It is a popular agricultural grass and is now commonly grown for animal feed. Temperature, humidity, and rainfall all affect the length of the pollination period and when pollination begins. [4][5][6] Upon his recommendation it became a major source of hay and cattle fodder to British farmers in the mid-18th century.[7].
