Abstrakt
The aim of the three-year experiment was to evaluate the action of Starane 250 EC
herbicide and different levels of nitrogen fertilization on the content of ADL and crude ash in the
sward. The field experiment was established on a permanent meadow in April 2007 in śelków in
the system of randomized block with three replications. In the experiment, two research factors
were used. The first experimental factor was varied fertilization (34% ammonium nitrate) in the
amount of A1 – 0 kg · ha–1, A2 – 90 kg · ha–1, A3 – 180 kg · ha–1 and A4 – 270 kg · ha–1. As an
another the research factor was Starane 250 EC herbicide, applied at four concentrations (B1 –
0 dose, B2 – half dose, B3 – 1 dose, B4 – 3/2 dose by the instruction). The results were evaluated
statistically using the analysis of variance for two-factors experiments. The mean differentiation
was verified by Tukey’s test at the significance level p ≤ 0.05. Studies have shown that the
content of both the examined factors in the feed was variable in the years and depended both
on the concentration of Starane 250 EC as well as on the applied nitrogen dose. The best
digestibility, and also the lowest ADL content had the feed from the object where the nitrogen
dose 180 kg · ha–1 and 1/2 Starane 250 th herbicide concentration was used.
