Abstract

Abstract This study investigated the effect of vermicompost tea (VCT) as a natural foliar fertilizer in faba bean. To determine the effect of VCT at different doses on the growth and reproduction of faba bean, VCT was produced and three different concentrations (0, 10, and 20% VCT) were applied as a foliar fertilizer to faba bean plants. Plant height, number of flowers, and pods per plant as well as soluble sugars were measured weekly after treatment for a period of 11 weeks. Treated plants were larger and had more flowers per clump, as well as more clumps and pods per plant than the control. Moreover, treated plants reached the flowering stage at least 3 weeks earlier than the control. This could be explained by the presence of nutrients, humic acid, and probably hormones in VCT, which may positively affect growth, reproduction, and yield. Treatment at 10% VCT presented better values than 20% VCT. The latter contained more humic acid, which probably limited growth and flowering. The soluble sugar and protein contents were higher in treated plants, and the highest values coincided with the flowering and reproductive stages. Similarly, seeds produced by treated plants were richer in protein that control seeds. These results indicate that 10% VCT is a useful fertilizer to improve growth in faba bean. This study highlights the possibility of using VCT as a foliar fertilizer to increase growth in faba bean.
蚯蚓堆肥茶对蚕豆生长和产量的影响
摘要研究了蚯蚓堆肥茶(VCT)作为蚕豆叶面天然肥料的施用效果。为了确定不同剂量的VCT对蚕豆生长和繁殖的影响,制备了VCT,并将三种不同浓度(0、10%和20%)的VCT作为蚕豆叶面肥施用于蚕豆植株。处理11周后,每周测量株高、花数、单株荚果数以及可溶性糖。与对照相比,处理过的植株更大,每簇花更多,每棵植株的簇和豆荚也更多。此外,处理植株比对照至少提前3周进入花期。这可能是由于VCT中存在营养物质、腐植酸,可能还有激素,它们可能对生长、繁殖和产量产生积极影响。10% VCT的治疗效果优于20% VCT。后者含有更多的腐植酸,这可能限制了生长和开花。可溶性糖和蛋白质含量在处理植株中较高,且在开花期和繁殖期最高。同样,经过处理的植物产生的种子富含控制种子的蛋白质。结果表明,10% VCT是促进蚕豆生长的有益肥料。本研究强调了利用VCT作为叶面肥料促进蚕豆生长的可能性。
