COMMENTS ON THE GROWING SEASON
2010 UMOPN
LACOMBE, ALBERTA
Seeding in Lacombe was normal this year, and the seed went into good moisture. Conditions remained quite 
favourable for June as well. July and August were VERY wet months, so harvest was not completed until well into 
October. Yields remained fairly high, but due to the weather more lodging and disease were noticed.
WINNIPEG, MANATOBA
Manitoba had more precipitation than the 30-year normal, but in most areas there were more than normal degree
days or corn heat units.  Excessive rains reduced yields and quality.  Rains late in the growing season prevented
timely harvesting resulting in weathering and reduction of crop quality.  Heavy Crown Rust pressure was present.
OTTAWA, ONTARIO
The yield level was very low this year due to late planting and early drought. 
URBANA, IL
Higher than average temperatures early in the growing season resulted in limited tillering. There was little 
evidence of BYDV infection. Excessive rainfall during grainfill resulted in extensive lodging.  High temperatures, 
short grain fill period and lodging reduced test weights.
WEST LAFAYETTE, IN
The seedbed was prepared for oat seeding by discing after soybean harvest in fall, 2009. Fall seedbed
preparation enabled us to seed on March 19 because heavy equipment was not needed to till the soil
prior to seeding.   Oat emergence and stand establishment were excellent.   Temperatures were below 
normal until mid April, when temperatures abruptly became above normal and remained above normal 
through oat harvest.   Fortunately, rainfall was above normal with frequent rains throughout the
growing season and through oat harvest.   The warm and rainy conditions allowed excellent oat growth 
and grain development, resulting in high grain yield and good test weight, even in later maturing oat 
lines.  The rainy and sometimes windy conditions resulted in significant lodging, although late in the 
season, so grain yield was not significantly reduced.
EAST LANSING, MI
ROSEMOUNT, MN
Seed was planted into soil with adequete moisture resulting in uniform germination, unlike previous year.  
Timely rain and moderate temperatures facilitated a good growing season as well as substantial crown rust 
infection.  A strong mid-summer storm during grain fill caused some uniform lodging and uneven maturation.
MORRIS, MN
Nursery was not reported due to major planting errors.
ITHACA, NY
The growing season was two to four degrees warmer than normal and rainfall was below average rainfall 
 with a total of 14 inches for the growing season, 2 inches below normal. 
CARRINGTON, ND
The Carrington UMOPN was planted April 21.  Good growing conditions prevailed through most of the season.  
Diseases were not a factor.
FARGO, ND
The Fargo UMOPN was planted April 12 into adequate to excess soil moisture resulting in rapid emergence 
and good stand establishment.  Good soil moisture conditions prevailed through most of the growing season.  
Thunderstorms caused lodging after heading.  Disease development was minimal and appeared to have little
 have little effect on results.
MINOT, ND
The Minot UMOPN was planted April 14.  Moisture stress occurred by mid-June, but timely rains early in July 
resulted in good plant development.  Very little disease development occurred.
BROOKINGS & WATERTOWN, SD
I didn’t combine the Watertown location due to very high fertility levels that caused excessive lodging.  I didn't
feel the yield or quality data would be a true representation of a normal production practice; therefore, in my  
opinion bad data is far worse than no data.
The Brookings location also had record rainfall; however, the nurseries were located on high ground.  Growing
conditions were excellent and disease pressure was low.
MADISON, WI
Everything was early in 2010. Planting was done on 4-15-2010. Mean temperature in April was 52.4 F with 4.5  May’s mean temperature was 60.1 F and June had a mean temperature of 68.0 F. Total rainfall for May and June combined was 13.8 inches. July and August were also hot and wet with combined rainfall of 8.9 inches, and a combined mean temperature of 72.8 F. The UEOPN was harvested on August 3rd and the UMOPN on August 16th. Although we had more than adequate rainfall, the high temperatures and disease pressure, combined with the “shortening up” of the season caused yields and bushel weights to be low. Lodging pressure was typical for the number of storms we had. Levels of CRS were moderate to high and BYDV levels were moderate.
