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...
Seedling Emergence and Establishment of Direct-sown Paddy Rice in Soils Incorporated with Substances Produced in Reductive Paddy Soil
Acetic acid Direct sowing Ferrous iron Paddy rice Seedling emergence Seedling establishment
2009/8/4
Although seedling emergence and establishment is inhibited by soil reduction in the direct sowing of paddy rice into puddled and leveled soil, the reasons for this are not clearly understood. This exp...

Early growth Heading date Leaf emergence rate Rice plant Rooting Seedling age in leaf number
2009/7/29
Eleven kinds of rice seedlings with different plant age in leaf unmber in the range 0-7.2 (counting the incomplete leaf as the first leaf), raised under the same condition, were grown in the phytotron...
Effects of Mixed Coating of Oxygen Generating Chemicals and Several Kinds of clay on Seedling Emergence in Direct Sowing of Paddy Rice
Calcium peroxide Clay Emergence of seedling Direct sowing into flooded soil Soil oxidation Paddy rice
2009/7/27
The effects of mixed coating of seed with oxygen-generating chemicals containing 16% calcium peroxide (CaO2) and clay on the seedling emergence of rice (Oryza sativa L.) from flooded soil were examine...
Breeding of Rice for a High Seedling Emergence Rate in Direct Seeding under a Submerged Soil Condition
Direct Seeding Evaluation Method Gene Source Rice Seedling Emergence
2009/7/9
Rice lines with a high seedling emergence rate were screened by sowing the seed 20 or 30 mm deep from the soil surface at 20°C or 25°C in a growth chamber, or placing the seeder-tape 20 mm deep from ...
Application of the Method of Rice Seedling Emergence in Flatly Arranged Nursery Boxes to the Normal-season Culture of Rice in Gunma Prefecture—The relationship between covering materials and emergence of seedlings
Covering materials Emergence in nursery boxes arranged flatly Normal-season culture Nursery box
2009/7/9
In Gunma Prefecture, rice seedlings are usually grown in nursery boxes kept stacked up by the pool-raising method. In this method, however, the boxes need to be moved several times, which is a labori...
Formation and Emergence of Crown Roots in Rice Seedlings Transplanted after Root–Pruning
Transplanting Rooting Crown root Primordia Leaf emergence
2009/7/8
Effects of root pruning on the formation and the emergence of crown roots in young rice seedlings were examined. The seedlings at the 3.2 leaf stage after pruning all roots were transplanted to the pa...
Influence of Draining after Direct Seeding of Rice under Submerged Conditions on Seedling Emergence and Establishment in Relation to Three-Phase Structure of Soil
Coleoptile Drainage of flooded water First leaf Rice Seedling emergence Seedling establishment
2009/7/8
The effects of draining after submerged direct seeding were investigated in pot experiments to improve emergence and establishment of rice seedlings in the new direct seeding method using a "shooting...
Studies on the Cultivation of Dibbling 3 Seeds per Hole for Improving Seedling Emergence and Establishment of Soybean—The Effect of the Number of Seeds Dibbled per Hole on the Emerging Force of the Seedlings
Dibbling cultivation Emerging force Number of seeds dibbled per hole Seedling emergence and establishment
2009/7/8
We examined the effect of the number of soybean seeds dibbled per hole on the seedling emergence and establishment on crust-forming soil in order to improve the unstable emergence and establishment c...
Factors Causing Submergence Damage on Soybean Seedling Emergence under No-Till Culture Conditions
No-till culture Seedling emergence Soybean Submergence damage
2009/7/8
Soybean yield in Aichi prefecture, Japan, has been low and unstable due to excess soil moisture during seeding time. We have been developing the production technology including no-till culture to red...
