Abstract: Rain-fed agrarian reported as the backbone of the Rwandan economy has been severely affected by prolonged droughts and climate change impacts, resulting in severe food insecurity. In the Eastern Province, adoption of mono-cropping (MnC) system at dissent driven by the CIP may critically worsen the rain-fed agricultural gains against of mixed cropping (MxC) systems in drought conditions. Therefore, this study aimed to analyze and compare SOC stocks, simulated maize biomass and grain...
Abstract: This study was carried out in Kulkullessa Sub-Watershed of Goro Gutu District in Eastern Ethiopia to assess the effects of climate smart SWC practices and slope gradient on selected physicochemical properties of the soil and the soil's organic carbon stocks. The farmland conserved by SB, BT and GS five years after construction with two slope gradients (15-20%) and (21-30%) was selected. Twenty-four composite soil samples were collected from a depth of 20 cm and tested in the Harama...
Abstract: Any study concerning agricultural use of the soil resources has to begin with the characterization, genetic assessment and classification of the soils since these aid to identify constraints and potentials of soils that play great role in the exchange of knowledge among agricultural experts. The soil resources of East Hararghe, due to different environmental factors, especially due to the strongly rugged topographic condition and anthropogenic influences over a long period of time,...
Abstract: Site specific soil studies that include survey, characterization and classification at large scale are necessary to identify the production potentials and constraints that may limit agricultural Production and thereby to make site specific appropriate recommendations to solve agricultural problems based on the spatial variability of soil properties. The present study was conducted with the objective of characterization, classification and mapping soils of Hate Leman micro-watershed...
Abstract: Declined soil fertility is one of the main constraints to improve food production in Ethiopia and inadequate information about soil fertility in the study area. To replenish impoverished soils, site and crop-specific studies of soil fertility parameters are required to devise appropriate suggestions for site-specific balanced fertilizer recommendation and soil fertility management in the study area. With this milieu, this study was initiated to assess soil fertility, quantify nutri...
Abstract: The Decline in soil fertility due to nutrient depletion is a concern for low-input crop production in most parts of Ethiopia. Therefore, the objective of this study is to investigate the effect of vermicompost combinations with NPS fertilizer on soil physicochemical properties, Mungbean yield and yield components in Amibara district, middle awash, Ethiopia. The study was conducted at Werer Agricultural Research Center using mungbean under irrigated conditions. Experimental treatmen...
Abstract: This study was conducted to evaluate the effect of water restriction on physiological and blood parameters of Afar rams under arid climatic condition at Kalu District, Southern Wollo Zone, Amhara Regional state, Ethiopia. Eighteen healthy, 1.5 years old and 23-24 kg of live weight afar rams were randomly assigned in to three water restriction treatment groups with six rams each. The experiment was conducted during 4 seasons (viz. dry and wet season and the tests were carried out ov...
Abstract: Currently, climate variability and change has been recognized as a greatest global challenge facing humans being and their socio-economic activities. Rwanda like other developing countries has experienced climate variability and change, which declined agricultural productivities results into decreased national and household food security. To adapt to the changing climate, farmers need a transformation in their farming practices and adopt various practices that sustainably increase ...
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...
