Zusammenfassung

Mixed plantations are presented as an alternative aimed at improving the productive-economic-environmental balance through an optimal compartmentalization of the habitat with combinations of complementary species. We evaluated three walnut plantations for wood with hazelnut accompaniment in Caldes de Montbui (Barcelona, 8 years old), Prades (Tarragona, 9 years old) and Ontinar de Salz (Huesca, 10 years old). The classic mono-specific walnut system is compared to a 6x6 m and 7x7 m frame, compared to a system with the same frame but with the accompaniment of two hazel bushes on both sides, at a distance between 0.75-1.50 m. We established records of primary and secondary growth, amount and type of branching and conformation of the walnut tree to a height of 3.0 ± 0.5 m. In the hazelnut, the crown diameter was measured and fruit production was estimated. The accompanying treatment resulted in more straight and less elliptical walnut stems, with fewer branches and knots. The conclusion indicates that the control of the distance between both species and the choice of a vigorous material of hazelnut, of growth measured with the walnut, can favor a production of wood of higher quality and a reduction of the effort of pruning. Furthermore, with the production of hazelnut, an annual economic return is introduced with respect to monospecific plantations, provided that the higher water demand of the system can be compensated.
