CKOP PRODUCTION IN" THE GEEAT PLAINS AEEA. 27 



grain crop. As a feed crop, which includes the utilization of both 

 roughage and grain, it can be profitably grown in all sections north 

 of the southern line of Nebraska and in eastern Colorado. In the 

 northern portions of western Kansas it will compete with the sorghums 

 as a feed crop. South of central Kanass some of the sorghum crops 

 have been more profitable than corn. 



Milo and kafir for both grain and feed are well adapted to conditions 

 in western Kansas, western Texas, Oklahoma, and eastern New 

 Mexico. 



CONCLUSIONS. 



These investigations furnish strong presumptive evidence upon 

 which to base the following conclusions : 



(1) When the climatic conditions are -as favorable as those often 

 experienced in all parts of the Great Plains area on all the types of 

 soil represented at the 14 stations, profitable crops can be produced 

 by any one of several different cultural methods such as are in com- 

 mon use. 



(2) When the climatic conditions are as unfavorable as those often 

 experienced in all parts of the Great Plains area on any of the types 

 of soil represented, no profitable crop of any kind so far tested can be 

 produced by any of the cultural methods that have been under 

 investigation. 



(3) Under the normal conditions prevailing in any part of the Great 

 Plains for a term of 10 years on any type of soil represented at any of 

 the stations, some crops can be produced at a profit when proper 

 cultural methods are practiced, provided that the prices of labor and 

 of farm produce bear the same relation to each other as those which 

 have prevailed there during the last 10 years. 



(4) No single crop tested in these investigations can be raised 

 profitably in all parts of the Great Plains area on any type of soil by 

 any rultural method so far tested. 



(5) As forage crops of some kind can profitably be grown at all 

 stations, they must occupy an important place in any system of farm- 

 ing adapted to the Great Plains. Sufficient live stock must be kept 

 to converl these crops into finished products on the farm, and suf- 

 ficient forage must be produced and stored during favorable seasons 

 to carry the live stock through specially unfavorable seasons. 



(6) (iood farming is as essential to success in the Great Plains 

 area :i- elsewhere, (iood farming means practicing the l>est methods 



of producing the largest crops at the lowest, relative cost of production 



and Leaving the 3oil in die best condition for the production of subse- 

 quent crops. Good farming may involve' methods either intensive 

 or extensive, eii her expensive or inexpensive; and it must be practical 

 and economical as well as scientific and thorough in order to be good 



funning. It is just, ;is poor farming to go to too much expense as it
