Selection of a growth promoter microbial consortium in onion seedlings under shade-house conditions

The practice of producing more vigorous seedlings represents a competitive advantage at the time transplanting crop, and use combined biofertilizers are sustainable ecological alternative. objective this research was to select microbial consortium for production F1 2000 hybrid onion seedbeds under shade-house conditions. Five rhizobacterial strains genera Rhizobium (ME01 strain), Bradyrhizobium (Leu2A YE1 strains), Ochrobactrum (ES1 strain) Pseudomonas (Alf which have shown favorable effects on pepper lettuce seedlings. These rhizobacteria were inoculated in mixed manner (microbial consortium) as follows: Alf+ES1, ME01+ES1, ES1+Leu2A, Alf+Leu2A, YE1+ES1, ME01+Alf, YE1+Alf, ME01+YE1, YE1+Leu2A, ME01+Leu2A, using soil from San Juan de Lagunillas-Mérida, Venezuela conditions 60 days. following variables determined: number leaves, pseudostem base diameter, aerial root length, fresh dry weight. Additionally, CO2 assimilation curve different light levels carried out selected observe their photosynthetic response. ME01 + Leu2A (Rhizobium tropici japonicum) increased all studied variables, especially essential cultivation, yielded higher rates. is recommended an option agricultural seedbed
