Abstract
Excerpts from the report: Potato-chip manufacturers often experience difficulty in obtaining stocks of potatoes that will process into desirable light-colored chips. Since this difficulty is sometimes encountered after unusually cold weather in the fall, it was suggested that relative maturity, or physiological age, of the potato and soil temperatures during the latter part of the harvesting season might affect the chipping quality. Experimental work was initiated to determine the effect of maturity on the chipping quality of Irish Cobbler potatoes as affected by (1) early, midseason, and late planting; (2) killing the vines by rotobeating 21, 10, and 1 day before harvesting; and (3) early, midseason, and late harvesting. The work was expanded in the second year to include the Kennebec variety.
