Abstract

In Ethiopia, improved hive technology dissemination was started before five-decades. However, the adoption of improved beekeeping technology is still very low. This study was conducted with the main objectives to evaluating improved beekeeping adoption level and honey yields of different hives and identification of major honey bee plants and flora calendar in the Gedeo zone, South Ethiopia. Three districts were selected purposively based on beekeeping potential and the number of improved hives own by beekeepers. The data was collected from 180 respondents using cross-sectional survey. The data was analyzed by using descriptive statistics such as mean, frequency and percentage and ANOVA. The result shown that the compositions of disseminated hives in the entire sampled respondents were 286, 476, 121 and 1494 Zander hive, Kenyan top bar hive (KTBH), Mud/Ethio-Ribrab hive (ERH) and Traditional hives respectively. Traditional beekeeping was the dominant system with 63% and intermediate followed by 25%, while modern beekeeping was only 12%. Based on overall mean honey yield, there was no significant difference (P = 0.244) between Zander and KTBH. However, the average honey yield of these improved hives were significantly (P<0.05) higher than Mud/ERH and Traditional hives. Gedeo zone had rich floral resource and diverse floral calendar. Hygenia abyssinica, Bidens ghedoensis, Erythrinia abyssinica, Eucalyptus species, Cordia africana, Coffee arabica, Vernonia species, Susbania susban and Persea americana were major honey bee flora in Gedeo zone. February-March was major honey harvesting season while May-July and October-December respectively were minor honey harvesting periods. Nevertheless, the majority of beekeepers have been practicing honey harvesting once a year from all hives due to lack of awareness and practical skills. Therefore, we recommend that the local government should focus on educating beekeepers to enable them utilizing exhaustively the opportunities of multi-floral season and improved hive technology to maximize honey yield in the area.

摘要

在埃塞俄比亚,改良蜂箱技术的传播始于五十年前。然而,改良养蜂技术的采用率仍然很低。本研究的主要目的是评估不同蜂箱的改良养蜂技术采用水平和蜂蜜产量,并确定埃塞俄比亚南部盖多地区的主要蜜源植物和花卉日历。根据养蜂潜力和养蜂人拥有的改良蜂箱数量,有目的地选择了三个区。使用横断面调查从 180 名受访者那里收集数据。使用描述性统计(如平均值、频率和百分比以及方差分析)对数据进行分析。结果表明,在整个抽样受访者中,传播的蜂箱组成分别为 286、476、121 和 1494 个赞德蜂箱、肯尼亚顶杆蜂箱(KTBH)、泥/埃塞俄比亚-里布拉布蜂箱(ERH)和传统蜂箱。传统养蜂是主要系统,占 63%,其次是中间系统占 25%,而现代养蜂仅占 12%。根据总体平均蜂蜜产量,赞德蜂箱和 KTBH 之间没有显著差异(P = 0.244)。然而,这些改良蜂箱的平均蜂蜜产量明显高于泥/ERH 和传统蜂箱(P<0.05)。盖多地区拥有丰富的花卉资源和多样的花卉日历。Hygenia abyssinica、Bidens ghedoensis、Erythrinia abyssinica、桉树属、Cordia africana、咖啡阿拉伯、Vernonia 属、Susbania susban 和 Persea americana 是盖多地区的主要蜜源植物。2 月至 3 月是主要的蜂蜜收获季节,而 5 月至 7 月和 10 月至 12 月分别是次要的蜂蜜收获期。然而,由于缺乏意识和实际技能,大多数养蜂人每年只从所有蜂箱中收获一次蜂蜜。因此,我们建议地方政府应重点教育养蜂人,使他们能够充分利用多花季节和改良蜂箱技术的机会,最大限度地提高该地区的蜂蜜产量。
