| Soybean Variety Trial | ||||||||||||||
| L. Besemann and H. Eslinger | ||||||||||||||
| Two soybean variety trials were conducted at the Oakes Irrigation Research Site; a Roundup Ready@ trial and a Liberty Link trial. Results for the Roundup Ready trial are listed in Table 1. Results for the Liberty Link trial are listed in Table 2. There were forty-six varieties in the Roundup Ready trial and ten varieties in the Liberty Link trial. | ||||||||||||||
| MATERIALS AND METHODS | ||||||||||||||
| Soil: | Embden loam and Egeland loam; pH = 7.3; 1.8% organic matter; soil N 25 lbs/acre; soil P and soil K were very high; soil S was high. | |||||||||||||
| Previous crop: | 2014 – field corn. | |||||||||||||
| Seedbed preparation: | Spring conventional tillage. | |||||||||||||
| Planting: | Planted May 20 in 30-inch rows. | |||||||||||||
| Plots: | Plots were 17 ft long by 5 ft (2 rows) wide. The study had four replications. | |||||||||||||
| Fertilizer: | Broadcast 8 lbs N/acre, 42 lbs P2O5/acre, 48 lbs K2O/acre and 10 lbs S/acre as 9‑21‑24-6 April 13. | |||||||||||||
| Irrigation: | Overhead sprinkler irrigation as needed. | |||||||||||||
| Pest control: | The Liberty Link and Roundup Ready soybean both received: Trust (1 pt/acre) May 19 weed control; Endura (8 oz/acre) July 8, Proline (5 oz/acre) July 23 controlled disease. Kendo (3 oz/acre) August 11 controlled insects. Additional weed control: Liberty Link soybeans received Liberty (34 oz/acre) + AMS (1.5 lb/10 gal) June 18, Liberty (28 oz/acre) + AMS (1.5 lb/10gal) June 30. The Roundup Ready soybeans received Roundup (30 oz/acre) + AMS (1 lb/10 gal) June 18, Roundup (20 oz/acre) + AMS (1 lb/10gal) June 30. | |||||||||||||
| Harvest: | October 8 with a plot combine. | |||||||||||||
| RESULTS | ||||||||||||||
| Yields in the Roundup Ready trial averaged 77.9 bu/acre. Yields in the Liberty Link trial averaged 74.4 bu/acre. | ||||||||||||||
