EFficacy of Rigenal P and Liqhumis* 18 in Rooting and Vegetative Growth of Olive, Olea Europaea Cuttings
The research was carried out to evaluate the response of three types of cuttings (limb basal, medial and lateral) to individual or combined treatments of rooting agent Rigenal P and LIQHUMUS *18 in pots under greenhouse conditions. There were significant differences between the three olive cutting types. The basal cuttings significantly had higher responses for rooting than the two other types showing the highest 30% rooting, 6.25cm root length, and 1.67cm shoots length. The highest percentage of rooting was in the combined treatment (Rigenal P+LIQHUMUS *18) in basal and medial cuttings followed by basal/Rigenal P and basal/LIQHUMUS *18. Number of roots/cutting was the highest in lateral/LIQHUMUS *18, which did not differ from that of basal/Rigenal P+LIQHUMUS *18. Root length and number of vegetative buds were the highest in basal/Rigenal P+LIQHUMUS *18 followed by the medial in same treatment. Basal cuttings also had the highest vegetative growth and number of leaves/cutting especially in the Rigenal P treatment followed by the combined treatment with medial cuttings.
