In 2017, three experiments were carried out at Nakheel Palestine farm in Jericho-Palestine to study the effect of Indole Butyric Acid (IBA), some rooting media, and different colors of polyethylene bags on rooting of aerial date palm offshoots.
The experiments consisted of four IBA treatments viz.; T1: control, T2: localized IBA powder, T3: IBAthrough irrigationand T4: T2+T3. In addition to eight rooting media treatments namely M1: control, M2: organic matter, M3: organic matter + soil + sand, M4: organic matter + Tuff, M5: soil +Tuff, M6: sand +Tuff, M7: peat moss +Tuff, and M8: peat moss + vermiculite. As well as eight colors of polyethylene bags viz., control (transparent), white, black, green, red, blue, yellow and brown.
Among IBA treatments used, the treatment T2 significantly influenced almost all the root and shoot parameters of aerial date palm offshoots. While among various rooting media treatments experimented, the treatment M7 was the most effective for almost all the root and shoot parameters. Furthermore, among different colors of polyethylene bags tested, the blue bag was significantly superior in almost all the root and shoot parameters studied in the experiment.
