What reading level is A Study By the Crop Survey Method of Factors Influencing the Yield of Potatoes book?
To quickly assess the difficulty of the text, read a short excerpt:
Stone (1905), at the Cornell station, compared various frequencies of hilled and level culture for five years on medium light soil. In each of these years, the yields were best under level culture, the differences ranging from 1 to 37 bushels per acre, the average favoring level culture by 14 bushels. Stone did not explain why the smallest differences in yield occurred in the two driest years, when the greatest advantage from level culture might have been expected. During three of these five ye...ars, he compared continuous level culture up to nine cultivations, with laying by and ridging the crop after from three to five cultivations. In these tests, the continuous level culture gave an average advantage of 54 bushels per acre. Shepperd and Churchill (1911), altho reporting no data, stated that level culture has given far better A STUDY OF FACTORS INFLUENCING THE YIELD OF POTATOES 1245 results than ridging in North Dakota, even in sections having the heaviest rainfall.
Since the system of cultivation as well as the depth of planting may have a part in determining the ultimate depth of the seed piece, this factor of depth of seed piece should be controlled in all tests of the influence of system of cultivation on yield.
