The objective of this study was to determine the spatial variability of rubber tree dendrometrics characteristics (diameter and height) and its relationship with soil physical attributes (soil penetration resistance and hydraulic conductivity). The experiment was located in Campinas, State of São Paulo, Brazil in a experimental station of the Instituto Agronômico, in a 10 ha area with rubber trees grown since 1992. Samples were taken from 232 points in a grid of 20 x 20 m. The average diameter at the chest height and the height of the trees were determined using the average of four plants. The following soil physical attributes were studied: soil resistance to penetration up to 0.40 m deep and water infiltration in two depths (0-0.10 m and 0.10-0.20 m). All plant and soil variables showed moderate to weak spatial dependence among samples. There was also correlation between spatial variability maps of the rubber tree dendrometric characteristics and the soil physical attributes studied.Key words: geostatistics, plant and soil attributes, Hevea brasiliensis. VARIABILIDADE ESPACIAL DE CARACTERÍSTICAS DENDROMÉTRICAS DE SERINGUEIRA E DE ATRIBUTOS FÍSICOS DO SOLORESUMO: O objetivo deste trabalho foi determinar a variabilidade espacial de características dendrométricas de seringueira (altura e diâmetro das árvores) e sua relação com atributos físicos do solo (resistência do solo à penetração e condutividade hidráulica do solo saturado). O experimento está localizado no Centro Experimental Central do Instituto Agronômico, em uma área de 10 ha cultivada com seringueira desde 1992. As amostragens foram realizadas em 232 pontos com espaçamento regular de 20 x 20 m. As características das plantas de seringueira diâmetro médio na altura do peito e a altura foram determinadas utilizando a média de quatro árvores. Os atributos físicos do solo estudados foram, a resistência do solo à penetração até 40 cm de profundidade e a infiltração de água no solo em duas profundidades (0-0,10 m e 0,1-0,20 m). Todas as variáveis de planta e solo apresentaram dependência espacial moderada a fraca entre as amostras. Também houve correlação entre os mapas de variabilidade espacial das características de plantas de seringueira e dos atributos físicos do solo estudados.Palavras-chave: geoestatística, atributos de planta e solo, Hevea brasiliensis.
