EXPERIMENT STATION BULLETINS. 



66'; 



The old standard oats (Alexander) has averaged 64.7 bushels for the 

 past six years and the new standard oats (Success) has produced 75.5 

 bushels per acre for the past four years. No spring barley has yielded 

 as much as 40 bushels per acre, on a three-year average. Thus it can 

 be clearly seen that not only the large number of poor yielding varieties 

 of barley that Michigan is growing, but the best spring barley that this 

 investigation has been able to find, is producing less feed per acre than 

 the high grade varieties of oats. 



TABLE I.— YIELD TEST 1912-1915. 



From the above table all strains or varieties of barley that yielded less 

 than Oderbrucker have been omitted. The highest yielding Oderbrucker 

 is taken as 100% in the table, and the other varieties compared with it 

 from year to year. The general average shows that Michigan Winter 

 is about one and three-fourths times as productive as Oderbrucker, while 

 the Derr Winter yields a half more. In the last column may be seen the 

 number of bushels per acre in excess of the yield of the Oderbrucker. 



WINTER BARLEYS. 



The work with winter barleys began with Mr. H, B. Derr's selections 

 for testing in this section. They were planted in the fall of 1909 in beds, 

 i. e., a single seed in a place five inches apart from its neighbor. Two 

 of the eight lots winter-killed as a whole the first season. A third lot 

 M^as injured enough to be proven distinctly inferior, and was discarded 

 as a whole. 



Eight selected plants were saved out of the remaining five sources to 

 become mothers of plant-rows planted in the fall of 1910. In 1911, two 

 of these strains (all that remained from another of the sources) were 

 discarded, as they had been injured by the winter. This left six strains, 

 from four of the original sources, to be tested by the winter of 1911-1912. 

 The fall rains soaked the ground before freezing and the temperature 

 reached 30° below. This was a testing time that the weather man tells 

 us has not been repeated since 1884. A very large portion of the wheats 

 in Southern Michigan were killed or badly injured that winter, and 

 most of the wheats in the Michigan Station's variety series were badly 

 injured. The six strains of winter barley were tested that winter along 

 with the wheats, and as a result all of the strains of another source (the 

 Wisconsin Winter barley) had disappeared. This left a strain of barley
