Rb56-181 Rate Of Potato Tuber Growth On Dryland At The Box Butte Experiment Farm, H.O. Werner

University of Nebraska-Lincoln Extension: Historical Materials

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 …

Rb56-176 Influence Of Atmospheric And Soil Moisture Conditions In Diurnal Variations In Relative Turgidity Of Potato Leaves, H.O. Warner

University of Nebraska-Lincoln Extension: Historical Materials

Great variations in morphological characteristics and in ability to survive heat and drought are observable among the hundreds of varieties and thousands of clones used in modern potato breeding programs.

The experimental work reported herein was planned to determine:

1. The extent and nature of the changes in the relative turgidity (R.T.) of leaves of the potato plant during the diurnal cycle.
2. The extent to which R.T. of potato leaves is influenced by atmospheric conditions, soil moisture, variety and age of plants.
3. The extent to which visible evidence of water shortage in leaves is indicative of water loss from them as …
