Currently, the unchecked increase in human population results in increased demand for agricultural lands. Growing two or more crops simultaneously is one of the mechanisms to reduce this problem. A field experiment was conducted in northwestern Ethiopia during 2017 and 2018 cropping seasons. Two legume crops [haricot bean (Phaseolus vulgaris) and lupine (Lupinus angustifolius)] were intercropped with finger millet (Eleusine coracana) using two intercrop planting methods (row and mixture) and three finger millet-legume planting ratios (100.0%:75.0%, 100.0%:50.0% and 100.0%:25.0% of the respective recommended seed rate of sole crops). Two sole crop finger millets (planted in rows and broadcast) and two sole legume crops (haricot bean and lupine) were included as checks. The experiment comprised a randomized complete block design with three replications. Results indicated intercropped finger millet and total land output yield from finger millet-haricot bean row intercropping at a 100:50 planting ratio and sole finger millet planted in a row improved better yield stability. Finger millet-haricot bean row intercropping at a 100:50 planting ratio also resulted in higher grain yields of the component crops, area time equivalent ratio (1.34), relative production (38.1%) and economic (314.0%) efficiencies with a relatively lower component crop competitive ratio. Thus, this cropping system offered increased productivity and economic return and is a viable option for increasing household food security.

小米与豆类添加剂设计间作的竞争、生产效率和产量稳定性

目前，人口的无节制增长导致对农业用地的需求增加。同时种植两种或多种作物是减少这一问题的机制之一。2017 年和 2018 年种植季节在埃塞俄比亚西北部进行了田间试验。两种豆类作物[扁豆（菜豆) 和羽扇豆 (羽扇豆)] 与指谷间作 (Eleusine coracana) 采用两种间作种植方法（行和混合）和三种指小米豆类种植比例（100.0%:75.0%、100.0%:50.0% 和 100.0%:25.0% 各自推荐的单一作物播种率）。包括两种单一作物手指小米（成排种植并播种）和两种单一豆类作物（扁豆和羽扇豆）作为检查。该实验包括具有三个重复的随机完整区组设计。结果表明，以100:50的种植比例进行间作的小粟和小扁豆行间作以及连续种植的单小粟提高了更好的产量稳定性。以 100:50 播种比进行的小米-扁豆行间作也导致组成作物的谷物产量、面积时间当量比 (1.34)、相对产量 (38. 1%）和经济（314.0%）效率与相对较低的成分作物竞争比。因此，这种种植系统提供了更高的生产力和经济回报，是提高家庭粮食安全的可行选择。
