pre-sprouting

Benefits

  • Adds value to high-quality large seed potatoes
  • Cutting makes a number of varieties easier to plant, such as Agria, Nicola and other elongated varieties
  • Cutting eliminates apical dominance. Cutting activates the dormant eyes on the tuber. This results in 10-15% more stems per m² distributed more uniformly
  • The new harvest is more uniform in size
  • In some varieties, the old mother tubers are exhausted sooner and better.
  • Cutting encourages the plants to emerge a week earlier. 10-14 days of pre-sprouting means harvesting can take place 2-3 weeks earlier
  • In financial terms, the knife cuts both ways:
    1. Cheaper seed potatoes (± €100 to €500 per ha.)
    2. Better grades give higher yields
  • Cutting promotes rapid wound healing and sprouts in the pre-sprouting bags. See the advice below.

Advice on cutting and pre-sprouting*

  • Use healthy and sound seed potatoes.
  • Temperature of tubers before cutting 12°-14°C.
  • Bag potatoes after cutting in one pass.
  • Put the germination racks in your shed for two weeks for proper wound healing.
    This will keep the cut poters from drying out and rotting.

Indoor
wound healing
  • Increase the temperature to 15 to 20°C
  • Ensure the relative humidity is as high as possible during the first 24 hours
  • Place the cut seed potatoes in pre-sprouting bags in the shed for two weeks. This prevents the development of rot and the cut seed potatoes will not dry out
Hardening off
outdoors

When the cut surface has cured, after two weeks, the pre-sprouting racks can be placed outdoors to harden off further.

Tip: cut through a few seed potatoes first to check whether the surface has cured.
