In 1951 in studies in New Brunswick, increases in the height and width of potato plants were greatest during the fifth week after emergence. The average daily increase at this time was approximately 7/10 inches in height and 8/10 in width.
The thickness of the main stalk increased most rapidly from July 28 to August 3, or during the latter part of the fourth week after emergence. After this the rate of increase dropped rapidly, levelling off about August 13.
The products of increases in height and in width show that the rate of development of the potato was greatest during the fourth or fifth week after plant emergence.
The products of photographic measurements of height and width of plants show that, in 1950 and 1951, greatest growth occurred during the fifth and fourth weeks, respectively, after plant emergence.
