1 Destroyed by hail. 2 The yield from this plat is omitted, owing to an error in time of seeding. 



The cost of production and the value of the crop as here computed 

 show a profit by all methods under trial. The profits range from 98 

 cents by summer tillage to $7.24 on disked corn ground. 



HUNTLEY FIELD STATION. 



The records of only two years of yields under four different methods 

 of treatment are available for study from Huntley, Mont. In 1913 

 there was little difference between spring-plowed oat stubble and 

 disked corn ground as a preparation for barley. In 1914 disked corn 

 ground was markedly the better of the two. The heaviest yields 

 each year were obtained from land on which peas were plowed under 

 for green manure. In 1914 there was a marked increase in the yield 

 on ground on which rye was plowed under. In preparation for 1913,
