Field polyfactorial experiments with sunflower (hybrids: NK Brio, Alexandra PR, NK Alego) were realized on the experimental base of Center of Biology and Ecology of Plants FAFR SUA in Nitra Dolná Malanta. Forecrop of sunflower (Helianthus annuus L.) was wheat (Triticum aestivum L.). Experiments were established by method of divided blocks with three replications. Levels of factors were randomly organized. The aim of the experiment was found influence of weather conditions on natural and energetical evaluation of sunflower production. Better continuance of weather conditions, in term of cultivating of sunflower were in the year 2010, when there where reached higher amount of average yield (3.34 t per ha) and gross energy (58.23 GJ per ha) From monitored hybrids was productively best hybrid Alexandra PR, which achieved highest values of achene yield (3.1 t per ha) and gross energy (54.70 GJ per ha) in continuance of whole experimental period.
