Abstract

The objective of this study was to evaluate the production of tropical and winter forage species and soybean production in an integrated crop-livestock system. The following treatments were applied: T1, overseeding of millet + seeding of oat FMS-1; T2, overseeding of millet + direct seeding of oat IPR-126; T3, overseeding of millet + direct seeding of oat IPR-61; T4, overseeding of Tanzania grass (Panicum maximum) + overseeding of Brachiaria ruziziensis; T5, direct seeding of sorghum + Brachiaria ruziziensis. The experimental units consisted of 1.5-ha pastures allocated in a completely randomized design with two replicates. The variables measured were forage production, forage mass, soybean production, and forage residue in direct seeding. In all cuts, forage mass was higher in paddocks with Brachiaria ruziziensis compared to the other treatments, especially Brachiaria ruziziensis with Tanzania grass. The higher forage mass was a consequence of the higher forage production observed in these paddocks. This result shows that tropical grasses could be an alternative to cool-season grasses for winter pasture. On the other hand, no significant difference in soybean production was observed between the strategies used. However, the higher long-term deposition of organic matter in soil resulting from the greater forage mass may contribute to increase productivity. In conclusion, intercropping of Tanzania grass with Brachiaria ruziziensis in integrated crop-livestock systems appears to be an alternative that provides high grain and forage productivity.
