Specific gravity — Dry matter relationship in potatoes
- 52 Downloads
The specific gravity-dry matter relationship of potatoes grown in North Carolina was determined.
Location of production and variety of potato had a statistically significant effect on the specific gravity-dry matter relationship. Size of tuber was not significant but appeared to be somewhat greater than the effect of variety. These factors, though in some cases statistically significant, did not greatly affect predicted dry matter values.
A prediction equation and a prediction error were given for the estimation of dry matter content of potatoes from specific gravity measurements irrespective of size of tuber, variety or location grown in North Carolina.
