Biostimulant Effects of Cladophora glomerata and Limnospira platensis on Growth and Rhizosphere Activity of Mentha spicata

Öz

This study aims to assess the biological properties of rhizosphere soil and the growth performance of Mentha spicata through the application of macroalgae and microalgae, promoting sustainable agriculture and environmental conservation. Seedlings were treated various concentrations (0%, 0.2%, 0.4%, and 0.6%) of C. glomerata as a macroalgae source and L. platensis as a microalgae source. Applications were carried out at 15-day intervals, starting one month after sowing. While the treatments varied in their effects on these growth factors, they significantly enhanced plant metrics compared to the control group. The highest chlorophyll content in leaves was achieved with the combined application of Cladophora glomerata (0.6%) and Limnospira platensis (0.6%). The findings demonstrated that microalgae and macroalgae treatments not only improved plant growth but also significantly increased β-glucosidase and dehydrogenase enzyme activities in the rhizosphere compared to the control (p<0.05). Additionally, soil chlorophyll levels were markedly elevated by algal treatments (p<0.05). The results showed that the combined application of C. glomerata and L. platensis is a promising biostimulant approach for improving mint growth and soil biological activity.
