Effect of rhizobacteria and reduced doses of synthetic fertilizers on the morpho-productive expression of tomato in greenhouse

Abstract

The use of rhizobacteria as promoters of plant growth in agricultural production is considered an eco-logically viable alternative to the excessive use of synthetic fertilizers. The effect of the inoculation of two rhizobacterial strains of Pseudomonas putida and application of two concentrations of synthetic fertilization on the morpho-productivity expression of tomato plants (Solanum lycopersicum M.) in greenhouse was determined. The plants were inoculated with strains FA-8 and FA-56 by immersion of the root sys-tem. The synthetic fertilization supplied was 100% and 75% concentration. The height, stem diameter, root length and volume, biomass, yield, total soluble solids (TSS) and rhizobacterial population were de-termined. The results indicate that two strains of P. putida and two levels of synthetic fertilization sig-nificantly promoted the morpho-productive parameters of the plants. The application of P. putida in tomato plants represents a potential alternative as a bio-fertilizer in sustainable production.
