MODELING THE IMPACT OF CLIMATE CHANGE ON MAIZE (Zea mays L.) PRODUCTION AND CHOICE OF ADAPTATION PRACTICES IN EASTERN ETHIOPIA

Abstract: Maize is the second most important cereal crop in eastern Ethiopia. However, climate change and variability is affecting its productivity in the region. Thus, studies that included survey, climate data analysis, and field experiment were therefore conducted with five objectives: 1) to assess smallholder maize farmers’ perception of climate change, their current adaptation options, and factors affecting their use of adaptation options in eastern Ethiopia; 2)to analyze past and pro...

Abstract: The purpose of this study was to assess on farm wheat landrace/ varieties) in Yem Special Woreda. A farmer based cross-sectional descriptive study was designed to assess on farm diversity of wheat landrace in Yem special woreda. A multi-stage sampling procedure was used in selection of agro-ecological zones, kebeles, and wheat growing farmers. Three kebeles from highland and two kebeles from midland agro-ecological zones were purposively selected. A total of 178 sample wheat growin...

INFLUENCE OF SOIL ORGANIC MATTER AMENDMENTS ON POPULATION DYNAMICS OF Aspergillus flavus AND ANTAGONISTIC MICROBES, AND ON AFLATOXIN CONTAMINATION OF GROUNDNUT IN MALAWI

Abstract: The study evaluated the effects of soil organic matter amendments on temporal dynamics of populations of A. flavus and antagonistic microbes, and on aflatoxin contamination in groundnut under field conditions in Malawi. The study also investigated the implications of rainfall on populations of the microbes. Treatments included commercial organic fertilizer applied at the rates of 0.2, 0.4 and 0.6 t ha-1; and farmyard manure at rates of 2.5, 5.0 and 7.5 t ha-1, while an untreated pl...

ASSESSMENT AND EFFECTS OF FERTILIZER AND IRRIGATION LEVEL ON MAIZE (Zea mays L.) PRODUCTIVITY AT BOLOSO SORE DISTRICT, SOUTHERN ETHIOPIA

Abstract: Maize productivity under irrigation is affected by several factors including climate, soil and water management, quality of water and soil, and levels of irrigation and fertilizer application. This study consisted of four objectives to (1) analyze rainfall and temperature variability and change, (2) assess farmers' preferences for soil and water management practices, (3) assess the quality of water and soil, and (4) determine the effects of fertilizer and irrigation levels on maize...

SEED GERMINATION AND EARLY SEEDLING GROWTH RESPONSE OF SELECTED SORGHUM (Sorghum bicolor L. Moench) UNDER VARYING SALINITY CONDITION

Abstract: Plant growth is adversely affected by salinity as a result of the disruption of certain physiological processes that lead to reductions in yield quality. Thus, this study was conducted to assess the potential for salt tolerance of the sorghum variety during germination and early seedling growth. The experimental treatments were six sorghum varieties and 4 NaCl concentration levels (0, 60, 120 and 180mM). The experimental design was a completely randomized design in factorial combin...

EFFECTS OF CROTON COMPOST ON SELECTED SOIL PHYSICOCHEMICAL PROPERTIES, YIELD AND YIELD COMPONENTS OF FRENCH BEANS (Phaseolus vulgaris L) IN LAIKIPIA EAST, SUBCOUNTY, KENYA

Abstract: Soil fertility depletion in smallholder farms is the fundamental biophysical root cause for declining per capita food production in Sub-Saharan Africa. Climate change exacerbates the problem of poor soil health. The combined use of mineral and organic fertilizers in ways that are adaptable to local conditions has the potential to achieve efficient nutrient use and result in improved yields for staple food crops. Despite multiple efforts made by the government of Kenya and internati...

COMPARATIVE ANALYSIS ON ROLE OF FRUIT TREE-BASED AGROFORESTRY AND MONOCULTURE IN ADDRESSING CLIMATE CHANGE CHALLENGES IN SOFI DISTRICT, HARARI REGIONAL STATE, ETHIOPIA

Abstract: The effects of climate change have hit the agriculture sector in Africa hard. Making adjustments to adapt to the changing environment is critical for countries like Ethiopia, whose primary source of income is subsistence agriculture, which is heavily reliant on rainfall. As a result, establishing context-specific adaptation approaches is crucial for reducing the adverse effects of climate change. This study was conducted at Sofi district, Harari Regional State, Ethiopia, to compare...

