| COMMENTS ON GROWING CONDITIONS | ||||||||
| 2005 UMOPN | ||||||||
| LACOMBE, ALBERTA – n/a | ||||||||
| OTTAWA, ONTARIO | ||||||||
| Crop Rotation -1st previous was clover | ||||||||
| -2nd previous was beans | ||||||||
| Soil Type - uniform clay / loam | ||||||||
| Planting date was April 18th. Right after planting we had 2-2.5 weeks of cold dry weather | ||||||||
| (well below normal). This delayed emergence. | ||||||||
| The yield trials were sprayed with Buctril M at the four-leaf stage. Weeds present at that time | ||||||||
| were mainly volunteer clover from last year as well as a few other broad leafs such as lamb's | ||||||||
| quarters and sow thistle, which we did not kill as well as we hoped in some areas. | ||||||||
| The remainder of the growing season was hot and humid with just enough rain. Some late | ||||||||
| season storms accounted for some of the lodging. | ||||||||
| Diseases - Septoria hit us harder and earlier than normal (by that I mean we don't usually have | ||||||||
| enough to rate, but we rated it this year, at least the plots with problems. Rust on the other hand | ||||||||
| came later, shortly after heading, but I'm not too sure if it affected yields (we did get a good | ||||||||
| rating). | ||||||||
| WINNIPEG, MANITOBA | ||||||||
| The nursery wasn't harvested due to extremely wet conditions. Unfortunately the Glenlea oat | ||||||||
| disease nursery was flooded out early this spring. As well, the Glenlea yield trial was lost in the | ||||||||
| early summer due to excessive rain. | ||||||||
| AMES, IA | ||||||||
| The nurseries were planted early because of a mild and dry winter. Warm weather continued | ||||||||
| during the growing season along with adequate moisture resulting in excellent yields and test | ||||||||
| weights. Disease was not a problem in 2005. | ||||||||
| ABERDEEN, ID – n/a | ||||||||
| URBANA, IL | ||||||||
| Above average temperatures with below normal soil moisture. Heat and drought during grain fill | ||||||||
| reduced yields and test weights. Very little disease in yield plots. | ||||||||
| W. LAFAYETTE, IN | ||||||||
| We were able to seed very early, oats emerged uniformly and the growing conditions were | ||||||||
| excellent (cool and ample moisture) through 20 June. The cool nights likely resulted in the oats | ||||||||
| being shorter than normal, and there was essentially no lodging, but the oats tillered well | ||||||||
| 4 | ||||||||
| with large panicles--pointing to a record yield. Then temperatures became very warm and no rain | ||||||||
| until after harvest on July 15, with significant soil moisture stress after July 1. Grain fill was | ||||||||
| better than expected, although test weights were reduced. | ||||||||
| EAST LANSING, MI – n/a | ||||||||
| MORRIS, MN | ||||||||
| Season began wetter and warmer than normal, with some delay in field planting. May was | ||||||||
| cooler and wetter than normal. Early in June there was a heavy rain causing standing water in the | ||||||||
| plot area. Soil moisture continued in excess for the rest of the season, but elevating temperatures | ||||||||
| prevented a major crown rust epidemic. | ||||||||
| ROSEMOUNT, MN | ||||||||
| Season started warmer but with normal moisture, with some delay in field planting. Plot | ||||||||
| planting date was average (mid-April). Weather was very favorable for both plant and crown | ||||||||
| rust development until late into June. Temperatures were below normal in mid-May, but soil | ||||||||
| moisture was adequate. Beginning in early July, temperatures warmed considerably, slowing | ||||||||
| rust development, speeding crop development, and interfering with normal grain fill. Season | ||||||||
| ended with major crown rust epidemic and poor graining-filling conditions. | ||||||||
| FARGO, ND | ||||||||
| The Fargo nursery was planted into cold soil with adequate moisture. Emergence was uniform | ||||||||
| and adequate to excess soil moisture was available through most of the season. The air | ||||||||
| temperature fell to 25o F April 22 and development of plants was delayed. Warm temperatures | ||||||||
| prevailed during grain fill, but adequate soil moisture prevented excessive plant stress. Crown | ||||||||
| rust developed late in the season and did not appear to affect any but the most susceptible | ||||||||
| genotypes. | ||||||||
| CARRINGTON, ND –n/a | ||||||||
| MINOT, ND | ||||||||
| Conditions were relatively cool and dry during the early part of the growing season. Rain | ||||||||
| occurred at an opportune time to allow good grain filling. Crown rust developed late in the | ||||||||
| season and did not seem to affect performance of lines. Thunderstorms caused severe lodging | ||||||||
| prior to grain fill in some plots. | ||||||||
| ITHACA, NY | ||||||||
| Timely planting was important for spring grains. Temperatures were above normal except for | ||||||||
| May. Precipitation was erratic with excessive rainfall in April and June and drought conditions | ||||||||
| 5 | ||||||||
| in May and July. However, over the growing season, the mean temperature was only 0.5 degrees | ||||||||
| F above normal and precipitation was 0.67 inches below normal. | ||||||||
| BROOKINGS, SD | ||||||||
| At the Brookings location, soil moisture conditions were adequate at planting and throughout the | ||||||||
| growing season. Temperatures were extremely cool early; however, as the growing season | ||||||||
| progressed growing degree units exceeded the long term average. Crown rust infections caused | ||||||||
| significant yield losses for moderately susceptible and susceptible varieties and lines. The | ||||||||
| growing season tended to favor later maturing varieties and lines. | ||||||||
| WATERTOWN, SD | ||||||||
| At the Watertown location, soil moisture was excessive at planting; however, as the growing | ||||||||
| season progressed soil moisture conditions deteriorated to dry. Temperatures were extremely | ||||||||
| cool early; however, as the growing season progressed growing degree units exceeded the long | ||||||||
| term average. Crown rust infections caused significant yield losses for moderately susceptible | ||||||||
| and susceptible varieties and lines. Lodging was observed early in the growing season and | ||||||||
| increased as the season progressed. Severity depended on landscape. | ||||||||
| MADISON, WI | ||||||||
| Planting was done at normal time into an excellent seedbed. Decent rainfall and cooler | ||||||||
| temperatures during the early growing season led to good germination, even stands, and much | ||||||||
| tillering. Then it turned very hot and dry with almost no additional rainfall recorded through | ||||||||
| harvest, except for severe storms on July 20th and 21st that flattened the nursery. Even so, yields | ||||||||
| were good and test weights were acceptable. Again, for the third year in a row, almost no crown | ||||||||
| rust was observed, and levels of stem rust and BYDV were very light and widely scattered in the | ||||||||
| nursery. | ||||||||
