 VARIETAL TESTS. 



The acre yields in bushels obtained in varietal tests of wheat at 

 Brookings, Highmore, Eureka, and Cottonwood are shown in Table 

 III. The results for eight years (1905 to 1912) are given for Brook- 

 ings and Highmore and for four years (1909 to 1912) in the case of 

 Eureka and Cottonwood. These yields were produced without fer- 

 tilizers and without systematic rotation, the method being strictly 

 comparable to that in use by the majority of farmers. Any gain in 

 yield over the average for the State may be ascribed to the producing 

 power of the variety, to well-cleaned seed, and to good tillage rather 

 than to fertilization or good rotation methods.
