摘要

在埃塞俄比亚,辣椒(Capsicum annuum)是一种重要的经济和传统作物。它也是埃塞俄比亚阿姆哈拉民族地区州小农所必需的蔬菜作物。这种作物的产量低于国家水平,据说每公顷7.36吨。它甚至低于阿姆哈拉民族区域邦的全国种植地区。本研究的重点是辣椒种植面积评估和病害收集及病害鉴定。根据可达性、生产和问题、可用时间、物流和代表性,有目的地选择了三个地区。在每个区选出三个具有代表性的农民管理机构。抽样的kebeles和受访者采用简单的随机抽样技术进行选择。共选取135名受访者进行访谈。数据是通过半结构化访谈计划收集的。在每个PA中,选取三个简单随机样本的农民田地进行评估。评价在植株的一个生长阶段(开花-结荚期)进行。收集的数据采用描述性统计进行分析。本研究的结果证实,在所有被调查的农民农场中,只有一种品种(Marekofana)遭遇了不同叶、茎和根病害的低至高水平侵袭。几乎所有调查地区都存在根腐病/枯萎病复合病害。病害患病率高,因此辣椒枯萎/根腐病复发率高;应更好地努力整合多种控制选择。

Pepper Disease Assessment and Identification in Major Growing Districts of West Gojam Zone in Northwestern Ethiopia
Hot pepper (Capsicum annuum) is an economically and traditionally an important crop in Ethiopia. It is also necessary vegetable crop mainly for small-scale farmers in Amhara National Regional State of Ethiopia. The productivity of this crop is low under national level, it is said to be 7.36qt per hectare. It is even lower to that of the national in Amhara National Regional State growing areas. Assessing pepper growing areas and collect damaged plants by the disease and identification of diseases was the focus of this study. Three districts were selected purposively based on accessibility, production and problem, available time, logistics, and representativeness. In each district three representative peasant administrations (PAs)/kebeles were selected. Sampled kebeles and respondents were selected using simple random sampling techniques. A total of 135 respondents were selected for interview. The data was collected through semi structured interview schedule. In each PA, three simple random sample selected farmers’ fields were assessed. The assessment was done at one growth stage of the plant (flowering-podding stage). The collected data was analyzed using descriptive statistics. The findings of this study confirm that in all the surveyed peasant farms, only one type of variety, which is Marekofana was encountered with low to high levels infestation of different leaf, stem, and root diseases. Root rot/wilt complex diseases were found distributed in almost all the surveyed areas. The prevalence of the disease, pepper wilt/root rot complex is high, therefore; efforts better to be made towards the integration of multiple control options.
