Supplemental Nitrogen Fertilizer to Soybeans:IV. Influences of soil conditions on the yield response to supplemental nitrogen
Glycine max Nitrogen fertilizer Nitrogen fixation Soil Soybean
2009/8/6
The influence of soil conditions on increase of nitrogen assimilation and yield as a result of supplemental nitrogen fertilizer application at flowering were examined with soybean (Glycine max L. Merr...
Supplemental Nitrogen Fertilizer to Soybeans:III. Effects on nitrogen fixation
Acetylene reduction Nitrogen Nitrogen fixation Soybean Top-dressing
2009/8/6
Effects of (NH4)2SO4 top-dressing at the flowering stage to soybeans were investigated in view of its nitrogen fixation and assimilation. Possibility of estimating nitrogen fixation by time course mea...
The Occurrence of Delayed Stem Senescence in Relation to trans-Zeatin Riboside Level in the Xylem Exudate in Soybeans Grown under Excess-Wet and Drought Soil Conditions
Cytokinin Delayed stem senescence Drought stress Sink and source Soil water content Soybean
2009/7/23
Delayed stem senescence (DSS) after pod maturation in soybean (Glycine max) lowers the quality of products in the mechanized harvest. The effects of drought and excess wet soil conditions on the occur...
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...
