Growth of Eucalyptus urophylla S.T. Blake Provenances at Gede, Kenya

Abstract

Seven provenances of Eucalyptus urophyl!a from Indonesia and East Timor were established in a trial at Gede along the Kenya Coast. After ten years of growth, the Mt. Wuko Fores and Mt. Boleng provenances from Indonesia proved to be superior to the others. The provenance from Mt. Wuko Fores, Indonesia showed the fastest growth at 25 m in height and 17.2 cm in diameter at breast height (DBH), although general performance of the provenance was variable. Mt. Boleng, Mt. Lewotobi and Mt. Langkoeroe provenances also showed relatively good growth of 24.7 m, 24.3 m and 24.2 m in height and 15.3 cm, 14.7 cm, 17.1 cm in DBH respectively. The over bark volume for Mt. Wuko Fores, Mt. Boleng, Mt. Lewotobi and Mt. Langkoeroe provenances were 550m3, 425m3, 400m3 and 525m3 respectively and survival percent was 76%,88%,85% and 73% respectively. The Mt. Wuko Fores provenance is recommended for growing in Gede along the Kenya coast.
