Abstract: Bread wheat is one of the major crops in the study area cultivated both for home consumption and market purposes. However, its productivity is mainly constrained by poor soil fertility and lack of site specific fertilizer (NPSB) recommendation. Therefore, field experiment was carried out to assess the effect of blended NPSB fertilizer rates on yield, and yield related traits on selected bread wheat cultivars during the 2018/2019 cropping season on farmer training center (FTC) in Ke...
Abstract: Potato is an important food and cash crop in eastern Ethiopia including Oda Bultum District of West Hararghe Zone. However, there is no information on the role of blended NPSB fertilizer required to produce tuber yield and tuber quality traits of potato varieties in Oda Bultum District. A field experiment was conducted in Oda Bultum District, under rainfed during 2018 cropping season, with the objectives of assessing the effects of blended NPSB fertilizer rates on yield-related tra...
Abstract: Nitrogen and phosphorus deficiency are the most important production constraint of maize next to moisture deficiency. Therefore, a field experiment was conducted at Haramaya University main campus research station (Rare), eastern Ethiopia, using a maize hybrid xv variety (BH 661) as a test crop in the 2015 cropping season. The objectives of the study were to investigate the effects of nitrogen and phosphorus fertilizer application on growth, yield components and yield of the maize ...
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: 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: 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: 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: 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: 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,...
