320 
~NEW MIDSEASON HYBRI 
Robson 320 in just three short years has become the most popular field corn hybrid in 
much of New York’s corn growing areas. Dairymen report that when they feed Robson 320 
silage their milk production goes up. 
Growers of corn for grain find that Robson 320 stands late in the season when other 
hybrids go down. Yields of dry shelled corn are excellent too. Yields of 130 to 135 bushels 
of shelled corn per acre have been reported to us by enthusiastic growers of Robson 320. 
Our extensive field corn breeding program is conducted in New York State. By continually 
selecting our breeding material under the same conditions as found on most New York farms 
we have been able to develop superior hybrids well adapted to the Northeast. 
OUTSTANDING FOR STANDABILITY 
Robson 320 has a very strong root system that keeps it standing. It also is highly resistant 
to stalk and root rot diseases that cause so many corn varieties to go down before harvest time. 
Poor standability in many varieties of corn being grown for husking is the number one concern 
of farmers in the Northeast today. Robson 320 will stand up. 
ROBSON 320 STAYS GREEN 
The broad, heavy leaves stay green clear to the bottom of the plant. The stalk, leaves and 
husk are green and succulent after the ear is in the hard dough stage. This means a higher grain 
ratio in your silage, plus a more nutritious and palatable feed for the cows. Robson 320 will 
give you a longer period of time for silo filling and still give the maximum yields with highest 
feeding value. Many farmers report yields of 20 tons or more to the acre of the best, quality 
silage they ever grew. 
FOR SILO OR HUSKING 
Robson 320 is well adapted to much of New York State as a grain and silage corn. The ears 
are 8 to 9 inches long with 16 rows of deep, yellow kernels with a small cob. Husks ripen and 
loosen early permitting quicker drying and easier husking. Farmers rate Robson 320 as the 
ideal dual purpose corn for most sections of the Northeast. 
FULLY MATURES IN THE NORTHEAST 
Robson 320 matures between Cornell 35-5 and Cornell 29-3. It will fully mature for silage 
or grain in any area where 29-3 has been successfully grown. For comparison with other 
hybrids consult the 1952 Cornell Hybrid Maturity Guide. 
RESISTANT TO SMUT AND APHIDS 
Corn smut not only cuts the yield but lowers the quality of the silage. Robson 320 is very 
resistant to smut. Corn aphids decrease plant vigor and cause shrunken kernels. Robson 320 
is resistant to aphids. Growers have never reported aphids or corn smut on Robson 320. 
QUALITY IN THE SHOCK 
Growers who shock their corn and feed the stalks find that Robson 320 retains its green 
stalk and leaves after the ear is mature, thus greatly increasing the feeding value of their winter 
roughage. 
ROBSON 320— THE IDEAL HYBRID 
The succulent, green plant with mature ear makes Robson 320 an ideal ensilage hybrid. Its 
excellent standability, freedom from disease and big yield of high quality grain makes it a 
favorite grain corn. PLANT ROBSON 320 IN 1953.

*We recommend Drill Size for those growers planting corn with a grain drill. This grade 
can also be planted satisfactorily with any conventional planter if the recommended plates are 
used. Drill Size seed will not plant through planter plates used for flat kernels. 
Kernels well dented in the hard dough stage, a 
juicy stalk with green leaves clear to the ground 
make Robson 320 an ideal silage corn. Albert 
Hubbard of Avoca says, ‘‘You just can’t keep the 
cows away from Robson 320 silage.” 
Henry Flynn, Guernsey Breeder and President of 
the Yates County Dairymen’s League writes, 
“Best corn I ever raised —7 acres of Robson 320 
filled my silo. It has always taken 10 acres when 
I used other varieties.” 
Robson 320 Hybrid Field Corn has a small cob, a 
deep kernel and shells more pounds of grain per 
bushel of ears than other hybrids.
