| Abstract:
Eight months old seedlings of Eucalyptus torquata and E. angulosa received three levels of N (0, 200 and 400 kg ammonium sulphate per feddan (4200 m2) at three months intervals. Increasing N level from 200 to 400 kg/fed significantly increased the height of trees of both species. The high level of N (400 kg/fed) gave the highest number of branches. The two levels of N (200 and 400 kg/fed) greatly increased the percentage of essential oil of both species over the central. N at 200 kg/fed gave the highest percentage of cineole. Whereas, N at 400 kg/fed, greath, increased the percentage of citronellol of E. torquata and E. angulosa oils. | |
