crops. In high mountain valleys, however, clover suc- 

 ceeds well under irrigation, notably in the Gallatin Valley, 

 Montana, but similar success has been had in several 

 Western States, either when sown alone or mixed with 

 timothy. 



King in Wisconsin tested irrigation on red clover. 

 Where the plots were irrigated twice after the first cutting, 

 the second cutting was over two tons to an acre as against 

 one ton where not irrigated. Irrigation after the second 

 cutting also increased greatly the fall pasturage. With 

 an optimum amount of water, either rain or irrigation, 

 King concludes that the clover crop may be double what 

 is ordinarily secured. 



443. Red clover in mixtures. Much more red clover 

 is sown in mixture with timothy than in any other way, 

 approximately three-fourths of the total acreage being 

 thus sown. The timothy is commonly sown with wheat 

 in fall, and the clover added in the spring. 



In this mixture the crop is mainly clover the season after 

 sowing, but thereafter is mainly timothy. An objection 

 to this mixture is that medium clover matures sooner 

 than the timothy, but this may be avoided by using the 

 mammoth variety. Red clover and alsike are also fre- 

 quently sown together, especially where there is difficulty 

 in securing a stand of the former. 



Other grasses suitable to grow with red clover are 

 orchard-grass and tall meadow oat-grass, but these mature 

 somewhat sooner. In complex grass mixtures, which are 

 more popular in Europe than in America, red clover should 

 always be included. 



444. Use in rotations. The characteristics of red 

 clover make it particularly well adapted to use in rotation 

 with other crops. Various such rotations are possible,
