The sunflower (Helianthus annuus) gives good yields, provided that there is advanced sowing, with limed soil and favorable climatic conditions for the better development and higher yield. To be fertile, the sunflower demands boron, a deficiency of it may limit the yield. This work aimed at evaluating the field interaction between two boron-based commercial products and two sunflower hybrids and the control. This work was conducted in Realeza Municipal District, Paraná State, Brazil, in Udic Dystrophic Oxisol. Treatments consisted of two hybrids of Nidera Company (Paraiso 20 and 33) and two commercial products, the sodium octaborate (20.5%) 9 kg ha-1 and boric acid (18.5%) 10.8 kg ha-1, arranged in randomized blocks in a factorial outline 3 x 2 with four replications. The following parameters were evaluated: plant height, stem diameter, head seed diameter and hundred seed weight and yield. There was no significant difference between the sunflower hybrids. The pre-seeding boron application, regardless the source, positively influences the crop development.
