“…In regions facing water scarcity for paddy rice production, aerobic rice cultivation was well developed because of high grain yield with less water input (George et al, 2002;Bouman et al, 2005). However, yield decline or yield failure in continuously monocropped aerobic rice (CMAR) system has been reported since 1970s (Nishizawa et al, 1971;Ventura and Watanabe, 1978;George et al, 2002;Peng et al, 2006;Kreye et al 2009a), which was a major constraint to the widespread adoption of aerobic rice technology. The growth inhibition and yield decline or yield failure of aerobic rice continuously monocropped are generally believed to be caused by soil sickness (Nishizawa et al, 1971).…”

Declining water is a great concern in production of rice, because rice is more sensitive to water deficiency which restricts normal rice growth resulting in enormous economic loss. A field experiment was conducted to study the effect of hydrogel in different sowing techniques of aerobic rice viz. flat, ridge, and bed sowing. Observations on soil moisture percentage before every irrigation, yield, and yield components of rice were recorded. Application of hydrogel improved soil moisture contents in all the three sowing techniques as compared to soil without hydrogel. More soil moisture contents met the crop water needs and increased the number of germinated seeds. As a consequence of more emergence and better stand establishment, the yield components were also improved increasing the yield of rice in hydrogel amended soil in all sowing techniques. However, sowing of rice on beds with hydrogel amendment was found the most effective; it not only improved the performance of aerobic rice but also enhanced growth and yield of aerobic rice more than other sowing techniques.

“…In a companion paper, the authors suggest that the use of irrigation water from shallow tubewells might have increased the soil pH, thus inducing micronutrient deficiencies [302]. The authors suggest also that further research is needed, regarding the role of micronutrients, especially iron and manganese, in contributing to the sharp reductions in yield and in the yield failures observed on aerobic rice fields in the tropics [303].…”

Rice production is susceptible to damage from the changes in temperature and rainfall patterns, and in the frequency of major storm events that will accompany climate change. Deltaic areas, in which millions of farmers cultivate from one to three crops of rice per year, are susceptible also to the impacts of a rising sea level, submergence during major storm events, and saline intrusion into groundwater and surface water resources. In this paper, I review the current state of knowledge regarding the potential impacts of climate change on rice production and I describe adaptation measures that involve soil and water management. In many areas, farmers will need to modify crop choices, crop calendars, and soil and water management practices as they adapt to climate change. Adaptation measures at the local, regional, and international levels also will be helpful in moderating the potential impacts of climate change on aggregate rice production and on household food security in many countries. Some of the changes in soil and water management and other production practices that will be implemented in response to climate change also will reduce methane generation and release from rice fields. Some of the measures also will reduce the uptake of arsenic in rice plants, thus addressing an important public health issue in portions of South and Southeast Asia. Where feasible, replacing continuously flooded rice production with some form of aerobic rice production, will contribute to achieving adaptation objectives, while also reducing global warming potential and minimizing the risk of negative health impacts due to consumption of arsenic contaminated rice.
