This work evaluated the performance of clonal olive tree gardens in successive cuts aiming cutting propagation. The clonal garden was installed in March 2006, in grooves 40 cm deep. Two cultivars (Ascolano 315 and Arbequina) were evaluated and cut in 2007, 2008 and 2009. The test was carried out in split plot in time in a randomized block design with fi ve replications. The plots were composed of three lines, one meter spaced between them, three plants in each line, spaced 0,5 m from each other, totaling nine plants per plot, being evaluated only the three most vigorous plants. For evaluation, three plants were pruned 20 cm height above soil, after 12 months of cultivation, it was evaluated the yield of cuttings with four knots and two pairs of leaves; plants height (m), torso diameter the 20 cm height of the soil (cm); branches length (m); and total green mass accumulated (kg). In most features evaluated, the best results were observed in the ‘Ascolano 315’. The successive cuts may be extended over a three year period. The parameter estimates indicate that plants of both cultivars y responded satisfactorily to regrowth.
