Co-inoculation with a product based on native microorganisms improves germination and seedling growth of Phaseolus vulgaris L.

Abstract

Agricultural products based on native microorganisms represent an ecological alternative to traditional chemical fertilizers for enhancing growth and crop yield. This study aimed to evaluate the effect of the product based on native microorganisms IHPLUS® on germination, emergence, and primary leaf formation of Phaseolus vulgaris L. seedlings. The treatments consisted of a control (immersion in distilled water) and nine treatments that were the combination of IHPLUS® at three concentrations and three immersion times. The application of IHPLUS® significantly increased the percentage of germination, mainly in the first days. After 7 d, the germination rate and root and hypocotyl lengths increased in almost all treatments compared to control seedlings. The beneficial effects of IHPLUS® on the germination of P. vulgaris may be partially attributed to changes on seedling metabolism due to an increase in α-amylase activity and in the content of reducing sugars and soluble proteins. Results suggest that IHPLUS® may act as an enhancer of germination in common beans that might lead to rapid seed germination, uniform seedling growth, and better seedling establishment and crop productivity.

“…(2018) reportaron que es efectiva la sustitución hasta used in agriculture for their beneficial effect on the growth and productivity of several plant species, such as tobacco (Calero-Hurtado et al, 2019) and beans (Calero-Hurtado et al, 2020). Another study was reported by Díaz-Solares et al (2019) who used IH-Plus® to improve sorghum and reported very encouraging results for this species. Thus, the use of these organic products is important in nutrient management in integrated livestock-agriculture systems, in addition to making a correct use of the utilization of the resources available on the farm and once again demonstrating that diversified and integrated systems place greater emphasis on the optimal use of the available local resources.…”

“…Los mismos se han utilizado en la rama de la agricultura por su efecto benéfico en el crecimiento y la productividad de varias especies de plantas, como el tabaco (Calero-Hurtado et al, 2019) y en frijol (Calero-Hurtado et al, 2022). Otro estudio fue el reportado por Díaz-Solares et al (2019), quienes emplearon el IH-Plus® para to animal grazing. However, from the first year on, production began to be obtained from several crops that were planted in this area for self-consumption.…”
