Italia on rootstock IAC-313 irrigated by microsprinklers and by drippers were performed by profile method aided by digital image processing. In trenches with 1m depth and 2m width values of root density (root area / soil area) obtained at five soil profiles (1.0, 0.8, 0.6, 0.4, and 0.2m distance from trunk in a perpendicular direction to plant row) showed that microsprinkler irrigated plants had greater root dispersion than those irrigated by drippers in a yellow red latosol  aBrazil  agrapes  airrigation  aroot systems  aIrrigação  aProcessamento da Informação  aSistema Radicular  aUva  aVitis Vinifera  aDistribuicao  aDistribution  aImagem  aInformation processing  aNordeste  aNortheast1 aJORGE, L.
