SEED LIST 
FALL, 1937 
Oklahoma Crop Improvement Association 
Stillwater, Oklahoma 
The Oklahoma Crop Improvement Association 
is an organization of Oklahoma farmers and seeds¬ 
men cooperating closely with crop specialists of the 
Oklahoma Agricultural and Mechanical College in 
producing and marketing pure bred seed of the 
adapted and tested varieties of field crops. As a 
result of this cooperation the Oklahoma Seed Cer¬ 
tification Standards have been evolved, and ap¬ 
proved officially by the department of agronomy of 
the college. Members of the association are expect¬ 
ed to meet these standards in the sale of any seed for 
planting purposes. A careful system of seed inspec¬ 
tion is maintained and the methods used by mem¬ 
bers are subject to examination at all times by in¬ 
spectors of the association. 
Two classes of OKLAHOMA CERTIFIED SEEDS 
are on the market; namely, “Registered seed” and 
“Certified seed.” Registered seed is handled by 
such mthods as to insure highest purity and quali¬ 
ty and is designed for use as foundation stock seed. 
Such seed is the progeny of carefully controlled 
seed plots. Registered seed is recleaned and grad¬ 
ed, and sold in approved bags which have the asso¬ 
ciation tag for registered seed, BLUE IN COLOR, at¬ 
tached. The amount of registered seed available on 
the market is limited. Prices are of necessity high¬ 
er than prices on certified seed, and are fixed joint¬ 
ly by the association directors and the growers. Re¬ 
gistered seed must be sold in approved bags and its 
sale is restricted to the grower himself, unless the 
bags are sealed. 
Certified seed is produced from registered seed, 
or from a preceding crop of certified seed on the 
grower’s own farm. Certified seed is the most im¬ 
portant class of association seed sold commercial¬ 
ly. Certified seed is sold in containers with the as¬ 
sociation tag, YELLOW IN COLOR, attached. 
In some instances dealers prefer to buy certi¬ 
fied seed, bin run, unbagged, in truck or carlots, at 
specified premium above the market. Dealers inter¬ 
ested in such purchases are invited to write direct¬ 
ly to the growers listed for samples and special quo¬ 
tations. However, certified seed purchased in this 
way shall not be resold by the dealer as OKLAHO¬ 
MA CERTIFIED SEED, bearing the association tag 
for certified seed, and the grower is not considered 
further liable by the association for the purity and 
quality of the seed. 
IMPORTANT; Persons interested in buy¬ 
ing OKLAHOMA CERTIFIED SEEDS are urg¬ 
ed to write or send a postal card request to 
several growers of each variety. Indicate the 
amount of seed you want to buy and ask for 
quotations and samples. If you have any dif¬ 
ficulty in locating the seed you want, you 
are urgently requested to write the Oklahoma 
Crop Improvement Association, Stillwater, 
Oklahoma, concerning your needs. 
The purpose of this seed list is to /enable pros¬ 
pective buyers to select seed of high quality and 
the variety desired. The seed crops of all members 
must pas9 one or more inspections in the field, and 
after harvesting, a sample of seed representative of 
that which the grower expects to sell is sent to as¬ 
sociation headquarters for inspection. The associa¬ 
tion, however, makes no guarantee of any lot of 
seed on the list, and assumes no responsibility in 
connection therewith, for upon the grower rests the 
responsibility of delivering stock equal in quality to 
the tested sample.
