Seed weights & sowing rates
Sowing rates for individual situations vary. The
following are general guidelines.
Open Information Sheet
Seed analysis certificate
All seed has its own line number, printed on the
side of the seed sack, and each line of seed has
its own seed analysis certificate. The seed analysis
certificate describes the quality of a line of seed,
laboratory tested in a standard way.
Open Information Sheet
Endophyte seed tests
ALL Barenbrug ryegrasses containing endophyte
are tested prior to sale and have a current test at
time of sale. The type of endophyte contained in
the seed is stated (e.g. NEA2).

Storing seed with endophyte
Endophyte levels in ryegrass seed drop off over
time. On-farm, store seed with novel endophytes
in a cool, dry place. Sow seed within one month of
purchase.

Seed certification
Seed certification is an industry programme to
ensure cultivar identity. It is run by AsureQuality
for the New Zealand Seeds Authority (NZSA).
Open Information Sheet
Tetraploid seeds
Some ryegrass, red clover and brassica cultivars are tetraploids. They have larger seeds than diploids, so are sown at higher rates. In perennial and hybrid ryegrass, tetraploids need different management for best performance
