Soybean Variety Trial
L. Besemann and H. Eslinger
          One soybean variety trial was conducted at the Oakes Irrigation Research Site, a Roundup Ready® trial.  Results for the Roundup Ready trial are listed in Table 1.  The trial had 47 varieties.
MATERIALS AND METHODS
Soil: Embden loam, Embden Sandy Loam and Maddock sandy loam; pH=6.8; 1.6% organic matter; soil N 19 lbs/acre; soil-P was very high; soil-K was high; soil-S was low. 
Previous crop: 2013 – field corn.
Seedbed preparation: Spring conventional tillage.
Planting: Planted May 21 in 30-inch rows.  
Plots: Plots were 17 ft long by 5 ft (2 rows) wide.  The study had four replications.
Fertilizer: Broadcast 25 lbs N/acre, 44 lbs P2O5/acre, 47 lbs K2O/acre and 19 lbs S/acre as 10‑18-19-8 April 21.
Irrigation: Overhead sprinkler irrigation as needed.
Pest control: Trust (1 pt/acre) May 21, Roundup Power Max (20 oz/acre) + AMS (1 lb/10 gal) June 24,    Section 2EC (8oz/acre) +COC (1pt/acre) July 9 controlled weeds.  Endura (8 oz/acre) July 17 and July 25, T-Methyl (26 oz/acre) July 31 controlled disease.    Kendo (3 oz/acre) July 17 controlled insects.
Harvest: October 9 with a plot combine.
RESULTS
         Yields in the Roundup Ready trial averaged 67.1 bu/acre.
