November/December 2021 - 26

After a series of heavy rainstorms
in the spring, summer growing
conditions
became
exceptionally
warm. This resulted in lower sets but
had a negligible effect on seed quality.
Summer field inspections and virus
testing indicate an increase in PVY
incidence across the state.
A total of 317 lots will be sent to the
winter grow-out at Twin Bridge Farm
in Waialua, Hawaii. The remaining
lots either did not pass summer field
inspections/virus testing or will not be
recertified.

acres inspected. We had a decent
spring season leading to timely
planting in most areas of the state.
Since the beginning of July, many
areas of New York have been above
average in rainfall. The rains have led
to above average yields, a 10 to 25%
increase. Tubers are average size to
larger than usual and quality has been
good. Harvest was nearly done as of
Oct. 20, despite scattered showers
throughout September and October.
Lamoka
represents
the largest
acreage entered for certification in
New York with Lady Liberty (NY152)
and Waneta, the next highest acreages.
We are currently preparing samples
for our winter grow out in Waialua,
Hawaii in November.

NORTH DAKOTA
Despite record-setting drought
statistics for North Dakota, seed
potato growers were still able to
harvest a crop. The drought was
the worst on record since 1988, and
then since the dust bowl years. While
record highs for temperature were
not broken in given days, the number
of consecutive days of higher than
average
temperatures
contributed
greatly to the drought intensity.
This 2021 crop was affected by the
dry 2020 fall, followed by a winter
with relatively little moisture. Our
dryland growers were forced to plant
into a moisture deficit soil. And after
that, there was limited moisture from
scattered localized showers. The
consistent high temperatures and
smoky overcast from northern and
western fires affected yields in both
dryland and irrigated potatoes.

rains just prior to and during harvest
helped condition the dryland soils
for a smoother harvest. Growers still
had to deal with dirt clumps. Quality
appears to be good, but the size
profile is reduced due to the summer
heat and moisture stress. Harvested
quantity generally is 66% of average
on dryland acres, and maybe 90% on
irrigated acreage. Processing varieties
yielded less than average with a
smaller profile. Seed potatoes will be
limited this year.