Dairy Production Practices and Milk Quality Assessment of Smallholder Dairy Farmers in Kombolcha Woreda of East Hararghe Zone, Oromia Region, Ethiopia

Abstract: The study was conducted to assess dairy production practices, milk composition, and microbial quality of smallholder dairy farms in Kombolcha Woreda, East Hararghe Zone, Oromia Region, Ethiopia. The study was undertaken in purposely selected three rural Kebeles of Kombolcha Woreda (Bilisuma, Tula, and Sibilu) where dairy Farmers from each Kebele were also purposely selected. A sample of households with at least one lactating cow was selected for interview using a simple random samp...

PRODUCTION PRACTICES, MILK YIELD AND COMPOSITION OF URBAN AND PERI-URBAN DAIRY CATTLE OF DEBRE-MARKOS TOWN, ETHIOPIA

Abstract: The study was conducted to assess the production practices, milk yield and composition, and to identify constraints and opportunities. The study was conducted in urban and peri-urban areas of Debre-Markos, east Gojjam zone. Four kebeles from each production system were randomly selected based on production potential and accessibility. A total of 120 respondents (15 from each kebeles) who owned local and cross breed cows were selected randomly. Data were collected using semi-structu...

EFFECT OF CLIMATE VARIABILITY ON DAIRY PRODUCTION AND ADAPTATION STRATEGIES AMONG PASTORALISTS IN GABILEY DISTRICT, SOMALILAND

Abstract: Climate variability is causing the greatest environmental, social and economic threats to all of humanity and across borders in many nations. The purpose of this study was to analyse long term climate variability and explore effects of climate variability on dairy production and identify the existing adaptation strategies in Gabiley district, Somaliland. To achieve the objective appropriate data was collected from 119 household heads from three sample villages, which were selected ...

IMPACTS OF CLIMATE VARIABILITY ON SELECTED CROP PRODUCTION: THE CASE OF BABILE DISTRICT, EAST HARARGHE ZONE, OROMIA REGIONAL STATE, ETHIOPIA

Abstract: This study was conducted to assess climate variability and its impacts on selected crop production in Babile district. To achieve the objective, primary data was obtained using questionnaire, focus group discussion and key informant interviews whereas secondary data were acquired from different published and unpublished documents from various offices of the district. The study also used rainfall and temperature data (1997 – 2016).out of 4875 household heads founds in the selected...

Performance and Carcass Quality of Broier Placed on Pro-Vitamin A Cassava and Sweet Cassava-Based Diets

ABSTRACT--- This experiment was carried out to determine the performance and carcass quality of broilers placed on pro-vitamin A cassava and sweet cassava-based diets using maize-based diet as control. The results show that daily weight gain of birds placed on maize-based diet (19.67g) was statistically higher (p0.05) among themselves. The average daily feed intake of the maize- based diets (54.07g/day) was significantly higher (p0.05) between each other. The feed conversion ratio of 2.75...

Effect of thermal and alkali treatment on Pterocarpus Angolensis (Mukwa) wood flour

Abstract: Environmental friendly pre-treatment of fibre has been lately adopted by many researchers worldwide but not fully understood. Although various chemical modifications of fibre through several chemical treatments have been explored, but less has been done on lower sodium hydroxide (NaOH) concentrations. This paper investigated the effect of thermalization at 115 C and lower NaOH of concentrations (1, 3 and 5) effect on mukwa wood flour as a way of minimizing chemical impact on possib...

Advances in nanoscale study of organomineral complexes of termite mounds and associated soils: A systematic review

Abstract: Termite mounds are replete with natural nanoparticles, and they vary in physicochemical, geochemical, mineralogical, and biological properties from the adjoining soils. Although termite mounds have wide ecological and environmental roles including soil formation, faunal and vegetation growth and diversity, organic matter decomposition, geochemical exploration, water survey, treatment of underground contamination, thermoregulation, gas exchange, and global climate change, their nano...
