Resumo: The objective of this work was to analyze the spatial variability of soil physical attributes in integrated production systems and its relationship with the growth and yield of a corn (Zea mays) crop intercropped with palisade grass (Urochloa brizantha). The experiment was carried out in an integrated crop-livestock (ICL) system and in an integrated crop-livestock-forestry (ICLF) system, in a Plinthic Hapludox. The ICLF system was managed in alleys between eucalyptus (Eucalyptus spp.) rows, spaced at 18, 30, and 42 m. Corn grain and forage yields were positively correlated with soil clay and moisture contents, whereas grain yield was negatively correlated with soil penetration resistance. The lowest corn plant heights and grain yields were observed near eucalyptus rows. The average values for soil penetration resistance were below 2.0 MPa. Spatial variability was verified for: corn plant height, grain yield, and agronomic efficiency; forage intercropping; and soil moisture and silt contents, as well as penetration resistance. Greater grain and biomass yields were obtained at a 42-m distance between tree rows. The obtained results are indicative that corn traits and soil physical attributes were only slightly associated. The spatial distribution of the eucalyptus rows influences the agronomic efficiency of the intercrop and soil moisture contents.

O experimento foi conduzido em sistema de integração lavoura-pecuária (ILP) e em sistema de integração lavoura-pecuária-floresta (ILPF), em Latossolo Vermelho-Amarelo distrófico plintossólico. O sistema de ILPF foi manejado em aleias, com renques de eucaliptos (Eucalyptus spp.) espaçados a 18, 30 e 42 m. As produtividades de grãos de milho e de forragem se correlacionaram positivamente com os conteúdos de argila e de água no solo, enquanto a produtividade de grãos se correlacionou negativamente com a resistência do solo à penetração. As menores alturas de plantas e produtividade de grãos de milho foram observadas próximo aos renques de eucalipto. Os valores médios de resistência à penetração estiveram abaixo de 2,0 MPa. Verificou-se variabilidade espacial para: altura de plantas, produtividade de grãos e eficiência relativa do milho; consórcio com foragem; e conteúdo de água e silte no solo, bem como resistência do solo à penetração. As maiores produtividades de grãos e de biomassa foram obtidas à distância de 42 m entre os renques. Os resultados obtidos são indicativos de que os caracteres do milho estiveram apenas levemente associados aos atributos físicos do solo. A distribuição espacial dos renques de eucalipto influencia a eficiência relativa do consócio e a umidade do solo.Empresa Brasileira de Pesquisa Agropecuária - EMBRAPA2020-05-14T19:00:54Z2020-05-14T19:00:54Z2019info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFEITOSA, I. de L. et al.
