I. No. 3697, grown from 1916 to 1919, inclusive. Winter wheat, although giving higher average yields, is somewhat less certain than spring w^heat in the vicinity of Newell, owing to poor germination of seed during cold fall weather, greater injury. Fig. 8.—Plats on dry land at the Belle Fourche Experiment Farm in 1917 : 1, Kubanka spring wheat; 2, Swedish winter rye ; .5, Kharkof winter wheat. Note the differences in stand and growth between the winter rye and the winter wheat due to the greater hardi- ness of the rye. from soil blowing, and the possibility of winterkilling. In case of failure of winter wheat from these causes, however, there is still an opportunity to sow spring wheat or some other spring crop. EXPERIMENTS WITH OATS. Oats is perhaps the most successful feed crop of all the small grains in this region. The yields of oats on the Belle Fourche Ex- periment Farm, however, usually have been less in pounds per acre than the yields of wheat. Oats are most profitably grown when sown on corn ground early in the spring. If drought or hot winds prevent the oats from filling, the crop can be cut for Please note that these images are extracted from scanned page im
