Promotion of tomato growth by Pseudomonas putida PCI2 under hydroponic conditions

Abstract

Hydroponics is a production system in which the roots of plants are irrigated with a mixture of essential nutrients dissolved in water and, instead of soil, an inert mineral substrate or simply the same nutrient solution is used. Tomato cultivation (Solanum lycopersicum L.) is adapted to hydroponic cultivation and it is necessary that it be developed in conditions that are friendly to the environment and health. The use of microorganisms that promote the growth and health of crops constitutes a global trend in this sense. Pseudomonas putida PCI2 is a strain isolated from the tomato rhizosphere and on which tests were carried out regarding its beneficial interaction with crops, linked to the mobilization of nutrients, production of phytohormones and suppression of diseases. The objective of this work was to evaluate the growth promoting capacity of P. putida PCI2 in tomato crops under hydroponic conditions.
