| MATERIALS AND METHODS | |||||||||
| Soil: | Embden sandy loam, Hecla sandy loam and Maddock sandy loam; | ||||||||
| Previous crop: | 2012 – field corn. | ||||||||
| Seedbed Preparation: | Strip-till 18 with an Orthman strip-till machine. | ||||||||
| Hybrid: | Pioneer 91Y30. | ||||||||
| Planting: | May 27 @ 205,000 plants per acre in 30 inch rows. | ||||||||
| Plots: | Plots were 37 ft long by 15 ft (6 rows) wide. There were four reps. | ||||||||
| Fertilizer: | All plots received a broadcast application of 31 lbs N/acre, 103 lbs P2O5/acre, 95 lbs K2O/acre, 26 lbs S/acre and 3 lbs Zn/acre as 7‑25-23-6-1 May 3. All plots received 12 lbs N/acre and 40 lbs P2O5/acre as 10-34-0 via strip-till May 18. | ||||||||
| Irrigation: | Overhead sprinkler irrigation as needed. | ||||||||
| Pest control: | Roundup Power Max (30 oz/acre) + AMS (1 lb/10 gal) June 24 and Roundup Power Max (40 oz/acre) + AMS (1 lb/10 gal) July 16. Section 2EC (8 oz/acre) + COC (1.0 % v/v) July 5 controlled weeds. Proline (5 oz/acre) July 18, July 24 and August 1 for disease control. Kendo (3½ oz/acre) July 24 for insect control. | ||||||||
| Harvest: | October 10 with a 4400 JD combine (60 rows 74 feet long, recorded with a weigh wagon). | ||||||||
| RESULTS | |||||||||
| All soybean plots were combine harvested and bulked. The soybean yield was 65.4 bu/acre at 13.3% moisture and with a test weight of 55.7 lbs/bu. | |||||||||
