THE INFLUENCE OF FERTILIZING THROUGH THE LEAVES FOR WINTER RAPESEEDS PRODUCTIVITY

Abstract

Research hypothesis: the application of biological preparations increases the productivity of winter rapeseed plants. The aim of the research: to evaluate various biological preparations used in autumn and their effect on the productivity of winter rapeseed.

The object: to determine the influence of biological preparations on the yield of winter rape seeds and the elements of the crop structure.

Biological preparations sprayed in the autumn on the rosette of winter rape in the pot had a positive effect on the productivity of winter rape seeds. The TerraSorb Complex (0.5 l ha^-1) used significantly increased the average seed productivity of the plant, the number of seeds per plant, the weight of 1000 seeds and the maximum weight of seeds per plant. The biological preparation used in the rosette stage of winter rapeseed MillerPlex (0.5 l ha^-1) had a positive effect on the density of the crop and the number of pods on the plant, but there were no significant differences, as the number of pods differed by 12 units from the other variants.

The application of TerraSorb Complex (0.5 l ha^-1) K-leaf (3.0 kg ha^-1) mixture in the spring after winter rape reached the budding stage had the greatest impact on all studied seed productivity indicators.
