1 Additions were made to the work at this station in the spring of 1909. The number of plats shown in 
the average is the number from 1909 to 1913, but it is not in all cases correct for 1907 and 1908. 
The yields of oats following rye plowed under for green manure 
have averaged practically the same as those on summer-tilled land. 
The yields following peas as a green manure have not averaged
