| Soil Test: | pH 7.0 P 46 K 206 |
| Fertilizer Applied: | 190# 7-34-20, 150#N sidedress |
| Herbicide Program: | 5 qt. Extrazine and 1 pt. Weedone applied on one replication with water on 4/30/97 and on the other two replications on 5/17/97 with 28% N. |

| Harvest Date: | Oct. 21 |
These plots compared row-applied N-P-K fertilizer to row-applied N only with P and K broadcast. Plots were field length replicated three times and completely randomized.
| Treatments | Yield |
|---|---|
| Row N-P-K | 82.3 bu./A |
| Row N/Broadcast P&K | 82.1 bu./A |
No significant difference with lsd of 6.2 bu/A at the 5% level of probability. Coefficient of variation equaled 2.1%.
Low corn yields were due primarily to wet conditions at planting as well as dry conditions in July and August. Corn did not tassel until late July.
