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...
Characteristics of Dry Matter Production in Rice Plants, Cultivar Takanari Sown Directly in Submerged Paddy Field Compared with Conventionally Transplanted Plants(Agronomy)
Direct-sown rice in submerged field Dry matter production Extinction coefficient Grain yield
2009/7/10
Dry matter production and the related characters in the rice plants sown directly in the submerged paddy field or in the drained field after puddling were compared with those in conventionally transpl...
Effect of Unevenness in a Paddy Field on the Early Growth and Tillering in Direct Seeding Cultivation of Rice(Agronomy)
Depth of water Direct seeding Early growth Lower nodal tiller Maximum number of tillers
2009/7/10
To clarify the effect of unevenness in a field on the tiller development of direct-seeded rice plants, we investigated the height and growth at the same measuring points. The paddy field had a high de...
Alleviation of the Calcium Nitrate-Induced Suppression of Seedling Emergence by Seed Coating with Oxygen Supplier and Soil Puddling before Seeding in Direct-Seeding Rice in Submerged Paddy Field
Oxygen supplier Puddling Direct seeding of rice in submerged paddy field Apple snail Calcium cyanamide
2009/7/9
The effect of seed coating with oxygen supplier on the suppression of rice-seedling emergence by calcium nitrate applied to control apple snail, was examined in pots and petri dishes. The seed coatin...
Correlation of Lodging Resistance with Physical Characteristics of the Basal Culm and Rooting Behavior in Rice Direct Seeded in a Flooded Paddy Field
Bending stress Breaking strength of culm with leaf sheaths Crown root Growth angle of root
2009/7/8
In submerged direct seeding such as hill seeding and row seeding, lodging was not caused easily compared with broadcast seeding. Not only deep rooting but also physical characteristics of the basal cu...
