from Mark Sorrells, Jan 1995
To: Persons interested in the performance of small grains varieties in New
York.
Enclosed are the results of our 1994 small grains regional trials and the
cumulative summaries over the years. Because the rankings of the varieties
and lines often change from year to year, only the multiple year summaries
should be considered to be useful indicators of varietal performance in this
region. Reproduction of any table in this report must include the entire
table. The information herein is provided with the understanding that no
discrimination is intended and no endorsement by Cornell University or its
employees is implied.
Your comments and suggestions concerning this report are welcome. If you
would like additional information or do not wish to receive this report in the
future, feel free to call or write.
Sincerely,

Testing Procedures:
In 1994, the Soft White Winter Wheat, Soft Red Winter Wheat and the Spring
Oat regional trials were grown in four locations while the Hard Red Spring
Wheat, and Spring Barley regionals were grown in three locations. The
trials near Ithaca consisted of 2 replicates while those out in the state
consisted of 3 replicates. All spring barley trials had 3 replicates. All
trial plots are 6 row plots 4 meters long with 18 cm between rows. Prior
to harvest, the plots are trimmed to 3 meters and harvested with a plot
combine. Disease and lodging notes were recorded on a 0- to 9 scale with
0 being the best and 9 the poorest. All trials are planted in a randomized
complete block design and analyzed by standard ANOVA. If there are
indications of within replicate field variation a second ANOVA using a
nearest-neighbor adjustment is computed. If the coefficient of variation
is significantly reduced, those adjusted means are used for the summary.
The winter grains trials were planted between 9/20 and 10/8 and the spring
grains were planted between 4/19 and 5/4. The heavy rainfalls in March and
early April (see file Precipitation.gif) delayed planting of spring grains.
That was followed by dry weather in May which limited the yield potential
of the spring sown crops.
Acknowledgments:
Our testing program depends on being able to test new varieties in the areas
where they will be grown under actual farming conditions. We gratefully
acknowledge the farmers who have provided us with a test site for our
regional trials. Without their support we would not be able to provide
accurate, unbiased test results. Also, we thank Nate Harendeen and Jim
Capron for their excellent cooperation and support over the years.
