INFLUENCE OF TESTED FERTILIZERS ON WINTER OILSEED RAPE YIELD

Abstract

The research was carried out in 2021 at the Vytautas Magnus University Agriculture Academy Experimental station.

Variants of the experiment:

1. Control
2. Amino acid complex (TSC) - 1.0 l ha^-1
3. Potassium fertilizer K-Leaf - 3.0 kg ha^-1
4. Amino Acid Complex (TSC) - 1.0 l ha^-1 + Potassium Fertilizer K-Leaf - 3.0 kg ha^-1
5. Potassium fertilizer K-Leaf - 5.0 kgha^-1
6. Potassium fertilizer K-Leaf– 5.0 kg ha^-1 + Potassium fertilizer K-Leaf - 5.0 kg ha^-1

Research methods: a field experiment was performed in which crop productivity and qualitative parameters were determined by taking samples from at least 5 different locations in the experimental field in a 0,5 m longitudinal row.

Research results: fertilization with the mixture TSC 1.0 l ha^-1+ K - leaf 5.0 kg ha^-1 in most cases – seed yield, seed productivity per plant and seed content in the pod were superior to other fertilization options and controls.
