Effect of Sunn Hemp and Peanut Incorporated as Green Manures on Growth and Nitrogen Uptake of the Succeeding Wheat
C-N ratio Green manure Nitrogen fixation Nitrogen mineralization Peanut
2009/7/30
Effect of summer legumes incorporated as green manures, sunn hemp (cv. Kobutoriso) and peanut (cv. Chiba-handachi), was examined for nitrogen contribution to the succeeding wheat (cv. Norin 61). The d...
Correlation of the Amount of Nitrogen Accumulated in the Aboveground Biomass at Panicle Initiation and Nitrogen Content of Soil with the Nitrogen Uptake by Lowland Rice during the Period from Panicle Initiation to Heading
Nitrogen uptake Oryza sativa L. Precision agriculture Recovery ratio Soil nitrogen Topdressing
2009/7/29
To estimate the site-specific optimal amount of nitrogen (N) to be applied as top-dressing (N top-dressing) at panicle initiation, we examined the effects of the amount of N accumulated in the abovegr...
Responses of a Supernodulating Soybean Genotype,Sakukei 4 to Nitrogen Fertilizer
Glycine max Leaf nitrogen Nitrogen response Photosynthesis Soybean Supernodulation
2009/7/29
The supernodulating soybean genotype Sakukei 4 is potentially high-yielding. We characterized its leaf nitrogen (N) content, photosynthesis and growth at different developmental stages and under diffe...
Nitrogen and Phosphorus Removal from Wastewater by Useful Plants and the Effect of Shading on the Removal Efficiency
Nitrogen removal Phosphorus removal Shading Solar radiation Wastewater
2009/7/22
Nitrogen and phosphorus removal from wastewater by a ditch planted with several plants, including terrestrial species, was studied. The effects on the removal rate by shading were also examined. Papy...
The Effects of Timing of Nitrogen Derssing on the Baking Quality of Winter Wheat
Extensiblity Farinogram Nitrogen dressing Protein content Ratio of loaf volume to weight
2009/7/16
The effects of nitrogen dressing at different growing stages on baking quality were investigated by using the winter wheat breeding line Tohoku205. The relation between flour protein content and ratio...

Effects of Nitrogen Fertilizer Application and Solar radiation on the Growth Response of Sorghum Seedlings to Soil Moisture.
Suppression of Nitrogen Outflow from Bedding Plants Soil by Zeolite or Charcoal
Nitrogen Charcoal Zeolite
2009/7/13
This experiment was carried out in order to clarify the amount of decreased nitrogen flowing from bedding plant soil to which zeolite or crushed charcoal had been added. Nitric acid leaching was obser...
Effect of Nitrogen Topdressing at Jointing Stage or Anthesis on the Kernel Weight of Hokkadido-Bred Wheat Cultivar “Haruyutaka” in Warm Parts of Western Japan
Crop growth rate Haruyutaka Kernel weight Net assimilation rate Nitrogen topdress Overluxuriant growth
2009/7/9
We attempted to increase the kernel weight of Hokkaido-bred wheat cultivar “Haruyutaka” by increasing the net assimilation rate (NAR) without inducing an over-luxuriant canopy during the ripening per...
The effect of nitrogen fertilizing 10 days after heading in wheat
Gluten Triticum aestivum L 10 days after heading Protein content Top dressing
2009/7/9
To increase the protein content of wheat grain, we applied fertilizer 10 days after heading and examined its effect on agronomic character and flour quality. This top dressing did not affect the agro...
Cultivar Differences in Dependence on Nitrogen Fixation of Soybeans in the Field with a High Soil Nitrate Level Determinated by the Relative Ureide Abundance Method
Cultivar difference High soil nitrogen Nitrogen fixation Nodule Relative abundance of ureide
2009/7/8
Nitrogen fixation by soybeans is reduced by high soil nitrate levels. This reduced nitrogen fixation capacity increases the dependence on soil nitrogen, which may result in depletion of soil nitrogen...
