Summary:The sustainability of no-tillage system is fully linked to the soil use and management, in order to use technologies that promote the accumulation of dry vegetation in the soil, but it may affect the performance of agricultural machinery. Therefore, the objective of this study was to evaluate in soybean seeding the operational performance of tractor-seeder on maize straws intercropped with Urochloas in different treatments. The study was conducted in a randomized block design in factorial scheme 2 x 4 + 1, with four replications, formed by two intercropped forage species and five cropping systems. The dry maize straw, Urochloas dry mass and total straw dry mass were determined in treatments to verify the operational performance of the machines. The results showed that the amount of straw produced by maize and Urochloas interferes with the slippage of the tractor's front wheels, i.e., areas with higher amount of straw promotes lower adherence of the wheel. Energy demand was not affected by amount of straw produced by the treatments, as well as fuel consumption and operational field capacity. Key words: no tillage system slippage of wheels crop-livestock integration A sustentabilidade do sistema plantio direto esta ligada ao uso e ao manejo do solo com o proposito de utilizar tecnologias que promovam o acumulo de massa seca vegetal no solo porem podem afetar o desempenho das maquinas agricolas. O objetivo deste trabalho foi avaliar, na semeadura da soja, o desempenho operacional do conjunto trator-semeadora sobre palhadas de milho consorciado com Urochloas em diferentes tratamentos. A pesquisa foi instalada em blocos casualizados em esquema fatorial 2 x 4 + 1, com quatro repeticoes, formados pelo consorcio de duas especies forrageiras em cinco sistemas de cultivo. A massa seca de palha do milho, massa seca de Urochloas e massa seca total de palha foi determinada nos tratamentos para verificar o desempenho operacional das maquinas. Os resultados demonstraram que a quantidade de palha produzida pelo consorcio de milho com Urochloas interfere na patinagem dos rodados dianteiros do trator, ou seja, areas com maior quantidade de palha promovem menor aderencia dos rodados. A demanda energetica nao e afetada pela quantidade de palha produzida pelos tratamentos tal como o consumo de combustivel e a capacidade de campo operacional.
