RESUMO.Estudos de manejo do solo na entrelinha da cultura da pupunha ainda são escassos no Brasil. O objetivo deste trabalho foi avaliar os efeitos de diferentes manejos nas entrelinhas da cultura da pupunha em algumas propriedades físicas e químicas de um Latossolo Vermelho distrófico. Os tratamentos utilizados foram os seguintes: controle de plantas daninhas com herbicidas (HB), cobertura morta do solo com bagaço de cana (BC), cultivo alternado de mucuna e de aveia nas entrelinhas da cultura (MA), controle das plantas daninhas com capina manual (CM), controle das plantas daninhas por meio de roçada mecânica (RM) e cultivo de plantas de guandu nas entrelinhas (GD). Foram avaliadas as seguintes propriedades físicas do solo: densidade, porosidade, umidade e resistência do solo à penetração e também as propriedades químicas do solo: pH, Al ABSTRACT. Alterations in physical and chemical properties of a distrofic red latosol under different soil management systems in peach palm (Bactris gasipaes Kunth).Studies aiming to evaluate soil management systems in inter-rows of peach palm are still scarce in Brazil. This work was proposed to evaluate the effects of different soil management systems in peach palm inter rows on chemical and physical properties of a dystrophic Red Latosol. Treatments evaluated included weed control with herbicides (HB); soil covered with sugarcane bagasse (SB); alternate green manures with velvet bean and oats cropping as inter-row crops (VA); inter-row manual weed control (MC); inter-row slashing mechanical weed control (slashing) (MWC) and inter-rows cropping of pigeonpea (PG). The following physical properties of the soil were evaluated: bulk density, porosity, soil water content and soil resistance to root penetration and the chemical properties of the soil: pH, Al , K + and V% were influenced by treatments, with a positive increment in those treatments with specific weed control (HB and MWC), while for P, the treatments HB, MC and MWC stood out positively.
