Posted January 26, 2004: Just as the organic movement
brought about a ground swell of change in agriculture, with its
impact sending out ripples in all directions, so too is the seed
savers' movement slowly spreading, preserving old varieties of seeds
and wresting back control from the large corporations who have dominated
the seed market. “We were missing one piece from the organic
farming movement,” said Fedco Seed founder CR Lawn at the
Restoring Our Seed Conference. “We almost forgot about the
seed. We are taking back our birthright,” he declared.
Over 100 people gathered for the two-day conference on seed saving
held in Brattleboro, Vt., on November 15-16. The heads of several
seed companies were in attendance, as were growers of seed at various
levels of scale--from under an acre to over 20 acres. Workshop topics
ranged from the biology of seed production and breeding for disease
resistance to seed cleaning techniques. Overall the mood was positive
and enthusiastic, with information freely shared among the participants.
The need to save seed on a local and regional level was made clear.
Organically produced seed is in short supply and urgently needed
by organic growers. Regionally adapted varieties are not being developed
by the large seed companies. They have no interest in developing
a tomato that will grow well in Vermont or Maine, but a small regional
seed company such as High Mowing Seeds does indeed. “The critical
linchpin of agriculture is the seed we use,” said seed breeder
Dr. John Navazio.
Don't be a seed-slave
There are a number of ideas to keep in mind if one is interested
in growing seed on a commercial basis. For one thing, you should
pick crops that you like. “It has to be fun. Otherwise you’ll
be seed-slaving,” declared Navazio. If you pick a crop to
grow that you don’t feel some sort of bond to, you won’t
enjoy it, so choose wisely.
Secondly, you need to understand the plant you have chosen and
determine if you should even try to grow it for seed in your area.
Just because it will grow there and even set fruit doesn’t
mean it should be grown in your region for seed, cautioned Navazio.
He cited the example of some tomato varieties, such as Legend and
Oregon Spring, which will set fruit in colder, wet areas, but not
produce seed. So be forewarned and do your research first. In fact,
warned Navazio, if a seed company asks you to grow a specific variety,
make sure it’s not the problem child nobody else wants to
grow. Some crops are dogs, he emphasized. So, be careful.
It is critical to learn the biology of seed reproduction. A grower
must be fully aware of issues such as selfers and crossers, isolation
distances, minimum numbers to grow to avoid inbreeding depression
and related subjects. This information is all available in books
on seed saving and applicable web sites.
Seed growers' training program
Tom Stearns of High Mowing Seeds has initiated a seed growers'
training program in Vermont. He distributes a manual full of detailed
descriptions of how to grow seed and five packets of seed to prospective
growers. He then provides technical assistance and on-farm visits,
where feasible, to the “growers in training”. He gives
the growers a target seed yield and stresses that they treat their
venture as a commercial crop even though it’s on a small scale
to start with. When the seed is ready, they send it back to Stearns,
who cleans it and tests the germination rate, providing feedback
on the product to the growers. This approach is used for growers
at all levels of experience. Even if you've grown and marketed vegetables
for 20 years, growing for seed is distinct area of expertise, with
its own learning curve.
One item of discussion was the levels of scale that are feasible
for seed production. Stearns noted that seed companies are interested
in varying amounts of seed, depending on the size of the seed company
and the seed variety. Navazio observed that a company such as Johnny’s
Seeds, for instance, might be able to find someone who can provide
3,000 lb. of a carrot seed, and another to provide 20 lb., but need
a grower at a level in between those amounts. So, niches for growers
at all levels exist.
Don't grow on spec
That said, grow only what you’ve got a contract for. Don’t
grow on spec, urged Fedco's Lawn. Fedco doesn’t want to buy
excess seed and sit on it for five years. It ties up money in inventory
and costs money to store it, he pointed out. Seed breeder Frank
Morton stressed that anyone can flood the market with any one variety
in a single year. It takes no skill to do that, he noted. It does
take skill to figure out how much you need to grow to fulfill your
contract and use the rest of your land to grow other seed that won’t
cross with it.
