GROWTH PERFORMANCE OF EUCALYPTUS GLOBULUS AS INFLUENCED BY STAND AND SITE FACTORS IN CHELELEKA CATCHMENT, CENTRAL ETHIOPIA

This study was conducted on a 4-y-old fuelwood plantation of Eucalyptus globulus in Cheleleka Catchment, central Ethiopia. Using the General Linear Model (GLM), significant effects of stand density (number of survivors/plot) and altitude on mean tree height and mean diameter were found. As stand den...

520			\|a This study was conducted on a 4-y-old fuelwood plantation of Eucalyptus globulus in Cheleleka Catchment, central Ethiopia. Using the General Linear Model (GLM), significant effects of stand density (number of survivors/plot) and altitude on mean tree height and mean diameter were found. As stand density increased, mean tree height and diameter increased. In this study, none of the site factors significandy influenced the number of survivors per plot. The best growth in the catchment was at altitude 2950 m a.s.l. In this topographic position, mean tree height and mean diameter at breast height were greater than those in the valley floor (2850 m a.s.l.) and in the upper parts of the catchment (3050 and 3150 m a.s.l.). Further studies on the influence of site factors on catchment microclimate in relation to tree growth are recommended. Kajian ini dijalankan di ladang kayu api Eucalyptus globulus berumur empat tahun di Cheleleka Catchment, tengah Ethiopia. Menggunakan Model Linear Am (GLM), kesan kepadatan dirian bererti (bilangan pokok yang terselamat/petak) dan altitud bagi ketinggian pokok min dan garis pusat min diperoleh. Apabila kepadatan dirian bertambah, ketinggian pokok min akan bertambah. Dalam kajian ini, dada satupun faktor tapak mempengaruhi dengan bererti bilangan survivor bagi satu petak. Pertumbuhan yang paling baik dalam kawasan tadahan ialah pada altitud 2950 m a.s.l. Dalam kedudukan topografi ini, ketinggian pokok min dan garis pusat aras dada min adaiah lebih tinggi daripada pokok yang terletak di lantai lurah (2850 m a.s.l.). Disyorkan supaya kajian yang lebih mendalam dijalankan mengenai pengaruh faktor tapak terhadap mikrocuaca tadahan yang berkaitan dengan pertumbuhan pokok.
