The research was conducted during 2011 - 2014 in the experimental field of the Department of Plant Production in Agriculture Faculty at Trakia University, Stara Zagora, Bulgaria. In this study has examined the nutritional value of two common wheat: Diamond (by the varietal list of Bulgaria) and Bologna (Syngenta). Comparative analysis of grain varieties and options of treatment of crops with some herbicides and herbicidal compositions and was made. The results of these variants were analyzed: 1. Control - no treatment; 2. Axial one - 1000 ml/ha; 3. Lintur +Traksos 150 g/ha+1200 ml/ha - a tank mix; 4. Logran+Traksos 37.5 g/ha +1200 ml/ha - a tank mix; 5. Lintur +Axial 150 g/ha+900 ml/ha - tank mixture and 6. Logran +Axial 37.5 g/ha+900 ml/ha - tank mixture. At the varieties Diamond and Bologna has been found that after treatment with the herbicides content of the crude protein for the period of the field study is moving in the range of 153.5 - 169.4 g/kg DM variety Diamant and from 156.9 to 158.7 g/kg DM for variety Bologna. Products for weed control does not significantly affect the content of FUG and FUM in two varieties of grain wheat. Analysis of regressions showed high positive correlation between PDI and CP in two varieties (r = 0.94-0.99) for the entire study period. Significantly higher the correlation between FUG and DEE. Data analysis for the content of intestinal digestible protein (PDI) show that the herbicide does not affect the levels of PDI in the grain.
