SOYBEAN VARIETY PERFORMANCE TRIAL

W. Albus, L. Besemann and H. Eslinger

 

Results summary

           Soybeans are a major dryland crop in central and southeastern North Dakota.  Historically dry edible beans have pre-empted soybeans in irrigation rotations in this area of the State.  The present market price for soybeans and less risk in their production have resulted in more irrigated acres.  This trial was initiated to provide producers with yield and agronomic information on soybean varieties in an irrigated environment.

 

MATERIALS AND METHODS

 

 

Soil:

Maddock sandy loam and Embden sandy loam; pH=7.3; 1.8% organic matter; soil-P was very high, soil-K was medium and soil-S was medium.

Previous crop:

2006 ‑ field corn; 2005 ‑ cabbage, carrot, onion and potato; 2004 ‑ sweetcorn.

Seedbed

Preparation:

Flailed, disked and coulter chiseled in the fall; Coulter chisel lightly once on April 26.  Multiweed (field cultivate) twice on May 8 to smooth the seedbed and to incorporate herbicide.

Planting:

Planted soybeans on May 16 in 30-inch rows.  All beans were inoculated just prior to planting.

Plots:

Plots were 17 ft long by 10 ft (4 rows) wide.  There were 4 reps.

Fertilizer:

November 2006, broadcast 9 lbs N/acre, 43 lbs P2O5/acre, 101 lbs K2O/acre and 13.5 lbs S/acre as 11-52-0, 0-0-60 and 90% elemental sulfur.

Irrigation:

Overhead sprinkler irrigation as needed.

Pest control:

Trust (1½ pt/acre) on May 8, and Fusilade (8 oz/acre) + MSO (1pt/acre) on June 28.  Glyphosate Original (1qt/acre) + NIS (0.05%v/v) + AMS + (1 lb/10 gal) on June 5, Cornerstone (40 oz/acre) + AMS (1 lb/10 gal) on June 29, Cornerstone (48 oz/acre) + AMS (1 lb/10 gal) + NIS (0.5%v/v) on July 7; for weed control.  Topsin (1 lb/acre) on July 3 and July 11 for disease control.  Lorsban (1 pt/acre) on August 3 for insect control.

Harvest:

Harvested on October 4 with a Hege plot combine.

 

RESULTS

 

           Yield, test weight, flowering date, maturity date and lodging were significantly affected by variety.  Forty varieties averaged 67.5 bu/acre.  The difference between the lowest and highest yielding variety was only 13.2 bu/acre.  This is surprising since maturities ranged from a group 0.007 to a group 1.5.
