Morphophysiological characteristics of oilseed rape flowers, such as features of the nectaries, nectar production, and observations on honey bee visits and honey and seed yield were studied with the aim to evaluate the melliferous potential of this crop as well as its attractiveness to pollinators. Calculation of the theoretical maximal honey yield revealed that the actual amount of extracted honey was much lower than the potential yield, indicating that this bee pasture is underutilized. We found that honey bee pollination increased oilseed rape yield, i.e., seed production, by 12 % compared with the treatment in which pollinators were excluded.
