Injuries on Seedlings Caused by Potential Weed in Tropical Rain Forest Regeneration Areas
The experiment aimed to assess the injuries on Shorea seedlings caused by weed in artificial regeneration of tropical rain forest in Jambi. Four planting systems, strip nurse planting (using Acacia mangium, Paraserianthes falcataria and Gmelina arborea), line planting, gap planting and natural regen...

Light canopy nurse tree such as P. falcataria failed to suppress ground weed, but in the contrary, A. mangium with heavy canopy still allowed creepers and vines to grow.https://jurnal.ugm.ac.id/jpti/article/view/12393 |
