Influence of organic biostimulants on morphological and biochemical traits of radish

Abstract

The aim of this study was to evaluate the effects of different organic biostimulants on the morphological traits and quality parameters of radish under controlled growing conditions. The experiment was conducted with three replications and five treatments: Levoamin, Algafert, yeast, humic acids, and a control. The results showed that the application of biostimulants significantly affected all analysed morphological traits compared to the control. The highest values for plant height, total plant mass, and root dimensions were recorded in treatments with Levoamin and yeast. The application of biostimulants increased vitamin C content, total phenolic compounds, total antioxidant capacity, and total chlorophyll content. The most pronounced effect occurred with the yeast treatment, which recorded the highest values of total phenols and antioxidant capacity. The results indicate that applying organic biostimulants, particularly yeast, can significantly improve the growth and nutritional quality of radish.
