Optimizing Nitrogen Fertilization Managements Under Mechanical Deep Placement for Raising Rice Grain Yield
It is not known whether both reducing tiller-fertilizer and increasing panicle-fertilizer can significantly increase grain yield under mechanical deep placement. The two-year field experiment was conducted to ...

Effects of Nitrogen Fertilizer Rate Under Deep Placement on Grain Yield and Nitrogen Use Efficiency in Mechanical Pot-seedling Transplanting Rice
Rice yield and nitrogen use efficiency will be affected by different nitrogen (N) application rate. However, previous studies were limited on different nitrogen fertilization rate under deep placement. In orde...

γ-Aminobutyric Acid Regulates Grain Yield Formation in Different Fragrant Rice Genotypes Under Different Nitrogen Levels
The influences of γ-aminobutyric acid (GABA) and nitrogen on grain yield, yield-related traits, plant growth, grain–leaf ratio and NSC contents in different fragrant rice genotypes are not fully understood. A ...
