CROP PRODUCTION IN THE GREAT PLAINS AREA. 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 Kan ass 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 cultural 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 convert 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) Good farming is as essential to success in the Great Plains 
area as elsewhere. Good farming means practicing the best methods 
of producing the largest crops at the lowest relative cost of production 
and leaving the soil in the best condition for the production of subse- 
quent crops. Good farming may involve methods either intensive 
or extensive, either expensive or inexpensive; and it must be practical 
and economical as well as scientific and thorough in order to be good 
fanning. It is just as poor farming to go to too much expense as it
