excellent milling quality. The Marquis was one of the few varieties 

 which matured grain in 1912, while in 1913 it produced a slightly 

 higher yield than any other variety of Fife wheat grown at Newell. 



The bluestem wheats, another of the important groups of hard red 

 spring wheats, have given rather poor yields at Newell. The only 

 variety which has been grown for the entire six years is the Haynes, 

 C. I. No. 3020. This variety is also known as Minnesota No. 169. 

 The bluestem wheats have beardless heads, with hairy, white chaff. 

 They mature slightly later than the Fife varieties, and for that reason 

 probably have not given as good yields as the latter. 



The only other group of common spring wheat of importance in 

 western South Dakota is the Preston (bearded Fife). The varieties 

 of this group have been grown only two years — 1912 and 1913. In 

 1912, in common with practically all other wheat varieties, they 

 produced no grain. In 1913 they produced higher yields than any of 

 the other common wheats. The Preston, C. I. No. 3081, produced the 

 highest yield of any variety under trial that year, including the 

 durums. One or two varieties of the Preston group appear to be 

 worthy of further trial. 



RATE-OF-SEEDING TEST OF SPRING WHEAT. 



A rato-of-seeding test with Kubanka durum wheat was conducted 

 in 1909, 1910, 1912, and 1913. The seed, the preparation of the 

 ground, and the date of seeding have been identical for all plats. In 

 1909 and 1912 this test was conducted on land which was fallow the 

 previous year. In 1910 it followed corn and in 1913 was on land 

 which produced a very small crop of wheat the preceding season. 



In 1909 and 1910 single tenth-acre plats and in 1912 and 1913 three 

 fiftieth-acre plats were sown at each rate. The rates varied from 2 to 

 8 pecks per acre, but only the 4, 5, 6, and 8 peck rates were sown in 

 each of the four years. Table XI shows the annual and the average 

 yields of grain and of straw from the different rates of seeding.
