Corn Silage C.C. Sheaffer, P.R. Peterson and D.R. Swanson Varietal Trials Results, January 007 The Minnesota Hybrid Corn Silage Evaluation Program evaluates the silage potential of corn hybrids in Minnesota. The goal of the program is to provide unbiased forage yield and quality information for educational and marketing programs. The program is financed in part by entry fees from private seed companies that chose to enter hybrids for testing; they are listed in this publication. Results presented are from corn silage performance trials in regions of extensive corn silage use: southeastern, central and west-central Minnesota. The locations are in important dairy regions. Test Sites Silage hybrids entered in the southeast or central region trials were tested at two sites within each region. Hybrids entered in the westcentral region were tested at one site. Sites within regions were as follows: Southeast Dairy Region: La Crescent (Houston County) Potsdam (Olmsted County) Central Dairy Region: Paynesville (Stearns County) Melrose (Stearns County) West-Central Dairy Region: Ottertail, MN (Otter Tail County) Test Procedure (Southeast and Central) Design: Plots were established at La Crescent, Potsdam, Paynesville and Melrose in randomized complete block designs with four replications. Hybrids were planted at,000 seeds per acre with 0-inch row spacing on April 7 and 8 at the SE sites (La Crescent and Potsdam) and May 4 and 9 at the Central sites (Paynesville and Melrose). Plant nutrients as manure or inorganic fertilizer were applied according to University of Minnesota recommendation. Cultivation and herbicides applied by University of Minnesota recommendation were used to control weeds. Harvesting: Plots were harvested and whole-plant herbage sampled for dry matter and forage quality at each site. Each test site was harvested when the average whole-plant moisture across entries was estimated to be 65%. In 006, harvest dates at La Crescent, Potsdam, Melrose and Paynesville were September 5, September, September 7 and September 5, respectively. (West-Central) Design: Plots were established May near Ottertail under centerpivot irrigation in a randomized complete block design with three replications. Hybrids were planted at a 0,800 seeds per acre with 0- inch row spacing. Fertilizer was applied at a pre-plant rate of 5 tons dry manure per acre. Pre-emergent herbicide was applied to control weeds. Harvesting: Plots were harvested and whole-plant herbage sampled for yield and forage quality on September 5. Companies participating in 006 hybrid corn silage performance trials.

Results Provided Tables -5 summarize hybrid yield and forage quality results from La Crescent, Potsdam, Paynesville, Melrose and Ottertail, respectively. Moisture content, whole-plant dry matter (DM) yield and silage yield are listed, and hybrids are ranked in descending order of milk yield per acre (Milk Yield, lb/acre). In 006 drought conditions at Melrose resulted in lower yields and uneven grain development at that site, but had little effect at the Paynesville site. Whole-plant forage quality traits listed include crude protein (CP), neutral detergent fiber (NDF), 48- hour in vitro digestibility (IVD), 48- hour neutral detergent fiber digestibility (NDFD), and starch concentration. With the exception of NDFD, all forage quality traits are expressed as a percent of dry matter. NDFD is expressed as a percent of NDF. Milk production potentials per ton (lb milk/ton forage) and per acre (lb milk/acre forage) of forage were calculated using the new spreadsheet MILK006 developed by the University of Wisconsin. MILK006 approximates animal performance based on a standard cow weight and milk production level (,50 lb body weight and 90 lb/day at.8% fat). Values based on field calculations for hybrid moisture and DM yield; laboratory values for CP, NDF, NDFD, starch and ash concentration; and book values for NDFCP (.%) and ether extract (.%) concentration were used for spreadsheet calculations. For MILK006 predictions, we assumed that kernel processing occurred. How To Use Results NDF is a negative indicator of forage intake potential; higher NDF concentration generally implies lower animal performance potential. IVD provides an estimate of forage dry matter digestibility, and NDFD estimates digestibility of the fiber fraction. Starch concentration is positively associated with digestibility because starch is assumed to be 00% digestible. Relatively higher IVD, NDFD and/ or starch concentrations generally imply greater animal performance potential. Milk yield per acre represents the combined effects of yield and quality. Corn hybrids differed in yield, forage quality, and milk production potential at all sites. Means and least significant difference (LSD) values at the 0% probability level are shown for each parameter at each site. Where the difference between two hybrids for a particular trait and site is greater than the LSD value, there is a 90% probability that there is a real difference between the two hybrids for that parameter (i.e. moisture, yield, quality concentration or milk production).
