Abstract
The growth performance of new stands of Dendrocalamus asper and Gigantochloa levis on marginal lands and fertilized with three organic fertilizers was assessed over a period of 4 years. The experimental site was in the UP Laguna-Quezon Land Grant in Real, Quezon, Philippines. The results have shown a very high survival (100%) rate and comparatively good growth and development of both species. The influence of the organic fertilizers on average number of shoot emergents, number of culms per clump, average height and culm diameter was only significant during the first year of plantation establishment. It is concluded that no statistically significant and consistent improvement in establishment of the clumps or growth and quality of the culms could be assigned to the effects of the organic fertilizers studied over the first four years of plantation establishment at this site.
