    In 2020, 45 corn silage hybrids representing 11 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 since the relative maturity (RM) submitted by the companies with results listed in separate tables. The Ohio test site is located in our Northwest Region at Hoytville (Wood County). The two MSU sites are in Branch and Lenawee counties, which are on the Ohio/Michigan state line.

    Silage harvest has begun in some parts of Ohio. Proper harvest timing is critical because it ensures the proper dry matter (DM) concentration required for high quality preservation, which in turn results in good animal performance and lower feed costs. The proper DM concentration is the same whether it is a beautiful, record breaking corn crop or a severely drought stressed field with short plants containing no ears. 

    The recommended ranges for silage DM are:

    Bunker: 30 to 35%

    Upright: 32 to 38%

    Sealed upright 35 to 40%

    Bag: 32 to 40%

    The primary goal of making corn silage is to preserve as many nutrients in the corn plant as possible, to produce a feed that is acceptable to cows, and to minimize any risks associated with feeding the silage.  The following are important considerations for making corn silage when growing conditions have been dry.
