Plant growth for sea oats (Unlola paniculata, L.) grown in screened and unscreened sewage sludge compost was assessed by comparing plants grown in these 2 materials, and combined with beach sand, with plants grown in 2 commercially available potting mixes which were used as standards. Fifteen individuals each of U. paniculata were grown for 4 months in 25 cm. diameter containers in respective mixtures of screened compost to beach sand of 1:0, 3:1, 1:1, 1:3, (v:v) and unscreened compost in the same ratios for a total of 10 different potting mix combinations, including the 2 standards. Growth was evaluated by means of size index in which plant height and spread were summed. At the end of the growing period 3 potting mixes: Metromix 300R, a 3:1 beach sand:screened compost (v:v) exhibited significantly faster growth and culm production than the other 7 mixes.
