The study was carried out from 2014-16d during cropping season with the objective of promoting Quality Protein maize demonstration which was conducted with active participation of farmer's in collaboration of wereda bureau of agriculture in three major maize potential kebeles namely Dawatebel, WajituHaribu and Hamusgebya under 19 demonstration plot...

Maize is the third most consumed cereal in the world and an important source of carbohydrates, making it an energy-producing food source. The main objective of this study was to demonstrate and promote the use of improved maize varieties for green ear production. Participatory action research was employed as the research design. Sites and farmers a...

Soil acidity poses a significant challenge to agricultural production in Ethiopia, with over forty-three percent of farmland affected, leading to low crop yields. Agricultural lime is widely recognized as an effective solution for addressing soil acidity. This study aims to evaluate the perception of smallholder farmers and factors influencing the...

Understanding seed degeneration in potato farming systems requires updated and pertinent information across different cropping systems and circumstances to find ways to deal with the problem. As a vegetatively propagated crop, potato is susceptible to pathogens and pest accumulation in seed tubers over successive cycles of vegetative propagation es...

In Ethiopia, the adoption of improved forage technology is low despite the fact that improved technology adoption can play a pivotal role in boosting livestock production and productivity in general and the dairy sub-sector in particular , thereby contributing to poverty reduction and food and nutrition security. This low adoption of improved forag...

Maize is Ethiopia's most important crop in terms of production, and it contributes significantly to the country's economic and social development. The study was conducted in Wonchi, Ejere, and Kersa Malima districts of South West Shewa and West Shewa zone of Oromia region, Ethiopia, to evaluate and identify adaptable improved maize varieties and fa...

The study was conducted in three dairy potential areas of Ginchi, Wonchi, and Debrelibanose districts of Oromia region Ethiopia, to demonstrate promising elephant grass materials to smallholder dairy farmers. As a part of the methodology, a participatory extension approach is employed in this particular study to select a demonstration site. A total...

Adoption of improved potato technology is essential for intensifying its productivity thereby improve the income of smallholder farmers in Ethiopia. Adoption of improved Potato also plays a great role for food security and improving the daily livelihood of farmers as well. However, there are few area-specific studies on its technology adoption to e...

Adoption of improved forage technologies remains to be one of a promising strategy to boost dairy productivity and enhance household income in many developing countries. However, there are limited rigorous impact evaluation studies on the contributions of such technologies on smallholder dairy productivity and household welfare. is paper examined t...

AB STRACT This activity was conducted from 2015-2017 during off season with the objective of demonstrating improved vegetable crops with production small scale drip irrigation by using participatory approach to women farmers which was conducted in Robi Gebeya Welemera District in Finfine surrounding special zone of oromiya regional state in Ethiopi...

The main objective of the study was to see the level of response of ten Napier grass accessions for their agronomic traits under acidic soil conditions of Nejo, Ethiopia. The study was conducted in randomized complete block design with three replications. Data on major traits such as plant survival rate, tillering performance, plant height, forage...

Background: Napier grass is a pioneer perennial forage crop and performs well in diverse environments. It produces a high biomass yield and could be also categorized as high-quality forage, which is highly palatable when young and leafy. Objective: To register and release high yielding, stable, and disease tolerant Napier grass varieties. Materials...

Background: Ethiopia has the highest livestock population in Africa. However, the productivity of livestock and the role it plays in the economy of the country is very low. This is mainly because of the inadequate availability of quality feed. Enhancing the production of alfalfa could contribute to overcome the shortage of feed in the country and e...

Five vetch species were evaluated for basic quantitative and qualitative traits at Holetta and Ginchi in the central highlands of Ethiopia during the main cropping season. The experiment was conducted using a randomized complete block design with three replications at each location. The result revealed that a species of vetch respond differently (P...

Though Ethiopia is one of the sub-Saharan African countries owning huge livestock population, productivity is one of the lowest in Africa. Among the various constraints to livestock production, problems related to feed shortage due to unavailability of planting materials are the most remarkable ones. As an alternate option, Holetta Agricultural Res...

The study was conducted to determine the optimum seeding rate for oats/vetch mixtures on vertisols and to evaluate the effect of waterlogging problem on productivity of oats/vetch mixtures during the main cropping seasons of 2012 and 2013 in the central highlands of Ethiopia. The experiment was conducted on a split-split plot design with three drai...

The main objective of this study was to investigate the major determinate factors of improved highland forages types in the study area and data were collected through survey by developing structured questionnaires for the total sampled households including household heads, members, key informants and subject matter specialists. The data were analys...

The study was conducted to evaluate the response of vicia species to different drainage methods on vertisol in the central highland areas of Ethiopia. The experiment was conducted on a split plot design using three drainage methods (CB, RF and FB) as main plot and five vicia species (V. sativa, V. villosa, V. dasycarpa " Lana " , V. dasycarpa " Nam...

Five alfalfa genotypes were evaluated for herbage yield potential and nutritional quality under supplemental irrigation condition at Holetta Agricultural Research Center during 2010-2014. The experiment was conducted in randomized complete block design with four replications. Diammonium phosphate (DAP) fertilizer at the rate of 100 kg/ha was unifor...
