For a yield of 50 bushels per acre, this equals 7 to 10 acre-inches of water.^ With a larger crop the water used would be increased proportionally. Under field condi- tions there must be added to this whatever loss may take place through run-off, evaporation from the soil, and seepage. King found that a yield of 7000 to 8000 pounds.

The crop is therefore dependent on July and August rainfall. of dry matter per acre (approximately a 50-bushel jaeld) required about 12 acre-inches under field conditions. In this case the loss by seepage, run-off, and evaporation must have been about 5 acre-inches (assuming 7 inches used by the crop), but this will vary with the soil, culti- vation, distribution of rainfall during the growing season, and amoimt of storage water in the soil at planting time. 1 Montgomery, E.
