Effect of Vermicompost Tea on Faba Bean Growth and Yield

Abstract

This study investigatecl the effect of vermicompost tea (VCT) as a natural foliar fertilizer in faba bean. To determine the effect of ver at different doses on the growth and reproduc tion of faba bean, ver was producecl and three different concentrations (0, 10, and 20% VCl) were appliecl as a foliar fertilizer to faba bean plants. Plant height, number of flowers, and pods per plant as well as soluble sugars were measurecl weekl y after treatment for a period of 11 weeks. Treatecl plants were larger and had more flowers per clump, as well as more clumps and pods per plant than the contrai. Moreover, treatecl plants reachecl the flowering stage at least 3 weeks earlier than the contrai. This could be explainecl by the presence of nutrients, humic acid, and probably hormones in ver, which may positively affect growth, reproduction, and yield. Treatment at 10% VCT presentecl better values than 20% VCT. The latter containecl more humic acid, which probably limitecl growth and flower ing. The soluble sugar and protein contents were higher in treatecl plants, and the highest values coincidecl with the flowering and reproductive stages. Similarly, seecls produced by treatecl plants were richer in protein that control seecls. These results indicate that 10% VCT is a useful fertilizer to improve growth in faba bean. This study highlights the possibility of using ver as a foliar fertilizer to increase growth in faba bean.

Fresh Compost Tea Application Does Not Change Rhizosphere Soil Bacterial Community Structure, and Has No Effects on Soybean Growth or Yield

“…Other studies performed on vermicompost tea or vermicompost leachate reported plant growth benefits and increased tolerance against abiotic stress. For example, Chaichi et al, 2018 [ 59 ] applied different concentrations of vermicompost tea ranging from 0% to 20%, as a foliar amendment in faba bean and they found that treated plants grow better than controls and had more flowers, clumps and pods per plant than non-treated pants [ 59 ]. Treatment at a concentration of 10% of vermicompost tea showed better results that 20%.…”

“…Treatment at a concentration of 10% of vermicompost tea showed better results that 20%. The authors attributed these growth benefits the presence of nutrients, humic acid and putative hormones in vermicompost tea [ 59 ]. Other reports showed vermicompost leachate, a method consisting of adding water to a large amount of vermicompost (e.g., 20 L of water for 50 kg of vermicompost) allowing the mixture to leachate for 48 h, alleviated salt stress in tomato plants which was also explained by phytohormones and presence of other compounds such as humic acid and antioxidants [ 60 , 61 ].…”

Synergistic effect of organic amendments and biostimulants on faba bean grown under sandy soil conditions

“…In addition, Dhary and Al-Baldawi (2017) showed that the application of organic fertilizers significantly increases yield of faba bean seeds. However, Chaichi et al (2018) indicated that vermicomposting tea is a useful fertilizer to improve growth in faba bean.…”

Production and use of homemade dry manure-based tea in fertigation systems in North Africa

“…Studies have documented the impacts of compost and vermicompost tea in suppressing pests and diseases (Scheuerell and Mahaffee, 2002). This tea can also have positive effects on crop physiology, growth and yield (Benitez et al, 1996;Pant et al, 2009;Gutiérrez-Miceli et al, 2011;Chaichi et al, 2018;Arancon et al, 2019;Ibrahim et al, 2019, and many others). Pant et al (2012) directly linked increased pak choi plant growth with the mineral N and gibberellin content of compost tea.…”
