Adaptation of Rice to Flooded Soils

2013
This paper and its companion (Colmer et al., 2014) review research on the adaptation of rice (Oryza sativa L.) to the wide range of semi-aquatic environments in which it grows. The paper considers well-regulated flooding to 5–20 cm depth; the companion considers deeper flooding in rainfed conditions.

The impact of rice plant roots on the reducing conditions in flooded rice soils

Chemosphere, 2006
The impact of oxygen diffusion from plant roots on the soil redox in the root zone in flooded rice bays was investigated using two Australian rice growing soils. The rates of production of Fe(II) and Mn(II) in pore water resulting from the reduction of soil minerals was used to gauge the extent of development of anaerobic conditions and the time taken ...

Characterizing flood-prone rice areas and predicting flooding hazards

Journal of Hydrology, 1989
Abstract A methodology to characterize flood-prone rice-growing areas and to predict their flooding hazards in rice culture was pursued using limited and easily-generated hydrologic data from a river flood plain. A computer model established the relationships of a given flooding event with the areal extent of affected and depth of flood water and ...

Flood Damage to Rice Crop in Bangladesh

Geographical Review, 1993
EVERY year, almost one-third of Bangladesh is flooded. However, because of topographical characteristics, the regions of the country experience varied degrees of flooding; some parts may be under deep floodwater, others unaffected. Flooding is beneficial only within certain limits of timing, duration, and magnitude (Paul 1984; Rasid and Paul 1987).

Microbial Ecology of Flooded Rice Soils

1980
More than 90% of the rice fields in Asia are cultivated with the soil submerged during most of the growth period. Wetland rice fields are of three types: irrigated, shallow-water rain fed, and deep-water rain fed. Management practices in an irrigated rice field include: (1) leveling the land and constructing levees to impound water; (2) puddling of wet

Scheduling Irrigation on Non-Flooded Rice

2011 Louisville, Kentucky, August 7 - August 10, 2011, 2011
While continuous-flood irrigation, the most common method for US rice production, can have a fairly high application efficiency, factors such as soil variability and the size of most Mid-South farming operations combine to reduce the efficiency in many cases.

Response to flooding: submergence tolerance in rice.

2014
Abstract This chapter discusses submergence tolerance as a response to flooding, focusing on rice as a model crop where progress was made in developing flood-tolerant varieties and where opportunities exist for further improvements through mining the enormous genetic diversity available in preserved collections worldwide. The impacts of climate

Genetics and Breeding of Flooding Tolerance in Rice

2018
Flooding is a frequent natural calamity, affecting global food supply and financial security. The intensity of rainfall events is expected to increase under future climate change scenarios, which will greatly impact rice production. Different flooding patterns can cause damage or complete yield loss in rice plants at different stages of growth.

Dissipation of Bentazon in Flooded Rice Fields

Journal of Environmental Quality, 1989
AbstractThe dissipation of bentazon (3‐isopropyl‐1H‐2,1,3‐benzothiadiazin‐4(3H)‐one 2,2‐dioxide) in water, soil and vegetation from three flooded rice (Oryza sativa L.) fields was investigated in California. Regression analyses were used to describe dissipation and to determine half‐lives.

Water balance of flooded rice paddies

Agricultural Water Management, 1977
Abstract Rice ( Oryza sativa L., var. Labelle) was grown in 300 m 2 paddies of Beaumont clay soil (Typic pelludert) and subjected to two management schemes of flooded rice culture. These schemes were continuous irrigation and intermittent irrigation.
