| description | Agricultural soils for the cultivation of short-cycle plant species, lack organic matter as a result of the excessive use of agrochemicals. These soil fertilizers of chemical origin cause changes in soil structure and biodiversity. The use of rhizobacteria in agriculture improves legume crop productivity through the formation of a rhizobia-plant symbiosis allowing nitrogen fixation. The aim of this study was to evaluate the effect of Bradyrhizobium japonicum, Pseudomonas fluorescens CHA0 and Pseudomonas veronii R4 in promoting soybean: ICA-P34; INIAP-308; INIAP-307 development and increased productivity. At 7 and 30 days, root growth and nodule formation was evaluated, by co-inoculation of rhizobacteria and without inoculants, performance was also determined in kgha-1. Under in vitro conditions root tissue increases with 5, 3 and 9 cm, per B. japonicum in, ICA-P34, INIAP-308 and INIAP-307. In seedling, 21 and 20 cm roots were observed in INIAP-307 with P. veronii R4 and P. fluorescens CHA0. 10, 14 and 10 nodules per plant were obtained in the three varieties with B. japonicum. No nodule formation was observed after Pseudomonas spp application. Grain yield per hectare was 3700, 2890, and 3929 kgha-1, with B. japonicum and without bacterial inoculum yields fall to 2006, 1611 and 1842 kgha-1. B. japonicum colonizes the root system and generates morphological and physiological changes, which positively increase yield in soybean seeds. |

Los suelos agrícolas destinados al cultivo de especies vegetales de ciclo corto, carecen de materia orgánica por efecto del excesivo empleo de agroquímicos, estos fertilizantes edáficos de origen químico ocasionan cambios en la estructura y la biodiversidad del suelo. La incorporación de rizobacterias en la agricultura permite mejorar la productividad de cultivos de leguminosas por la formación de un complejo de simbiosis rhizobio-planta que permite la fijación de nitrógeno. El objetivo del presente trabajo fue evaluar el efecto de Bradyrhizobium japonicum, Pseudomonas veronii R4 y Pseudomonas fluorescens CHA0 para promover el desarrollo e incremento de productividad en tres variedades de soja: ICA-P34; INIAP-308; INIAP-307. A los 7 y 30 días se evaluó el desarrollo radicular y formación de nódulos, por co-inoculación de rizobacterias y sin inoculantes, también se determinó el rendimiento en kgha-1. En condiciones in vitro se incrementó el tejido radicular con 5, 3 y 9 cm de largo, por B. japonicum en ICA-P34, INIAP-308 y INIAP-307. En plántulas se observó raíces de 21 y 20 cm en INIAP-307 con P. veronii R4 y P. fluorescens CHA0. Inoculando las tres variedades con B. japonicum, se obtuvo 10, 14 y 10 nódulos por planta, cuando se aplicó Pseudomonas spp no existió formación de nódulos. El rendimiento de granos por hectárea fue 3700, 2890 y 3929 kgha-1, con B. japonicum, sin inoculo bacteriano los rendimientos disminuyen a 2006, 1611 y 1842 kgha-1. B. japonicum coloniza el sistema radicular influyendo con cambios morfológicos y fisiológicos, que positivamente incrementa el rendimiento en semillas de soja.
