How to Grow
Time of Planting:
Allow soils to thoroughly warm up to 55-60 degrees F prior to
planting. Edamame seed do not germinate in cool soils so wait to
plant for best success.
DO NOT PRESOAK
||3" apart within rows. A 100-seed packet plants about 25 feet of row whereas one pound of seed plants about 300 feet of row. If planting an acre of edamame, plant 60 lbs of our varieties. Desired plant population per acre is 80,000 plants for good plant structure. Reducing plant population will lead to more plant branching. If your weed management is good, a lower plant population below the recommended is perfectly fine. However, increasing plant population too much leads to no branching, taller plants, delayed flowering and reduced pod set. BEWARE!
Edamame seed do not grow well when drilled in ultra narrow rows
of N. Soybeans are legumes and make the rest of the nitrogen they
Apply P and K according to soil test results.
The chemicals approved for weed and pest control for edamame soybeans are very limited because virtually no residue testing has been conducted on edamame. We recommend cultural and mechanical practices or organic production of edamame to control weeds and pests. Consult your local agricultural agent for latest changes to approved chemicals to use when growing edamame soybeans.
INOCULATE IF NEW TO SOY. If planting edamame soybeans in land not previously planted to soybeans, inoculate your soybeans to ensure that they can produce their own nitrogen. We sell small packets of soybean inoculant for you to coat the seed prior to planting.
|Edamame Seed are
Seed are alive. Remember to handle
edamame seed with care. Store in a cool dry place until planting and
avoid seed cracking by using the correct size seed plate (corn
plates work well).
Yield varies with your planting conditions and weather during the season. However, an average yield is .25 lb of pods per plant. If you are growing larger quantities, customers average 2.5 - 3.0 tons of edamame pods per acre. The yield of shelled edamame is about half the volume of edamame in the pod.
Extend your edamame
harvest by planting varieties of different maturities or by planting the
same variety in weekly successions for 4-6 weeks. Consult our
MAP to see what varieties are
appropriate for your area.
When to Harvest
Harvest edamame when
the beans in the pod are 80-90% expanded
or when the leaves
have changed from bright green to a slight yellowish-green color.
Handpick pods with at least
two beans per pod and select pods which are only bright green in color.
Avoid picking any yellowish or blemished pods. Wash pods to remove any
soil. Pods can be refrigerated for up to a week or blanch them for
2-3 minutes in boiling water and freeze them loose in zip-locked bags for later
eating throughout the winter.
When selling at a
farmerís market, small grocery, or if you have a CSA, cook some edamame
for your customers to taste. Boil or steam them in hot water until pods
are easy to pop open (about 4-5 minutes), then sprinkle the pods
generously with salt,
seasoned salt, or blackening spices
so that when you pop the beans out into your mouth, youíll taste the
salt or spices too. Remember: eat the beans, not the pods!
Sell edamame either
(1) loose by the pound in the pod, (2) shelled out of the pod to use in
stir fries or pasta dishes, or (3) try this traditional Japanese
method. Cut several plants off at the soil surface, remove the
leaves, but leave the pods on the plant. Bundle 3-4 plants together for
an edible bouquet! What a wonderful, healthy, and unique
