COLUMBUS — In 2016, 47 corn silage hybrids representing 16 commercial brands were evaluated in a joint trial with Michigan State University.

One Ohio location is combined with Michigan’s two southern (Zone 1) silage locations. The Ohio test site was located in the Northwest Region at Hoytville (Wood County). The two MSU sites were located in Branch and Lenawee counties, which are on the Ohio/Michigan state line.

The test results from the three 2016 locations are treated as one region. The plots were planted with Almaco precision 4-row air planters and maintained by each respective state with standard production practices.

The center two rows were harvested using MSU’s New Holland T6.175 tractor which powered a two-row Champion C1200 Kemper forage harvester with a rear mounted Haldrup M-63 Weigh system.

Silage tests were harvested uniformly as close to half milk line as possible. Near Infrared Reflectance (NIR) Quality Analysis was performed by MSU utilizing the NIRS Consortium calibration established for silage quality.

Results present the percent dry matter of each hybrid plus green weight and dry weight as tons per acre. Other data presented include percent stand, the percentage of in vitro digestible dry matter, acid detergent fiber, neutral detergent fiber, neutral detergent fiber digestibility, crude protein and starch.

Milk production in pounds per ton and pounds per acre were estimated using MILK2006 (UW-Madison Dairy Science Department). A complete summary of the Ohio results will be available online at: www.oardc.ohio-state.edu/silagetrials.
