Records shown below under each of the 3 
maturity belts are based on averages of 
several years of testing in Pioneer hand 
planted, replicated test fields. Twenty hills 
of each entry are planted in six different lo- 
cations in each field and averaged at har- 
vest time. A number of fields are planted 
annually in each maturity belt and results 
averaged. Then results of preceding years 
are averaged with latest figures.
