2014 MICHIGAN CORN PERFORMANCE TRIALS

Entry forms are available for the 2014 Michigan Corn Performance Trials. If you plan to enter please send a reply ASAP, this will hold your spot in the trials. Entries are due by March 15, 2014. Upon completion return the entry form to us and print one copy for your files. If you have more than one Brand Name per company, submit separate entry forms for each Brand. Entry into the trials is for the implied purpose of publishing yield results of hybrids under their commercially released name. Experimental hybrids listed under a Brand name are accepted.

The objective of the Michigan Corn Performance Trials is to provide unbiased performance data on corn hybrids in scientifically conducted trials throughout Michigan. Participation by all seed companies marketing seed corn in Michigan is encouraged. This data provides Michigan farmers with a good representation of available hybrids. Your participation in providing voluntary entries is appreciated.

PROCEDURES

Hybrids are divided by relative maturity as listed on the entry form into an early or late maturity group in Zones 1, 2, and 3. Seed of each entry is counted, packaged, and arranged in a randomized complete block design with four replications. Four row plots, 22 feet long, are planted for all plots using a vacuum plate planter. Harvest data will be taken from the center two rows. Hybrids are tested at all locations within each zone entered. Hybrid identifications are coded throughout the season and decoded only after all data has been processed.

Stand counts are taken before corn is knee high, lodging counts are taken at harvest. Plots are harvested mechanically. Data on yield, moisture content at harvest, test weight at harvest moisture, lodging, and percent stand are processed on MSU computers. Silage tests are harvested uniformly as close to 65% dry matter as possible. Silage results present the percent dry matter of each hybrid and dry weight as tons per acre. Quality analyses for silage are predicted via near infrared reflectance (NIR), milk production is estimated using MILK2006.

A pre-publication copy of the data is sent to all participating companies. Final results are published as an extension bulletin E-431 “2014 Michigan Corn Hybrids Compared.” One, and two year averages, based on data from 2014 and 2013 will be summarized for each zone. Complete tables with two year averages for each individual location are available at our web site: https://varietytrials.msu.edu. Due to the fast turnover of hybrids three year averages will not be published.

Zonal boundaries are an arbitrary designation based on thirty year average Growing Degree Day heat units for (May 1 to Sept 30). Estimates are 2500-2800 in Zone 1, 2400-2600 in Zone 2, 2200-2400 in Zone 3, 1900-2100 in Zone 4, and 1700-1900 in Zone 5, enter hybrids accordingly. Many hybrids are adapted to more than one zone. An early season hybrid in one zone may be a late season hybrid in another. The maturity splits between early and late trials in 2014 will be 107-108 Day for Zone 1, 101-102 Day for Zone 2, and 96-97 Day in Zone 3 and 98-99 Day in the Conventional trial. The maturity split for silage will be: Zone 1 110-111 day, Zone 2-3 104-105 day. Silage trials in Zone 4 and 5 will have only one maturity grouping.

LOCATIONS AND FEES

Fees will remain static for 2014. Three county trials are used in each zone and are identified below. Grain trials are $275 per entry for Zones 1, 2, 3 and 4. Zone 5 is $132 with two locations. The Conventional trial is $275 with entries in Ingham, Montcalm and Saginaw Counties. Menominee County hybrids grouped with Zone 4 will be designated (Late) and while hybrids grouped with Zone 5 will be designated as (Early). Fees for the silage trials with 3 locations are $440 per entry for Zone 1, and Zone 2/3 trial. The Zone 4 trial is $385. Zone 5 with 3 locations is $280.

Please be sure to indicate the relative maturity for each hybrid on your entry form. List all hybrid traits and/or transgenics by the number listed in the code appendix. If there are any marketing restrictions check the appropriate box. Be sure Company name, Brand name and Hybrid number are listed on the entry form as they should appear in the bulletin. Hybrids entered in multiple years must keep identical hybrid numbers year to year.

Entry forms and fees need to be submitted by March 15, 2014 so field designs can be generated. Please make checks payable to MICHIGAN STATE UNIVERSITY and send to Bill Widdicombe’s attention at the address listed below. Please check that envelopes are addressed correctly to guarantee proper delivery. Note address change below:

“Window” checks need to contain the same complete address to avoid any confusion. If the name and department are not on the check they can be miss directed elsewhere on campus.

SEED AND SHIPPING INSTRUCTIONS: Seed should follow the March 15 deadline shortly so we have time for packaging. If seed shipment is delayed for any reason (winter nurseries, etc.) please make appropriate substitutions.

We need three pounds of seed for each zone in which a hybrid is entered (two zones = six pounds, etc.). Please, submit only BULK SAMPLES (one bag per hybrid). We recommend you send us MEDIUM flat or round seed sizes for optimum planting accuracy. Please forward this shipping information to the proper individuals for shipping. We request that seed be taken from warehouse lots whenever possible. Please join us in presenting the most unbiased information possible. Seed treatment product(s) must be identified and followed with a MSDS form for each product(s).

Please address seed shipments as follows:

Again please take the time to respond ASAP of your intentions for entry into the trials. This will hold space for you in the trials and it helps us to know as early as possible as to who will be entering the 2014 trials.

We invite your continued cooperation in this program. Participation of all companies marketing seed corn in Michigan is vital to the success of these trials. If at any time you wish to contact us please do not hesitate.
