1. Price Index based on two-year average (1998-1999) prices for U.S. government grades.
2. Numerical values ranging from 1-99 for flue-cured tobacco based on equivalent government grades - higher the number, higher the grade. Some varieties are not shown due to low plant counts from TSWV.
* Unreleased variety.

Conducted on an Ocilla loamy sand soil fertilized with 1000 lb/acre of 6-6-18 and 120 lb/acre 16-0-0 with plants spaced 20-22 inches apart in 44-inch rows.
1. Price Index based on two-year average (1998-1999) prices for U.S. government grades.
2. Numerical values ranging from 1-99 for flue-cured tobacco based on equivalent government grades - higher the number, higher the grade. Some varieties are not shown due to low plant counts from TSWV.
