    Wpływ zróżnicowanego nawożenia azotowego i herbicydu Starane 250 EC na zawartość ADL i popiołu surowego w runi łąkowej

    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.
