SUMMARY: The aim of this investigation concerning the alder growing in the mixed plantations is to determine the effects of alder-fixed N on the growth of various white willow clones and the selection of genotypes with the best ability of alder-fixed N conversion. It is also important to establish the overall ef fects of the black alder on the soil and the weed vegetation and to determinate the extent to which alders affect the survival and the production of willow growing in association with them in mixed plantations. The experiment involving the plantation of white willow clones with black alder covers an area of 8.66 ha in the northwestern part of Croatia, in Kloštar Podravski. It was set up in the spring of 1980 with white willow clones, aged 1/2, and black alder, aged 1+1, on the peat-clay soil. The white willow plants were planted at a4x4m spacing. In this experiment the white willow was represented by 24 clones, of which 12 were planted without the black alder as a control plot. At the plantation age of 8, the white willow and the black alder were felled in portions of the experiment, and after the felling the following test plots were formed. Plot 1 - Salix alba, 12 clones Plot 2 - Salix alba, 24 clones with Alnus glutinosa Plot 3 - Salix alba, 24 clones, A. glutinosa felled Plot 4 - A. glutinosa, S. alba felled Up to the plantation age 8, the experiment involving 24 (respectively 12) white willow clones, was designed as a randomized block in 4 replications, with 25 plants per small plot. Black alder was represented by plants of local provenance. The experiment of the white willow selected clone growing in the mixed culture with the black alder showed that, with the planting spacings of 4 x 4 m and 4x1 m for the white willow and the black alder respectively, the influence of the black alder on the white willow clone production is neglectable during the first five years of plantations age.
