This study was carried out at Tawella, Located north east of Sulaimani, Iraqi Kurdistan Region in order to determine the effect of two budding date (June 5 and June 20) and three concentrations (0, 5 and 10) mg/l-1 of Kinetin on budding   success  and growth scion of black mulberry .Results showed that the highest bud success (60%) was obtained on June 20 compared to 50% for June 5 while 5 mg/l-1 Kinetin gave the highest budding success. Interaction of June 5 and 5 mg/l-1 Kinetin resulted in highest budding success (80%).  Budding on June 5 gave the highest averages of budshoot length and Number of leaves per budshoot. Kinetin at 5mg/l-1 gave highest budshoot length. Interaction June5 and 5mg/l-1 Kinetin gave the highest budshoot length.
