Abstract

Although coir dust is recommended in the current potting mixture for
raising coconut seedlings in polybags, it is becoming a scarce resource even
within the coconut triangle. Therefore it was considered imperative to test
the suitability of other options available locally.
An experiment conducted at the Bandirippuwa Research Nursery of
the Coconut Research Institute revealed that saw dust, paddy husk, decomposed
straw and weed trash were similar in action to coir dust in the potting
media, considering the growth parameters of seedlings. However, with due
respect to practical considerations, saw dust was found to be the best alternative.
If there is no labour shortage, partially decomposed straw and weed
trash can be used. Paddy husk was found to be the least important.
