Abstract: Calves are the foundation of the future dairy herd which signifies the importance of their proper rearing practices and needs to be performed at the herd and individual animal. This study was therefore conducted to assess calf husbandry practices in the urban dairy production system and to evaluate the effect of milk replacers on crossbred calf’s performance. The assessment was conducted in Dire Dawa city which was purposively selected based on its potential for dairy production....
Abstract: Nitrogen fertilizer is a major input required for cereal crop production in Ethiopia and its efficient use is important for the economic sustainability of cropping systems. Furthermore, the dynamic nature of N and its susceptibility for loss from soil-plant systems creates a unique and challenging environment for its efficient management especially on Vertisols. Developing suitable nitrogen fertilizer management practices is important strategy to improve productivity, quality and n...
Abstract: A study was conducted to evaluate the effect of dietary inclusion of mango seed kernel on growth performances (feed intake, body weight gain), feed conversion ratio, carcass characteristics, mortality percentages and partial budget analysis of broiler chicks at various levels of Mango Seed Kernel (MSK) as energy supplement at Haramaya University poultry farm.168 broiler chicks with average body weight 45.17±1.08g/b/d (mean ±SD) were randomly distributed to four treatments each wi...
Abstract: Faba bean (Vicia faba L.) is an important legume grown in the highlands of Ethiopia. However, the yield of the crop is limited by a number of edaphic constraints out of which low soil fertility, low pH and reduced N2 fixation due to various biological and environmental factors are the major problem. Therefore, a field experiment was conducted at Bore Agricultural Research Center under rain-fed condition during the 2015 main cropping season to evaluate effects of Rhizobium inoculati...
Abstract: The study was conducted to investigate the effect of mixtures of Ruta Graveolen (Ruta chalepensis L.), coriander (Coriandrum sativum L.), and basil (Ocimum basilicum) seed extracts in drinking water on productive performance, some blood profiles, egg quality, egg chemical composition, and economic benefit of white leghorn at Haramaya University poultry farm for 8 weeks. One hundred eighty White Leghorns (WL) layer at twenty- six weeks of age were randomly distributed to four treatm...
Abstract: The present investigation was conducted to determine the impact of the dietary addition of garlic and ginger as natural feed additives on feed intake, productive performance, carcass characteristics, hematology and serum biochemistry, economic efficiency, and mortality of broilers. A total of one hundred and ninety-two day old, unsexed (cobb-500) broiler were randomly divided into four experimental groups with three replication per treatment which consisted 16 birds. The birds were...
Abstract: Coffee plantation with shade trees is important to improve soil health, increase coffee production, sustain and restore agroecology and nature based agroforestry practices. The study was conducted on farmers’ fields in Golelcha District of East Arsi Zone, Ethiopia. The study was intended to evaluate the influence of coffee shade trees on growth performance, yield and quality of coffee (Coffea arabica L.), to characterize selected soil physicochemical ix properties under the canop...
Abstract: The climate change, water shortage and increasing evapotranspiration highlights the need to introduce water saving technologies for agricultural sustainability and crop production with a minimum input of water, mainly in semi-arid region. This experiment was conducted at Werer, Middle Awash Valley during the dry season of 2017/2018 to investigate the effects of mulching materials and furrow irrigation techniques on maize yield and water productivity under semiarid conditions. Split...
Abstract: The study was conducted at Bako Agricultural Research Center with the aim to evaluate the effects of Elephant grass ensiled with different proportion of Dolichos lablab on intake, digestibility, body weight gain and carcass parameters. Elephant grass was harvested after eight weeks of regrowth during rainy season and Dolichos lablab harvested at 50% blooming stage and both forages were chopped and weighed separately, mixed, added with 3% molasses and ensiled in pit. A total of twen...
Abstract: Soybean [Glycine max (L) Merrill] is among the most important legume crops produced in western Ethiopia. However, declining soil fertility as well as poor soil fertility management practices has limited its yields. A field experiment was conducted in Bako Agricultural Research center during 2018 main cropping season to investigate the effect of NPS rates on yield and yield components of soybean varieties and to identify economically feasible rates of blended NPS rate that increase ...
Abstract: Maize is the major food crop in western Ethiopia and is produced in a number of agro- ecologies. However, its productivity is constrained by low rates and inappropriate timing of N fertilizer applications. Therefore, a field experiment was conducted during the 2018 main cropping season in Nedjo district of western Ethiopia on a farmer’s field. The objectives of the study were to determine the effects of time and rate of nitrogen fertilizer application on growth, yield components ...
Abstract: Common bean is one of the most important food and export pulse crop in Ethiopia. However, its yield is limited by a number of constraints, which include poor agronomic practices such as low soil fertility management, inappropriate plant spacing, low and erratic rainfall and diseases. Hence, a field experiment was conducted at Yabelo during the 2018-2019 main cropping seasons to assess effect of rates of NPS fertilizer and inter row spacing on growth, yield components and yield of c...
Abstract: Use of appropriate verities and balanced fertilizer recommendation are important agronomic practices used to increase the productivity and quality of bread wheat. Hence, field experiment was carried out to assess the effect of NPS fertilizer rates on yield related traits, yield and grain protein of bread wheat varieties and to determine economically feasible NPS fertilizer rate for bread wheat production. The treatments consisted of five levels of NPS (0, 50, 100, 150 and 200 kg ha...
Abstract: Hot pepper is an important spice and vegetable crop in Assosa, western Ethiopia, however, its production is low due to several constraints of which low accessibility of improved varieties and poor cultural practices including soil fertility management. This research was conducted to asses the effect of blended NPS fertilizer on yield related and, green pod yield of hot pepper varieties and estimate cost-benefit of blended NPS fertilizer rates for hot pepper production. The research...
