Response of sorghum on nitrogen and sulphur fertilization

Sorghum is suitable crop for semi-arid regions with limited irrigation capacity or dry land with unpredictable rainfall. The combination of rising temperature and change of rainfall distribution during the year makes some localities of Czech Republic right place for sorghum cultivation. Sufficient nitrogen and sulphur nutrition is important for sorghum growth and yield. The aim of this study was to compare the effect of common fertilizers and fertilizers with nitrification and urease inhibitors on sorghum biomass yield in condition of Zabcice. In precise small-plot experiment was used these fertilizers: Urea and DASA which represented common fertilizers, Alzon neo-N, Urea(stabil) and Ensin which represented fertilizers with inhibitors. Variant with DASA and Ensin, which contain nitrogen and sulphur, had higher biomass yield than variant fertilized by Urea and Urea(stabil). The highest biomass yield was found on variant Alzon neo-N (28.47 t/ha). Nevertheless, all variants with fertilizers with inhibitors had slightly higher biomass yield than variants with common used fertilizers without inhibitors.
