Description
Summary:The use of chisel type openers in no-till planters has become widespread, mainly in areas with clay soils, as an alternative to break the most compact superficial layer. However, in some conditions the efficiency of the chisel opener is not constant due to characteristics of the soil, sowing and even the tillage system. Thus, the aim of this study is to evaluate the performance concerning the demand of power from five different chisel openers for a no-till planter. The experiment was conducted in the experimental field of the Jumil Company, in the municipality of Batatais, Sao Paulo - Brazil. A planter fertilizer spreader Guerra JM7090PD EX with five planting units was used in the experiment. Corn sowing was carried out on Brachiaria decumbens Stapf straw The parameters analyzed were force and power in the drawbar, speed, operational field capacity and crop yield. The speed, operational field capacity and crop yield were not significantly among the openers and the opener 4 showed less traction demand and power in the drawbar.
