Soybean trials were conducted at this location during the 2000 growing season. However, extremely high temperatures and drought caused considerable variation in performance among plots within the tests. After careful analysis and review of the data, it is the opinion of the editors that the results of this trial may not accurately reflect the performance potential of all test entries. Since this data could be potentially be misleading if used in making decisions concerning variety selection, we have chosen not to present them in this publication. Results from these tests will be provided upon request. |

| 1. Yields calculated at 13% moisture. | |||||||||
| 2. Lodging rating: Rated 1 (all plants erect) to 5 (over 80% of plants down). | |||||||||
| 3. Seed quality rating: Rated 1 (very good) to 5 (very poor). | |||||||||
| 4. Shattering rating: Rated 1 (no shattering) to 5 (>50% pods shattered). | |||||||||
| 5. CV = 29.5% and df for EMS = 27. | |||||||||
| Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's protected LSD (P = 0.10). | |||||||||
| Planted: | June 5, 2000. | ||||||||
| Harvested: | Maturity Group V - October 17, 2000 | ||||||||
| Seeding Rate: | Eight viable seeds per foot in 30" rows. | ||||||||
| Soil Type: | Dothan loamy fine sand. | ||||||||
| Soil Test: | P = Medium, K = Medium, and pH = 6.1. | ||||||||
| Fertilization: | 0 lb N, 40 lb P2O5, and 80 lb K2O/acre. | ||||||||
