The present study was carried out to investigate the effect of irrigation intervals on the growth, flowering and chemical constituent of Strelitzia reginae Ait plant. One year old plants were treated with three different irrigation intervals at 10, 20 or 30 days. Irrigation water was added with constant level of 5 cm depth as (200 L/4m2). During a whole year of growing, Water consumptive use (Cu), Crop coefficient (kC), Relative water content (R.W.C.) and Water use efficiency (W.U.E.) were calculated. The growth parameters and flowering characteristics as influenced by water regime were measured. The results of this study showed that, short irrigation interval enhanced vegetative growth as well as inflorescence yield compared to longer intervals. The chlorophyll content, N, P and k percentages in both leaves and inflorescences were gradually decreased with increasing irrigation intervals. The most significant irrigation interval was 10 days followed in most cases by 20 days interval treatment.
