Abstract:


The study was conducted to determine the effect of pollarding on the survival rate and branch development (as to the quantity, length and diameter) of   one-year old Beltik (Syzygium sub-caudatum (Merr.) Merr.) and Dael (Cippadessa baccifera (Roth) Miq.) seedlings. The results are important input in developing management practices to optimize foliage production of the species which are used as tea and medicine locally. The survival rates of Beltik seedlings were not significantly affected by the applied pollarding treatments while that of the Dael seedlings were significantly affected. The seedlings pollarded to retain only 10% of their main stems registered the lowest survival rates in both species. In branch development, the quantity of formed branches is significantly affected but their length and diameter were not significantly affected by the pollarding treatments in Beltik seedlings. In Dael seedlings, it was the average basal branch diameters that were significantly affected.  These results indicate that pollarding near the main stem base or severe pruning can be tolerated by the species but results to higher mortalities, and pollarding or pruning technique that can maintain good growth and form of the species can be developed.
