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: 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: 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 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: Producing chickpea on Vertisol without fertilizer application leads to low yields because of low soil nutrient availability. Hence, a field experiment was conducted in 2017/2018 in Ada’a-Liban District of East Shoa Zone, Ethiopia, to assess the effect of rates of blended NPSZnB and DAP fertilizer on yield components and yield of chickpea varieties. Treatments consisting of four levels of blended NPSZnB fertilizer (0, 64.4, 129 and 193 kg ha-1) and four chickpea varieties (Natoli,...
Abstract: Onion (Allium cepa L.) is one of the major horticultural crops grown in Dembiya district, Ethiopia. However, due to lack of research recommendations on agronomic practices, growers are not using optimum irrigation level and NPSB blended fertilizer rate. The main objects of this study to check the effects of drip irrigation levels and NPSB blended fertilizer rate. The treatment consist of three irrigation levels (100%, 80% and 60% ETc) and five NPSB blended fertilizer rate (0, 50, 1...
Abstract: Rice is an important crop in Maitsebri area in Tigray region but the productivity of the crop constrained by lack of appropriate agronomic practices including seed rate and also lack of nitrogen fertilizer in the region. Thus, a field experiment was conducted in 2016 main cropping season in Tselemti District, Northwest Tigray Zone to assess the effect of seed and nitrogen fertilizer rates on major upland rice varieties; and to identify economically feasible seed and nitrogen fertil...
Abstract: Malt barley being an important cash crop of the study area, it was cultivated for both home consumption and market purposes. However, its productivity and grain quality is mainly constrained by low yielding vareity, lack of approprite time of N fertilizer application and seed rate recommendation in the study area.Thus, this study was carried out under farmer’s field at Bekoji district during 2018 main cropping season to assess the effect of varieties, time of nitrogen application...
Abstract: A total of sixteen barley (Hordeum vulgare L.) genotypes were evaluated for genetic variability and character associations at two different environments. The genotypes were grown in a simple lattice design. Data were collected on 16 morpho-agronomic characters. The analysis of variance at each location showed significant (P< 0.05) difference for all of the characters, except spikelets per spike gonder This indicated the existence of variability and hence the potential for selection...
Abstract: Scarcity of water is the most severe constraint for development of agriculture in arid and semi-arid areas. Under such conditions, the need to use the available water economically and efficiently is indisputable. The important strategy for increasing water productivity and improving water use efficiency in the area of water scarcity, was deficit irrigation. A field experiment was conducted at Mehoni Agricultural Research Center during off season aimed at investigating the effect of...
Abstract: Maize (Zea mays L) is an important food security crop widely grown in Hararghe Zones, eastern Ethiopia. However, the average yield of the crop is low due to several biotic and abiotic production constraints, among which low soil fertility and moisture stress are the major factors. As a result, three field experiments were conducted in the Haramaya District during the 2019/20 and 2020/21 main cropping seasons. The first objective was to investigate the response of two hybrid maize v...
Abstract: Hot pepper is an important spice and vegetable crop in Ethiopia, but its productivity is low due to poor agronomic practices including inappropriate nutrient supply and poor seedling management before transplanting. Therefore, a field experiment was conducted on the demonstration field at Agarfa Agricultural Technical Vocational and Education Training (ATVET) College in Bale Zone, south-eastern Ethiopia to evaluate the effects of nitrogen fertilizer and hardening seedlings on fruit...
Abstract: Maize production plays vital role for the producers of the study area in serving as staple food. However, its productivity is constrained by a number of factors out of which optimum spacing is among the most important production factors. The Objective of the experiment was to investigate the influence of inter and intra-row spacing on yield components and grain yield of maize in 2019 cropping season at Chinaksen, East Hararghe Zone, eastern Ethiopia. The experiment was arranged in ...
Abstract: A field experiment was conducted inBabile District during the main cropping season of 2019 to evaluate the effect of plant spacing (inter- and intra-row spacing) on yield and yield related traits of sorghum (Sorghum bicolor(L.)Moench].Four inter-row spacing (65 cm,75 cm,80 cm and 90cm) and four intra-row spacing (15, 20, 25 and 30 cm ) were evaluated as treatments using a randomized complete block design with three replications. Yield and yield related parameterswere collected and ...
