            When it comes to your basic cool-season legume for deer forage, alfalfa (Medicago sativa) can’t be beat.  It is a perennial, but it can also be used as an annual in deer food plots, especially in more southern regions. 

            Alfalfa does not do well on clay soils; keep that in mind if your plot is located in such an area.  At about 19% protein and 1.35% calcium, alfalfa is especially good to supplement whitetailed diets in the spring and early summer.

            Alfalfa is a common forage crop used to make hay for cattle and sheep.  If there are alfalfa fields located at or near your hunting ground, be sure to factor that into your food plot design.  Deer that are used to grazing alfalfa elsewhere may not be as tempted to try it in a new planting.

            There are other legumes that are often recommended for deer food plots.  A number of these are warm-season annuals: hairy indigo, partridge pea, cowpea and deer vetch (also known as Aeschonomyne).  Of these warm-season annuals, cowpea can have good early-season forage potential for deer in some regions.  A cool-season annual, Austrian winter pea, has also performed well in more southern regions.

            For a fall forage legume in my part of the world, though, you almost have to go with a cool-season annual like vetch (Vicia) or birdsfoot trefoil.  These can be important legume forage sources that can complement the grasses and grains in your food plot’s design.  Don’t forget to properly inoculate the seed before planting.

            And never plant a legume without taking a look at soybeans, which I’ll deal with in the next blog.
