Soybeans usually produce well in North Dakota. This replicated trial had 20 soybean varieties, including several natto type soybeans.
MATERIALS AND METHODS
Soil: |
Embden loam and Maddock sandy loam; pH=7.4; 2.2% organic matter; soil-P and soil-K were very high; soil-S was low. |
Previous crop: |
2001 - sweetcorn and tomato; 2000 - carrot; 1999 - pepper and field corn. |
Seedbed Preparation: |
Coulter chiseled 15 inches deep on April 18. Multiweeded (field cultivated) three times; once on May 14 to smooth seed bed and twice on May 15 to incorporate herbicide. |
Planting: |
Planted on May 15 in 30-inch rows. All beans were inoculated just prior to planting. |
Plots: |
Plots were 17 ft long by 10 ft (4 rows) wide. There were four reps. |
Fertilizer: |
Broadcast 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24 on Apr 18. |
Irrigation: |
Overhead sprinkler irrigation as needed. |
Pest control: |
Weeds were controlled with Sonalan (2 pt/acre preplant incorporated on May 15), Lasso (2 qt/acre on May 16), Poast + Dash (1.5 pt/acre + 1 pt/acre on June 12), Raptor + COC (4 oz + 2 pt/acre on June 20), and by hand weeding. Sprayed Benlate (0.5 lb/acre on July 9) to control disease. |
Harvest: |
Harvested on October 14 with a Hege plot combine. |
Plants lodged more this year than in most previous years. This may have reduced yields.
