Specifications

Vegetable growing has become a highly specialized and intensive activity. As a result of the ever increasing demand for better quality vegetable growers and plant raisers require an improved quality of the basic material. The demand for specific seed forms and more information about seed quality has strongly increased to better influence emergence and required number of plants. Seed is a natural product. The often varying environmental conditions thus influence final results. It is therefore often not possible to give detailed information about emergence and other physical seed characteristics. To meet the wishes of clients as much as possible RIJK ZWAAN has made up quality standards for the various seed categories. The germination percentages mentioned are RIJK ZWAAN minimum required figures and made up according to ISTA methods and tolerances. In cases where the seed does not apply with these product specifications RIJK ZWAAN will inform the client.

General definitions

 

Normal Seed
In general, normal seed has not been subjected to special processes. It is sold by weight
and/or by count, depending on the product. Normal seed complies with national standards.

Precision Seed
Precision seed has been subjected to additional processes. It has a uniform size and high
germination. Precision seed is sold by count.

Priming
Priming is defined as an activation of the germination process with the purpose to obtain
faster or more uniform emergence after sowing. Primed seed is sold by count.

Pelleting
Pelleting is defined as the process of changing the seed form by covering it with a material,
the main purpose being to improve uniformity of size and shape resulting in improved
sowing ability. Also additional ingredients may be added. Pelleted seed is sold by count.

Filmcoating
Filmcoating is a full covering, usually pigmented layer, around the seed. The original seed
form remains intact. Additional ingredients may be added. Filmcoating treatments that
contain insecticides are normally identifiable by color coding. Filmcoated seed is sold by
count.

Gluecoating
Gluecoating is a process which fixes the applied crop protection products in an almost
dustfree manner to the seed. A pigment may be added.

Germination
Germination figures relate to ISTA procedures and are valid at the time of despatch.
