Abstract
Semi-hard wood cuttings of Carissa grandiflora planted at 15 April 2005 on river sand media, half of them were proposed to magnetic field 0.3 × 10-3 Tesla at the base of cutting for 30 second and other cuttings did not, each group divided into two halves, one irrigated by usual water ( non - magnetic water ) and the other irrigated with
magnetic water (which gained by passing the water through magnetron unit with 2.5cm diameter with magnetic field 0.3 × 10-3 Tesla), the results showed that there were no significant differences between cutting treated with magnetic field and did not for all character studied. On the other hand, cutting irrigated with magnetic water gave the best results of rooting percentage 86.6% and highest roots number / cutting 12.6 root for cutting after 10 weeks from planting date, when compared with cuttings irrigated with non-magnetic water which gave rooting percentage 68.3% and roots number/cutting 11.1 root per cutting, and results show that magnetic cuttings which irrigated by magnetic water caused significant increase in rooting percentage 90% after 3 weeks from planting date when compared with 56.6% to the cuttings not proposed to magnetic field which irrigated with non-magnetic water. Highest rooting percentage 93.3% occur after ten weeks from planting magnetic cuttings which irrigated with magnetic water and that cuttings had significant effect when compared with cuttings didn't proposed to magnetic field and did irrigated with non-magnetic water and their rooting percentage is 73.3%.
