36 ROBSON QUALITY SEED, HALL, NEW YORK 
CERTIFIED HYBRID FIELD CORN 
1 Bu. will plant 4 acres for silage 
1 Bu. will plant 5 acres for grain 
It is estimated that 68% of the field corn grown in the United States in 1946 was hybrid varieties and that 
this 68% produced 80% of the corn crop. Hybrids are more resistant to dry weather, ripen more evenly, and 
produce more bushels per acre. Certified hybrid corn is so vigorous that care should be taken not to plant it 
too thick—36 inch rows and 9 inches in the row for silage and 12 inches when the corn is to be grown for grain. 
Growers tell us that Certified Cornell 35-5 will shell more pounds of corn than any other variety they have 
ever grown. It also makes good silage in areas where the season is short. Certified Cornell 29-3 is the most 
popular hybrid for silage in the Northeast but is more susceptible to smut and does not stand quite as well as 
Wisconsin 416 and Wisconsin 464. 
CERTIFIED CORNELL HYBRID 35-5: 95 days. A 
new early yellow dent hybrid field corn introduced 
by the N. Y. State College of Agriculture. Stalks 
7 to 8 ft. high, ears 8 to 9 inches, kernels narrow, 
deep, yellow. A very attractive corn that yields 
well and is well adapted to New York State condi- 
tions. The narrow kernel makes Cornell 35-5 a 
favorite with the poultrymen. 
CERTIFIED CORNELL HYBRID 29-3: 110 days. 
Originated at Cornell as a silage variety for use on 
the higher elevations of New York State and also 
found to be an excellent husking variety on our 
farms where the elevation is below 1,200 ft. Stalk 
9-10 ft., slender and leafy. Ears 9 to 10 inches long 
and slightly tapered. The dented kernels are yellow 
tinged with red. Cornell 29-3 has largely replaced 
West Branch Sweepstakes for silage—the silage con- 
tains 10% more dry matter and will feed your cows 
two weeks longer. 
WISCONSIN HYBRID 416: 105 days. Very similar 
to Wisconsin Hybrid 404 but about 5 days earlier. 
Stalks are medium tall; ears long and somewhat 
slender. Its field appearance is very good and it is 
noted for easy husking. 
WISCONSIN HYBRID 464: 110 days. A leafy yel- 
low variety of the same season as Cornell 29-3 but 
one that we find has a stronger stalk and root than 
29-3. It is also more resistant to smut. Suitable 
for silage on elevations in New York State over 1,200 
ft. and for both silage and husking at elevations from Seite probeom: Sery puceoeece eee pet: Halls ike a
