Abstract: Maize productivity under irrigation is affected by several factors including climate, soil and water management, quality of water and soil, and levels of irrigation and fertilizer application. This study consisted of four objectives to (1) analyze rainfall and temperature variability and change, (2) assess farmers' preferences for soil and water management practices, (3) assess the quality of water and soil, and (4) determine the effects of fertilizer and irrigation levels on maize...

Abstract: Climate variability affects crop productivity at both global and local scales, and adaptation of agricultural practices against this variability helps to translate perception of the farmers to decision-making process. This study was initiated to analyze climate variability, examine its effect on maize productivity, and assess perception and adaptation strategies of smallholder farmers to climate variability in West Badawacho District. Climate and crop data from 2000-2019 were colle...
Abstract: Teff is one of the dominant crops and its productivity is low in the study area. This means that it is possible to obtained additional output from existing inputs used, if resource are properly used and efficiently allocated. The aim of this study was to determine the level of technical efficiency of smallholder teff producers and identify factors affecting technical efficiency of smallholder farmers in teff production of Jamma district, South Wollo Zone, Ethiopia. A three-stage sa...
Abstract: Appropriate planting pattern and suitable variety of mungbean are important agronomic practices to increase the productivity of mungbean and sugarcane. Hence, a field experiment was conducted from June to August 2018 at Metahara Sugar Estate under irrigation to evaluate the performance of mungbean varieties intercropped in different planting patterns with sugarcane varieties; and to assess the effect of intercropped mungbean varieties on early growth and development of the associat...
Abstract: Realizing the importance of developing appropriate cultural practices for maize in Jijjiga area, a study was conducted for one season in 2016 with the objectives to (1) assessing the effect of intra-row spacing and in-situ moisture conservation methods on yield components and yield of maize; and (2) estimate the economically feasible intra-row spacing and in-situ moisture conservation methods for higher productivity of maize. Three intra-row spacing (20, 25 and 30 cm) and four in-s...
Abstract: Bread wheat is a major cereal crop in Ethiopia and in the study area, but its yield is limited due to minimum use of improved varieties, diseases, weeds, low soil fertility and lack of location specific fertilizer recommendation. Therefore, a field experiment was conducted during the 2016 main cropping season at Bore Agricultural Research Center to evaluate the effect of blended NPS and N fertilizer rates on yield components, yield and grain protein content; and to determine econom...
Abstract: A study was carried out at Haramaya University ‘Rare’ site to Evaluate the agronomic performance, forage yields, and chemical composition of three Cultivars of Brachiaria (Xaraes, Piata, and Basilisks) at three harvesting stages (60, 90 and 120 days). The experiment was conducted by 3*3 factorial arrangements in a randomized complete block design (RCBD) with three replications. The plot size was 4 m * 3 m (12 m2 ) with a total land area of 44 m * 15 m (660 m2 ). Data were analy...
Abstract: This study set out to assess factors affecting adoption of improved agronomic practices and its effect on income and nutrition of groundnut producing farmers in Babile district. The study focused particularly on identifying improved agronomic practices used by groundnut farmers, identifying factors affecting adoption of improved agronomic practices, and investigating the effect of adoption of improved agronomic practices on income and nutrition of farm households. The study employe...
Abstract: This experiment was conducted with the objectives of determining the effect of harvesting stages on agronomic traits, herbage yield, chemical composition, In vitro dry matter digestibility (IVDMD) and In vitro organic matter digestibility (IVOMD) and In sacco rumen dry matter degradability of Sudan grass mixed with, Lablab in Faafan zone, Ethiopia. The study was executed using 3 x 3 factorial arrangements in randomized complete block design (RCBD) with three replications in plot si...
Abstract: This study was conducted at Haramaya University ‘Rare’ research site to evaluate morphological characteristics, dry matter yield, and chemical composition of Desho grass (Pennisetum glaucifolium) as affected by vetch intercropping and harvesting stage. The experiment was arranged in a 3*3 factorial using a Randomized complete block design (RCBD). The treatments comprise sole Vetch, Desho*Vetch intercrop, and sole Desho grass and three harvesting stages (60, 90, and 120 days aft...
Abstract: Ripening management is one of the core practices in sugarcane production to boost the sucrose content. Conventionally, in Ethiopian Sugar Industry, withholding irrigation through drying off the cane prior to harvesting is commonly conducted to facilitate the improvement of sucrose content. However, this method of ripening lacks accurate control of crop water supply and there is risk related to reduction in sugarcane and sucrose yield resulting from excessive withholding of water. C...
Abstract: Maize-legume cropping systems are practiced under conventional practice (CP) which has resulted in soil degradation and frequent crop failure, which may be slowed or reversed with conservation agriculture (CA). Traditional plant tissue sampling and analysis is time taken and destructive method; whereas optical sensor techniques in particular, normalized difference vegetative index (NDVI) are an instantaneous, non-destructive, and quantitative assessment. CA can improvesoil health a...
Abstract: Bread wheat is one of the most important cereal crops produced in Mao-komo (Benishangul Gumuz). However, appropriate management practice that combines integrated application of organic and inorganic fertilizer is lacking in Mao-komo. Thus, field experiment was conducted from August to December 2020 to assess the effects of integrated application of vermicompost and NPS on yield and yield components of bread wheat in Mao-komo. Factorial combinations of four levels of vermicompost ( ...
Abstract: Maize is one of an important cereal crop in Ethiopia due to its uses as sources of food and income generation. Its productivity is constrained by drought, blanket fertilizer recommendation and non-optimum plant population. The experiment arranged in a factorial combination in a randomized complete block design (RCBD) by replicating three times. It contain Four Potassium Chloride (KCl)(0 kghe-1, 20 kghe-1, 40 kghe-1 and 60kghe-1 )levels and four level of inter row spacing (IRS)55 cm...
