Weather Not A
Factor In Long
Run Corn Yields
Increases in corn yields in
the 'Corn Belt 'between 1929
and 1962 are attributable al
most entirely to the adoption
of hybrid seed, the use of
nitrogen fertilizer, and other
Improved production prac
tices, according to the U.S
Department of Agriculture
USDA says that while
weather affected yields for
short periods within the 30-
year span, its effect for the
entire period was negligible
During that time, bad weather
lowered yields by as much as
good weather raised yields.
Economists used a Weather
index to separate the effects
of weather and technology on
trends in corn yields. Adjust
ing yields with the Weather
index shows what the level of
yields would have been if
weather had been normal in
each year.
Corn yields moved up each
time Corn Belt farmeis be
gan using a new technique.
When the technique became
widespread, yields hit a
plateau until the next inno
vation started to make an 1111-
pac‘
The adoption of hybrid seed
pushed yields up steadily
from 1933 until 1948, when
99 percent of the corn planted
by Corn Belt faimeis was
hybrid. Yields remained on
a plateau until the middle
1950’s Increased use of nitio
gen fertilizer raised yields to
a new plateau by 1956 About
1961 farmeis began fertilizing
at higher rates and once again
yields increased
In all, Com Belt yields ad
justed for weather lose from
30 to 70 bushels from 1929
to 1962. Hybrid seed account
ed for 20 bushels of the in

caused another 15-bushel rise.
The remainder of the increase
resulted from higher planting
rates and other improved
practice:.
While raising the average
level of corn yields, technolo
gical advances have ironed out
some of the variations in
yields. In yeais of bad
weather yields do not decline
proportionately as much as
30 years ago, but in yeais of
good weather they do not in
crease as much either, the
scientists found
Even greater fertilizer use
and higher planting rates
are likely to be the major
source of futuie increases in
coin yields, it was concluded.
