POTASSIUM DYNAMICS AND THE RESPONSE OF TEFF AND CHICKPEA TO POTASSIUM FERTILIZATION ON VERTISOLS OF EAST GOJJAM, NORTH WEST ETHIOPIA

Abstract: Vertisols cover large areas which are widely used for agriculture in Ethiopia. The chemical and physical properties of Vertisols are influenced by the type of clay minerals which appears to be mainly smectite, with different proportions of other clays such as kaolinite, illite and vermiculite. Potassium (K), a major plant nutrient with in the soil, exists in different forms. Assessing the fractions of K is important to have knowledge on the supplying power of soil K for plant nutri...

IMPACT OF LANTANA CAMARA L. ON HERBACEOUS SPECIES DIVERSITY AND SOIL CHARACTERISTICS IN BABILE DISTRICT, EASTERN ETHIOPIA

Abstract: This study assessed the impact of Lantana camara invasion on herbaceous species diversity and soil physio-chemical properties in Babile District, Eastern Ethiopia. To collect the vegetation data, 1mx1m plots were laid down in each 60 selected lantana individuals under and outside the cover in four directions. From each plot, a soil sample was taken from 0-15cm depth after removing litter from the soil surface for Soil physiochemical analysis. Three herbaceous species (Panicum color...

IMPACTS OF Parthenium hysterophorus L. ON SELECTED SOIL CHEMICAL PROPERTIES AND ITS POTENTIAL DISTRIBUTION UNDER CLIMATE CHANGE SCENARIOS IN ETHIOPIA

Abstract: Parthenium hysterophorus has become a major environmental, social, and economic threats in Ethiopia. Therefore, identification and mapping of suitable habitats and impacts on soil chemical properties are vital to design future management strategies. A total of 36 soil samples were collected from P. hysterophorus invaded and non-invaded sites. A total of 1,352 P. hysterophorus occurrence records and 19 bioclimatic variables were collected from different sources. ANOVA was conducted ...

IMPACT OF IRRIGATION ON CROPPING PATTERN, FARM INCOME AND HUMAN LABOR EMPLOYMENT IN SOFI DISTRICT OF HARARI REGION, ETHIPIA

Abstract: In Ethiopia about 93 percent of cultivated area is rain fed and crop production primarily depends on rainfall. Present study was conducted in rain fed Sofi-District of Harari Region. The objectives of the study were to identify factors affecting participation of farmers in irrigation scheme and impact of irrigation on cropping pattern, farm income and human labor employment. The study was based on 260 sample house holds (130 participants in irrigation schemes and 130 non-participan...

CLIMATE VARIABILITY, IMPACTS ON MAIZE (Zea mays L.) YIELD, AND SMALL HOLDER FARMERS’ PERCEPTION AND ADAPTATION STRATEGIES IN WEST BADAWACHO DISTRICT OF HADIYA ZONE, SOUTHERN ETHIOPIA

Abstract: Climate variability affects crop productivity at both global and local scales, and adaptation of agricultural practices against this variability helps to translate perception of the farmers to decision-making process. This study was initiated to analyze climate variability, examine its effect on maize productivity, and assess perception and adaptation strategies of smallholder farmers to climate variability in West Badawacho District. Climate and crop data from 2000-2019 were colle...

PHENOTYPIC DIVERSITY, GENETIC VARIATION AND ASSOCIATION OF MORPHO-AGRONOMIC AND BIOCHEMICAL TRAITS IN OKRA [Abelmoschus esculentus (L.) Moench] GENOTYPES IN ETHIOPIA

Abstract: Okra is considered a minor crop and has not given research attention in Ethiopia. Therefore, a key strategy to adapt to a changing climate is the development and promotion of underutilised crop species. Thus, this research was conducted to assess the genetic diversity, genetic variability, heritability, genetic advance and association of traits of okra genotypes using morpho-agronomic traits and biochemical contents. A total of 36 okra genotypes (27 landraces and 9 introduced comme...

WOODY SPECIES DIVERSITY, REGENERATION STATUS AND CARBON STOCK ALONG AN ELEVATION GRADIENT IN FURI FOREST, CENTRAL ETHIOPIA

Abstract: This thesis was conducted in Furi forest in central of Ethiopia. Biodiversity is organized along altitudinal gradient in different layers as altitude determines climate distribution. Plant diversity is one of the major groups of biological diversity. Plant diversity can be affected by living and nonliving factors. The overall objective of this study was to assess composition, diversity and structure, regeneration status of woody species and total carbon stocks along an elevation gr...

SOIL CHARACTERIZATION, CLASSIFICATION AND QUALITY ASSESSMENT IN KERSA SUB-WATERSHED, EASTERN ETHIOPIA

Abstract: Knowledge about types of soils and the status of their quality is needed for developing sound land use planning and soil management decision for enhancing crop productivity. However, such information is lacking in Kersa sub-watershed in eastern Ethiopia where the current study was conducted. The objectives of this study were, therefore, to 1) characterize and classify soils of the study area, 2) determine soil quality indicators using minimum data set and calculate soil quality ind...

Supplementation of Cowpea (Vigna unguiculata) Hay, Wheat Bran and Their Mixtures to Begait Sheep Fed Grass Hay in Western Tigray, Ethiopia: Effects on Growth Performance, Carcass Characterist

Abstract: Twenty five yearling male Begait sheep with initial body weight (BW) of 28.02± 1.49 (mean ± SD) were used to evaluate the effect of supplementation of cowpea (Vigna unguiculat) hay (CPH), wheat bran (WB) and their mixtures to sheep fed grass hay (GH) on feed intake, digestibility, average daily gain (ADG), carcass characteristics, skin quality and economic feasibility. Experimental sheep were blocked in to five blocks based on initial body weight and randomly assigned to the five...

Development and Evaluation of Straw-Based Densified Complete Feed Blocks on the Productive Performances of F1 Freisian-Borena Crossbred Dairy Cattle in the Central Highlands of Ethiopia
