Relatively late planting of potatoes, i.e., between June 12 and 25, has become the prevailing practice in the dryland areas of western Nebraska. Late planting distinctly improves the color and type of tubers, and reduces losses due to insects and diseases (especially soil-borne diseases caused by Fusarium and Streptomyces).

Beginning in 1937 and continuing to 1954 (in all except two years), potatoes growing with dryland culture at an altitude of 4,000 feet on the Box Butte Experiment Farm were harvested semimonthly to determine: time and rate of tuber growth; size of tubers produced by various dates; time and rate of development of scab and other defects impairing the grade quality of the tubers; and change in dry matter content (specific gravity) of tubers as the seasons progressed.
