Demanda energética por semeadora-adubadora em função da haste sulcadora na semeadura do milho

Abstract: Energy demand of a planter as a function of the furrow opener in corn sowingThe 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 … Show more

“…Contudo, foi evidenciada influência significativa sobre a demanda entre estes grupos, sendo que o primeiro foi o que exigiu menor força, apresentando diferença de 17,32%. Este fato foi comprovado por FURLANI et al (2013), avaliando a demanda de tração de uma semeadora em diferentes velocidades.…”

“…Studies developed in Paraná affirm that around 45% of farm areas with clayey soil and cultivated with soybean/corn show levels of compaction in the 0.1 -0.2m layer, which is restrictive to root and aerial development of the plants (Franchini et al, 2011). Consequently, most farmers use shank-type furrow openers to prepare the soil and unpack the topsoil (Furlani et al, 2013). However, use of the chisel rod-like opener, or furrow opener, has become commonplace, even in areas where high levels of soil compaction are not observed.…”
