1t will be noted that the demand
for nitrogen and phosphorus is much
less for sweet corn than for field
corn. In the case of potash the con
ditions are the reverse apparently
due to the fact that this element is.
directly associated with the develop
ment of sugar.
Sweet corn also provides an early
soiling crop. 1t may be harvested in
early September before the field corn
is sufficiently matured and at time
when greed feed is usually scarce.
Sweet corn silage has a very high
value. The stalks are sweet, palat-
able and contain less crude fiber and
hence a higher percentage OF diges-
tibe matter than field corn.
StowelIs Evergreen and Country
Gentleman are are two varities most
grown in IOwa-the former predomi-
mating. The seed is usually furnish
ed by the canning company in order to
insure the uniform planting of the
same variety. Good corn land does
equally well for sweet corn. The re-
turns are not satisfactory on thin
impoverished land.
Method of Seeding and Cultivation
Fall plowing to a depth of about six
inches has many advantages. The inn
portance of a fine mellow seed bed
cannot be over emphasized. Thor
oughness at this point has much to
do with securing a good stand and a
heavy yield.
Sweet corn is not as vigorous a
plant as field corn and is usually
planted directly following field corn.

with the factory operator in order
that an even flow Of the crop may be
provided for the factory in the fall.
The seed is planted one and one
/ half inches deep or down to moisture
/ in a dry soil and four to five kernels
/ to the hill. This will require about
nine pounds of seed per acre. The
/ harrow should follow the planter to
wipe out the wheel tracks. On slop-
| ing land it is well to stop in time to
/ do this each day. Even a light shower
| the following night may start a gull
ley down the wheel track as well as
uncover the seed.
From two or three civilizations with
a six shovel cultiyator and an equal
number with a surface cultivator the
latter part Of the season are common
ly given. Deep cultivation late in the
season breaks off the roots and is
likely to do more harm than good.
A maintenance of a dust mulch tC
maintain the soil moisture is a Vita
practice. A ton of roasting ear:
contains approximately 1900 lbs o.
water. Both the yield and quality o.
the crop are effected by the mOisturS
supply.
The harvest season under Iowa con
ditions usually extends from the mid
: die of August to the second or thir(
week in September. The ears ar,
