SOLUBILIZADORES DE FOSFATOS PARA INCREMENTO DE PRODUTIVIDADE DE TOMATE CEREJA (Solanum lycopersicum L. var. cerasiforme) Monografia

Abstract

The tomato fruit is considered one of the most nutrient-demanding vegetables, as its nutrient uptake efficiency is relatively low. In this context, the use of phosphate-solubilizing microorganisms (PSM) emerges as a promising strategy to address challenges related to phosphorus adsorption. This study aimed to evaluate the agronomic parameters and phosphorus accumulation in the cherry tomato crop. The experiment was conducted in a greenhouse at the Federal Institute of Goiás – Rio Verde Campus, GO, in a randomized block design with four replications. The treatments were: control (no inoculation), Pseudomonas fluorescens (commercial product), Bacillus megaterium + Bacillus subtilis (commercial product), Scleroderma citrinum, and Ralstonia sp. Data were subjected to analysis of variance, and means were compared using the Scott–Knott test at a 5% significance level. Ralstonia sp. was the most efficient treatment, promoting simultaneous increases in yield-related variables (shoot and root length, fresh and dry root mass, stem diameter, fresh fruit mass, and fruit number) and phosphorus accumulation in fruits and shoots. Ralstonia sp. and Scleroderma citrinum showed increases in fruit dry mass, while Pseudomonas fluorescens was effective in enhancing phosphorus accumulation in roots. For production and phosphorus accumulation variables, inoculated treatments showed better responses compared to the non-inoculated control.
