ABSTRACT
The research aimed to evaluate the combined effect of T. harzianum and FitoMas-E® on germination and growth of tomato seedlings. In the first test tomato seeds cv. Vyta they were used to treat with solutions FitoMas-E® (2.0 % v / v) and T. harzianum strain A-34 concentration of the solid medium of 1.7 x 109 CFU mL-1 . Germination percentage every six hours by placing 50 seeds per Petri dish of 10 cm diameter with five replicates per treatment is evaluated. In a second test the effect of inoculation of T. harzianum and FitoMas-E® on the growth of tomato seedlings in conditions rootball was evaluated, using trays 264 alveoli and substrate made from peat: soil: rice husks (3:2:1). Speed and percentage germination of tomato seeds treated FitoMas-E® and T. harzianum was found, combined use increases the values of stem diameter and total and radical mass, which can be exploited for transplanting plants tomato, generating a possible diminution in production costs.
