Comparative Effects of Flooded and Unflooded Soil Conditions and Nitrogen Application on Growth and Nutrient Uptake by Rice Plants1

  1. M. S. Chaudhry and
  2. E. O. McLean2



Unflooded conditions caused delayed flowering, high percentage sterility, and consequent low yields. Nitrogen increased the cation exchange capacity of the roots and increased the yields when applied to the flooded soil at tillering stage. Plant P and Mn contents were low under unflooded conditions, but this did not appear to be the basic cause for the abnormal growth under these conditions.
