COMMENTS ON GROWING CONDITIONS

2007 UMOPN

LACOMBE, ALBERTA

The trial was planted during good conditions. However, wet conditions occurred shortly after emergence, water stressing

the trial. July was very hot with normal moisture, while August was cool and wet.

WINNIPEG, MANITOBA

The trial was planted during good conditions. However, conditions turned wet shortly after emergence, water stressing the

trial. July and August were very hot and dry.

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.

ABERDEEN, ID

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.

MORRIS & ROSEMOUNT, 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. ByJune 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.

CARRINGTON, ND

The nursery was planted April 26 into relatively dry soil, but enough soil moisture was present for uniform emergence.

The nursery received adequate rain during the first week in May and June. Very little precipitation fell during July

and temperatures were unusually warm. Little disease development occurred.

FARGO, ND

The nursery was planted into moist soil and emergence was uniform. April, May, and early June were characterized

by adequate to excessive rain accompanied by warmer than normal temperatures that resulted in more rapid than

normal plant development. Late June, July and August were extremely dry and warmer than normal. Because

of dry conditions, crown rust development was minimal.

MINOT, ND

April was a very dry month at Minot, but we obtained uniform stands in the UOPN. May was extremely wet.

June provided moderate rainfall and July and August were extremely dry with little rain. Temperatures were uusually

warm during July and August. Because of the dry conditions during July and August, Minot should be considered

a non-rust site.

ITHACA, NY

Average daily temperature was about 1 degree below normal and total precipitation was about 1 inch below normal. .

However, May precipitation was less than one third of the normal rainfall and June was also below normal resulting in poor

spring oat vegetative growth and below average grain yield. No significant disease problems

BROOKINGS, SD

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.

WATERTOWN, SD

At the Watertown location, soil moisture conditions were very wet at planting and were adequate

throughout the growing season. Cool early temperatures affected the stands of some of the hulless lines.

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 crown rust

and stem rust were low to moderate and BYDV levels were moderate to high. The season tended to favor later

maturing lines.
