Seed emergence under field conditions decisively and directly determines the number of plants per hectare, which is one of three basic components of yield in the plant world. Influence of chemical treatment on field emergence of three commercial sunflower hybrids stored in different conditions was tested in 2007 and 2008 on experimental fi eld of Institute of Field and Vegetable Crops in Novi Sad, Serbia. On average, hybrid H1 had the highest value of field emergence (88.79%) and for chemical treatment fl udioxonil + metalaxyl + imidacloprid (87.71%). Seed kept in common storage had the highest emergence value in fi eld (87.92%). Seed treated with fl udioxonil + metalaxyl + imidacloprid and stored for one year in common storage had the highest fi eld emergence (90.18%). Considering interaction between storage conditions and genotype, hybrid H1 seed sown after chemical treatment had the highest feld emergence (91.82%) and seed kept in common storage (90.48%). Hybrid H1 seed compared with other two had the highest field emergence treated with fludioxonil + metalaxyl + imidacloprid (91.84%).
