Strategies for Controlling the Apple Snail Pomacea canaliculata (Lamarck) (Gastropoda: Ampullariidae) in Japanese Direct-Sown Paddy Fields
golden apple snail management rice direct seeding
2009/9/9
The apple snail Pomacea canaliculata becomes a much more serious pest in direct-sown rice fields than in transplanted fields. In south Japan, it represents an important constraint on the implementatio...
Method to Evaluate “Uplandization” in Converted Field from a Paddy Based on Crystallinity of Free Iron Oxides
redox reaction phosphate sorption soil microstructure
2009/9/9
Uplandization” is the process that changes the physical and chemical properties in a paddy field into those of an upland field. There is a transitional period when a paddy field is converted to an upl...
Patterns of Soil Nitrogen Release in Paddy Fields of Warm Regions in Japan and Diagnosis of Fertilizer Application : II. Characteristics of soil nitrogen mineralization and nitrogen uptake patterns of rice plants in Fukuoka Prefecture
Amount of nitrogen uptake Fertilizer nitrogen Nitrogen mineralization Paddy soils Soil nitrogen
2009/8/4
Topsoils collected from various regions in Fukuoka Prefecture were incubated and the amount of mineralized nitrogen was measured. The relationship between the mineralized nitrogen amount (N) and the ...

2009/7/28
We examined the possible benefit of rational site-specific crop management practices in 17 paddy fields located in an area of 2.0 ha for the prevalence of precision agriculture methods on a cooperativ...
Effects of Planting Pattern on the Interception of Solar Radiation by the Canopy and the Light Extinction Coefficient of the Canopy in Rice Plants Direct-sown in a Submerged Paddy Field
Crop growth rate Direct sowing Interception of solar radiation Light-intercepting characteristics Planting pattern Rice
2009/7/24
In order to investigate effects of planting pattern on the interception of solar radiation by the canopy and the light extinction coefficient of the canopy in rice, the rice plants direct-sown in a su...
Effects of Temperature,Sowing Depth and Soil Hardness on Seedling Establishment and Yield of Cambodian Rice Direct-seeded in Flood Paddy Fields
Growth Low temperature Seedling establishment Sowing depth Water drainage before sowing Yield
2009/7/23
Rice is the most important crop for supporting Cambodian economy, however the cultivated area is limited due to the rice production system. Rice is transplanted by hand and yet the direct-seeding tech...
