Abstract: Bread wheat is one of the major food security crops in Tigray Regional State, northern Ethiopia. However, moisture stress and low soil fertility limits the production of bread wheat in the region. As a result, three field experiments were conducted in Enderta district in the 2013 and 2014 main cropping seasons with four key objectives. 1. To assess the impact of different rates and timing of nitrogen fertilizer application on the yield, quality, and nitrogen use efficiency of bread...
Abstract: The study was conducted to phenotypically characterize and assess husbandry and breeding practices of Simada cattle population in three districts of North-Western Ethiopia. Data were collected through semi-structured questionnaire, focus group discussions, field observations and linear body measurements (LBM). A total of 180 households were randomly selected to fill the structured questionnaire and 360 cattle (60 male and 300 female) were sampled for morphological description and l...
Abstract: Evaluation of genotypes for the existence of variations and generation of genetic information is the key step in plant breeding to develop varieties for the targeted area of production. Twenty desi chickpea genotypes were tested in randomized complete block design with three replications. The objectives of the study were to estimate the extent of genotypic and phenotypic variability, estimate the genotypic and phenotypic associations among characters and to estimate the direct and ...
Abstract: The study was conducted in Deghabur district of Somali Regional State, with the objectives of generating base line information about the livestock husbandry practices, to identify the available feed resources. The study was undertaken in four purposely selected Peasant Associations (PAs) according to their road accessibility and potential for livestock population; total sample sizes of 120 household were used for the study. Semi structured questionnaires were held with pastoralists...
Abstract: This PhD dissertation is based on three studies. The first was a survey work aiming to describe and compare the current pig production practices in and around Bishoftu and Holeta towns, central Ethiopia. A total of 20 and 23 pig farms from Bishoftu and Holeta towns respectively were visited. The second study was aimed at establishing the effects of inclusion of sun dried bovine rumen content (SDRC) as ingredients in diets of pigs during post weaning growth phase for 90 days. A tota...
Abstract: Bread wheat is a major cereal crop in Ethiopia and in the study area, but its yield is limited due to minimum use of improved varieties, diseases, weeds, low soil fertility and lack of location specific fertilizer recommendation. Therefore, a field experiment was conducted during the 2016 main cropping season at Bore Agricultural Research Center to evaluate the effect of blended NPS and N fertilizer rates on yield components, yield and grain protein content; and to determine econom...
Abstract: The study was aimed at evaluating improved Horro, Koekoek, Kuroiler and Sasso-RIR chicken strains for productive and reproductive traits under semi-scavenging conditions and characterizing the poultry production system in Kolfe and Nifassilk districts of Addis Ababa administration. Random samplings were employed to select sample kebeles, households and respondents. For characterization of chicken production systems, a pre-tested questionnaire was administered to 121 households in s...
Abstract: Ethiopia is endowed with cattle population which plays vital role in enhancing smallholder income, food security of households and foreign earnings of the country. But, the productivity per animal is low. To solve the cattle productivity problem, crossbreeding through AI is one of the solutions under operation in Ethiopia. However, the adoption of AI is constrained and determined by several factors. This research was intended to assess the perception of farmers towards the AI techn...
Abstract: The study was conducted at Haramaya University goat farm using 24 intact Hararghe Highland sheep with a mean initial body weight of 16.02±2.5 (mean±SD) to investigate the effect of feeding dried Atella with concentrate mixture on feed intake, apparent digestibility, body weight change, feed conversion efficiency, carcass and meat quality evaluations as well as the economic feasibility of feeding regime of sheep fed a basal diet of grass hay. The experiment consisted of 90 days of...
Abstract: As elsewhere in the country, in Tigray Region, community-based seed production has a potential for improving farmers' access to quality seed of locally adapted and preferred varieties. Besides, Seed Producing Cooperatives (SPCs) are also fully engaged in formal seed production as contract out-growers to public enterprises that benefits members economically. Though the agro ecology of the study area is suitable for seed production, many of the smallholder farmers in Southern Zone of...
Abstract: A study was carried out at Haramaya University ‘Rare’ site to Evaluate the agronomic performance, forage yields, and chemical composition of three Cultivars of Brachiaria (Xaraes, Piata, and Basilisks) at three harvesting stages (60, 90 and 120 days). The experiment was conducted by 3*3 factorial arrangements in a randomized complete block design (RCBD) with three replications. The plot size was 4 m * 3 m (12 m2 ) with a total land area of 44 m * 15 m (660 m2 ). Data were analy...
Abstract: Dairy production is an integral part of rural livelihoods in Ethiopia in general and in Ada’a woreda in particular. Farming households in the study area produce milk for both generating income and own production. But lack of information related to dairy production and marketing is one of the major challenges for this smallholder farmers. Understanding the reasons behind such problem and dairy farmers’ current information accessibility is paramount importance. This study was con...
Abstract: Three interrelated studies were conducted. The first was a survey to assess farmers’ perception, production and utilization of improved forages (IF) under rural and peri-urban production systems of the selected districts of central highlands of Ethiopia. The other studies were conducted to evaluate the comparative nutritive value of vetch hay (VH), and 3 oil seed cakes (noug seed cake (NSC), cotton seed cake (CSC) and linseed cake (LSC), natural pasture hay (NPH) and a ration for...
Abstract: The shortage of arable land and shortage of livestock feed are major constraints in East Hararghe Zone. Thus, a field study was conducted to evaluate early maturing sorghum varieties and cowpea varieties intercropping for both food and feed production at Fedis Agricultural Research Center, eastern Ethiopia in 2018 cropping season. With a total of 11 treatments; Two cowpea varieties (9333 and 9334) and three varieties of early maturing sorghum (Teshale, Birhan and Melkam) and their ...
