This study aimed to evaluate the effect of two soil management approaches: plowing and harrowing (AG) and plowing and harrowing with sub-soiling (AGS) on wood productivity of two Eucalyptus hybrids, in the Chapada do Araripe, Pernambuco. Sub-soiling was done down to 40 cm deep in the row for two hybrids: Eucalyptus grandis x E. camaldulensis (EGC) and E. brassiana x E. urophylla (Ebu), planted in with a spacing of 3.0 x 3.0m. The experimental design was a randomized block with four treatments and eight replications. At six years old, the height, diameter at breast height, survival (number of plants in relation to the initial stand), and timber production per plant were measured. The survival of hybrids in different soil preparations varied from 95 to 99%, and provided no significant difference between treatments. The hybrid Ebu planted in soil under plowing and harrowing showed significantly lower values for height (10.6 cm), timber volume (99 m3.ha-1), and IMA (16.5 m3.ha-1.year-1), compared to the other treatments. Additional parameters were obtained: mean annual increments AG-EGC = 27.0 m3.ha-1.year-1, AG-Ebu = 16.5 m3.ha-1.year-1, AGS-EGC = 24.6 m3.ha-1.year-1, AGS-Ebu = 23.7 m3.ha-1.year-1. The hybrid EGC performed better for both treatments analyzed in relation to the hybrid Ebu. |
