Two varieties of alfalfa, Medicago sativa L., ‘Kentucky Syn. Z 1 ’ and ‘Narragansett,’ were grown in glazed tiles 90 cm deep with water tables of 15, 30, and 45 cm from the surface. When the water‐tables were raised immediately after the harvest, the dry matter yield was drastically reduced in both varieties. No significant yield difference was found when the treatments were applied 14 or 28 days after harvest. The highest yield was obtained when water table was held 45 cm from the surface and when applied 14 or 28 days after harvest.
