Sunflower Population Rate Chart Based On Seeds Per Kilogram

NOTE: Meters deliver volume of seed, not specific population. Delivery rates vary up to 10 percent from rate chart values due to; seed characteristics, drive wheel circumference, operator judgment, and machine settings. Always perform calibration and verification checks to determine exact application.

NOTE: (See ADJUST RATE BASED ON SEED GERMINATION in this section for additional information.)
