Here a picture of planting browntop millet. Browntop millet (or dixie signalgrass) is grown for several different things, here for wildlife attraction (dove fields) with many plantations in Thomas County. It is also used in erosion control, straw production, and forage production. It is occasionally used for grazing or hay production. Browntop typically grows only to two to five feet tall and produces only 60 to 70 percent of the dry matter of pearl millet or sorghum x sudan hybrids.
Browntop millet can be planted from mid-April until mid-August in most locations, though later plantings will result in lower yields. To establish browntop millet, broadcast 20 to 25 lbs of seed per acre on a prepared seedbed in spring. Seed should be covered to a depth of 1/2-inch in a firm seed bed.
