For the three years, 1909, 1910, and 1913, the highest yield was from the August 16 seeding, with that of October 16 second. The great variations in seasonal conditions make it difficult to decide the best date for seeding wheat in western South Dakota. If rains occur early and are fairly abundant, early seeding is probably best. It is not always possible to conserve sufficient moisture to insure germination; hence, it is not usually safe to sow in dry soil with the expectation of receiving sufficient rain for germination. The safest rule seems to be to have the ground ready for early seeding, so that the seed may be sown early or late as the conditions seem to indicate. The results obtained on the Belle Fourche Experiment Farm appear to show that sowing as late as November 1 will often give better yields than are obtained from spring wheat. Because the.

NURSERY EXPERIMENTS WITH WINTER WHEAT. About 600 selected heads of Turkey, Kharkof, and Crimean wheats were sown in head rows in the fall of 1908. Practically all of these were sown in 60-foot rows the following year. As it seemed desir- able to test the best of these selections in field plats as soon as pos- sible, about 35 of them were sown in fiftieth-acre plats in the fall of 1910. Because of the extreme drought the next spring and summer no grain was produced. Enough seed was left from the 1909 crop, however, to sow in duplicate 60-foot rows in the fall of 1911. The seed did not germinate until the following spring, and the stand was then so thin that very low yields were obtained. Th
