Valley bottom lands of extreme southern Ohio: 
(a) Second bottom lands—U. S. 44. L3I. 
In each group of recommendations In the above table the hybrids are arranged in approximate order of 
maturity—the earliest first. However, the maturity differences are often very slight and may be insignificant 
under some conditions. For Instance, the differences in maturity between la. 939, and W17 are slight 
and often not evident. 
PENNSYLVANIA —For southwestern counties in val¬ 
leys and most productive uplands use W17 or Iowa 
939. For very productive bottoms use U. S. 65. In the 
absence of adequate yield trials we suggest for trial 
only and not for general planting until after trial, In 
southeastern Pennsylvania Including territory around 
York, Gettysburg, Lancaster, and up as far as Harris¬ 
burg, Hybrids U. 8. 52 and L 31. As you go north 
choose for trial Hybrids W17, Iowa 939 and U. S. 65. 
Use earlier Hybrids on higher elevations. 
WEST VIRGINIA—For the uplands in Ohio Valley 
territory use W17 and Iowa 939. For bottom lands 
along Ohio and nearby streams use U. 8. 52 or L31. 
KENTUCKY—On uplands, Indiana 614, U. S. 52 and 
L31 are adapted. We offer no Hybrids suited to the 
bottom lands of this state.
