Remember the Big Three When Buying Seed Corn


Remember the Big Three When Buying Seed Corn

DuPont PioneerNow that harvest season is nearly complete, mailboxes will be filled with seed catalogs and silage plot research to help you make choices on what you plant next spring. DuPont Pioneer experts remind silage producers of the top three traits to focus on when buying seed for the 2014 season:

  • Yield/tonnage
  • Starch content
  • Fiber digestibility

Yield/tonnage is primarily a function of plant density, plant height and starch content. The goal for producers is to increase these traits during the next growing season.

Starch provides the majority of the energy concentration in silage and must factor heavily in hybrid decisions.

Meanwhile, fiber digestibility, as measured by neutral detergent fiber digestibility (NDFD), tends to be the trait of most interest. While small NDFD differences exist among conventional silage hybrids, the biggest driver of final NDFD is the plant’s growing environment during vegetative growth, so when evaluating NDFD, be sure to note the incubation time (24, 30 or 48 hours) and compare it with absolute values across different plot reports.

Some growers also like to evaluate index values such as milk per ton, milk per acre values and energy estimates such as Net Energy of Lactation (Ne-L). While index values can be useful in ranking hybrids, it still makes sense to look individually at the big three traits that most influence these index values.

Sharing the relative importance of the big three for your operation with your seed representatives can help them better sort through their lineups to suggest a suitable hybrid rather than selecting a hybrid based on an index value.
