| Abstract : | The objective of the study was to estimate the influence of fertilisation with ash from conifers biomass and sewage sludge on the content of selected nutrients in tubers of Jerusalem artichoke (Helianthus tuberosus L.). The field experiment was conducted in Ujkowice near Przemyśl. The first factor was four levels of fertilisation with ash of coniferous biomass: 0 – control treatment, without fertilisation; I – 15 kg; II – 30 kg; III – 45 kg on a plot of 35 m2. The second factor was two levels of sewage sludge fertilisation: 0 – control treatment, without sewage sludge; 30.3 t ha–1. The third factor was Jerusalem artichoke cultivars: ‘Gigant’ and ‘Albik’. In samples of tubers from two consecutive harvest years (2015, 2016) the content of dry matter, crude protein and crude ash were studied. It was found that with increasing dose of ash from biomass there was a significant increase of dry matter, crude protein and crude ash content in tubers of Jerusalem artichoke. Fertilisation with sewage sludge significantly reduced the concentration of dry matter and crude protein in studied tubers. The tubers harvested from plots fertilized with sewage sludge had distinctly more crude ash. Tubers of cv. ‘Gigant’ were characterised by better chemical composition. |
