Fast, safe and uniform field emergence provides the best start for the beet plants - and paves the way for a high and stable sugar yield.

MARIBO SeedPlus - an improved quality concept SeedPlus is a quality concept embracing new pro-

The concept is a combination of four new meth-

duction methods that optimise seed quality du-

ods that are applied to every seed lot:

ring multiplication, selection and treatment.

路 Maturity optimisation 路 Single seed selection 路 Individual activation 路 The multi-layer pellet principle


The less deviation in maturity, the more uniform the germination

Maturity Optimisation Seed that has reached full maturity will normally germinate faster and be more vigorous than seed that is not quite mature at the time of harvest. A sophisticated new technique helps us to determine the

In the field, the rejected seed performs very bad compared to the accepted seed. Not only is the number of emerged seeds very small, the plants are also less well developed.
