FIELD CORN HYBRID PERFORMANCE TRIAL, 1998
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 75 hybrids.

Table 24. Oakes irrigated field corn grain test yield and agronomic data.

MATERIALS AND METHODS

Soil: Maddock sandy loam; pH=7.3; 2.4% organic matter; soil-P and soil-K were very high; soil-S was very low.

Previous crops: 1997 - cabbage, broccoli, oriental vegetable and onion; 1996 - carrot and potato; 1995 - soybean and field corn.

Seedbed preparation: Disked on 31 October 1997. Multiweeded (field cultivated) to incorporate fertilizer and smooth seed bed on April 28.

Planting: Planted April 30 in 30-inch rows. Thinned to 28,000 plants/acre on June 12.

Plots: 17 ft long by 7.5 ft (3 rows) wide. There were 4 reps.

Fertilizer: On April 13, 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 28-0-0 preplant on April 28 to bring total nitrogen (soil-N plus applied N) to 116 lbs N/acre. Knifed in 100 lbs of N/acre as 28-0-0 on June 8.

Irrigation: Overhead sprinkler irrigation as needed.

Pest
Control:
Weeds were controlled by Cypro A + Frontier (1.6 lbs and 16 oz/acre on April 30), Stinger (spot applied at pt/acre on May 18), cultivation (June 16) and hand weeding. Sprayed DiPel (1 lb/acre on June 26 and June 29) and chemigated Asana (8 oz/acre on July 9) for European corn borer control.

Harvest: Harvested with a plot combine on September 29 and October 1.
