The aim of this study was to evaluate the productivity of four varieties of soybean grown under both cross-seeding and conventional systems. The experiment was conducted in Campina da Lagoa, in the state of Paraná, Brazil during the period from October to February 2012/2013 in a completely randomized factorial scheme (4x2) with five replications. Treatments consisted of four soybean varieties: 4990 Nidera RR, VMAX Syngenta RR, BMX MAGNA RR and 5909 Nidera RR, with two planting systems: crossed and uncrossed. The following components of growth and yield were evaluated: Fresh and dry mass, pod number, plant height and yield in kg -1 . Variety VMAX stood out in terms of productivity, regardless of the planting system. The cross-seeding system provided increment of 9.25% in grain yield.
