The purpose of this bachelor work is assessment of results the accurate, small plot experiments for sunflower (Helianthus annuus L.). Variety ES Royal and its response after aplication of four different ancillary products (Tomagel HO, Energen Fruktus, Lignohumát B, Unicum Pro). It was observed influence of applicated products for nutrient intakes by flower, change of Habit and mainly for the yield reaction and changes of oil quality. Plant preparations was aplicated in one time in specified quantity in the beginning of extension grow sunflower BBCH30. Plant material sampling for chemical analysis was making before products (BBCH 30) application and later BBCH35. Nutrient content increasing in plant tissues was obvious mainly by nitrogen and the most by variant with using of Energen Fruktus a Unicum products. From microelemnts was significant increasing by manganese for variant Tomagel HO a Lignohumát B. Dry matter of plants was increasing only a litte. The mor by variant Tomagel HO. Auxiliary preparations had not significant influence for increasing of achenes production.The biggest increasing of proceeds (about 2,2%) was by Tomagel HO variant. By all variant was oiliness lower than by control with statistics conclusive difference. For representation each fatty acids do not have applications significant influence.
