Dwarf coconut seedlings were raised in polybags under four mulching treatments (no mulch, coconut husk, oil palm bunch refuse and grass) and two weeding regimes (designated Wo and Wl) in the nursery. Weeding was done once every month in Wl plots whilst Wo plots were left unweeded. Weed competition reduced the growth of coconut seedlings a great deal and the unweeded and unmulched plants were not vigorous enough for transplanting. Weeds reduced dry matter yield of leaves, stem and roots in unmulched plots by 61, 46 and 44% respectively. Mulching was beneficial and reduced competitive effects of weeds. Mulching increased plant height, girth and dry matter yield. At harvest, leaves formed the greatest proportion of the dry matter; the mean being 171.6 g compared with 20.8 and 43.2 g for stem and roots respectively. Soil temperatures were only moderately reduced by mulching. Coconut husk suppressed weeds the most but oil palm bunch refuse increased K content of soil more than any other mulch material.
