Begin Height 24" • Stop Height 6" Rotational Grazing 1 Begin Height 24" • Stop Height 6" AS6401 has a long season in the South (100 days to bloom). This extends the harvest window and allows AS6401 to be used where photoperiod sensitive hybrids are not effective. In northern regions, AS6401 will bloom at approximately 65 days. Due to its tropical genetics, AS6401 has better re-growth in wet or humid conditions.
