When comparing yields or sugars of two varieties, the values must differ by a value equal to or greater than the LSD given at the bottom of each column. If they do not, then they were probably not different in this test.

1 Plot tared individually.
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.
4 Commercial seed obtained locally.
