1Lint yield calculated using best estimates of seed cotton yield (mean from 4
reliable Delta locations (Stoneville, Tunica, Sumner, and Elizabeth) and
gin turnout from locations processed on the micro-gin (Stoneville and
Tribbett).
2Color and leaf grade values are the mode of 12 observations per entry.
3 Premiums are based on USDA loan schedule, value is calculated as
premium plus USDA loan base price (52.55 cents per pound), gross return
is calculated as lint yield times value.
Values in bold type are not statistically different than the highest
value in each column at the 5% probability level.
