La Certa Chicory

Winter and summer active

La Certa Chicory is a variety selected in Uruguay for its tall, erect growth habit, leaf type, lateness in stem elongation and uniformity. It is more winter-active and earlier flowering than Puna and contains low levels of lactucin, the chemical that can cause a bitter taint in milk that make other varieties of chicory unpalatable at certain times of the year.

La Certa is known for:

  • fast establishment
  • high winter DM yields
  • high leaf to stem ratio
  • high annual DM yields
  • lower tainting of milk
  • ability to reseed when stand density decreases
  • high DM utilisation by stock due to its upright growth habit
  • decreased time in reproductive phase vs vegetative phase

In NSW DPI trials averaged across 3 environments, total herbage yield of La Certa over 22 months was 50% higher than Puna.

The benefits of chicory in mixes

Redgut is a livestock disease caused by excess protein in the diet. It is seen in pure stands of lucerne. The potential for this to occur can be reduced by including chicory in the mix. Chicory also increases the utilisation of the protein in the lucerne. Chicory suits similar soils to where lucerne grows and similar chemicals can be used to control broad leaf weeds in a mix between two. Include chicory at 1-2kg + Magna 804 lucerne at your local mix rate.

Pure stands of forage brassicas have been attacked by Diamond back moth Plutella xylostella as they move on from canola crops in dry years. If spraying for this pest is not desired you can mix chicory with forage rage at 1-2kg plus your local rate for Hobson forage rape. Chicory is resistant to diamondback moth and is also perennial so in the next year you can sow your grasses directly over the top of it in autumn.


During winter months La Certa produced almost twice as much above ground biomass as Puna reflecting its superior winter activity.

Chicory works in similar soils to those that lucerne grows in and they both go well in a mix together.

Chicory can be sown into a cultivated seedbed, or direct drilled, once weeds have been controlled.

Legumes are desired in a mix with chicory as it is a herb and requires a source of nitrogen for good growth.

Use 3-5 kg seed/ha when sowing as a special-purpose forage. When combined with clover, lucerne or forage rape sow chicory at the rate of 1–2 kg/ha.

Use 1–2 kg/ha in perennial pasture mixes.

Chicory mixed with Lucerne can prevent redgut which can cause death in sheep.
