OPCIONES DE MANEJO SOSTENIBLE DEL SUELO EN ZONAS ARIDAS: APROVECHAMIENTO DE LA HALÃ“FITA Salicornia bigelovii (Torr.) Y USO DE BIOFERTILIZANTES EN LA AGRICULTURA MODERNA
subject: Plant growth promoting bacteria, Salinity, promising plant resources
description: The study and development of plant resources in arid-saline environments is increasing. Salicornia bigelovii is a halophyte of great interest. However, the productivity of these plants is limited by nitrogen availability. An alternative to chemical fertilizers are the plant growth promoting bacteria and mycorrhizae. In the present study was evaluated the effect of Glomus intraradices, three strains of rhizobacteria (Klebsiella pneumoniae, Bacillus amyloliquefaciens and Azospirillum halopraeferens) and two soil types (clayey and sandy) on Salicornia under greenhouse conditions. The inoculation of bacteria under conditions of sandy soil significantly stimulated growth and nutritional factor of Salicornia (NPK). Synergism was observed between G. intraradices and rhizobacteria. When inoculated bacteria in individually form, behaved with significant differences. There was synergism between G. intraradices and Klebsiella pneumoniae and A. halopraeferens in the uptake of N, the opposite happened with G. intraradices and Bacillus amyloliquefaciens with high significant values in the absorption of P and K. The soil was a determining factor in behavior and expression of the benefit of the microorganisms. Rhizobacteria and mycorrhiza in the study have potential for use as growth promoters in salicornia.
