SF Narrikup

sub-clover

SF Narrikup is a very vigorous mid-late season subterraneum clover (ssp. subterraneum), flowering approximately 126 days from an early May sowing in Perth.

It is best suited to well-drained, moderately acid (pHCa 4.5 – 6.5) soils in areas of southern Australia with approximately 500–700 mm mean annual rainfall and where the growing season extends to mid November.

Emerging seedlings of SF Narrikup suffer less damage from Red-Legged Earth Mite (Halotydeus destructor) than older subterraneum clovers. This is most evident at low to moderate RLEM densities. Work by CSIRO has demonstrated that RLEM fed less and produce less progeny on subterraneum clovers with cotyledon resistance.

A particular strength of SF Narrikup is its high winter production, driven by strong seedling regeneration densities, which may in part be attributable to its reduced cotyledon susceptibility to RLEM at low to moderate mite densities.
