East Nusa Tenggara Province, known as a dry area in Indonesia with sub optimal soil and uncertain climate. Although sorghum (Sorghum bicolor) is known to be suitable plant in this area, the sub optimal soil and the long period of dry season often become constraint for the cultivation. Sorghums still need enough water during their period of life. Research conducted in the green house and in the field in Cibinong indicated that water deficit will affect the physiological characteristics. To develop sorghums suitable for cultivation in the East Nusa Tenggara Province, simulation of water requirement of two types of sorghums with sub optimum soil was conducted. The simulation of crop factor and soil factor resulted that grain sorghum with stages and total life period of 130 days (vegetative, reproductive, maturity and harvesting stage) needs a total of 371 mm of water, and number to irrigate was 5 multiplicated by 58 mm. While sweet sorghum with stages and total life period of 140 days needs a total of 479 mm water, and number to irrigate 12 multiplicated by 40 mm. This simulation was very important in order to develop sorghums that can adapt to lacking of water environment by applying some water use efficiency technique.
