In this study the effect of different regions and different NPK treatments on the content of protein and S were investigated in the kernels of winter wheat (Triticum aestivum L.). Plant samples were collected from five experimental stations of the Hungarian National Long-term Fertilization trials. These stations are as follows: Bicsérd, Iregszemcse, Karcag, Nagyhörcsök and Putnok. These experimental fields have different types of soil and climatic conditions. The sulphur content of samples was measured using inductively coupled plasma optical emission spectrometer (ICP-OES) followed by digestion with HNO3-H2O2 solution. The protein content was determined using Khjeldal method. Data analysis was done using SPSS for Windows 13.0 Software package. All data were subjected to ANOVA method, but after detection of significant differences (P<0.05) data were subjected to Duncan’s test to allow separation of means. During our investigations it was proved that different growing places are having significant (P<0.01) difference in the S and protein content of samples. Sulphur and protein content of the treated samples were found higher than the element content of the untreated grains.
