Abstract
The response of container-grown rewa-rewas (Knightia excelsa] to five levels of N. P. K and lime were studied. The plants responded strongly to added N with the largest and most green plants receiving 450 to 600g N/m3 while foliage was chlorotic at very low N rates. Phosphorus stimulated foliage growth but there was a linear increase in foliar chlorosis due to iron deficiency. Highest foliar dry matter production occurred with no added lime and pH of 3.5 in the peat: perlite medium, which is typical of a calcifuge.
