Abstract
The formation of a healthy root system for plants is an essential requirement for good crop yield.
The production of secondary roots, those necessary for nutrient uptake, are of particular importance.
It has been shown that the administration of some biostimulant products to young rye plants determined a significant increase in the chlorophyll levels and the regenerative capacity of the roots (Russo et al., 1990). Therefore from a nutritional point of view, biostimulants can promote plant growth, modify root architecture, increase root development which in turn predispose the plant toward a greater capacity for the absorption of nutrients.
With respect to these results, a new study with tomato plants was conducted to measure the effect of Radifarm® on root development via image analysis.
Tomato plants were grown in clear plexiglass tubes files with earth permitting the monitoring of root system development without disturbing the plant.
Results from the analysis showed that a double Radifarm® treatment program (root bath and a subsequent irrigation with diluted Radifarm®) resulted in the development of a greater root system and an increased presence of secondary roots.
In addition, soil analysis with near infrared illumination, which permits the measurement of water presence in the soil, showed that plants treated with the same double application regime of Radifarm® also had a greater absorption capacity.
