out yielded the Lincoln variety. The two arc very close together, 

 however, and another year or two will possibly decide which one is 

 better adapted to New York conditions. 



When the average yield of the best eight selections for the three 

 years is compared with the average yield of the eight unselected vari- 

 eties, there is a marked difference in favor of the selections. The 

 average yield of the eight selections is 61.5 bushels per acre, while 

 that for the eight commercial varieties is 53.1 bushels per acre. The 

 average for the eight new strains is higher than the yield of any one 

 variety except the Lincoln. The average weight per bushel of the 

 eight selections was 30.31 pounds, while that of the commercial varie- 

 ties was 29.75 pounds. 



TESTS AT VARIOUS OTHER EXPERIMENT STATIONS. 



INTRODUCTION. 



At various times from 1907 to 1910, seed of certain of the selections 

 from hybrids and commercial varieties discussed in this bulletin was 

 sent to a number of the State experiment stations. In addition to 

 the data already reported from the Iowa and Cornell University sta- 

 tions, where the principal tests were conducted in cooperation with 

 the Bureau of Plant Industry, valuable data have been obtained and 

 are here reported from the Pennsylvania, Virginia, Ohio, Indiana, 

 Kentucky, Tennessee, and Minnesota agricultural experiment sta- 

 tions. The results of tests at the Arlington Experimental Farm in 

 Virginia are also included. 



PENNSYLVANIA.! 



Twenty selections which were believed to be adapted to the local 

 conditions were sent to the Pennsylvania experiment station in 1910. 

 These strains were tested on a Hagerstown clay-loam soil in a good 

 state of fertility. In 1910 and 1911 the oats followed potatoes in a 

 rotation of potatoes, oats, wheat, and clover and timothy; in 1912 

 they were grown in a similar rotation hi which corn replaced the 

 potatoes. In each of the first two years 160 pounds of acid phos- 

 phate to the acre were applied to the oats; in 1912, 320 pounds were 

 used. The 20 strains were grown in 1910 in rows 60 feet long and 

 14§ inches apart, made by sowing from alternate holes in the grain 

 drill. In 1911 and 1912, owing to lack of land, only the most prom- 

 ising strains were grown. The plats were 139 by 5.5 feet in 1911 

 and 150 by 5.5 feet in 1912. The rate of seeding was 9 pecks to the 

 acre. 



The only strain which exceeded the check variety Japan in yield 

 for the three years was a selection of the Sixty-Day, 62— II— 18— 1 — 1 ,

 the results here reported.
