CEREALS ON THE BELLE FOUECHE EXPERIMENT FARM. 7l 



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 experi' 

 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 (N. Dak. No. 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 wheat. — Kubanka, Marquis. Barley. — White Smyrna, Hannclien. 

 Winter wheat. — Turkey or Kliarkof. 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 1^ 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 hardy and give
