FIELD CORN HYBRID PERFORMANCE TRIAL
Harold Cross, NDSU Plant Science Department
Richard Greenland and Leonard Besemann
Corn generally grows very well in this area of North Dakota. The short summer is compensated for by long days and lots of sunshine. This performance trial tested 64 hybrids.
Table 13. Oakes irrigated field corn grain test yield and agronomic data.
MATERIALS AND METHODS
| Soil: | Maddock sandy loam and Hecla sandy loam; pH=6.9; 2.8% organic matter; soil-P and soil-K were very high; soil-S was very low. |
| Previous crops: | 1996 - commercial pepper production; 1995 - cabbage; 1994 - buttercup squash. |
| Seedbed preparation: | Disked on May 6. Multiweeded to incorporate fertilizer and smooth seed bed on May 6. |
| Planting: | Planted May 9 in 30-inch rows. Thinned to 28,000 plants/acre on June 24. |
| Fertilizer: | On April 23, broadcast 14 lbs N/acre and 70 lbs P2O5/acre as 10-50-0, 16 lbs N/acre and 19 lbs S/acre as 21-0-0-24, and 94 lbs K20/acre as 0-0-60. Sprayed 70 lbs N/acre as 28-0-0 on May 5. Knifed in 150 lbs of N/acre as 28-0-0 on June 20. |
| Irrigation: | Underground drip system as needed. |
| Pest Control: | Sprayed Frontier and Bladex (1 pt and 1.5 lbs/acre on May 9) and Buctril (1.5 pt/acre on June 19) for weed control. |
| Harvest: | Harvested with a plot combine on October 20. |
