RE: Alfalfa (Conventional and RoundUp Ready) and Red Clover Variety Trials
Alfalfa Variety Trials-Conventional and RoundUp Ready
Alfalfa trials will be established at two sites this season with RoundUp Ready Alfalfa entries planted separately from Conventional Alfalfa entries. Most sites will be on a four cutting per year schedule. A variety may be entered in any or all of the sites. To enter: fill out the form entitled WISCONSIN ALFALFA and RED CLOVER PERFORMANCE TRIALS ( Adobe format WORD format)All yield data including that from the seeding year will be sent to you. Data is published in Extension publications for both seeding and production years. A variety will appear in the Wisconsin Perennial Forage Update and newspaper supplements if the following conditions are met:
a. At least one production year from at least three sites has been harvested.
b. We have been told the variety is being marketed by the developer.
c. It has been entered in UW variety trials as commercial seed as per recommendation of the Central Alfalfa Improvement Conference.
d. For varieties to remain in the Forage Variety Update for Wisconsin once the initial trials have ended, they must be re-entered in at least two sites. For a listing of those varieties that will be dropped from the Update unless re-entered, please go to this web page
e. Seed of marketed varieties must be from a 50 lb. commercially tagged bag obtained either from dealers according to the protocol developed by the Central Alfalfa Improvement Conference or via UPS shipment. For an explanation of this protocol, please go to this web page.
A Red clover trial will be established if interest warrants. Fees for red clover are the same as for alfalfa and may be combined into one check with alfalfa entries. To enter: fill out the form entitled WISCONSIN ALFALFA and RED CLOVER PERFORMANCE TRIALS ( Adobe format WORD format)
Eligibility of Entrants: Privately developed cultivars and experimental strains will be
accepted for fee-testing by the Agronomy Department and UW Extension Service.
This excludes blends. Cultivars should be adapted to the environment occurring
cultivars of interest to
Locations of Tests: The tests will be conducted on locations in the state specified in the application forms.
Seed: Seed will be provided as follows:
Marketed Varieties: Only seed from a 50 lb. commercial bag either shipped or obtained
from dealers according to the protocol developed by the Central
Alfalfa Improvement Conference will be accepted for inclusion in the trials.
(To pick up a bag from a dealer, a voucher, the fee for each 50 lb. bag, and an
address of a dealer stocking the variety must be provided to Kevin Silveira,
We will also accept UPS shipments provided that
it is a 50 pound commercial bag with tag information indicating Variety name,
Marketed Varieties that were entered last year: There is an alternative for
those who will be entering the same commercial varieties this season as they
last season. A sufficient amount of seed
was properly stored for re-distribution this coming year. Checks are still made out to "
Experimental Varieties: Only raw, untreated seed will be accepted for inclusion in the trials. Seed should not be pre-inoculated. All seed will be inoculated with Rhizobia and (for alfalfa only) treated with Apron prior to planting.
Marketed and Experimental: Only raw, untreated seed will be accepted for inclusion in the trials. Seed should not be pre-inoculated. All seed will be inoculated with Rhizobia prior to planting.
Description of Tests:
RoundUp Ready Alfalfa entries will be planted separately from Conventional Alfalfa entries in order to conduct the appropriate weed management. Entries will be planted in replicated drilled plots, 3 x 20 feet or 4 x 15 feet. The center (depending on harvesting machine) will be harvested for yield and dry matter. Alfalfa will be harvested for three years (red clover for two years) unless stands are depleted sooner. Data on other traits, such as stand establishment and persistence, maturity, reaction to disease and insects, and rate of recovery, will be taken when appropriate.
Entries: Application for testing will be made by company designation . The company is obligated to notify Kevin Silveira if the designation is changed. The information requested on the application form is required.
Right to Reject: We reserve the right to restrict varieties. The right to restrict or reject any application is reserved if:
1. The information requested in the application is incomplete.
2. There is misrepresentation.
3. The entry fee is not paid.
4. The strain has been entered by another company.
5. The seed or application arrives late.
6. Sufficient seed is not available for trial.
7. Facilities or manpower are not available.
Fees: Commercial distribution fee is $260 per bag for new seed and $160 for last year’s bag. A fee of $600 per entry, per location, is requested for each yield test entry. If sufficient entries are not received to justify trial, the fee and seed will be returned.
Deadline for Entry: The applications, entry fee, experimental alfalfa seed and red clover seed should be in possession of the Agronomy Department by March 1.
Amount of Seed: The company will submit a minimum of 150 grams of properly labeled seed for Red Clover (commercial or experimental) and 150 grams of Alfalfa seed (experimental) per location for yield trials. (Alfalfa seed amounts are for experimental entries only)
Use of Seed: The seed will be used for testing only, and will not be used for increase, selection, or distribution by the testing station.
Publication of Results: The data will be statistically analyzed and summarized by the
Department each year. Each entrant will be furnished a report giving specific
performances as soon as data from all locations are available. A final report
will also be published and made available. The results will be published in
accordance with policies established by the Research Division, CALS, and the
