The above picture is a bird's-eye view of the 
Johnston Pioneer plant . . . today. Modern 
equipment used throughout ... is replaced with 
new ... whenever a handling method can be 
improved. 
In this new laboratory building, Pioneer scientists 
test and check the results of field tests on the 
many hundreds of Pioneer inbreds and experi- 
mental hybrids. Warm and cold germination 
tests are made on the commercial hybrids now 
being sold.
