摘要

本试验于2015年和2016年短雨季在波尔农业研究中心(BOARC)阿多拉分站进行,目的是确定普通豆引进玉米和普通豆间作的最佳时机和选择最佳普通豆品种。试验采用随机完全区组设计(RCBD),对3个普通豆品种(原屋、伊巴多和哈瓦萨杜姆)进行因子组合3个重复,4次间作(同时与玉米、2个WAME、4个WAME和6个WAME),分别与普通豆品种和玉米bh661单作。品种与间作时间对开花、成熟天数和株高的互作效应极显著,其中普通豆品种同期间作比延期间作的开花和成熟天数更长,生长更高、更健壮。间作时间对豆荚-1和种子-1的数量有极显著的影响,其中与玉米同时种植的豆荚-1的平均数量最高。在普通豆品种中,间作品种和间作时间对百粒重和籽粒产量也有极显著的互作效应,其中由于间作延迟,百粒重和籽粒产量显著降低。在玉米各组分中,间作时间的主效应仅对株高和籽粒产量有显著影响,其中平均株高和籽粒产量最高的是间作延迟时间的普通豆。间作时间的主效应对大豆和玉米的总lerv和GMV有显著影响。普通豆与玉米同时间作的LER和GMV分别为1.36和20246 ETB ha-1。因此,根据观察到的生产力和经济效益,在谷集中部地区和类似的农业生态系统中,可推荐普通豆与玉米同时间作。

Effect of Variety and Time of Intercropping of Common Bean (Phaseolus vulgaris L.) With Maize ( Zea mays L.) on Yield Components and Yields of Associated Crops and Productivity of the System at Mid-Land of Guji, Southern Ethiopia
The field experiments was carried out at Bore Agricultural Research Center (BOARC) on Adola Sub-site, during 2015 and 2016 short rainy season with the objective of determining the most suitable time of introducing common bean and select the best common bean variety into maize and common bean intercrop. The experiment was laid out in randomize complete block design (RCBD) with three replications of factorial combination of three common bean varieties (Haramaya, Ibbado and Hawassa Dume) and four time of intercropping (Simultaneously with maize, 2 WAME, 4 WAME and 6 WAME) along with respective sole crops of common bean varieties and maize BH-661. Highly significant interaction effect of variety and time of intercropping were observed on days to flowering, maturity and plant height, whereby simultaneous intercropping of common bean variety provide longer days to flowering and maturity with taller and vigorous growth than delayed intercropping. A highly significant effect of time of intercropping was observed on number of pod plant-1 and seed pod-1, in which the highest mean number were recorded when common bean was simultaneously planted with maize compared to subsequent interseeding. Highly significant interaction effect of variety and time of intercropping were also observed on common bean varieties on hundred seed weight and grain yields, where drastic reduction of hundred seed weight and grain yields were observed due to delayed intercropping. In regards to maize components, only plant height and grain yield were significantly affected by main effect of time of intercropping, in which the highest mean plant height and grain yield were recorded in delayed time of intercropping common bean. On other hand total LER and GMV of Common bean and maize were significantly affected by main effect of time of intercropping. Simultaneous intercropping of common bean with maize proved LER and GMV of 1.36 and 20246 ETB ha-1, respectively. Therefore, simultaneous intercropping of common bean with maize could be recommend for midland of Guji and similar agro-ecology, based on the observed productivity and economic benefit.
