Abstract: Ensuring food security is one of the greatest challenges facing the world scientific community to feed the ever-increasing human population in a sustainable way. The low soil fertility is one of the major constraints which limit crop production in sub-Saharan African countries including Ethiopia. The major soil related constraints in the study area are strongly alkaline condition, high soil pH, low soil OM, low available P and medium total N. Therefore, a field experiment was condu...
Abstract: The study was conducted in three districts of Borana Zone, with the objective to determining the impacts of climatic factors and grazing on vegetation structure, herbaceous biomass yield and soil nutrients of Borana rangelands under traditional enclosure and continuous grazing rangeland types during end of growing season. Within both rangeland types of each districts 20 m x 20 m plots were placed at 200 m distances intervals with three replication used to collect woody vegetation a...
Abstract: The study was conducted in Elida'ar district, Afar National Regional State, to assess the overall camel production practice (husbandry practices, production, product utilization, product handling practice, marketing and reproduction) and constraints that influence camel production in the study area. The study was undertaken in seven selected pastoral area of Elida'ar district. According to the formula a total of 196 households (HH) were selected from the study areas. The household ...
Abstract: This study was conducted to evaluate the forage production, chemical composition, in vitro dry matter digestibility and rumen degradability potentials of improved Napier grass cultivars as well as their preference as livestock feed under farmer’s conditions in West Hararghe Zone of Oromia region, Ethiopia. Four improved Napier grass cultivars (ILRI cultivar number: 16801, 16800, 16798, and 16840) and local check were planted in a Randomized Complete Block Design (RCBD) with six r...
Abstract: A field experiment was conducted during the 2016 cropping season on Weilu Mojo FTC in Hidebu Abote District, central Ethiopia. The objectives of the study were to determine the effects of N and seeding rates on yield and yield components of tef, to identify the most appropriate seeding and N rates and to determine the economic benefits of each treatment. A 4 x 4 factorial combinations of nitrogen (42, 65, 88 and 111 kg ha-1) and seeding rates (2.5, 5, 7.5 and 25, (farmers’ practi...
Abstract: The huge and diverse livestock population, favorable climate for improved high-yielding cattle breeds, increasing demand for dairy products in urban and peri-urban areas and long-standing culture of dairy products consumption make Ethiopia to hold a substantial potential for dairy development. The study was conducted in Gondar district, North Gondar Zone of Amhara Regional State with the objectives: To assess milk production performance and production constraints, milking and proce...
Abstract: Common bean is becoming an important pulse crop in Ethiopia due to its use as sources of food security and generated income. However, crop management practice that combine high yielding varieties with inter row spacing are lacking at Nejo. Thus, a field experiment was conducted to assess effect of inter row spacing and varieties on yield components and yield of common bean.It was conducted during 2018 cropping season at Nejo, western Ethiopia. Treatments consisted of factorial comb...
Abstract: Soybean is an important crop in the tropical, hot sub-moist agro-ecological zone of western Ethiopia. However, the yield of the crop is limited due to lack of appropriate plant density for the varieties. Therefore, the experiment was conducted to determine the effect of inter and intra row spacing on growth, yield components and yield of soybean varieties during 2016 cropping season in Dale Sedi District, western Ethiopia. Four inter row spacing (30, 40, 50 and 60 cm) and two intra...
Abstract: Determination of optimum plant population and the use of improved varieties in combination with appropriate agronomic practices are important components of maize production package for maximizing productivity. In connection with this, information is lacking on optimum plant population under supplementary irrigation condition during the off-season in Guliso District. Therefore this study was conducted during December 2017 to May 2018 under supplementary irrigation at Gulliso distric...
Abstract: The aim of the study was to evaluate productive and reproductive performance of indigenous and their crossbred dairy cows owned by farmers and factors affecting their performance in Agarfa district of Bale Zone, Oromia Regional state. A total of 120 household dairy cows’ owners were selected from four kebeles and interviewed with pre-tested structured questionnaire to obtain information related to husbandry practices, animal productivity and feed resource. Out of this, 40 Dairy f...
Abstract: The study was aimed to assess dairy production practice, milk handling and marketing practices and to evaluate the quality and safety of raw milk produced and marketing in in urban and peri urban areas of Girar Jarso district. A total of 150 sample respondents (120 from dairy producers and 30 from milk collectors) were interviewed using a semi structured questionnaire. The survey work includes: dairy cattle management, milk production performance, house type and cleaning practices,...
Abstract: Sweet potato is one the most important root crops produced in western Ethiopia. However, the yield is far below its genetic potential. Lack of recommendation on appropriate rates of fertilizers is one of the problems limiting yield. A study was conducted to determine the effect of application of farm yard manure and inorganic phosphorus on tuberous root yield and yield related traits of sweet potato at Assosa from July to December 2016. The treatment consisted of four levels of far...
Abstract: An experiment was conducted to evaluate the effects of supplementing Moringa stenopetala leaf mea l(MSLM) on feed intake, growth performance and carcass characteristics of cobb 500 Chicken at Haramaya university poultry farm.
