Winter wheat has produced higher average yields than spring 
wheat, but is rather uncertain on account of winterkilling and soil 
blowing. 
Spring emmer has not yielded as well as the best varieties of oats 
and barley. It is not resistant to extreme drought. Winter rye has 
yielded less than winter wheat, but it is hardier and more certain. 
Winter emmer and winter spelt are not hardy enough to be grown 
successfully in western South Dakota. 
The early varieties of oats, Kherson and Sixty-Day. have given the 
highest yields. These varieties should be sown at the rate of 6 pecks 
per acre. 
White Smyrna and Hannchen are the highest yielding varieties of 
barley on the dry land. The barley should be sown at the rate of 
4 to 6 pecks per acre. 
Red Russian proso has given the highest yields in plat experiV 
ments, and the Turghai in nursery experiments. Seeding proso in 
ordinary drill rows at the rate of 25 to 30 pounds per acre has given 
the highest yields. 
Grain sorghums mature too late and require too much warm 
weather to be successfully grown at Newell. Manchu Brown kaoli-. 
ang is the most certain of the grain sorghums yet grown there. 
Damont (Select Russian) flax has given the highest yields. Re-^ 
serve (X. Dak. Xo, 155) is the next best variety. The best rate of 
seeding for flax on dry land is about 2 pecks per acre. Flax should 
be sown before May 15. 
The following varieties of grain are recommended for growing on 
dry land: 
Spring icheat. — Kubanka, Marquis. Barley. — White Smyrna, Hannchen. 
Winter icheat. — Turkey or Kharkof. Proso. — Red Russian, Turghai. 
Oats. — Kherson or Sixty-Day. Flax. — Damont. Reserve. 
On irrigated land the Kubanka variety has produced the highest 
yields of spring wheat. Of the common spring wheats Marquis is 
perhaps the best, although Power and Champlain have given slightly 
higher average yields. 
The hard red winter varieties. Turkey and Kharkof, are the best 
winter wheats for irrigated land. A selection from Turkey has 
produced the highest yields of the winter-wheat varieties. 
Kharkof winter wheat should be sown at the rate of 5 pecks per 
acre on irrigated land. The best depth of seeding winter wheat is 
about 1J inches. 
Winter wheat has yielded slightly more than spring wheat under 
irrigation. 
Spring emmer has yielded less than the best varieties of barley on 
irrigated land. Winter emmer and spelt are not hardv and give
