We recently analyzed 16 years of data from a nitrogen rate study at Monmouth, Illinois. The observed best nitrogen rate for corn following corn ranged from 53 to 240 pounds of nitrogen per acre, depending on the year.The predicted best rate of nitrogen based on all 16 years of data was 147 pounds per acre, with a yield of 144 bushels per acre, or slightly more than 1 pound of N per bushel.he pounds of nitrogen per bushel of yield ranged from 0.6 to 2.1, and in only 2 years of the 16 did it fall within the range of 1.1 to 1.2 pounds N per bushel. The variability of these results did not surprise us; we've seen such swings in virtually every study we've conducted.
