Abstract

This article examines the effect of various doses of biostimulants on the stem growth and leaf formation of the “Dilbar” oilseed sunflower variety during its developmental phases. The biostimulants “Fitovak 20%”, “Biodux”, and “MERS” were used, with a control group and a group treated with the biostimulant “Uzgumi” serving as a standard. A comparative analysis showed that the immunostimulant “Fitovak 20%” resulted in taller and more robust stem growth and a greater number of leaves compared to the biostimulants “Biodux” and “Mers”.
