Three experiments of associations between forest and agricultural species were installed on Estacoes Experimentais of Assis and Marília. The associations included two Pinus species: Pinus elliottii var. elliottii and Pinus caribaea var. caribaea and three agricultural species: coffee (Coffea arabica), rice (Oryza sativa) and bean (Phaseolus vulgaris) intending to study forest development and the shadiness influence on agricultural species. Generally there is no influence of association on height and diameter growing or on agricultural production. The coffee individual production was the same for all kinds of associations. Rice and bean cultures associated with pine were affected by shadiness. The best association was 133 thousand plants/ha (four rows) between Pinus rows. On rice, coffee and Pinus associations the greatest rice production occurred when coffee was the main cultivation, followed by pine, coffee and rice association.
