Vegetative growth of strawberry through the use of growth promoters.

The objective of this study was to evaluate the effects of inoculation and co-inoculation of Trichoderma and rhizobia, and the incorporation of silicon, with and without the combination of the inoculants, on the vegetative growth in strawberry seedlings. The experimental design was carried out in randomized blocks, with treatments and four replicates, and two plants per replicate. They were found at 22 and 55 days after transplantation. The treatment with Trichoderma significantly influenced the variables 'crown diameter' and 'crown dry mass', while silicon treatment influenced the variables 'root area', 'fresh root mass', 'root dry mass', 'leaf fresh mass' and 'shoot fresh mass'. The different differences cannot be separated for different treatments. It was concluded that silicon, when inoculated or associated with other inoculations, did not have a great influence on the evaluated variables, whereas Trichoderma did not influence the accumulation of matter in the crown, and the incorporation of itself as a beneficial element to the vegetative development of the strawberry. Also, a "root" variable has a high frequency with the other variables.
