Crop-livestock-forest systems are a sustainable production
alternative based on the integration of several components and
configurations that increase the complexity of management and soil-
plant relationships. The aim of this study was to investigate the spatial
distribution of many agronomic characteristics of maize intercropped
with grass (Urochloa brizantha 'Xaraés') in an integrated crop-livestock
and crop-livestock-forest system. To assess the yield components of
maize intercropped with grass, 120 plant samples were collected in a
normal 30 x 30 m grid at 120 positions. The GeoR software was used to
perform for geostatistical and Kriging analyses. There were found
spatial dependencies in ear insertion height, number of kernels per row,
number of kernel rows per ear, ear length, and ear diameter. In the crop-
livestock-forest systems, we detected geographical variation in corn
plant characteristics, although with a weak spatial relationship. The
observed wavy pattern illustrates the sensitivity of corn characteristics
to the presence of eucalyptus trees. To increase maize yield components
in crop-livestock-forest systems in the southwestern region of the
Amazon, 42-meter-wide tree strips are suggested
