GENETIC VARIABILITY AND ASSOCIATIONS AMONG YIELD AND YIELD RELATED TRAITS OF CHICKPEA (Cicer arietinum L.) GENOTYPES AT WEST BADEWACHO DISTRICT, HADDIYA ZONE, SOUTH REGIONAL STATE OF ETHIO

Abstract: Chickpea (Cicer arietinum L.) is a mulit important legumes in Ethiopia; however, despite of all the multi benefits of chickpea, its productivity has remained low in Ethiopian agriculture than the attainable yield (5 tons/ha) under improved and good management condition. Reasonable seed yield in chickpea could be achieved by using improved genotypes with appropriate agronomic practices. The investigation of improved genotypes requires a good breeding program, which usually depends o...

THE ROLE OF SOCIAL NETWORKS IN THE ADOPTION OF CLIMATE-SMART AGRICULTURE PRACTICES IN SHEEMA DISTRICT, WESTERN UGANDA

Abstract: The diffusion of agricultural practices is shaped by the relationships among actors in the social systems and this influences the extent of their adoption by the farmers. The objectives of this study were to assess farmers’ social networks and their explicit role in the diffusion and adoption of selected Climate-smart agriculture (CSA) practices in Sheema District of Uganda. The mixed-methods approach including both qualitative and quantitative measurements to contextually collec...

ACIDITY STATUS AND LIME REQUIREMENT OF SOILS OF AMEYA DISTRICT, SOUTHWEST SHOWA, ETHIOPIA

Abstract: Soil acidity is one of the main factors that limit agricultural productivity in many parts of the world. Study was conducted at Southwest showa Ameya District on acidic soils collected from dominant crop fields of the four selected kebeles in South Westshowa Zone, Ameya District to determine the status, and extents of acidity, and determination of lime requirements to neutralize the acidity effects. The selected kebeles were Gulti Bola, Bero Salen, Dire Aroji, and Kechema Jiran. Fi...

EFFECTS OF TYPES AND RATES OF BLENDED FERTILIZERS ON SELECTED CHEMICAL SOIL PROPERTIES AND YIELD OF COMMON BEAN (Phaseolus Vulgaris L.) IN DEBUB ARI DISTRICT, SOUTHERN ETHIOPIA

Abstract: Production and productivity of common bean is decreased mainly by soil fertility depletion, inappropriate rate of poor nutrients availability and application without soil test, and inefficient crop response. Crop specific fertilizer recommendation is necessary for sustainable crop production. Accordingly, a field experiment was conducted during the main rainy season of 2019 to evaluate the effects of types and rates of blended fertilizers on selected soil chemical properties and yi...

SOIL FERTILITY STATUS AND EFFECTIVENESS OF NP, NPS AND NPSB FERTILIZERS FOR WHEAT (Triticum aesticum L.) PRODUCTION AT GULTI BOLA IN AMEYA DISTRICT, SOUTHWEST SHOA, ETHIOPIA

Abstract: Ensuring food security for the ever-increasing world population has direct relation with management of lands resources that are vital for crop production. Inadequate information on soil fertility status and poor management practices are among the main constraints to crop production in Ethiopia. Wheat is one of the most important cereal crops in Ethiopia. Yield of this crop is low mainly due to low soil fertility. In Ethiopia, Urea and DAP (di-ammonium phosphate) are the only fertil...

DETERMINANTS OF FARMERS’ CHOICES OF ADAPTATION STRATEGIES TO CLIMATE CHANGE: THE CASE OF GUANGUA DISTRICT OF AWI ZONE, AMHARA NATIONAL REGIONAL STATE, NORTHWESTERN ETHIOPIA

Abstract: Climate change has higher impact on agricultural production by its effect flood, drought, crop pests and diseases. The main objective of study was to assess the determinants of farmers’ choices of adaptation strategies to climate change. Both primary and secondary data were used. A multistage sampling technique was used. This study depends on cross-sectional data. Descriptive statistics,weighted average index, principal component analysis and Multivariate Probit model were used. ...

