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. A total of 192 Cobb 500 day-old broiler chicks with initial body weight of 36.23±0.25 (Mean±SD) gram were randomly 16 chicks per replicate distributed into 12 pens, representing 4 treatment diets each replicated three times. The experiment lasted for 45 days...
Abstract: Common bean (Phaseolus vulgaris L.) is one of the most important cash crops and source of protein for farmers in many lowlands and mid-altitude area of Ethiopia. However, appropriate management practice that combines high yielding varieties with balanced fertilizers are lacking in the study area under irrigation. Thus, a field experiment was conducted to assess the effects of NPS fertilizer rates on growth, yield components and yield of common bean varieties, and to evaluate cost-b...
Abstract: Low available phosphorus, total nitrogen, lack of adequate information on the use of Rhizobium inoculants and nitrogen-phosphorus-sulphure blended fertlizer are the major yield limiting factors for common bean production in the study area. Thus, the experiment was conducted at Bolosso Bombe District in 2016 (July-October), to evaluate the effect of Blended NPS fertilizer rates and Rhizobium inoculation on the yield components and yield of common bean varieties; and to identify econ...
Abstract: Haramaya University main campus, Eastern Ethiopia, with the objectives of evaluating the effect of methods of Rhizobium inoculation and phosphorus (P) rates on nodulation, yield components and yield of faba bean and to identify economically beneficial treatment (s) for higher yield of faba bean. Factorial combinations of five P levels (0, 23, 46, 69, 92 kg P2O5 ha-1) and four levels of Rhizobium inoculation methods (uninoculated, seed inoculated, soil inoculated, seed + soil inocul...
Abstract: Low soil fertility and poor crop management practices including use of inappropriate seeds rates are among the major constraints limiting the productivity of wheat in Ethiopia in general and in the study area in particular. Thus, field experiment was conducted to assess the effect of rates of seed and blended fertilizer (NPS) on growth, yield components and yield of bread wheat and to identify economicaly feasible rates of seed and blended NPS in the study area. Factorial combinati...
Abstract: Four interrelated studies were conducted to assess milk handling practices, microbiological quality and safety of raw cow milk across the milk supply chain in eastern Ethiopia. The first study evaluated hygienic cow milk production practices of producers, while the second study assessed milk postharvest handling practices of producers, collectors/transporters, vendors and consumers across the milk supply chain in the study area. Both studies employed cross sectional survey. The stu...
Abstract: Mung bean has become an important cash and food crop in dry land areas of Ethiopia. However, there are no sufficient research information on the nitrogen (N) and phosphorus (P) fertilizers rates for the crop in the study area. Thus, field experiment was conducted to assess the effect of N and P fertilizer rates on the growth, yield components and yield; and to identify economically feasible rates of N and P fertilizers. The experiment was conducted at Nura -Era, Upper Awash under i...
Abstract: The experiment was conducted at Yabello Pastoral and Dry land Agriculture Research Center with the objectives to evaluate the effect of supplementation of browse species mixed with wheat bran on feed intakes, digestibility, growth performance and carcass characteristics of Borena goats fed a basal diet of native pasture hay, and to identify the economic feasibility. The experiment was conducted using Twenty five (25) intact male yearling Borena goats with an average live weight of ...
Abstract: On-farm study was conducted to evaluate and demonstrate the effects of urea treated straw and urea molasses block on milk yield, milk composition, feed intake and body weight gain of cross-bred lactating dairy cows in urban and peri-urban dairy production system of Lume District. Three treatments were considered: T1: urea treated straw + concentrate, T2: urea molasses block + untreated teff straw + concentrate and T3: untreated straw + concentrate. Pre-visit and survey was made and...
Abstract: Black cumin is a seed spice cultivated in Ethiopia for a long period of time. It is also cultivated in Goro district of Bale Zone by small land holder farmers. However, expected benefit of this crop is not being obtained by farmers since they are using in-appropriate agronomic practices such as inappropriate seed rate without any fertilizer application. Therefore, a field experiment was conducted in Goro district, south Eastern Ethiopia. The objective of the experiment was to deter...
Abstract: The study was conducted in Metekel Zone, Northwest Ethiopia to characterize indigenous chicken production system and to analyze egg quality parameters. The data was collected through structured questionnaire and focused group discussion, egg quality analysis were done in poultry farm laboratory of Haramaya University. The research was conducted in three districts of Metekel Zone. Four kebeles from each district and two kebeles from each agro-ecology of (highland and lowland) were s...
Abstract: The study was conducted to evaluate the effect of soybean or groundnut straw replacement for hay on feed intake, nutrient utilization, live weight change and carcass characteristics, of Gumuz sheep at Pawe Agricultural Research Centre. Thirty yearling male intact Gumuz sheep with initial body weight of 18.91 ± 2.6 kg (mean ± SD) were used in the experiment. The study consists of 90 days feeding trial and 7 days of digestibility trial after acclimatization of 15 and 3 days for the...
Abstract: A study was conducted to assess the effect of replacing maize with raw or roasted barley, as an energy source in concentrate based diets, on feed intake, weight gain and carcass characteristics of broiler chickens for a period of 56 days. Based on the ingredients chemical analysis results, seven treatment rations were formulated in mash form. In the control diet (T1), maize was served as the main energy source without barley grain inclusion and six treatment rations in which maize ...
Abstract: Livestock production and tanneries have high potential in Ethiopia, even though there are a critical shortage of quality raw hides and skins at national level. In the study districts there is high livestock population potential for hide and skin production but different types of defects were observed and hampered the effective and efficient utilization of these resources. Therefore, cross- sectional study was conducted in Bako Tibe and Ilu Gelan districts, West Showa zone, Oromia R...
