Abstract

In «Liliana Dimitrova» Horticultural Investigation
Institute, an experiment was developed during 1996-2000 with
the variety of tomato HC 38-80 sown late in the season. In the
seedling phase, a screening was accomplished, with the
objective of selecting the most efficient arbuscular mycorrhizal
fungi strains and rhizobacteria to the tomato crop, as well as
the best combinations. Therefore, plant height, stem diameter,
root length and total dry weight were determined. Later on, the
effect of biofertilizers selected and mineral fertilization on crop
yield, its components and plant nutritional status were
evaluated. The greatest values recorded in the seedling phase
corresponded to strain inoculation with Glomus mosseae,
Glomus fasciculatum, Azospirillum brasilense, Azotobacter
chroococcum, Glomus mosseae + Pseudomonas fluorescens
and Glomus mosseae + Azospirillum brasilense. Yield and its
components were benefited with the application of optimum
fertilizer levels, while the greatest values for the inoculated
treatments corresponded to Glomus mosseae, Glomus mosseae
+ Pseudomonas flourescens and Glomus mosseae +
Azospirillum brasilense combined with 50 % N fertilization.
The arbuscular mycorrhizae and its inoculation with growth
promoting rhizobacteria stimulated nitrogen and phosphorus
absorption.
