9 11. 9 21. 5 16. 8 1527] SPRING WHEAT PRODUCTION IN ILLINOIS 347 DATE OF SEEDING SPRING WHEAT The importance of sowing spring wheat early was demonstrated by a series of date of seeding experiments conducted at Urbana from 1918 to 1922. In these experiments the first sowings were made as early in March as the condition of the soil would permit seeding with a drill. Thereafter seedings were made at intervals of as near to ten days as soil and weather conditions allowed. Close adherence to a def...inite time schedule was impossible, owing to the condition of the soil. At times the last seeding was delayed until the latter part of April, altho it was intended to sow not later than the first week of April. It will be observed that the highest yield made by both Marquis and Illinois No. 1 was secured each year from the first seeding (Table 7). Not only was there a progressive decrease in yield with later seedings, but the quality of the crop usually declined, as shown by the weight per bushel.
