| W. Albus, L. Besemann and H. Eslinger | ||||||||||||||||||
| MATERIALS AND METHODS | ||||||||||||||||||
| Soil: | Maddock sandy loam and Hecla sandy loam. | |||||||||||||||||
| Previous crops: | 2012 - edible bean and sugarbeet. | |||||||||||||||||
| Seedbed preparation: | Spring conventional tillage. | |||||||||||||||||
| Planting: | May 25, Wensman W7268VT3PRIB in 30-inch rows. | |||||||||||||||||
| Plots: | Plots were 80 ft long by 15 ft (6 rows) wide. The study had three replications. | |||||||||||||||||
| Fertilizer: | Broadcast 34 lbs N/acre, 81 lbs P2O5/acre, 103 lbs K2O/acre, 19 lbs S/acre May 1. Stream bar 60 lbs N/acre May 31 and sidedress 180 lbs N/acre as 28-0-0 June 24. KTS treatments: Trt 1 = none, trt 2 = 2.5 gal/acre, trt 3 = 5 gal/acre and trt 4 = 10 gal/acre June 24. | |||||||||||||||||
| Irrigation: | Overhead sprinkler irrigation as needed. | |||||||||||||||||
| Pest control: | Harness (2 pt/acre) May 23, Laudis (3 oz/acre) + Roundup Power Max (40 oz/acre) + AAtrex 9-0 (0.5 lb ai/acre) + Destiny (0.05 %v/v) + AMS (1½ lb/acre) June 14. | |||||||||||||||||
| Harvest: | October 25 with a 4400 JD combine and recorded via weigh wagon. Harvest area was: Center four rows 77 feet long. | |||||||||||||||||
