Cultivation in Ohio

Primary Uses:

Food Grain


Quinoa prefers cool soil conditions.  Germination can occur within 24 hours after planting when adequate moisture is present.  Provide a level, well-drained seedbed to avoid waterlogging.  Plant between late April and mid May to a depth of 0.5 to 1 inch.

 Seeding Rate:

0.5 to 0.75 lb/acre.  Usually doubled when soil conditions are not optimal. Transplanting in 18" rows with 18" between plants.


Maximum yields are possible when 150 to 180 lbs/acre N are available.  P applications have not shown to provide much effect compared to untreated plots.


Flea beetles, caterpillars, aphids, beet armyworm, and quinoa plant bug.  There are no pesticides cleared for use on quinoa.


Viruses found on spinach or beets have been found in quinoa fields.  Others are downy mildew, stalk rot, leaf spot, grey mold, and bacterial blight.


Harvest usually begins when the seed can barely be dented with a fingernail and plants have dried, turned a pale yellow or red color, and leaves have dropped.  A sorghum header attachment is recommended for combining quinoa.  Cylinder speed and air flow of combines are usually greatly reduced.  Smaller screens are used than with cereal grains due to the small size and lighter weight of the seed.


This is a high elevation crop which requires temperatures below 90 F during the bloom period. If you have more than 3-5 days of 90+, only sterile panicles will be produced.
