The article is a review work, periodic moistening - a layer of water is absent throughout the entire growing season of rice, optimum soil moisture is created through periodic irrigation. Mostly applied permanent and shortened flooding. The most promising is the water regime with shortened flooding. Depending on the method of sowing, debris from the rice field by grasslands and soil salinization, there are various options for this mode. Rice plant, like any other, imposes different requirements for water in different phases of the growing season. The best medium for rice in the period of germination and in the phase of emergence is a moist soil. To obtain seedlings on highly saline soils with a close level of saline groundwater, the most favorable is a small layer of water, which is periodically replaced.

Red rice is classified as specialty rice due to its coloured grain. Red colour that surrounded the outer layer of pericarp showed the existence of anthocyanin in red rice grain. However, heavy metal like arsenic in red rice plant become major concern in human health especially so in babies. This is because red rice normally used as a key raw material in the manufacture of infant cereals. In order to overcome this problem, study on effects of water regime on arsenic concentration in local red rice, MRM 16 was conducted during main season 2007/2008 and off season 2008. The water regimes tested were fully flooded, semi-aerobic and aerobic soil conditions. Result showed that arsenic concentration in the soil and grain was markedly highest when MRM 16 was cultivated under fully flooded in both seasons. However, concentration of arsenic in the soil and grain samples was the lower when the red rice was cultivated under semi-aerobic and aerobic soil conditions. Arsenic concentration in the soil and grain samples showed positive relationship. However, analysis of grain yield showed that the yield performance of MRM 16 was better when the soil was fully flooded or maintained semi-aerobically.
