Resumo
O uso do plantio direto, associado ao sistema de integração lavoura-pecuária, é uma alternativa de manejo que promove o acúmulo de massa seca no solo, fato imprescindível para tornar o sistema sustentável e lucrativo. O trabalho teve por objetivo avaliar o desempenho operacional do conjunto trator-semeadora sobre palhadas de milho consorciado com urochloas, em diferentes modalidades de semeadura. A cultura da soja foi semeada sobre o consórcio de duas espécies forrageiras (Urochloa brizantha e Urochloa ruzizienses), em cinco sistemas de cultivo: milho com Urochloa na linha de semeadura do milho, misturados ao adubo de base e depositados a 0,10 m (MBL); milho com Urochloa semeados na entrelinha, no mesmo dia da semeadura do milho (MBE); Urochloa na entrelinha do milho semeada junto ao adubo de cobertura no estádio V4 (MBC); milho com Urochloa semeados a lanço no estádio V4 (MBLA) e milho solteiro (Testemunha). Foram avaliadas as variáveis: massa seca da palha do milho, massa seca das forrageiras e massa seca total de palha; e para os parâmetros operacionais: a velocidade de semeadura, patinagem dos rodados, força de tração e potência média na barra de tração. A quantidade de palha produzida pelo consórcio de milho com urochloas interfere no desempenho operacional do conjunto trator-semeadora na operação de semeadura da soja, ou seja, áreas com maior quantidade de palha promoveram maior demanda energética, assim como maior patinagem dos rodados.
The use of no tillage system associated with the crop-livestock integration is an alternate managing that promotes the accumulation of dry matter in the soil, an essential fact to make the system sustainable and profitable. The aim of this study was to evaluate the operational performance of a planter-tractor set on maize straws intercropped with Urochloa, in different seeding modes. The soybean crop was seed on the intercropping of two forage species (Urochloa brizantha and Urochloa ruziziensis) in five cropping systems: MBL (Maize with Urochloa in the maize seeding row, mixed with base fertilizer and deposited at 0.10 m), MBE (Maize with Urochloa seeded between rows at the same day of seeding maize), MBC (Urochloa between rows of maize seeded with the covering fertilizer at the V4 stage), MBLA (Maize with Urochloa by broadcast seeding at the V4 stage ) and MS (Single Maize: control). The following variables were evaluated: dry mass of maize straw, dry mass of forages and total dry mass of straw; and for the operational parameters the speed of seeding, wheel slippage, traction force and average power at the drawbar. The results showed that the amount of straw produced by maize intercropping with Urochloa, interferes in the operational performance of the tractor-planter at the operation of soybean seeding, i.e., areas with higher amount of straw promote greater energy demand, as well as higher wheel slippage.
