The aim of the study was to assess the effects of hybrids and planting dates as well as their interaction on oil yield in sunflower forthree-year experiment (2005, 2006, 2007). Three sunflower hybrids (Miro, Rimi and Pobednik) and eight planting dates were included in the experiment. AMMI (Additive Main Effects and Multiplicative Interaction) analysis is one of the mainly used multiplicative models, which evaluates main effects and also interaction. The interaction was detected by using AMMI1 biplot.
