Abstract
VIVA® is a biostimulant composed of polysaccharides, polypeptides, amino acids, selected humic acids and vitamins.
In order to evaluate its effect on the root activity and the development of the aerial part of commercial crops, a study with tomato plants was conducted.
Tomato plants, Solanum lycopersicum IKRAM, were treated twice with the biostimulant VIVA® during spring 2012, once at the moment of transplanting (third real leaf) and again 15 days post transplant.
In order to measure the biostimulant effect the phenotypic parameters were measured with the automated Scanalyzer 3D system (Lemnatec GmbH, Germany) at the Research Center of ALSIA in southern Italy.
The results demonstrated that double VIVA® treatments used on plants under drought stress had increased plant biomass byapproximately double with respect to untreated plants.
This result was confirmed by measuring the plant fresh biomass at the conclusion of the growth study.
Finally, roots treated with VIVA® had a greater distribution of root biomass with respect to those of non-treated plants.
