State Seed Laboratory


PLEASE NOTE: The State Seed Laboratory has moved to a new location:

The State Seed Laboratory determines the quality of seed used for planting. Seed testing yields information about seed lots for two purposes:

  • To determine if seed being offered for sale meets the guarantee stated on the label.
  • To provide information to the seed industry for labeling purposes.

In addition:

  • The seed lab supervisor is certified seed analyst (CSA) in germination and purity testing.
  • The seed lab uses the Association of Official Seed Analysts (AOSA) “Rules for Testing Seeds”.
  • Testing rules for OECD, ISTA and Canada can be done upon request.

The lab analyzes samples submitted by the public and other state and federal agencies. It also includes samples from the seed industry as well as official seed samples collected by NMDA inspectors.

Submitting a Sample

When you submit seed for analysis you must include this Seed Sample Submission Form with your sample. Samples without the form will not be analyzed.

You will be billed for the lab’s services. Charges are as follows:

Grass Seed $20 $12 $12 $6
All Other Seed $10 $6 $6 $6
TZ Test for Viability $20
Carry-over Vegetable Samples
(lots of 10 or more)
(dirty seed, other problematic analyses)

When submitting a sample to the state seed lab please review the directions and weights listed for testing.

To secure a representative sample, the following procedures shall be followed:

  1. Obtain access to all seed being sample by taking equal portions from evenly distributed parts.
  2. Use a probe or trier which will reach all areas of seed being sampled. For hard-to-sample and non-free-flowing seed and screenings, use the hand to withdraw representative samples.
  3. Individual-bag samples may be taken to determine seed lot uniformity.
  4. When the seed lot is in bags, sample ten percent (10%) of the bags but never less than five (5) bags.
  5. For bulk seed, take samples from evenly distributed parts. Take as many cores or handfuls as if the same quantity of seed were in bags.
