Abstract

Semi hardwood cutting colleted in the medium portion of the Ascolano 315 and Arbequina olive cultivars were prepared with 12 cm of length and four leaves, and treated with of IBA (3,000 mg L-1) by five seconds. The experiment was carried out in a greenhouse equipped with a mist nebulization system. Using a randomized experimental design in factorial scheme, in 4 replication, were tested the two cultivars and six fertilizers (Biofertilizante, Nippoterra, Fert Bokashi, Ativo, in the proportion of 25 mL L-1, Nutricafé and Rocksil, in the proportion of 25 g L-1) plus a control without fertilization. The products were applied in the trays contends perlite as substrate, in a unique dosage, defore cutting. After 67 days, the percentage of cutting with callus, rooted, number and lengh of rootses were evaluated. The Biofertilizante showed best results, in comparison to the other fertilizers, and the Ascolano 315 olive tree cultivar it presented best roots indexes.
