134 EXPERIMENT STATION RECORD. 



either earlier or later. Seeding 2 bu. per acre ])ro(UK-ed a heavier yield than 

 either smaller or larger quantities of seed. 



Monster winter rye grown for 3 years successively gave an average yield of 

 37.97 bu. per acre. Ivanof winter rye, a Russian variety, appeared a little 

 hardier and a stronger growing rye than Monster. The average yields for the 

 2 seasons, 1904 and 1905, were about the same. 



Of the varieties of winter oats tested at the station. Winter Turf seemed 

 more hardy than Virginia Gray, Common Gray, and Culbertson. In the fall 

 of 1904, 2 samples of Winter Turf oats were sown, the first yielding 57.37 bu. 

 and the second 44.05 bu. per acre, while on another field Red Texas oats yielded 



71.26 bu. per acre. The following year the winter oats winterkilled very badly, 

 only a few plants surviving. The seed from these was harvested for further 

 planting and the selection of hardier strains. The Winter Turf oats stooled 

 abundantly and made a rank growth of foliage. 



In experiments with spring wheat Velvet Don durvim wheat, as an average 

 for 4 years, yielded 14.24 bu. per acre, while the best producing variety of 

 winter wheat yielded 41.70 bu. The durum wheats yielded better than the 

 common varieties of spring wheat. 



The highest average yield during the 4 years' comparison of varieties of oats. 

 which was 43.24 bu. per acre, was produced by Sixty-day. and the second high- 

 est yield, 42.11 bu. per acre, by Kherson, two of the earliest maturing varieties 

 grown. Red Texas ranked third, with an average yield of 40.44 bu. per acre. 

 In 1905 and 1906 the average highest yields were as follows : Red Texas 54.37 

 bu., Silvermine 52.18 bu.. White Tartar 51.97 bu., Danish 48.03 bu., Kherson 



47.27 bu.. Sixty-day 40.75 bu., Minnesota No. 202 46.57 bu., and Swedish Select 

 45.16 bu. per acre. 



During the 4 seasons' work with varieties of barley. Common Six-rowed barley 

 made the largest average yield, 30.94 bu. per acre, Bonanza and ^lansury ranking 

 second and third, with yields of 28.97 and 28.80 bu. per acre, respectively. Beard- 

 less varieties produced smaller yields with a poorer grade of grain than varie- 

 ties of the six-rowed bearded tj'pe. Hulless barley produced relatively low 

 yields. In general, the largest yields from different rates of seeding barle.v and 

 oats were secured from the use of 2i bu. of seed grain per acre. The yields 

 of grain on brome sod land, however, were not only larger than those produced 

 on corn ground and alfalfa land but the largest crop was also secured from sow- 

 ing I2 bu. of seed barley per acre. The brome sod land pi'oduced nearly 25 bu. 

 more per acre than the alfalfa land and 11.3 bu. more per acre than the coi-n 

 ground. This result was largely due to the lodging of the grain where the crop 

 followed the alfalfa and corn. In 1905 the best j'ield of oats, as well as of 

 barley, was secured from seedings made March 30. In 1906 barley and oats 

 were sown on 7 different dates from February 1 to May 11. The largest yield 

 of barley, 36.55 bu., was produced by seeding February 1, but the largest yield 

 of oats, 43.75 bu., was secured from the seeding made March 29. The seeding 

 of different small grains on February ], February 19, and at the ordinary season 

 showed that spring wheat, emmer, and barley gave decidedly larger yields from 

 the early or winter seeding, while oats, winter wheat, and winter rye were most 

 satisfactory when sown at the ordinary season. 



Nitrate of soda was applied at the rate of 180 lbs. per acre for oats and 210 

 lbs. per acre for barley. The oats lodged badly on both the fertilized and 

 unfertilized plats. The fertilized plat produced 19.5 bu. of grain and 1,512 lbs. 

 of straw, and the unfertilized plat 24.4 bu. of grain and 1,649 lbs. of straw per 

 acre. The fertilized barley plat gave 20 bu. of grain and 2,234 lbs. of straw per 

 acre, and the check plat 16.2 bu. of grain and 1.640 lbs. of straw per acre. The 

 following year the experiment was repeated, nitrate of soda being applied to
