The Influence of Cutting Interval on Alfalfa in the High Andes¹

Synopsis: Percentage of flowering was not a reliable guide for alfalfa harvests since plants remain vegetative throughout the year and appearance of flowers is sporadic and erratic. Clipping alfalfa when new shoots were 2 inches high resulted in high quality forage and hay yields equal to those from other cutting frequencies. Many plants had not reached apparent physiological maturity when clipped every 5 or 7 weeks, but many leaves were lost when cutting was delayed longer.
