The 1939 Iowa Corn Yield Test


Book Description

"The Concord grape and grapes of this type and hardiness which are the grapes most widely grown in Iowa, require yearly pruning if the grower wishes to obtain heavy annual yields of large-sized, high quality fruit. The illustration on the cover of this bulletin indicates the development and distribution of the fruit which may be expected on correctly pruned vines." -- p. [227]
