NY Corn Silage Hybrid Tests 2012-2010

NY Corn Silage Hybrid Tests 2012-2010


We planted all hybrids with a 2-row plot planter at 36,000 plants/acre to achieve harvest populations of 32,000-34,000 plants/acre. The Aurora site was planted on 20 April, the Harford site on 30 April, and the Groveland Station site on 3 May. All hybrids were grouped within a 5-day RM (i.e. 91-95 day RM, 96-100, etc.), and planted in a randomized complete block design with four replications. Each individual plot consisted of two 20-ft. rows spaced 30 inches apart. Each individual plot received about 250 lbs/acre of 10-20-20 at planting. The Aurora site, which followed soybeans, received about 140 lbs N/acre of side-dressed N at the 4 to 5-leaf (V4 to V5) stage. The other two sites were well-manured dairy sites, which were 1 or 2 years removed from
perennial forages, so they received no side-dressed N. We used preemergence/postmergence herbicides and hand-weeding to control weeds.

Both rows, trimmed back to an 18-foot length, were harvested for silage yield with a retrofitted 3-row New Holland Chopper with a platform and a weigh-basket, mounted on load cells. The goal was to harvest all hybrids in the 65% moisture range (plus/minus 3%), but some of the early-season hybrids were drier than planned, despite harvesting the Aurora and Harford sites in August. The Aurora site was harvested on two dates: 85-99 day RM groups on 22 August when hybrids in the three maturity groups ranged from about 62 to 65% moisture. The 96-115 day RM groups were harvested on 27 August when hybrids in the three maturity groups ranged from about 61 to 64%. We harvested all maturity groups at the Harford site on 30 August when moistures ranged from about 60% for the 84-90 RM group to about 66% for the 101-105 RM group. We harvested the Sparta Farms site in Livingston Co. on 5 September. Moisture ranged from about 60% for the 85-95 RM group and then increase by about 2 percentage points with each 5 day RM increase up to 68% moisture for the 111-115 day RM.

An approximate 10,000 g well-mixed sample was originally collected from the chopper after harvest of each plot. The 10,000 g sample was then ground further in the field with a chipper-shredder. An approximate 700 g sub-sample was then weighed and recorded with a gram-scale wired to a computer in the field and refrigerated in a generator-powered freezer (samples were kept cool but not frozen). At the end of each day, the samples were brought back to a Cornell Research Farm for drying. The samples were dried at 140o F in a forced air drier to constant moisture and then weighed to determine moisture content of each sample.

Dry samples were ground to pass a 1 mm screen using a Wiley mill. Samples were processed and analyzed by Cumberland Valley Analytical Services, Inc. Samples were analyzed by wet chemistry for neutral detergent fiber (NDF), according to procedures by Van Soest et al. (1991). Samples were incubated for 30 hours at 39oF in a buffered rumen fluid, according to procedures by Van Soest and Robertson (1980) using a flask system and Van Soest buffer. Following fermentation, residues were analyzed for NDF by wet chemistry to determine 30-hour NDF digestibility (NDFD). The NDF digestibility was calculated as ([1-NDF residue/initial NDF] x 100). Crude protein (CP), starch, ether extract, and ash were determined using NIRS. Milk per ton and milk per acre were then calculated using the Milk2006 spreadsheet program (Tables 2-5). Data were analyzed using the PROC GLM procedure of SAS. The LSD values for separating hybrid means were generated at the P = 0.10 level.

Upcoming Events

Beginning Farmer/Hobby Farmer Workshop $5/pp, class size is limited, so pre-register by April 15th!

April 27, 2019

This hands-on workshop is for beginning or part-time farmers who would like to improve their farm machinery skills, learn to properly and safely maintain their equipment to protect their investment. If you have been thinking about buying a tractor, new or used, two-wheel or four-wheel drive, compact or utility or more come join us. Topics include: selecting the right size/type tractor for the job; basic maintenance; staying safe around tractors and equipment; attaching implements properly; and information about ROPS and SMV's. There will be time for questions.

Pre-registration requested by April 15, 2019 email Amy with your name, address, and phone number or call 585-394-3977 x 429.
Fee: $5.00/person. Class size is limited.

2019 Pastured Poultry Seminar, lunch included so please register by May 10th! $25/person

May 18, 2019
Registration begins at 8:00 a.m.w/ coffee & donuts with the Program running from 9:00 a.m. - 5 p. m.
Attica, NY

The main speaker this year is Eli Reiff of Mifflinburg Pennsylvania. Eli raises broilers, turkeys, sheep, and beef, all on pasture. Topics to be covered will include the pasture, feed and nutrition, marketing, costs, and much more. As we grow as farm operators and get bigger, we may not pay as much attention to the basics as we should. So those areas are where we will start, and then expand to cover the group's interests.

Mike Badger, Director of the American Pastured Poultry Producers Association will also be available for a round-table discussion. Plans are to have representatives from Farm Bureau, NYCAMH for farm health and safety, Wyoming County Chamber of Commerce, and Cornell Cooperative Extension of Wyoming County, as well as others.

USDA Announces January Income over Feed Cost Margin Triggers First 2019 Dairy Sa

WASHINGTON, March 6, 2019 ? The U.S. Department of Agriculture's Farm Service Agency (FSA) announced this week that the January 2019 income over feed cost margin was $7.99 per hundredweight, triggering the first payment for eligible dairy producers who purchase the appropriate level of coverage under the new but yet-to-be established Dairy Margin Coverage (DMC) program.

DMC, which replaces the Margin Protection Program for Dairy, is a voluntary risk management program for dairy producers that was authorized by the 2018 Farm Bill. DMC offers 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.

Agriculture Secretary Sonny Perdue announced last week that sign up for 
DMC will open by mid-June of this year. At the time of sign up, producers who elect a DMC coverage level between $8.00 and $9.50 would be eligible for a payment for January 2019.

For example, a dairy operation with an established production history of 3 million pounds (30,000 cwt.) that elects the $9.50 coverage level for 50 percent of its production could potentially be eligible to receive $1,887.50 for January.

Sample calculation:
$9.50 - $7.99 margin = $1.51 difference
$1.51 times 50 percent of production times 2,500 cwt. (30,000 cwt./12) = $1,887.50

The calculated annual premium for coverage at $9.50 on 50 percent of a 3-million-pound production history for this example would be $2,250.

Sample calculation:
3,000,000 times 50 percent = 1,500,000/100 = 15,000 cwt. times 0.150 premium fee = $2,250

Operations making a one-time election to participate in DMC through 2023 are eligible to receive a 25 percent discount on their premium for the existing margin coverage rates.

"Congress created the Dairy Margin Coverage program to provide an important financial safety net for dairy producers, helping them weather shifting milk and feed prices," FSA Administrator Richard Fordyce said. "This program builds on the previous Margin Protection Program for Dairy, carrying forward many of the program upgrades made last year based on feedback from producers. We're working diligently to implement the DMC program and other FSA programs authorized by the 2018 Farm Bill."
