AbstractA field experiment was carried out in 2013-2016 in the Agricultural Experimental Station – Zawady of the University of Natural Sciences and Humanities in Siedlce, Poland. The examined factors included: I – three morphotypes of winter rape: population cultivar (Monolit), hybrid semi-dwarf (PR44D06) cultivar, restored hybrid cultivar of conventional growth type (PT205); II – two sowing methods: row spacing of 22.5 cm, row spacing of 45.0 cm; III – four types of applied biostimulators: control variant (without application of biostimulators), Tytanit® biostimulator, Asahi®SL biostimulator and Silvit® biostimulator. The aim of the research was to determine the effect of natural plant preparation on the yield of four cultivars of winter rape. It was found that biostimulators applied in the experiments increased the thousand-seed weight on average from 0.03 to 0.1 g in comparison to the control variant. The highest value of this feature was obtained in the variant with Asahi®SL treatment and significantly lower in plots treated with Silvit® and Tytanit® bioregulators. A significant increase in seed yielding was observed as the effect of natural growth stimulators. The highest value of this feature was observed in all cultivars after the application of Asahi®SL and Silvit®.
