Arrowleaf Clover // Trifolium vesiculosum
Arrotas was developed for Tasmanian producers to take advantage of Tasmania’s long growing season.
Arrotas (at lat. 42’) flowers 29 days later than the next variety Zulu, 31 days later than Seelu and Zulu 11 and 43 days later than Cefalu.
With adequate moisture Arrotas will provide an extra four weeks of high quality feed compared to any other variety of Arrowleaf clover available in Australia
Assuming growth rates of Arrotas are a conservative 70kg DM per day (Growth rates of 135 kgDM/day have been recorded for Arrotas ) over this four week period Arrotas will provide an extra 2t/ha in dry matter (DM) compared to other Arrowleaf clovers. Valuing pasture at $60 per tonne this equals an extra return of $120 per hectare simply by choosing the later maturing variety Arrotas.
Arrotas! The only green plant in mid summer at the Uplands Sheep Station in Northern Tasmania.
