abstract:
The aim of the research was an assessment of mineral fertilisers, pig manure and municipal sewage sludge fertilisation effect on the yield and some quality indices in spring wheat grain. The investiga-tions were conducted for three years as a field experiment. Apart from grain dry matter yield and a thousand grain weight, total nitrogen, protein and sulphur contents were assessed as well as contents of cysteine, methionine and lysine were determined in the investigations. The research demonstrated a lesser effect of fertilisation with sewage sludge from a biological treatment plant and manure on wheat grain yield, whereas fertilisation with the sludge from a mechanical-biological treatment plant allowed to obtain a significantly larger yield, comparable with the amount of grain which was produced on the treatment receiving exclusively mineral fertilisers. The wheat grain from treatments where sewage sludge from the mechanical-biological treatment plant was used was significantly better filled. No noteworthy differences in nitrogen or sulphur content were assessed in wheat grain fertilised with phosphorus and potassium applied as mineral fertilisers or in this element content in wheat grain from treatments where manure or municipal sewage sludge were used for fertilisation. Application of sewage sludge in moderate doses, according to plant requirements for nutrients, did not lead to worsening of yield biological value.
