Evaluation of the Effect of Azospirillum brasilense and Mycorrhizal Fungi of the Soil in Yacon Grown in a Greenhouse

Abstract

In order to evaluate the effect of Azospirillum brasilense and mycorrhizal fungi in the soil on the nutrition of the yacon crop (Smallanthus sonchifolius [(Poeppig & Endlicher) H. Robinson]), determinations of agronomic parameters and the health status of the plants were carried out, under greenhouse conditions. The tests were carried out at the time of the implantation of the culture: the propagules were inoculated with A. brasilense and with native mycorrhizal fungi, generating four treatments, including the control and the co-inoculation of the consortium of the microorganisms under study (T0: control or control without inoculation; T1: inoculation with native A. brasilense; T2: inoculation with native mycorrhizal fungi and T3: joint inoculation with A. brasilense and native mycorrhizal fungi. The results indicate that co-inoculation with A. brasilense and native mycorrhizal fungi increased plant growth in height, leaf area, biomass, dry matter and yields significantly in greenhouse production. It was determined that the application of the selected microorganisms has a plant growth promoting effect, increasing growth and productivity, greenhouse grown yacón.

Aplicación de extractos de algas, NP’SZnO y microorganismos sobre la biomasa vegetal en tomate

“…Con referencia al peso seco de la planta, la aplicación de rizobacterias en los cultivos hortofrutícolas ha mostrado efectos positivos, estos se reflejan en la mayor producción de fibra (Delgado-Ramírez et al 2021). La aplicación de microorganismos en coinoculación entre A. brasilense con Glomus intradices mejora el peso seco de hoja, tallo y raíz de Yacón, además de incrementar la calidad bromatológica y el porcentaje de cantidad de fibra acumulada en el cultivo (Di-Barbaro et al 2021). Esta misma combinación, en rábanos incrementó el peso seco de hojas y de raíz (Rodríguez-Larramendi et al 2020).…”
