Rapessed (Brassica napus L. var oleífera) is an oilseed, belongs to Brassicaceae family, resultated between inter specific crossing of wild cabbage (Brassica oleracea L.) and mustard (Brassica rapa L., syn. campestris). Boron is considered a micronutrient, acting in sugars translocation, protein formation, pollen tube growth, pollen grain germination, seeds and cell wall development. The objective of this research was to study the interferences in productive components of two rapessed hybrids with application of boron fertilization by leaf application. For this, a field experiment was installed by using experimental design of randomized blocks in a 2 x 3 factorial scheme.  Hyola 433 and Hyola 575CL hybrids and three doses of leaf boron (0; 100 and 200) g ha-1 of B were used. The following characteristics were evaluated: plants number, number of pods per plant, mass of one hundred grains and yield. With boron application there was an increase in grain mass independent of the hybrid. In relation tp grain yield there was increase only for Hyola 433 hybrid, with the highest yield reached at 200 g  ha-1 dose. There was difference in grain yield between hybrids, at 0 g ha-1 dose. Hyola 575 CL hybrid was superior and with boron application, Hyola 433 hybrid showed higher grain yield.
