2014 Preliminary Data:  UI Soft White Spring and Hard Spring Wheat Trials

The preliminary data from the soft white spring and hard spring wheat trials from the all north Idaho locations in 2014 (Craigmont, Genesee, Moscow, Bonners Ferry) is now available.  Stripe rust was not observed at any of the locations with the exception of Bonners Ferry.  However, fungicide applications were made to manage the disease and minimal symptoms were observed.  Overall, yields were below to near average.  There was less variability and drought stress observed in the spring wheat plots than was observed for winter wheat.

Craigmont:

This trial was seeded on April 21 and harvested on September 2.

Genesee:

This trial was seeded on April 16 and harvested on August 8.  No lodging observed at this location.

Moscow:

This trial was seeded on May 3 and harvested on August 22.  No lodging observed at this location.

Bonners Ferry:

This trial was seeded on April 30 and harvested on August 28.  Glee, which had the highest percent lodging at this location, also had the greatest variability, ranging from 5 to 60%.

2014 Preliminary Data:  UI Spring Pea Variety Trials

Preliminary data from the spring pea variety trials at north Idaho locations in 2014 (Craigmont, Genesee, Moscow).  Precipitation was below normal in the spring resulting in drought stress to all legume sites.  In addition, scattered hail and wind storms resulted in damage to the pea plots.  This is likely one of the primary reasons for the high cv’s for yield at Craigmont and Moscow.  The most significant damage was observed at the Craigmont site.  The cooperator at this site reported a 30% loss to the surrounding lentils.

Craigmont:

This trial was seeded on May 14 and harvested on September 5.  Seeding at this location was delayed due to the order that this field was prepared by the cooperator and wet conditions at the plot site.

Genesee:

This trial was direct seeded on May 1 and harvested on August 18.

Moscow:

This trial was direct seeded on May 2 and harvested on August 7.

2014 Preliminary Data:  UI Lentil Variety Trials

Preliminary data from the lentil variety trials at north Idaho locations in 2014 (Craigmont, Genesee, Kambitsch, Moscow).  Precipitation was below normal in the spring resulting in drought stress to all legume sites.  In addition, scattered hail and wind storms resulted in damage to most lentil plots.  The most significant damage was observed at the Craigmont site.  The cooperator at this site reported a 30% loss to the surrounding lentils.

Craigmont:

This trial was seeded on May 14 and harvested on September 5.  Seeding at this location was delayed due to the order that this field was prepared by the cooperator and wet conditions at the plot site.

Genesee (south of Genesee along the rim overlooking the Lewis/Clark valley):

This trial was direct seeded on May 1 and harvested on August 18.

Genesee (University of Idaho Kambitsch Research Farm):

This trial was seeded on May 7 and harvested on August 8.

Moscow:

This trial was seeded on May 3 and harvested on September 8.  Harvest was delayed because selected varieties matured late.  Due to the delay, there was shattering at this location resulting in reduced yields and high cv’s.

______
2014 Preliminary Data:  UI Chickpea Variety Trials

Preliminary data from the chickpea variety trials at north Idaho locations in 2014 (Craigmont, Genesee, Moscow).  Precipitation was below normal in the spring resulting in drought stress to all legume sites.  As a result, the yield at all three locations is below average.  In addition, scattered hail and wind storms resulted in damage to several of the legume trial sites, although the impact on the chickpeas was much lower than on pea and lentil.

Craigmont:

This trial was seeded on May 14 and harvested on September 5.  Seeding at this location was delayed due to the order that this field was prepared by the cooperator and wet conditions at the plot site.

Genesee:

This trial was direct seeded on May 1 and harvested on September 8.

Moscow:

This trial was direct seeded on May 3 and harvested on September 8.

2014 Preliminary Data:  UI Soft White Winter and Hard Winter Wheat Trials

Soft White Winter and Hard Winter Wheat Trials — Lewiston/Tammany site

This trial was seeded on October 11, 2013 and harvested on July 15, 2014.  Fertility included 100-10-0-10 (N-P-K-S) applied prior to planting to both soft white and hard wheat sites.  In the spring, the hard wheat was topdressed with an additional 40# nitrogen.  This site did not have any stripe rust or other obvious disease problems.  However, the site suffered from significant drought stress which is evident in the current year yields being substantially lower than the 2- and 3-year averages.  Prior to harvest, nearby cattle escaped into the plot, causing damage to some of the plots.  Therefore, yield data for 12 plots was removed, including all four Cara plots which were preferentially grazed.

Soft White Winter and Hard Winter Wheat Trials–Genesee/Rim area

This trial was seeded on October 18, 2013, and harvested on July 30, 2014.  Fertility included 135-20-20-10 (N-P-K-S) applied just prior to planting and a spring topdress of 40# nitrogen.  Stripe rust and other disease pressure was low at this location.  In addition, this site escaped frost damage which was observed at several other north Idaho winter wheat variety testing sites.

Soft White Winter and Hard Winter Wheat Trials–University of Idaho Kambitsch Research Farm northwest of Genesee

This trial was seeded on 10/24/13 and harvested on 8/1/14.  Fertility included 100-10-0-20 (N-P-K-S) applied just prior to planting to both soft white and hard wheat sites.  In the spring, the hard wheat was topdressed with an additional 40# nitrogen.  Stripe rust was not observed at this location.  However, this site suffered from moderate drought stress and Fusarium crown rot was present across the plot.  In addition, some frost damage was observed from a cold snap on May 12th.

Soft White Winter and Hard Winter Wheat Trials–Nezperce

This trial was seeded on October 11, 2013 and harvested on August 19, 2014.  This site did not have any stripe rust or other obvious disease problems.  However, the site suffered from a combination of significant drought stress and frost damage from a cold snap on May 12th.  Most varieties had frost damage on the upper 1-3 cm of the heads and damage ranged from 0 to 73% of the heads in a given plot impacted (average of 37% for soft white and 23% for hard).  However, there was not an obvious correlation between frost damage and yield.  Due to the impact of drought and frost damage, yields were highly variable across the trial, resulting in high CVs for yield and plant height.

Note that UI/WSU Huffman has been corrected in this summary. It was incorrectly referred to as UI/LCS Huffman in previous summaries.
