When comparing yields or sugars of two varieties, the values must differ by a value equal to or greater than the LSD give at the bottom of each column. If they do not, then they were probably not different in this test. Planted April 22, 1999; Harvested October 5,1999. ¹ Root yields have been tared 5%. ² Curly Top Ratings: 0 = no curly top symptoms; 9 = plants killed. To calculate and compare the average curly top resistance of two or more varieties, use only those years data in which the compared varieties all have ratings. ³ Commercial check varieties, seed obtained locally. ⁴ All check varieties received 24 oz/A Progress, May 17; 24.0 oz/A Progress + 0.5 oz/A Upbeet, May 25 and June 4. 27.0 oz/A Liberty or 32.0 oz/A Roundup applied to appropriate resistant varieties June 4, June 11 and June 16.
