Proso Millet Management Guide


  • Planting Time: Late Spring – Mid Summer

-Millet needs a minimum soil temperature of 60 degrees to germinate

  • Drilled Seeding Rate: 20-25 lbs/acre
  • Ideal Seed Depth: 1/2” – ¾”

-Millet can also be broadcasted and rolled or packed to gain seed to soil contact


  • Use the fertilizer rates below for maximum yield potential:
  Recommended Application Rate (Lbs/acre)
Soil Fertility Level Nitrogen (N) Phosphorus (P2O5) Potassium (K2O)
High 15 0 0
Medium 25 25 20
Low 40 40 55

*Rates are recommended if no soil test is taken.

  • Apply ½ rate of nitrogen before or immediately after planting, and the other ½ rate 30 days after emergence
  • If crop is intended for multiple cuttings, split apply the total rates recommended between each cutting
  • Do not exceed a total of 10 lbs/a of N+K if fertilizer is placed in-furrow at planting

Weed Control

  • Plant into a clean, weed-free seed bed and use the herbicide options below for optimal weed control:
Timing Herbicide Rate Notes Weeds Controlled Control Method
Preplant or Preemergence Makaze (Glyphosate) 32 oz/a Apply any time before crop emergence Grasses & Broadleaves Contact
Post- emergence Comet (Fluroxypyr) 0.5-0.67 pts/a Apply between the 2-leaf stage and before early boot stage Broadleaves Contact
2,4-D Amine (2,4-D) 0.5-1 pt/a Apply from 5-leaf stage to early boot stage Broadleaves Contact


Harvest Management

  • Proso Millet should be cut for hay between late boot stage and early seedhead emergence.
  • Harvest can be delayed until millet is more mature, but palatability declines significantly with mature seedheads
  • Anti-Quality Factors: Millets are less likely to have high levels of nitrates than other warm season forages such as sorghum. Under drought conditions, nitrate levels may rise and caution should be used if haying or grazing. There are no prussic acid concerns with millets.
