Abstract

Abstract

A comparison was made of rice (Oryza saliva) grown under continuously submerged conditions and under alternately dry and flooded conditions in several greenhouse and field experiments. With nitrogen-deficient soils, alternately dry and submerged conditions caused an appreciable decrease in growth, yield, and nitrogen uptake. With soils high in available nitrogen as a result of being in permanent pasture for several years, drying and reflooding resulted in a yield increase. Drying and reflooding apparently resulted in a loss of soil nitrogen which was detrimental in the nitrogen-deficient soils and beneficial in the soils that had been in pasture.
