Abstract

Potting mixtures containing different proportions of river sand were used for
raising coconut seedlings' in polybags with and without fertilizer, to evaluate their
growth and vigour after seed nuts were allowed to germinate on a pre • nursery bed
and then transplanted. The substitution of topsoil in the pplybag mixtures with river
sand had no significant effect on the development of coconut seedlings. It was found
that pure river sand alone could be successfully used, provided seedlings were kept
free from water deficit and in this respect the first seven months from seed nut
laying was found to be critical.
Application of fertilizer improved the seedling height and girth but this effect was
significant only five months after seed nut laying. However, in this study the
improvement in seedling vigour was inadequate to justify the extra input on
fertilizer.
