Soybean Variety Yield Tests 2012 - 2010

Soybean Variety Yield Tests 2012 - 2010

Roundup Ready varieties in Maturity Groups I and II were planted at the Aurora Research Farm in Cayuga Co., Neenan Brothers Farm at Lima in Livingston Co., and the Miner Institute at Chazy in Clinton Co. The Aurora and Lima sites, which are in central/western NY, average about 2450 growing degree days (GDD, 86-50o system) from May through September; whereas the Chazy site in Northern NY averages about 2150 GDD. All seed companies that are known to be distributing soybeans in New York were invited to enter their selections in the tests for a modest fee. The seed companies chose either two or three sites to test their varieties.

The April-May period was warm and dry in upstate NY, which allowed for timely planting at all sites. We planted Group I and Group II entries in separate tests at Aurora on 14 May, and Group I and Group II in separate tests at Lima on 24 May. At Chazy, Group I and II varieties were planted in the same test on 25 May. Each individual plot at all sites consisted of ten 20-ft. rows spaced 7 inches apart. Each entry was planted with small plot drill (6 foot wide Almaco) at seeding rates of 200,000 seeds/acre with four replications at each site. A randomized complete block experimental design was used for all tests. We used 22 fluid oz/acre of Roundup Touchdown about 5 weeks after planting for weed control at all sites. Aphid numbers and white mold incidence were low throughout the year at all sites. All varieties at all sites were monitored for phenological development beginning in late August and early September.

Yields were determined by harvesting an 18-foot section of the seven center rows (4.08 feet) of each plot at all sites with a small plot combine (Hege 140C). Plant height and lodging scores (1.0-5.0 rating with 1.0=no lodging and 5.0=complete lodging) were taken at harvest. The Group I test was harvested at Aurora on 13 September and the Group II test on 25 September. The Group I and II tests were harvested at Lima on 4 October; whereas the Group I/II test was harvested at Chazy on 25 October. The Hege plot combine does not have weighing capability so the entire plot sample was taken to the lab to determine plot weight and then sub-sampled to determine moisture. All yields were adjusted to 13% moisture. We used the ANOVA test to determine significance for yield, seed moisture, lodging score, and height. All means were separated by Fisher's protected LSD (0.05) when significance occurred.


Growing Conditions
May and June were warm months with ample rainfall (Table 1), which allowed soybeans to grow rapidly and fill-in quickly during the early vegetative period. Unfortunately, weather conditions turned exceedingly dry and warm from 20 June until 15 July at Aurora and Lima. The early Group I varieties at both sites attained the R3 stage by 15-20 July, which may have negatively impacted pod set in those varieties. Weather conditions were warm and moist until mid-August during pod and seed set for the late Group I and early Group II varieties at both sites. Weather conditions turned dry again, however, for the remainder of August, especially at the Aurora site, which coincided with seed-fill for the late Group II varieties. Consequently, the late Group II varieties generally did not yield as well as the early Group II varieties at both sites, probably because of more stress during the critical seed-fill period in late August for the Group II varieties at both sites. At the Chazy site, cooler temperatures and timely precipitation resulted in mostly stress-free conditions for soybeans in this northern location (Table 1). All Group I varieties attained the R7.0 stage (physiological maturity) by 1 September, and all Group II varieties attained the R7.0 stage by 7 September at Aurora. At Lima, the Group I varieties attained the R7.0 stage by 7 September and all Group II varieties by 15 September.

Waterloo, NY

Come join us on July 23 in Seneca County at Quinten Good's farm for a demonstration and walking tour of 16 different pre- and post-emergence treatments in soybean and 12 different treatments and combinations in corn.
  • Tall waterhemp and marestail are two weeds that are resistant to glyphosate and ALS herbicide modes of action in the WNY and Finger Lakes regions.
  • Each year the number of acres with resistant weed populations expands.
  • For herbicides to be an effective tool in weed management, we have to know what chemistries & application timings are most effective against these resistant weeds.

USDA Announces New Decision Tool for New Dairy Margin Coverage Program

WASHINGTON, April 30, 2019 ? Agriculture Secretary Sonny Perdue announced today the availability of a new web-based tool - developed in partnership with the University of Wisconsin - to help dairy producers evaluate various scenarios using different coverage levels through the new Dairy Margin Coverage (DMC) program.

The 2018 Farm Bill authorized
DMC, a voluntary risk management program that offers financial protection to dairy producers when the difference between the all milk price and the average feed cost (the margin) falls below a certain dollar amount selected by the producer. It replaces the program previously known as the Margin Protection Program for Dairy. Sign up for this USDA Farm Service Agency (FSA) program opens on June 17.

"With sign-up for the
DMC program just weeks away, we encourage producers to use this new support tool to help make decisions on participation in the program," Secretary Perdue said. "Dairy producers have faced tough challenges over the years, but the DMC program should help producers better weather the ups and downs in the industry."

The University of Wisconsin launched the decision support tool in cooperation with FSA and funded through a cooperative agreement with the USDA Office of the Chief Economist. The tool was designed to help producers determine the level of coverage under a variety of conditions that will provide them with the strongest financial safety net. It allows farmers to simplify their coverage level selection by combining operation data and other key variables to calculate coverage needs based on price projections.

The decision tool assists producers with calculating total premiums costs and administrative fees associated with participation in
DMC. It also forecasts payments that will be made during the coverage year.

The new Dairy Margin Coverage program offers very appealing options for all dairy farmers to reduce their net income risk due to volatility in milk or feed prices," said Dr. Mark Stephenson, Director of Dairy Policy Analysis, University of Wisconsin, Madison. "Higher coverage levels, monthly payments, and more flexible production coverage options are especially helpful for the sizable majority of farms who can cover much of their milk production with the new five million pound maximum for Tier 1 premiums. This program deserves the careful consideration of all dairy farmers."
