Hybrid Fall Rye Agronomy

Seed rate:

  • 0.8 unit per acre
  • Seeding rate of each lot will vary depending on seed size and germination = 65-85 ibs per acre (18.3 plants for square foot)
  • one unit = 1 million viable seeds 

 

Seed depth:

  • 3/4 inches is ideal
  • Seeding depth is critical to reducing ergot risk

 

In crop:

  • Rye should be sprayed early, late April to early May is ideal (spraying late increases risk to the plant)
  • Rye will suppress wild oats, late-season wild oats can still be a concern
  • Broadleaves: Do not use MCPA as it can increase ergot risk. Also, try to avoid 2-4D
  • Grassy Weeds – Liquid Archive and some use no wild oat herbicide
  • Tram lines are beneficial so the flowering timing is even for reduced ergot risk

 

Fungicide:

  • Fungicide is rarely needed. If you are doing one, do not do it during flowering as there are worries about pollination. (Stem rust is not a big concern but could be as most energy in rye comes from the stem)
  • Rye will head out very early (late May).
  • Rye harvest timing will be earlier to similar to winter wheat
  • Rye has almost double winter hardiness of winter wheat
  • 14% is dry but if straight cutting it can be more prone to shatter if left to dry in the field. It can be put on air from under 18%
  • Bushel weight of rye is 56 lbs/bu
  • Makes a good silage option with very high tonnage & nutrition similar to barley
  • Hybrid rye has very good drought tolerance and yield elasticity
