SOYBEAN VARIETY PERFORMANCE TRIAL, 2000

Table 31. Results of the 2000 soybean performance trial.
Soybeans usually produce well in North Dakota. This replicated trial had 20 soybean varieties, including several natto type soybeans.
MATERIALS AND METHODS
| Soil: | Embden sandy loam, Hecla sandy loam and Maddock sandy loam; pH=6.8; 2.5% organic matter; soil-P, soil-K , and soil-S were very high. |
| Previous crop: | 1999 - field corn and tomato; 1998 - carrot; 1997 - squash, pumpkin and pepper. |
| Seedbed preparation: | Disked on 29 October 1999. Multiweeded (field cultivated) once April 4 and twice May 9 to incorporate herbicide and prepare seedbed. |
| Planting: | Planted on May 9 in 30-inch rows. |
| Plots: | Plots were 17 ft long by 10 ft wide. There were 4 reps. |
| Fertilizer: | On April 4, broadcast 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24. Fertigated 100 lbs N/acre as 28-0-0 on July 13. |
| Irrigation: | Surface drip irrigation as needed. |
| Pest control: | Weeds were controlled by Sonalan (2 pt/acre on May 9, preplant incorporated), Dual (1.5 pt/acre on May 9), Raptor + COC (4 oz/acre + 2 pt/acre on June 7), and hand weeding as needed. |
| Harvest: | Harvested on Oct 3 with a Hege plot combine. |

1Yield adjusted to 13% moisture.
2Lodging is from 1 to 5: 1 is erect; 5 is flat on ground.
3Chlorosis - 1 to 10; the lower the score, the worse the chlorosis. During the early to mid part of the growing season I noticed that the stands were not uniform and many plants were chlorotic. On June 29 I took notes to document these conditions. We then applied nitrogen and the chlorosis disappeared, indicating it was due to N deficiency. These soybeans were not inoculated before planting.
