Assessment of production potential and post-harvest losses of fruits and vegetables in northern region of Ethiopia

Abstract Background Horticultural crops are sources of vitamins, minerals and dietary fiber, but their cultivation is not widely practiced in developing countries, like Ethiopia due to small-scale farming systems and poor pre- and post-harvest handling techniques. In Ethiopia, particularly in northern region, the production of horticultural crops usually practiced in very few pocket areas, such as at river and lakesides. Thus, the production of fruits and vegetables is just at the beginning stage and getting momentum by governmental and non-governmental organizations. To assess the production potential and post-harvest losses of fruits and vegetables, a survey research was conducted in Tigray Regional State, northern Ethiopia. From the study area, Atsbiwenberta district was selected with its four purposely selected Kebeles (Kebelle is the lowest administrative division of Ethiopia next to districts in each administrative region) (Ruwafeleg, Felegewoni, Golgolnaele and Hayelom) in which 120 respondents (30 households from each Kebele) were participated. Data were collected from both primary and secondary data and analyzed using simple descriptive statistics like frequency, mean and percentage. Results From this survey research it was found that the region has the potential to produce both temperate and subtropical fruits and vegetable crops. However, their production potential was limited by different constraints starting from cultivation to consumption. Focus group discussion reveals that farmers obtained high production of potato and apple with average yield of 300–400 and 25–130 qt/ha, respectively. Conversely, post-harvest loss was significantly affected in the study area due to lack of awareness, market access, inadequate water supply and poor post-harvest handling practices. As a result, the loss of potato and other vegetable crops was ranged from 30 to 50 and 0.25 to 5 qt/ha, respectively. Conclusions Therefore, designing further research projects is recommended on production and post-harvest handling of fruits and vegetables. In addition, all stakeholders should be designed market linkage and involvement of female farmers in production of horticultural crops

Ethiopian Mustard (Brassica carinata A. Braun) as an Alternative Energy Source and Sustainable Crop

Energy and food source crop demand claims to be vulnerable to climate change impacts. The new and orphan crops, which in the past have received only limited research attention but are sustainable to environmental systems, are needed. In this review, we summarize the available literature about Ethiopian mustard as an alternative energy source and its sustainable economic importance as a new promising Brassicacea crop for new opportunities in the face of producing sustainable environment and energy development. Ethiopian mustard has many advantages and can be adopted to replace crops that are susceptible to adverse environmental conditions. Ethiopian mustard is becoming a new promising Brassicaceae crop with the current global energy demand increases. However, researchers have only focused on energy source production which has resulted in developing high erucic acid varieties. This results partly in limited studies on developing Ethiopian mustard edible oil varieties. The adoption and scaling-up of this promising crop as an oilseed crop in developing countries and Mediterranean conditions can sustain the impact of climate change with the demand for food and energy debate concepts. Indeed, further agronomic, quality and genomic studies on oilseed nutritional traits for efficient breeding and utilization are needed
