COMMENTS ON THE GROWING SEASON

for the 2012 UEOPN

URBANA, IL

The season was very early and got progressively hotter and drier as the season progressed.

WEST LAFAYETTE, IN

We planted the UEOPN on March 7 and the UMOPN on March 14. Planting dates usually are around

March 20. We had an early, warm spring that was very favorable for the oats. They were able to put on

most of their growth prior to the heat and drought conditions later in June. Even the latest maturing oats

flowered on May 31 of this year and almost 2 weeks ahead of 2011. We did have good rust pressure

later in the season but the grain had very good quality.

ST. PAUL, MN

Early planting was followed by excess moisture early in the first half of the growing season.  After pollination,

hot and dry conditions prompted early harvest with very little rust development.

WASECA, MN

Moderate conditions early were followed by hot and dry conditions late in the growing season.

BROOKINGS AND BERESFORD, SD

We had good moisture at planting and with adequate moisture throughout the growing season except for

Beresford which was extremely dry.  We also got hit hard with bacterial infections at the Brookings and

Beresford locations.  With the lack of stem rust and crown rust at these locations, the data should be useful in

identifying bacterial resistance levels.

MADISON, WI

2012 started out as a very early season with much promise, after one of the warmest winters on record. Planting was done on April 6. Germination looked good with even stands. In early May a wave of leafhoppers migrated through the region and spread Aster Yellows (AY) throughout the trials at Madison and Arlington. Outlying stations were not as badly hit. Since AY is not a common disease here, it created much symptomology and growth retardation, i.e. a lack of tillering. Just as plants were rebounding from this event we got into a bad drought that lasted 6 weeks, combined with very high temperatures during late June and July. Aprils mean temperature was 47.0 F with 2.3 inches of rain. Mean temperature for May was 62.7 F and we had 2.8 inches of rainfall. High temperatures began in June, which had a mean temperature of 71.6 F with 0.87 inches of rain. July and August stayed hot with less than adequate rainfall.  July’s mean temperature was 78.3 F (13 days of highs above 90.0 F) and August had a mean temperature of 70.0 F. Total rainfall for July and August combined was 5.7 inches. The UEOPN was harvested on July 11th and the UMOPN on July 17th. The high temperatures and disease pressure caused yields and bushel weights to be low. Lodging pressure was light. Levels of CRS and BYDV were low.
