Sweetpotato plays an important role in ensuring food security and household income sources for local communities in Ethiopia. It is dominantly grown in southern parts of Ethiopia. However, its production and productivity over the last few years has declined due to the limited access of quality planting materials at the onset of the rainy season, disease, and severe pest infestation. Therefore, it was imperative to carry out this study to identify the main constraints related to the recent decline in sweet in Misrak Badawacho District. The survey result revealed that many varieties of sweetpotato were grown in the district; mainly, Awassa‐83, Ogan‐Sagan, and Wolaita‐local were the most preferred variety by producers. The main sweetpotato production and storage constraints in the study district are as follows: rodents, disease and insect pests, heat and drought, shortage of quality planting materials, and absence of best methods for long‐term storage. Ogan‐Sagan and Wolaita‐local were evaluated under different storage types (straw, soil, ash, sawdust, and sand storage). The combination of Awassa‐83 variety and sand storage was performed better in percentage of decay, weight loss, and weevil damage, whereas length and number of vine per storage roots were performed better in the separate treatment. Thus, Awassa‐83 variety and sand storage can be recommended for maintaining the storage roots during dry periods and access of quality vines at the onset of the rainy season. More importantly, sand storage provides an opportunity to maintain the quality of sweetpotato storage roots for a long period of time and producers can easily and timely access quality vines at the onset of rainy season.

不同存储类型下的甘薯生产实践，约束和品种评估

甘薯在确保埃塞俄比亚当地社区的粮食安全和家庭收入来源方面发挥着重要作用。它主要生长在埃塞俄比亚南部。然而，由于雨季开始时优质种植材料的获取有限，疾病和严重的虫害侵袭，近几年来其产量和生产率下降。因此，有必要进行这项研究，以确定与Misrak Badawacho地区最近甜味下降有关的主要制约因素。调查结果表明，该地区种植了许多品种的甘薯。主要是Awassa-83，Ogan-Sagan和Wolaita-local是生产者最喜欢的品种。研究区主要的甘薯生产和储存限制如下：啮齿动物，疾病和害虫，高温和干旱，缺乏优质种植材料以及缺乏最佳的长期存储方法。Ogan-Sagan和Wolaita-local在不同的存储类型（稻草，土壤，灰烬，锯末和沙子存储）下进行了评估。Awassa-83品种和沙贮的组合在腐烂，体重减轻和象鼻虫的损害百分比上表现更好，而在单独处理中，每贮藏根的藤蔓长度和数量则表现更好。因此，建议使用Awassa‐83葡萄品种和沙土储藏，以在干旱时期保持储藏根，并在雨季开始时获得优质藤蔓。更重要的是，沙贮提供了一个机会，可以长期保持甘薯贮藏根的质量，生产者可以在雨季开始时轻松，及时地获得优质藤蔓。
