ABSTRACT:
The field experiment was conducted in the years of 2013-2016 at the Agricultural Experimental Station – Zawady belonging to the University of Natural Sciences and Humanities in Siedlce. The experiment was set in the split-split-plot system in three repetitions. The studied factors were: I – three varieties of oilseed rape: Monolit (population variety), PR 44D06 (hybrid restored variety with a semi-dwarf growth type), PT 205 (hybrid restored variety with a traditional growth type). II - two ways of sowing: 22.5 cm spacing (row sowing – density of sowing 60 seeds per 1 m-2), 45.0 cm spacing (point sowing – density of sowing 40 seeds per 1 m-2). III – four types of bio-stimulators used: the control object (without the use of bio-stimulators), Tytanit® bio-stimulator, Asahi®SL bio-stimulator, Silvit® bio-stimulator. The aim of the study was to determine the impact of the types of used bio-stimulators and the way of sowing on the fresh and dry mass of plants (rosette, root) of three varieties of winter oilseed rape. The fresh and dry mass of the aboveground part of rosette and the fresh and dry mass of the root system depended significantly on the genetic factor, types of used bio-stimulators and atmospheric conditions prevailing in the individual years of research. From the cultivated varieties, the largest fresh and dry mass of the aboveground part of 1 rosette (on average of 33.3 g and 6.34 g) and the fresh and dry mass of the root system of 1 plant (an average of 7.97 g and 2.30 g) characterised the population morphotype - Monolit. Types of the bio-stimulators used significantly impact the increased values of these characteristics. The greatest fresh and dry mass of plants (rosette, root) was noted on object 3, on which the Asahi SL bio-stimulator was used.
