This study was undertaken at the nursery of the Department of Horticulture, Faculty of Agriculture-University of Khartoum during Autumn, Winter and Summer seasons 2004-2005. The objective of this study was to determine rooting ability of cuttings of pomegranate in response to: a) position of cutting in the branch b) treatments with different concentration of IBA rooting-hormone. To achieve the objectives of the study, the same experiment was carried out at the three seasons: Autumn, Winter and Summer. Cuttings from basal, medium and terminal part of branch from pomegranate were prepared and planted in sand soil under lath house 50% shading, Indole Butyric Acid (IBA) at zero, 2000, 4000 and 6000ppm were used. Results showed that basal cuttings were the best among seasons in terms of number of roots and roots length followed by medium cuttings then terminal cuttings. The highest number of roots resulted from 4000ppm IBA followed by 6000ppm IBA then 2000ppm IBA, respectively in regardless of seasons. The highest percentage of established cuttings (95%) was reported in Summer season followed by (55%) in Autumn season, then complete failure of rooting in Winter season
