Effects of Different Nanoscale Microelement-Containing Formulations for Presowing Seed Treatment on Growth of Soybean Seedlings

Effects of nanoscale microelement-containing formulations for presowing seed treatment on germination and growth of soybean were studied. The formulations were prepared based on some well-known commercial products such as Doktor Tarsa Company and Wuxal Company. The results showed that all the tested formulations demonstrated noticeably higher stimulation effects on germination and soybean seedlings growth, among which the nanosized Co- and MoO3-containing formulations exhibited the highest growth indices compared with the control (overpassed by about 10%), asserting the role of Co and Mo together with biostimulants as an effective nutrient mixture for growth and development of soybean plants. Enzymatic analysis of the nanotreated soybean shoots also demonstrated a similar feature; the studied formulations exhibited higher amylase and lipase activities compared with those of the control.