It will take some calculation to determine the economic viability
of growing a particular amount of a seed variety. For instance,
Stearns points out that growing 5 lb. of one high-priced variety
could pay the same amount as growing 50 lb. of a lower-priced variety.
But, you’d have to take into account many factors, including
your growing environment, seed yield for the varieties in question,
equipment needs, etc.
Most traditional seed companies are not used to buying dirty seed
that hasn’t been germination-tested from growers whose fields
they have not been inspecting. These services are provided for larger
growers. Perhaps, speculates Stearns, if there was a middleman to
do all of this--germ testing, seed cleaning, field inspections,
distribution, etc., maybe in the form of a co-op--it would help
smaller seed producers sell seed to larger companies.
From harvest to clean seed
Another issue is that of seed harvesting and cleaning. Stearns
suspects that it is the threshing equipment and not the seed cleaning
equipment that farmers need to buy and share. Threshing involves
basically smashing the plant material to separate the seed from
the plant. Seed cleaning involves separating the seed from the chaff.
The final stage of seed cleaning allows for seeds to be separated
from weed seeds, immature seed and other contaminants, bringing
the percent germination rate up.
High Mowing Seeds does have some ability to provide seed threshing
equipment, for both wet and dry seeds, to their growers. Your level
of scale has a lot to do with what your needs are equipment-wise.
A small-scale grower might be able to cut dry seeded crops, such
as beans, in the field, bring them into a dry space, and then mechanically
separate the seeds from the plant by thrashing them in some way.
People have bagged them and stomped on them, put them under a tarp
and run over them with a truck, and used other innovative methods.
Larger-scale growers need to resort to using combines for harvest.
Wet seeded fruits such as tomatoes, cukes, melons and squash present
other issues. Small quantities can be handled by hand, but larger
amounts require the use of machinery. Winter squash and pumpkins
quickly become unmanageable at even relatively low levels of scale,
and machinery to handle the job proves invaluable.
Stearns of High Mowing Seeds is also in the process of developing
both a seed-cleaning facility and a testing lab that can be utilized
by growers, enabling them to avoid investing in their own equipment.
Rowen White, assistant farm manager at Hampshire College in Amherst,
Mass., is developing a seed-cleaning center to be housed at the
Seed cleaning is a major issue for growers. “I love seed
cleaning,” states Stearns, but you won’t find many people
who do. It is the single most frustrating thing for new growers,
he believes. Basically, though, he thinks that if you have the right
tools and techniques, you too will grow to love it.
Matt Rulevich suggests thinking the entire seed-cleaning process
through before getting started, as you don’t want to spend
more time at it than you really need to. High Mowing Seeds has prepared
a number of seed-cleaning fact sheets which provides instructions,
lists of tools, estimated costs, and other valuable information.
Unless a grower is producing seed at a huge scale, relatively simple,
low-cost items such as buckets, fans, and screens can be used for
seed cleaning. Stearns described one set-up for cleaning dry seed
that involved two box fans set up one behind the other on a chair,
with several buckets in front of them on the ground. With two fans,
the speed can be adjusted as needed to provide variable levels of
air movement. Seed is poured from a square bucket in front of the
fans, with viable seed landing in a bucket and debris such as chaff
and immature seed being separated out due to differences in weight.
Be aware of the learning curve
In general, the speakers emphasized the learning curve that faces
those just beginning to grow seed. A much larger pool of information
now exists than was available even five years ago in terms of seed
growing on a smaller-scale basis. Still, although there are a number
of experienced, talented and dedicated seed breeders and growers
to provide this information, some of it will, by necessity, be gained
only by trial and error. For instance, learning to assess the point
at which crops should be harvested so that as much seed as possible
is mature, but the crop isn’t shattering in the field or rotting,
takes hands-on experience.
Finally, pointed out Frank Morton of Wild Garden Seeds, there were
no workshops held on how to make money selling seed. The money is
the hard part of the business, he emphasized. The seed business
is currently dominated by the giants, but he strongly believes that
when one of them fails, the small growers will be there to pick
up the pieces. We just have to avoid letting the domination by large
companies happen again, he said. We need lots of small growers.
