1Lint yield calculated using best estimates of seed cotton yield (mean from 5
Delta locations) 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.
3Premiums 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.
