Summary
In a field of commercially grown potatoes the yields of a late variety, Green Mountain, and of an early variety, Cobbler, were found to be inversely related to the numbers of golden nematode cysts found in the soil. In addition, the tuber yields were inversely related to numbers of immature females present on the roots of both varieties. These relationships existed when either total yields or U. S. Number 1 size yields were used. Green Mountain yields were reduced to a greater extent than were the yields of the Cobbler variety in the presence of high cyst populations in the soil and high immature female counts on the roots
