that the group of farms having an average of 44.8 per cent of the field- 

 crop area in legumes was operated 2.21 times as efficiently as the 

 group of farms that grew no legumes. 



PERCENTAGE OF FIELD-CROP AREA IN CLOVER. 



Table VI shows the influence of all legumes collectively on the 

 returns of the silt-loam farms. Table VII is confined to a single 

 legume — clover. Of the legumes gro-wu on these farms, clover is by 

 far the most important, with vetch occupying second place. 



Table VII. — Relation of percentage of field-crop area in clover to percentage farm income 

 is of capital on 144 silt loam farms in Marion and Polk Counties, Oreg. {1912).

The iftiportance of the clover crop is shown in Table VII. Of the 

 144 farms, 61 grew no clover in 1912. Forty-five farms had an 

 average of 11.1 per cent, and 38 farms had an average of 32.7 per 

 cent of the field-crop area in clover. The average farm incomes of 

 these three groups of farms were 5.06, 6.96, and 8.63 per cent, respec- 

 tively, of the capital invested. The 38 farms having an average of 

 32.7 per cent of the field-crop area in clover were 1.71 times as 

 efiicient as those havino; no clover. 



CLOVER-SEED PRODUCTION. 



Table VIII shows that clover seed was a very profitable crop in the 

 Wniamette VaUey in 1912. The average yield per acre on the 54 

 farms that produced clover seed was 286 pounds for the first crop 

 and 108 pounds for the second crop. The average price received for 

 clover seed was 14.67 cents. The 3delds and prices are averages for 

 both red and alsike clover for the year 1912.
