Effect of Soil Temperature at Different Growth Stages on Growth and Development of Potato Plants1
Abstract
The effect of soil temperature on potato growth depended on the stage of growth of the plant. The three growth stages studied were (a) planting to emergence, (b) emergence to 30 days, and (c) 30 days to maturity. In the first growth stages the plants did not emerge at 48F. However, if the potato plants were allowed to emerge, growth stage (b), and then placed at 48F, top growth developed. In the second growth stage (b) root growth was less sensitive to temperature differentials than top growth. In the third growth stage (c) soil temperature affected root concentration with depth but did not influence root distribution in a lateral direction. Tuber yield increased with increased temperature to 72F and then decreased at 84F. At 84F specific gravity of tuber was lower than at the other temperatures studied. Tuber shape was also affected by high soil temperature.

Average day/night temperatures recorded in the greenhouse during the experiment were higher than recommended values for potato during the first phases of plant development (optimum for sprouting 15 °C), while close to the reference thermal level during tuberization (optimum for tuber maturation 18 °C).
“The average day/night temperatures recorded in greenhouse during the experiment resulted higher than the recommended values for potato during the first phases of plant development (optimum for sprouting 15 °C), while they were closed to the reference thermal level during tuberization (optimum for tuber maturation 18 °C) (Epstein 1966).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
