Growth response of Heritiera simplicifolia (Mast.) kosterm. and Scaphium macropodum (Miq.) Beumée ex Heyne due to abiotic factors in the nursery

In the earliest stage of development, non-dipterocarp wildlings require specific environmental conditions; they are only able to acclimate to harsher environmental conditions after this stage. As such, the environment acts as a limiting factor of early-stage development in non-dipterocarp shade-tole...

Subsoil supplemented with vermicompost improved wildling growth more consistently than subsoil supplemented with compost or burned mesocarp. The wildling’s height relative growth rate (HRGR) and survival were affected by all treatments.
