Soybean Variety Trial
L. Besemann and H. Eslinger
      Two soybean variety trials were conducted at the Oakes Irrigation Research Site, a non‑GMO (conventional trial) and a Roundup Ready® trial.  Results for the conventional trial are listed in Table 1 and results for the Roundup Ready trial are listed in Table 2.
MATERIALS AND METHODS
Soil: Egeland loam and Maddock sandy loam; soil N 42 lbs/acre. 
Previous crop: 2012 – wheat.
Seedbed preparation: Spring conventional tillage.
Planting: Planted May 28 in 30-inch rows.  
Plots: Plots were 17 ft long by 5 ft (2 rows) wide.  The study had four replications.
Fertilizer: Broadcast 34 lbs N/acre, 81 lbs P2O5/acre, 103 lbs K2O/acre and 19 lbs S/acre as 8‑20-26-5 May 1.
Irrigation: Overhead sprinkler irrigation as needed.
Pest control: Weed control:  
     Roundup Ready and conventional:  Trust (1 pt/acre) May 28.
     Conventional:  Basagran (1.5 pt/acre) + COC (1.25% v/v) June 26, Raptor  (4 oz/acre) + NIS (0.25 % v/v) 
                            + AMS (1.5 lb/10 gal) July 5.  
     Roundup Ready: Roundup Power Max (30 oz/acre) + AMS (1 lb/10 gal) June 24 and (40 oz/acre) + AMS
                                (1 lb/10 gal) July 16.  
Disease control:  Proline (5 oz/acre) July 18, July 24 and August 1.  
Insect control:  Kendo (3˝ oz/acre) July 24.
Harvest: October 22 with a plot combine.
RESULTS
      Yields in the Conventional trial averaged 57.2 bu/acre and the Roundup Ready trial averaged 73.8 bu/acre.
