Crop diversification on the farm is a useful approach, especially in developing countries, where agriculture is the primary source of income. Crop diversity management on the farm is critical for reducing poverty, increasing farm revenue, creating jobs, and ensuring long-term agricultural sustainability by maintaining biodiversity, soil, and water resources. Despite their relevance, several variables are currently affecting farmers' crop production decisions. The purpose of this research was to see how socioeconomic factors influence crop diversification. We chose randomly 84 sample household heads from four kebeles to collect socioeconomic and on-farm data. The Shannon-Wiener index (SWI) and crop species richness were used to assess crop diversity. A multiple stepwise linear regression model was used to evaluate the data. Crop diversity was positively and significantly related to household farm size, animal size and composition, annual income, and the location's altitudinal gradient. A lack of road infrastructure and market connections constrained farmers' crop diversification options. It's vital to connect distant areas with road networks and market ties to promote farm-level crop diversification.
农场作物多样化是一种有益的方法，尤其是在农业是主要收入来源的发展中国家。农场作物多样性管理对于减少贫困、增加农场收入、创造就业以及通过维护生物多样性、土壤和水资源确保农业长期可持续性至关重要。尽管它们具有相关性，但目前有几个变量正在影响农民的作物生产决策。本研究的目的是了解社会经济因素如何影响作物多样化。我们从四个社区中随机选择了84个样本户主，以收集社会经济和农场数据。香农-维纳指数（SWI）和作物物种丰富度用于评估作物多样性。使用多元逐步线性回归模型对数据进行评估。作物多样性与家庭农场规模、牲畜规模和组成、年收入以及所在地的海拔梯度呈正相关且具有显著相关性。道路基础设施和市场联系的缺乏限制了农民的作物多样化选择。通过道路网络和市场联系连接偏远地区对于促进农场层面的作物多样化至关重要。
