Abstract
The experiments of water culture were carried out to clarify the effects of organic matters eluted from coconut palm chips on the growth in water spinach. The processed chips for reducing tannin added the circulated water (coconut palm plot: C), and the comparative plot of water (W) set against C. Plant height, stem diameter , fresh stem weight and fresh top weight in C were larger than that of W. The leaf area per plant was 3 times larger and specifi c leaf area was also 2 times larger than that of W. On the other hand, there was no signifi cant difference in SPAD as the index of chlorophyll contents and quantum yield of PS II in chloroplast, respectively. The results suggested that coconut palm chips had the particular growth promoting effect.
