Effect of Seedling Height and Diameter of Nursery Stock of Ban Oak on Out Planting Survival

A study was conducted to determine the effect of seedling height and diameter of polybag and bare root nursery stock of Ban Oak on survival after out planting. The graded nursery stock of Ban Oak based on morphological parameters (height and collar diameter) was out planted during 2008 and 2009 rainy season in the field. Ban Oak stock raised in polybags performed better in lower limits/elevation of occurrence of this species as compared to bare root stock. However, bare root stock performed equally well in upper limits of occurrence of this species. In good sites, stock height >9” was found to be good indicator of field performance of Ban Oak nursery stock. In stress sites, stock height >18” was found as better parameter related to survival of the seedlings
