Abstract: Soil test based fertilizer recommendation concurrent to the actual limiting nutrients for a given crop helps to supply adequate and balanced plant nutrients for sustainable crop production without affecting soil health negatively. Blended NPSB fertilizer is a newly introduced fertilizer for crop production in the study area. However their optimum rate for maize crop production and their impact on selected soil property is not yet determined in the study area. Therefore a study was ...
Abstract: Low soil fertility is a prominent factor for low agricultural productivity, whereby inorganic fertilizers have become important inputs to overcome the problem. In Ethiopia, different blended fertilizer types are used without clearly identifying the production limiting nutrient of a specific crop for a specific soil type. The present study was designed to identify the most yield limiting nutrients for sorghum on Leptosols through nutrient omission trials, which was conducted in 2021...
Abstract: The productivity of shallot is low due to low soil fertility as one of many constraints. Thus this research was conducted to assess the effects of combined application of vermicompost (VC) and inorganic NPS fertilizer on bulb yield, yieldrelated traits, shelf life of shallot, soil physical and chemical properties for sustainable nutrient management without harming the environment. The field experiment consisted of four rates of NPS (0, 50, 100 and 150 kg NPS ha-1) and five VC rates...
Abstract: Changes in land use, particularly the transformation of natural ecosystems into managed agroecosystems under poor management practices, are widespread in Melka Gura Subwatershed in North Shewa, Ethiopia. Therefore, studying variations and status in soil properties across land uses is essential to knowing the extent and magnitude of soil degradation across different land uses and planning suitable soil management strategies. Due to this, the current study evaluated certain soil phys...
Abstract: Climate variability and change is increasingly threatening livelihoods and food security and in turn, the attainment of national development goals in Kenya. The declining productivity of agricultural production systems calls for a transformational change in farming practices to ensure sustainable and resilient agriculture. This study assessed smallholder farmers’ perception of climate variability and change, climate smart agricultural practices used by farmers to adapt to climate...
Abstract: Soil acidity is the main production constraint that reduces nodulation and productivity of soybean crop in Bako district, western Ethiopia. This study was carried out to determine the influence of blended NPS fertilizer, Vermicompost (VC), and Seed inoculation with Rhizobium bacteria on productivity of soybean (Glycine max. (L.)Merrill) and selected soil chemical properties. Factorial combinations of two Rhizobium strain (TAL-379) levels: uninoculated, inoculated, three vermicompos...
Abstract: Salinity is a major and increasing problem worldwide that needs to be addressed in order to increase agricultural production. The experimental materials were five selected green chili species, such as Capsicum annuum, Capsicum frutescence, Capsicum chinense, Capsicum baccatum, and Capsicum pubescence and four NaCl concentration levels (0, 60, 120 and 180mM) for laboratory and greenhouse experiments. The experimental design was a completely randomized design in factorial combination...
Abstract: Human-wildlife conflict (HWC) is regarded as an interaction between humans and wildlife that results in negative impacts on humans, animals, or the environment. The HWC has been a recurring problem in Ethiopia due to increased human population and competition for the declining resources. This study was conducted to assess and document the causes, impacts and management options of the effect of wild life on human in and around the study area. The study design was a longitudinal popu...
Abstract: The study was carried out in Hallideghie Wildlife Reserve, Afar National Regional State, Ethiopia with objectives to assess woody species diversity, vegetation structure and carbon stock potential of the reserve. Woody plant species diversity, vegetation structure and carbon stock potential of the study area undertaken in four vegetation type by using stratified sampling approach. A total of 12 horizontal transect lines were laid out in the four vegetation types and a total of 36 q...
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...
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...
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...
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...
Abstract: Climate smart agriculture is an approach that minimizes the adverse effects of climate change by increasing production, strengthening adaptation, and providing mitigation to smallholder farmers. This study was initiated to identify major climate smart agricultural practices adopted, analyze factors affecting the adoption of climate smart agricultural practices, and evaluate the impact of the adoption of climate smart agricultural practices on the annual income of smallholder farmer...
