Commercial Varieties oe Oats Grown at High moor Farm 



in 1915. 



The Maine Agricultural Experiment Station has been con- 

 ducting tests of commercial varieties of oats at Highmoor Farm 

 since 1910. The detailed results of these tests for the four 

 years 1910 to 19 13 inclusive have been published in Bulletin 229. 

 The results of the 1915 tests are now available and show many 

 interesting points. 



The method used by the Station in recent variety tests has 

 been to plant four plots of each variety. Each plot contains 1-40 

 of an acre, making in all 1-10 of an acre devoted to each variety. 

 The four plots of a variety are placed in different parts of the 

 field so that the yield of any one variety is less likely to be 

 affected by differences in soil conditions. The average of the 

 four plots is taken as the yield of a given variety for that year. 



For a number of years past as many as 20 or more commer- 

 cial varieties of oats have been tested each year. Owing to the 

 necessity for testing upon a larger scale a number of new varie- 

 ties of our own breeding this year, it was necessary to decrease 

 the number of commercial varieties in the test. Eleven differ- 

 ent commercial varieties were tested in 191 5. The majority of 

 these were chosen because of their good yields in former years. 

 A few, like the Kherson and the Senator, were chosen because 

 they represent distinct types of oats. 



The yields with the varieties arranged in order of the 3 year 

 average yields are given in the table that follows.
