Land consolidation involving the joining of small paddy fields to form a large-size field has been promoted recently in Japan in order to increase the efficiency of rice production. However, the varia...
Utilization Advantages of Controlled Release Nitrogen Fertilizer on Paddy Rice Cultivation
transplanting cultivation direct sowing cultivation single basal application
2009/9/9
Labor-saving for fertilization has been strongly desired due to the shortage in labor and increasing scale of farming for rice cultivation. In order to clear these problems, the effect of application ...
Varietal Differences of Juvenile Phase Duration and Photoperiodic Sensitivity in Paddy Rice
Cropping area Juvenile phase Paddy rice Photoperiodic sensitivity Varieties
2009/8/6
The juvenile phase and photoperiodic sensitivity of 13 Japanese paddy rice varieties were investigated. The duration of juvenile phase was determined by counting the days of insensitivity to a short-d...
Promotion of Seedling Emergence of Paddy Rice from Flooded Soil by Coating Seed with Potassium Nitrate
Calcium peroxide Direct sowing Foliage leaf emergence Germination Paddy rice Pelleted seed
2009/8/6
Emergence and establishment of seedling of paddy rice sown into flooded soil are poor but promoted when seeds are coated with O2 generator CaO2. It has been commonly understood that this is because C...
