Years
During the past 50 years, much progress has been
made in Kentucky to improve the efficiency of producing
corn. In 1912, the average yield was 27 bushels per acre.
This past year the state average was 55 bushels per acre,·
more than double that produced 50 years ago.
Little progress was made in improving production
efficiency until 1942. Since 1942, the progress made can
be divided into two periods. Yields ranged from 30 to 40
bushels from 1942 and 1955. The second period of in-
creased efficiency from 1955 to 1961, yields have ranged
from 40 to 55 bushels.
Although progress has been made, are Kentucky corn
growers keeping pace with other states? The answer is no
How can this lag in efficient corn p
