CORN IN" THE GREAT PLAINS AEEA. 31 



A careful reading of the data given in the table will show that corn 

 as a grain or cash crop can not be profitably grown in large portions 

 of the Great Plains. At only 5 of the 13 stations have the grain 

 yields been sufficiently large to indicate a possibility of the crop 

 being profitably produced for the grain only. At Huntley, Dickin- 

 son, Scottsbluff, North Platte, and Akron enough grain was pro- 

 duced by some methods to pay the cost of production and show 

 small profits. Taken as a whole, however, the data show that, in 

 order to realize the full profit, the corn should be considered as a feed 

 crop. To pay the cost of production in many sections, it is neces- 

 sary to utilize the roughage produced. 



CONCLUSIONS. 



(1) No one method of seed-bed preparation is essential to the pro- 

 duction of corn in the Great Plains. 



(2) Differences in seed-bed preparation, other than summer till- 

 age, have not produced wide differences in grain yields, except at 

 Huntley, Mont. 



(3) Summer tillage has slightly increased the grain yield at all 

 except three stations and has materially increased the fodder yields 

 at the three southern stations. The increase in yields, however, has 

 not been sufficient to make it the most profitable method at any 

 station except Scottsbluff. 



(4) At some of the stations, especially at North Platte and Akron, 

 crop sequence is more important than seed-bed preparation in the 

 production of corn. 



(5) At 8 of the 13 stations corn as a grain crop has not been pro- 

 duced at a profit by any method. 



(6) When a value of $4 per ton is assigned to the stover or fodder, 

 corn has been profitably grown by some method at all but one of 

 the stations. 



(7) The response to differences in culture and crop sequence is 

 greater in the southern and central portion of the Great Plains than 

 it is in the northern portion.
