Statistical tests were conducted to determine whether differences were caused by variations in environment or were true variety differences. The CV value in a given test trial at each location is a measure of experimental error associated with the test trial. In 1997, however, the CV values were low and experimental error was not a major factor in any test trials. All of these may or may not be controllable in a given year. Moisture Content .
Moisture content is expressed as the percentage of moisture in the shelled corn at harvest.
Moisture is inversely related to maturity. Because maturity is of prime importance in South Dakota, moisture figures are also of considerable importance in the evaluation of the trial entries. Hybrids that provide satisfactory yields and can be stored without additional drying are desirable. Use of tables. The LSD value indicates how much a variable such as yield must differ between two hybrids before there is a real yield difference.
