INTRODUCTION. 
The farmer who makes a success on high-priced irrigated land must 
not only grow large crops, but he must market these crops in the 
most advantageous way. Most crops grown in localities far removed 
from the large consuming centers should be marketed in condensed 
form, so as to reduce the cost of transportation. For example, a 
hundred pounds of butter can be shipped to market much more 
cheaply than the hay and grain required to produce this butter. The 
farmer should take advantage of this fact in organizing his opera- 
tions. In addition to this saving, the manure resulting from the 
feeding of the crops makes it possible to produce larger crops in sub- 
sequent years. 
1 The experiments reported in this bulletin have been conducted on the Scottsbluff 
Experiment Farm on the North Platte Irrigation Project in Nebraska. This experiment 
farm is conducted by the United States Department of Agriculture in cooperation with 
the State Experiment Station of Nebraska. The primary object of these experiments 
has been to determine the most efficient method of utilizing alfalfa, which is the most 
important crop on this project, as it is on nearly all of the irrigated projects of the 
West. The author desires to acknowledge the assistance given him by Mr. Henry Sullivan 
in carrying out the details of the experiments.— -C 8. Scofield, Agriculturist in Charge,
