OX-HORN VARIETIES 



359 



A common fault with some strains is their inclination to ' bolt ' 

 or behave as annuals, and produce an inflorescence the first 

 season without forming a thickened ' root.' 



Long Varieties. — In these the ' roots ' are three or four times 

 as long as they are broad {A, Fig. 114), and are generally about

a half or two-thirds above the soil. These varieties give the 

 greatest yield per acre of any kind of mangel, and are suited to 

 deep soils, especially clays and loams. They are divided into 

 (i) long red and (2) long yellow varieties, according as the skin 

 is red or yellow. 



The long yellow kinds are somewhat superior in quality to the 

 long red ones, but both are coarse and fibrous, and of lower 

 feeding value than most of the va,rieties mentioned below. 



Ox-horn Varieties. — These are very closely allied to the 

 long red and long yellow varieties, but their ' roots ' assume 

 a twisted horn-Uke shape. The part below ground does not 

 descend below the depth of the plough furrow : they are therefore 

 suited to shallower soils; but their irregular growth makes it
