- Comments:
- This premium quality Japanese variety is agronomically inferior
to California rice varieties but it has exceptional milling yields.
Seedling vigor is better than Akitakomachi but lower than most
California varieties. Slow seedling growth may increase risk of
herbicide damage and poor stand establishment. The hulls are
pubescent resulting in a quicker drydown than smooth varieties.
The straw is weak and lodging is usually severe. Low nitrogen
rates should be used, 30 to 60 lb N/acre preplant followed with a
topdressing at panicle initiation if needed (no more than 100 lbs
total. Harvest at 22% moisture or less.
