Excess Moisture Injury of Soybeans Cultivated in an Upland Field Converted from Paddy : III. Foliar application of urea as countermeasure against excess moisture injury
Dry matter production Excess moisture injury Foliar application of urea Nitrogen fixation
2009/8/6
The purpose of this experiment was to examine whether the foliar application of urea is effective as a countermeasure against excess moisture injury of soybeans [Glycine max (L.) Merr.]. During the fl...
Effect of Narrow Spacing on Grain Yield in Soybeans.
Radiation Interception in Field Grown Soybeans Measured by Integrated Solarimeter Films
Canopy structure Integrated solarimeter films Light interception
2009/8/4
Intercepted solar radiation by each leaflet in two field grown soybean communities was measured by integrated solarimeter films for two consecutive days. These solarimeters are pieces of film (70 mg, ...

Excess moisture injury Flower shedding Nitrogen fixation Photosynthetic rate Pod shedding Seed yield Soybean
2009/7/31
The purpose of this experiment was to examine whether the application of nitrogen (N) fertilizer as ammonium sulfate is an effective countermeasure against excess moisture injury of soybeans [Glycine ...
Leaf Emergence Pattern of Late-maturing Cultivars in Soybeans
Leaf emergence Leaf emergence pattern Leaf emergence rate Sowing date Soybean Turning point of leaf emergence rate
2009/7/30
It is well known that there are a few turning points of leaf emergence rate on the main stem in soybean plants (Glycine max Merr.). On the other hand, it has also been reported that the leaf emergence...
Pod Setting Pattern during and after Low Temperature and the Mechanism of Cold-Weather Tolerance at the Flowering Stage in Soybeans
Cold-weather tolerance Fertilization Flowering stage Low temperature Pod setting pattern Pollination
2009/7/29
The effects of short-term exposure to a low temperature [two weeks, at 18°C/13°C(day/night)] and long-term exposure to a low temperature [four weeks, at 18°C/13°C(day/night)] from the beginning of flo...
Effects of Low Temperature and Shading during Flowering on the Yield Components in Soybeans
Cold weather damage Flowering stage Low temperature Pod Seed yield Shading Soybean Varietal difference
2009/7/29
Northern Japan, Hokkaido has cold weather damage in agriculture almost every four years. Cold weather damage to soybeans [Glycine max (L.) Merr] during flowering is especially severe and is caused by ...
Studies on the Flooding Tolerance and Water Uptake of Seed and Elongation Force of Seedling in Soybeans
Elongation force Emergence Flooding tolerance Soybean seedling Uptake
2009/7/24
Twenty-four soybean (Glycine max (L.) Merr.) varieties were used to investigate the relationship between flooding tolerance, water uptake of seed and elongation force in the period of seed germination...
The Relationship between Dry Matter Increase of Seed and Shoot during the Seed-Filling Period in Three Kinds of Soybeans with Different Growth Habits Subjected to Shading and Thinning
Determinate Dry matter Harvest Index Indeterminate Soybean
2009/7/23
The ratio of dry-matter increase in seed (S) to that in shoot (W), referred to as RS/W, during the seed-filling period may reflect the balance between the assimilate supply and the sink capacity of ha...
High Carbon Requirements for Seed Production in Soybeans [Glycine max (L.) Merr.]
Harvest index in the carbon (HIC) Harvest index in the dry weight (HIW) Increase in the carbon of seed (ICS), Increase in the carbon of whole plant (ICP), Increase in the dry weight of seed (IWS) Increase in the dry weight of whole plant (IWP) Respiration Soybean
2009/7/23
In soybeans, increase in the dry weight of seed (IWS) during the seed-filling period (SFP) is nearly half that of the whole plant (IWP). Hence, the contributions of assimilate during SFP to seed growt...
