Produces are very hesitant to take a fall harvest fearing possible winter injury/winter kill. We compared fall harvesting when the plant was ready to no fall harvest in three experiments and managed three alfalfa variety trials over 7 years with the fall harvest. Winter kill has not occurred, but winter injury occurred one of seven years. Forage yield advantage was 5.7, 8.4, and 2.64 Mg/ha in 2, 3, and 1 year experiments. Forage yields for 2007 will be added. Forage quality was determined in 2006, which will be discussed.
