Abstract: Optimum plant spacing and number of seedlings per hill are important agronomic practices for the productivity of rice. Hence, field experiment was carried out to assess the effect of plant spacing and number of seedlings per hill on yield components and yield of transplanted rice under irrigation at Werer, Middle Awash. Factorial combinations of 2 inter-row spacing (20 cm and 30 cm), 3 intra-row spacing (10 cm, 15 cm and 20 cm) and 3 seedlings (2, 3 and 4) per hill were laid out in...
Abstract: Cabbage (Brassica oleracea L.) is a member of the cole crops, and it is an important fresh and processing vegetable crop in most of the countries of the world. However, yield of the crop is often constrained by low and imbalanced nutrient supply in the country at large and in Gudji Zone in particular. Therefore, this study was conducted at the Bore Agricultural Research Center (BoARC) during the period from July 1, 2014 to December 2, 2014 main cropping season to assess the effects...
Abstract: Poor soil fertility, lack of indigenous soil populations of rhizobia strains and lack of adequate information on the use of Rhizobium inoculants and phosphorus fertilizer are the major production constraints that limit the potential yield of faba bean. Thus, field experiment was conducted to assess the effect of Rhizobium inoculation and phosphorus fertilizer rates on yield components and yield of faba bean; and to estimate the economically feasible combination of inoculants and ph...
Abstract: A study was conducted at Haramaya University dairy farm to evaluate the feeding value of peanut meal (PM) with concentrate feeds on milk quality, milk yield, milk composition and its economic feasibility for Holstein Frisian cows. Changeover design was used in three periods each comprising 25 days plus the first seven days for adaptation and ten days for wash out residual effect between consecutive periods. Treatment diet was PM while soy bean meal (SBM) was used as control leveled...
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: A study was conducted to evaluate supplementation effect of graded levels of faba bean hull (FBH), maize grain (MG) and wheat bran (WB) mixture on feed intake, digestibility and growth performance of Bonga lamb fed a basal diet of natural pasture hay (NPH). Twenty yearling male lambs with an initial body weight of 21.55 kg ± 2.41 (Mean ± SD)” were blocked into five based on their initial body weight and animals within a block were randomly assigned to each treatment. Treatments...
Abstract: A study was conducted to evaluate the effect of substituting different levels of sweet potato tuber meal (SWPTM) for maize on egg production, fertility, hatchability and egg and chick quality of white leghorn chicken at Poultry Farm of Haramaya University. A total of one hundred ninety two (168 hens + 24 cocks) at age of 42 weeks with initial body weight of 997.95g±19.2 (mean ±SD) were randomly distributed into 12 pens each with 14 hens and 2 cocks. The experimental animals in a ...
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.
