2017 Northwest Ohio Corn Silage Test

In 2017, 50 corn silage hybrids representing 15 commercial brands were evaluated in a joint trial with Michigan State University (MSU). One Ohio location is combined with Michigan's two southern (Zone 1) silage locations. The trials were divided into two maturity groups designated early and late on the basis of the relative maturity (RM) submitted by the companies with results listed in separate tables. The Ohio test site was located in our 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 2017 locations are treated as one region. The plots were planted with 4-row air type planters and maintained by each respective state utilizing 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 Spectroscopy (NIRS) analysis was performed by MSU using their current procedures. Silage 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).
