THE DISTRICTS STUDIED. 1 
In 1915 and 1916 a study was made of the farm practice in growing 
sugar beets in three districts of Colorado. These data were published 
in Department Bulletin 726. In the summer of 1918 these districts 
were revisited and data obtained for the 1917 farm year, showing 
the farm practice and labor requirements in handling the crops 
grown in rotation or in competition with sugar beets. 
It is believed that this information will show not only the com- 
parative requirements of labor, materials, etc., for the various crops, 
but also how these crops fit into the rotation system in these areas. 
An attempt has been made to present the comparative cost of 
producing these crops. Many items of cost in 1917 were abnormal, 
but as many of these enter into the production of all crops, the 
opportunity for comparison remains the same. 
The data presented were worked out from 328 records. The dis- 
tribution of these among the various crops is shown in Table I. 
1 Acknowledgment is due to Miss Catherine Hawley, of the Office of Farm Management and Farm Eco- 
nomics, for careful work in supervising the tabulations which have been used in this bulletin. Thanks 
arealsodue the farmers of these districts for their hearty cooperationin giving complete estimates concern- 
ing the man and horse labor requirements and other costs of producing the crops included in this study.
