COMMENTS ON THE GROWING SEASON
2007 UEOPN
AMES, IA
The nurseries were planted in mid April.  Cold weather after planting delayed germination.  Warmer weather in May
and June hastening plant growth.  This, along with dry weather in June reduced yields.  Test weights were near
normal.  Disease was not a problem this year.

URBANA, IL
Plots planted somewhat later than optimal.  Hot dry conditions early, therefore oats did not tiller much and were
short.  Hot dry conditions also reduced grain fill.  BYDV significantly reduced yields.  Fertilizer: 80 lbs N/A, P and K
ok by soil test.  Herbicide: Buctril 1pt/A.
WEST LAFAYETTE, IN
Early spring weather conditions were excellent for oats: soil was dry enough for timely seeding on March 18. Oats
emerged on April 1. At the two-leaf growth stage we had temperatures in the low 20sF causing freezing of the
above-ground tissues, but the oats recovered.  Temperatures remained cool throughout April. Thus, plants were
short, about 2/3 of normal plant height, and panicles were smaller than normal.
Temperature and soil moisture were good for oat growth until early June, just after flowering. During June and early
July during grain fill, temperatures were warm and soil moisture became limiting, limiting yield and test weight
somewhat.  In general, a below-average season for oat production.
EAST LANSING, MI
Our weather turned warm rather early this year.  Mild disease pressure with a little BYD.
ROSEMOUNT & WASECA, MN
Planting was delayed somewhat because of excess moisture early. Planting progress caught up in early May but
not emergence. By mid-May emergence had caught up and jointing was slightly ahead of average because of
elevated temperatures.  By early June jointing was significantly ahead, but no heading occurred until June 9.
Moisture was just beginning to diminish, especially in the Morris area and south to the Iowa border. By June 24
heading had progressed more than normal and moisture was getting to be generally in short supply. Temperatures
were usually above normal and continued warmer in much of the state for most of the remainder of June, July and
most of August. By July the crop was turning ripe ahead of 5-yr average and maturity continued ahead of average
for the rest of the season. Half of the crop was harvested before the end of July and most of it was completed by
mid-August.  Crown rust was difficult to find and lodging was minimal.
BERESFORD & BROOKINGS, SD
At the Beresford location, the soil moisture conditions were excessive up to midseason and adequate the latter
part of the season. Temperatures were cool early; however, as the growing season progressed they became
extremely hot.  Crown rust and stem rust infections were severe late in the season.

At the Brookings location, soil moisture was excessive at planting; however, as the growing season progressed
soil moisture conditions deteriorated to dry.  Temperatures were cool early; however, as the growing season
progressed, the average temperatures were above normal.  Disease and lodging were non-existent except in the
buckthorn nursery.
MADISON, WI
Planting was done on 4-21-07, which was somewhat late due to much rain and cold temperatures. Mean
temperature in April was 44.8 F with 20 days that had measurable rainfall. Total rainfall for April was 4.9 inches.
Once planting was finished these conditions favored good germination. May and June were hot and dry with only
one day of rain greater than an inch. Total rainfall for May and June combined was 4.6 inches. Harvest came early
with the UEOPN on July 17 and the UMOPN on July 26. All nurseries were 100% standing at harvest. Levels of
favor later crown rust and stem rust were low to moderate and BYDV  levels were moderate to high. The season
tended to maturing lines.