GENETIC VARIABILITY AND ASSOCIATION OF TRAITS IN BLACK CUMIN (Nigella sativa L.) AT DEBRE-ZEIT, CENTRAL ETHIOPIA

Abstract: Black cumin (Nigella sativa L.) is an annual spice used for flavoring of food, cosmetics and other industrial products, besides oleoresins and essential oils are valuable sources for health care used for medicinal purposes in Ethiopia. However, variety development was started recently and mainly dependent on introduction of breeding materials. As first step for the improvement of the crop, this study was conducted to assess the genetic variability and to estimate the association of...

CHARACTERIZATION AND CLASSIFICATION OF SOILS OF TINIKE SUBWATERSHED IN EAST HARARGHE ZONE, OROMIA REGION, EASTERN ETHIOPIA

Abstract: Providing detailed up-to-date and site-specific soil information to the beneficiaries at watershed level is essential to solve local problems restricting agricultural production. Site-specific characterization and classification of soils that provide detailed information on soil properties are vital in designing appropriate management strategies for sustainable development in agriculture and natural resources management. The present study was carried out to characterize the soils f...

SOIL SURVEY AND FERTILITY ASSESSMENT OF ARGO-GEDILALA SUBWATERSHED IN DUGDA DISTRICT, CENTRAL RIFT VALLEY OF ETHIOPIA

Abstract: Soil resource inventory through characterization provides an insight into the potentials and limitations of soils for agricultral production. Soil fertility, on the other hand, is one of the most important factors controlling the yield of crops. However, a detailed study on soil resources characterization and soil fertility assessment based on the understanding of the soil system are not available for the most part of Ethiopia. With the cognizance of this fact, the present study wa...

CHARACTERIZATION AND CLASSIFICATION OF SOILS ALONG TOPOSEQUENCE IN ADELE SUBWATERSHED, EAST HARARGHE ZONE, ETHIOPIA

Abstract: Soil characterization and classification is an important tool for identifying the most appropriate use of land as well as for sustainable utilization of the precious soil resources. Field survey and soil laboratory analysis were carried out to characterize selected morphological and physicochemical properties and classify the soils in Adele subwatershed of east Hararghe Zone, Ethiopia. Three representative pedons were opened at three topographic positions (upper, middle, and lower)...

EFFECT OF GYPSUM AND FARMYARD MANURE ON SELECTED PHYSICOCHEMICAL PROPERTIES OF SALINE SODIC SOIL, YIELD AND NITROGEN USE EFFICIENCY OF RICE (Oryza sativa L.) AT AMIBARA, ETHIOPIA

Abstract: Salt affected soils are known to occur in vast areas of the arid and semi arid regions of the world. Reports indicated that nearly 11million hectare of soils in Ethiopia is salt affected and Abundance of soil with saline sodic property in Amibara irrigated farms is becoming a threat to crop productivity. As part of the solution to such problem soils, combine application of gypsum and farmyard manure has not been investigated well in the area. Therefore study was conducted at Werer ...

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

The explants were collected from three sweet orange cultivars. The result indicated the highest shoot response from Washington orange cultivar with maximum shoot proliferation rate (99.75%), shoot number per explant (3.10), shoot length (10.70cm), leaf number per explants (12.50) after three weeks of culture. In a...

RESPONSES OF ACIDIC SOIL AND MAIZE ( Zea mays L.) TO LIME AND VERMICOMPOST APPLICATION AT LALO ASABI DISTRICT, WESTERN ETHIOPIA

Abstract: Soil acidity is one of the major yield-limiting factor for crop production worldwide, particularly on highly weathered and leached tropical soils. Different reports have indicated that there is significant soil acidity coverage in Ethiopia. Particularly, in the western part of the country, soil acidity is a well-known problem limiting crop production and productivity. As part of the solution to such problem in soils, combined application of lime and VC on maize has not been investi...
