Traditional methods of grading potato tubers require high labor-hour, cause fatigue to workers and has low output. Hence, engine driven machine capable of grading potato tubers into different size classes was evaluated. The grader prototype consisted of feeding table, grading cylinder and catchment tray. Grading capacity, grading system efficiency,...

Physic nut or Ayderkie in Amharic and Gullo in Oromiffa is a bush or small tree adapted in the drier and warmer areas of Ethiopia. It endures moisture stress by dropping its leaves during dry period and flourishes when the rain comes. The plant has received enormous attention of the government as raw material for biodiesel industry. Hence a serious of...

Although soil and agronomy data collection in Ethiopia has begun over 60 years ago, the data are hardly accessible as they are scattered across different organizations, mostly held in the hands of individuals (Ashenafi et al.,2020; Tamene et al.,2022), which makes them vulnerable to permanent loss. Cognizant of the problem, the Coalition of the Willing...

The study was designed to assess the performance of an improved and recently released tef variety called Kora. Districts selected for the study were Ada, Minjar-Shenkora and Moretna-Jirru. Primary data were collected using a set of validated interview schedule and testing the tef variety on field plots of ten lead farmers who were randomly selected from...

Crop production is the main source of food, and drought is among the most important crop production constraints in the world, particularly in sub-Saharan Africa. The use of improved cultivars can at least partly ameliorate the calamities of drought stress, and considerable investments and efforts have been made worldwide to develop drought tolerant crop...

Despite the importance of potato the late blight disease, caused by the oomycete Phytophthora infestans is most destructive disease for potato production. The study was conducted to identify virulent races and spatial distribution of Phytophthora infestans populations in major potato growing areas of northwestern Ethiopia in 2018. Seventy-four isolates...

Conservation tillage as an approach to reduce surface runoff and soil degradation and reduced tillage systems may offer a compromise solution. The objective of the study is to test different conservation tillage techniques and evaluate the impacts of the system on conserving water, labor requirement for pre and post planting, soil physicochemical...

Several constraints affect the performances of the farming system in Chencha suggesting the necessity of adjustments in the farm components. Therefore, an exploration was made to simultaneously optimize operating profit, labour and soil organic matter balances. Data from twelve farms and secondary data on improved technologies were used as bases for the...

Ethiopia experiences a very high soil loss of 40–130 t ha-1year-1 from croplands that costs the country about 1.0-1.5 million tons loss of grain production per year. Founded on its three interlinked principles, Conservation Agriculture (CA) is widely documented to reduce soil loss, improve soil quality and contribute to sustainable agricultural...

Laboratory experiment was conducted to determine the effect of mixing lentil grain with tef grain on the occurrence of Adzuki bean beetle (ABB), Callosobruchus chinensis and its natural enemy in stored lentil. Brown-seed tef grain was mixed with lentil (cu. Derso) grain on replacement basis at the rate of 0% (full lentil), 5%, 10%, 15%, 20%, 25%, and 30%...

Pathogenecity of entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae isolates of Ethiopian origin on eggs and adults of the two spotted spider mites, Tetranychus urticae, effect of temperature on virulence, as well as potentials of isolates in the greenhouse condition was assessed during October 2008 to May 2009 at Plant protection...

Performance evaluation of three single axle tractors namely Dongfeng15 hp and 12 hp Chinese made walking tractors and Vari6.5 hp Czech Republic made, were conducted at the Melkassa Agricultural Research Center (MARC). Drawbar and field performance data were recorded and analyzed. The experimental plots were laid side by side in a randomized complete block...

Data collected from field trial conducted to evaluate the response of soybean to rhizobia inoculation

An experiment was carried out at Debre-Zeit Agricultural Research Center to evaluate the performance of yearling Arsi-Bale lambs fed desho grass hay as a basal diet ad-libitum with and without supplementing concentrate mixture. Growth performance of the lambs was evaluated using desho grass hay ad libtum alone (T1) and supplemented with different...

To determine critical value of phosphorous fertilizer for wheat

Chickpea (Cicer arietinum L.) is grown in a wide range of environments and cropping systems and its maturity ranges from 80 to 180 days.. Time-saving breeding is key to responding to the dynamics of demands and environmental changes. The study employed Single Seed Descent (SSD) technique in advancing the generation, supported by an independent observation...

Field surveys were conducted in 2016 and 2017 belg season to generate baseline information on the type of pests prevailing in Belg and irrigated tef. The survey was conducted in five zones. Weeds were sampled in four 50 cm x 50 cm quadrats and the number of individual weed plants were counted and identified to species level in situ. Insect pests and...

Any particular soil results from the integrated action of soil-forming factors that occur in different kinds and degrees of expression that can be combined in many different ways; so that each combination produces a different soil with its unique properties resulting in the existence of thousands of different soils on earth. Soil genesis brings order to...

This paper analyzes the synergies/tradeoffs involved in the adoption of improved varieties of multiple crops in the mixed crop-livestock production systems of the highlands of Ethiopia A multivariate probit (MVP) model involving a system of four equations for the adoption decision of improved varieties of barley, potatoes, wheat and faba beans was...
