Inoculação com Azospirillum brasilense na cultura do tomateiro

Abstract

This work aimed at a direct interaction with the use of human resources, the effect on their morphological, productive and development. The experiment was carried out in a randomized complete block design with two replicates in a 2 x 5 factorial scheme, with two tomato cultivars with four inoculant doses (0, 2, 4, 6 and 8 mL kg-1 of seeds) containing as Ab-V5 and Ab-V6 strains. The first experiment was carried out at home, in the greenhouse located at the Federal University of Southern Border (UFFS) Campus of Laranjeiras do Sul, PR. As variables analyzed were: root length (cm); root volume (cm³); plant height (cm); stem diameter (mm); SPAD Index; dry mass of shoot and root (g) The second experiment was developed in a field in the municipality of Quedas do Iguaçu, being evaluated as alias of plant height at 30 and 60 DAT and eminent plant crop. The results obtained in this study demonstrated that costs with nitrogen fertilization through an inoculation are more difficult and that the same characteristic of a tomato studied could have a beneficial relation with a bacterium. This tomato interaction with Azospirillum brasilense originated Main gains of dry mass, volume and root length greater stem diameter, height, SPAD index and higher yield per plant.
