The dry weather in July caused the flax to begin to ripen early and the heavy rains in August started a second growth. This made the flax late in maturing and reduced the yields. In 1912, 17 varieties were grown. These were seeded on May 14 in twentieth-acre plats on land that had been cropped to winter wheat the year before. Flax was the only spring grain that pro- duced any seed in 1912, the others being destroyed by hail. The. Fig. 15.—Varietal test plats of flax at the Judith Basin substation, 1915. (From a photograph lent by the Office of Exhibits, U. S. Department of Agriculture.) hail came when the flax was m fuU bloom. While it undoubtedly reduced the yields, the plants made a second growth and produced a fairly good crop. In 1913 the flax was grown in tenth-acre plats on fallow ground. The yields that year were quite Satisfactory. In 1914 and 1915 the flax varieties were grown on fallow ground in rephcated fiftieth-acre plats. A view of the varietal test plats in 1915 is shown in figure 15. The yields in 1914 were reduced by a disease known as canker. This disease attacks the young plant just above the cotyledons and apparently stops its growth until it puts out basal branches below the injured part. The growth is then normal, but the time required to produce these branches makes the plants late in maturing. The seed is produced on these branches, which take the place of the central Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Un
