          Abstract

          O presente estudo foi realizado no município de Atibaia, maior produtor de morangos do Estado de São Paulo, com o objetivo de avaliar a profundidade efetiva do sistema radicular do morangueiro em diferentes níveis de água e coberturas do solo. O experimento foi instalado em esquema fatorial 2 x 2 (coberturas do solo e níveis de água). Como coberturas do solo foram utilizados os plásticos transparente e preto. As irrigações foram realizadas sempre que o potencial de água no solo atingia -0,010 e -0,070 MPa, a 10 cm de profundidade. As amostragens de raiz foram realizadas ao lado da planta, de 10 em 10 cm até 60 cm de profundidade, com trado tipo caneca com 7 cm de diâmetro, aos 159 dias após o plantio, com cinco repetições. Os resultados obtidos em comprimento de raiz (cm) por unidade de volume do solo (cm³) indicam maior concentração de raízes nas camadas superficiais. As coberturas do solo e níveis de água não influenciaram no comprimento de raízes nas faixas de profundidade do solo avaliadas. Para fins de irrigação, a profundidade efetiva do sistema radicular foi de 30 cm.

          The present work was carried out in Atibaia, the major site of strawberry production in the state of São Paulo, Brazil. The aim of this work was to evaluate the root effective depth of the strawberry crop under different water levels and soil covers. The experiment was conducted using a factorial scheme 2x2 (soil covers and water levels). As soil covers a clear plastic and a black plastic were used. Irrigation was applied until the soil water potential reached -0.010 and -0.070 MPa, at 10 cm depth. The root samples were collected beside the plants each 10 cm, up to 60 cm depth, using an auger hole with 7 cm of diameter, 159 days after planting, with five replications. The results concerning root length per unit of volume showed that the roots are concentrated in the upper langers. Soil covers and water levels did not influence the root length distribution. For irrigation purposes the effective strawberry root depth is 30 cm.
