INFLUENCE OF TWO BIOSTIMULANTS APPLICATION ON GROWTH AND DEVELOPMENT OF TROPAEOLUM MAJUS L.

Abstract

The effect of two different biostimulants was inevstigated in this study on growth and development of nasturtium (Tropaeolum majus L.). Biostimulants Radifarm® and Megafol® were applied according manufactures advice. The experiment was conducted in 2013. It was arranged in a split - plot design with four replicates and three treatments (control, Radifarm®, Megafol®). Morphological parameters, plant height, leaf number and number of flowers were recorded regularly during growth and development of nasturtium. At the end of experiment, plants were sampled and root and above-ground fresh and dry weight and root length were recorded. Obtained results showed significantly higher values of all investigated parameters of nasturtium growth under tretament with biostimulants.The research shows that applying biostimulants in the production of Tropaeolum majus L. improves the growth and development of the root and the above-ground part.
