Excerpt from The Comparative Winter Hardiness of Oat Varieties Winter-killing is the major limiting factor in fall-sown oat pro duction in the United States. Low temperature is the principal cause of winter-killing, although heaving, smothering, high winds, and unfavorable soil-moisture conditions may be contributing factors. Reliable information as to the relative winter hardiness of different varieties seeded in the fall has been limited. The uniform winter hardiness nurseries, begun in 1926 by the United States Department of Agriculture in cooperation with the State agricultural experiment stations, have in recent years supplied this need to a considerable degree, and it seems desirable to make this information more generally available. This circular reports the results for the 10-year period from 1927 to 1936. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
