of lime and P fertilizer are therefore an important strategy on improving crop growth...

CHARACTERIZATION AND CLASSIFICATION OF SALT AFFECTED SOILS OF AMBO-COBA AREA UNDER GOLINA WATERSHED IN RAYA KOBO VALLEY, AMHARA REGION, ETHIOPIA

Abstract: It is known that all soils contain a certain amount of soluble salts and exchangeable sodium, magnesium, potassium, and calcium. However, when the concentration of either of them is excess, it will interfere with many soil processes including plant growth and the effects depend on the degree of concentration and type of plant. It is, therefore, with this understanding that a study was conducted with the objective to classify and characterize the salt affected soils of Ambo-coba in ...

Abstract: Information on the Effect of Slope Gradient and Management Practices in soil chemical and physical properties is key for predicting the relative response of soils to application of fertilizers and putting forward appropriate management practices. The present study was, thus, conducted to assess the selected chemical and physical properties of the soils as affected by slope gradient and management practices at the Dawja Watershed in Enebse Sar Midir District of East Gojjam Zone, Eth...

RESPONSE OF FABA BEAN (Vicia faba L.) VARIETIES TO PHOSPHORUS FERTILIZER RATES IN LIMU BILBILO DISTRICT OF ARSI ZONE, SOUTH EASTERN ETHIOPIA

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...

NUTRIENT FLOWS AND BALANCES UNDER CROP-LIVESTOCK FARMING SYSTEM OF YABALA, BEDELE DISTRICT, SOUTHWESTEREN OROMIA, ETHIOPIA

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...
