HIDALGO RODRIGUEZ, José Ernesto Manuel et al. Coinoculation of Rhizophagus irregularis and Rhizobium sp. in Phaseolus vulgaris L. var. canary (Fabaceae) "canary bean. Arnaldoa [online]. 2019, vol.26, n.3, pp.991-1006. ISSN 1815-8242.  http://dx.doi.org/10.22497/arnaldoa.263.26309.

Phaseolus vulgaris L. (Fabaceae) is one of the most important crops and one of the main protein sources. The objective of this research was to evaluate the effect of the inoculation of Rhizophagus irregularis and Rhizobium sp. on the growth and production of P. vulgaris. Plantlets were inoculated with both microorganisms and we measured the number of leaves, knots, stem diameter, shoot length, leaf area, fresh and dry weight, total protein content and yield components. Rhizobium sp. promoted plant growth, increasing the shoot diameter, dry weight, leaf area, total protein content and yield. Mycorrhizal fungi did not affect the number of knots, leaves, shoot length, protein content or fresh and dry weight. However, differences were observed in the yield components number and weight of seeds. Coinoculation with both microorganisms promoted an increase in the growth parameters (number of leaves, leaf area, fresh and dry weight, shoot length and stem diameter) and at the same time caused an increase in yield components (seed number and seed weight). It is concluded that the inoculation of both Rhizophagus irregularis and Rhizobium sp., promotes the growth, development and yield in Phaseolus vulgaris var. Canario "canary bean" under greenhouse conditions.
