A field experiment to assess the response of soybean to the application of TS series stimulators was set up as complete blocks design with four replications. The investigated factor was growth stimulators (seed dressing – TS Osivo and foliar – TS Samson) produced by the Czech company BEIDEA s.r.o., com-pared to the control (without a stimulator). The reason behind the study was the lack of domestic reports regarding the impact of the use of TS series stimulators on the growth, development and morphological agronomic traits and yields of legume crops. The field trials were carried out in 2018–2019 at the Research Station operated by the Institute of Agroecology and Plant Production, Wrocław University of Environmental and Life Sciences, located in the district of Wrocław – Pawłowice (Dolnośląskie voivode-ship). The tested crop was soybean, cultivar Abelina (maturity group 000 ++, breeder Saatbau Linz).Soybean seed dressing with TS Osivo stimulator caused an acceleration of germination and emergence phases from 2 to 4 days compared to the control treat-ment (water). The use of TS series stimulators in soybean culti-vation contributed, in comparison to the control, to a significant increase (by 7.5%) in the plant height before harvest. Simultane-ously, an increase in the height of first pod was observed, which reduces seed losses during harvest. Seed treatment with the TS Osivo stimulator increased seed yield by 5.8% compared to con-trol treatment (without application). Spraying soybean with TS Samson stimulator increased the seed yield by 8.6%. In practice, in order to achieve an increase in soybean seed yield it is recom-mended to apply pre-sowing seed treatment with TS Osivo stimu-lator or foliar application of TS Samson.
