Experiment was conducted at the University Farm, Faculty of Agriculture, Khon Kaen University from March to December 1997 with the aim of studying the effect of soil water regimes on growth and rhizome development of Curcuma alismatifolia. A Randomized Complete Block design with four replications was used in the study. The three water regimes (W1-W3) imposed on the crop using the line source sprinkler. W1 was the amount of water that the crop received at the distance 0-5 m from the source and was considered to meet the demand of the crop. W2 and W3 were the amount of water which less than W1 and W2 respectively. It was found that the Curcuma received the highest amount of water had the shortest duration of days to emerge and days to first flowering (51 and 70 days, respectively), whereas the Curcuma that received the lowest amount of water had the longest duration of days to emerge (56 days) and days to first flowering (83 days). It was also found that the highest rhizome number (13 rhizome/hill), total rhizome (210,269 rhizome/rai) and rhizome weight (7,370 kg/rai) were obtained from the Curcuma that received the highest amount of water. The lowest rhizome number (10 rhizome/hill) total rhizome (153,185 rhizome/rai) and rhizome weight (5,642 kg/rai) were obtained from the Curcuma that received the lowest amount of water.
