Recommendations

Use the information on the seed label and in the Seed Analysis Report to determine the quality of the seed you are purchasing. This will ensure that genetic identity and mechanical purity needed to help ensure a successful, weed-free, uniform seeding.

Purity and germination percentages found on the seed tag determine Pure Live Seed from which the bulk-seeding rate is calculated. The seed tag and Seed Analysis Report also will list the weeds including common, restricted noxious, and prohibited noxious found in the seed lot. Remember that weeds listed as common, restricted, and prohibited vary by state and no seed can be sold if it contains prohibited noxious weeds. Seed that is moved across state lines must meet the requirements of the state that is most restrictive. By monitoring the weed species in the lot, you can influence l what weeds are seeded in a planting.

The cheapest seed is not always the most economical. By comparing the purity and germination percentage between seed lots or mixes, you can see clearly which lots or mixes will produce the most potential seedlings after planting. All seeding recommendations are given in Pure Live Seed rates.

Refer to Montana Plant Materials Technical Note Number MT-46 for PLS seeding rates. These rates must be converted into bulk seeding rates before seeding. The drill must also be calibrated based on bulk seeding rates, not Pure Live Seed rates. Always place your order to the seed dealer as PLS seeding rate and check to make sure the dealer has mixed the seed as you specified.
