Abstract

Weeds significantly hinder mung bean production in Ethiopia. A field experiment conducted during the 2022 cropping season in Guragie Zone investigated the impact of pre- and post-emergence herbicides on weed control and mung bean (Vigna radiata (L.)) yield. The experiment utilized a randomized complete block design with three replicates and four treatments. The study revealed that the interaction between location and weed control methods significantly influenced weed density, dry weight, and control efficiency. Additionally, location and weed control methods significantly affected various mung bean growth parameters, including days to flowering and maturity, plant height, pod and seed numbers per plant, and grain yield. Meskan Wordea produced significantly higher pods per plant (14.4) and seeds per pod (9.73). Meanwhile, the weed-free check yielded the maximum number of pods per plant (20.38) and seeds per pod (11.68). Conversely, the weedy check exhibited the lowest values (7.17 pods and 6.43 seeds per pod). The weed-free check also achieved the highest grain yield (1412.9 kg ha−1), aboveground dry biomass (3309.2 kg ha−1), and harvest index (42.94%). Conversely, the weedy check yielded the lowest values. Financial analysis revealed that the combined application of Quizalofop-p-ethyl + Bentazone herbicide in Ezeha location resulted in the highest net profit (33602.3 ETB ha−1). Therefore, for optimal mung bean growth and yield in the study area, we recommend planting the Rasa variety with Quizalofop-p-ethyl + Bentazone herbicide in Ezeha location.
Quizalofop-p-ethyl + Bentazone 和 Pendimethalin 除草剂对埃塞俄比亚中南部 Guragie 区绿豆(Vigna radiata (L.) Wilczek)杂草、产量成分和产量的影响
杂草严重阻碍了埃塞俄比亚的绿豆生产。2022 年耕种季节在 Guragie 区进行的一项田间试验调查了萌发前和萌发后除草剂对杂草控制和绿豆(Vigna radiata (L.))产量的影响。试验采用随机完全区组设计,设三个重复和四个处理。研究表明,地点和杂草控制方法之间的交互作用对杂草密度、干重和控制效率有显著影响。此外,种植地点和杂草控制方法对绿豆的各种生长参数也有显著影响,包括开花和成熟天数、株高、单株结荚数和种子数以及谷物产量。Meskan Wordea 的单株豆荚数(14.4 个)和单株豆荚种子数(9.73 粒)均明显较高。同时,无杂草对照每株结荚数(20.38)和每荚种子数(11.68)最高。相反,杂草对照的产量最低(每荚 7.17 个豆荚和 6.43 粒种子)。无杂草对照的谷物产量(1412.9 千克/公顷-1)、地上部干生物量(3309.2 千克/公顷-1)和收获指数(42.94%)也最高。相反,杂草对照的产量最低。财务分析表明,在埃泽哈地区联合使用 Quizalofop-p-ethyl + Bentazone 除草剂的净利润最高(33602.3 ETB ha-1)。因此,为了使绿豆在研究地区获得最佳生长和产量,我们建议在埃泽哈地区种植 Rasa 品种,同时使用 Quizalofop-p-ethyl + Bentazone 除草剂。
