64 FORAGE CROPS IN DENMARK 



although several samples were bought in the following years 

 from the same firm, none of these came up to the standard of 

 the first-class strains of Danish Swedes. 



Between 1900 and 1908 thirty samples of Mangels were 

 bought from Great Britain, France, and Germany, 1 and their 

 yields of solids in cwts. per acre were found by cultivating in 

 the usual manner. For the sake of comparison the average 

 yield of solids, in cwts. per acre, of the first class of Danish 

 strains for the year in question is taken as unit and called 100. 

 The average yield of the 30 foreign samples of mangels for 

 these years was found to be only 89*2, or nearly 11 per cent, 

 below the yield of the Danish strains. The samples from Great 

 Britain averaged only 86*1, or nearly 14 per cent, less than 

 Danish first-class strains, the lowest giving 80'4 and the highest 

 (2 samples) 91'5 per cent, of the yield of Danish first-class 

 strains. The foreign samples yielded about the same as Danish 

 strains of Class III. 



Similarly for Swedes. Nineteen foreign samples were tried 

 during the years 1900-1909, all but three being from Great 

 Britain. The average yield of these was 89'5, or 10*5 per cent. 

 below the average for first-class Danish strains of Swedes, the 

 lowest being 81*7, the highest the Scottish Bangholm, in 1900, 

 102*8. On the average the foreign Swedes yielded, when grown 

 in Denmark, only as much as Danish strains of Class III. In 

 1 91 4-1 6 2 four more British samples of Swedes were tested, 

 yielding from 87 to 89 per cent, of the yield of the Danish strains 

 of Roman figure V. 



With some justification Helweg advised Danish farmers not 

 to buy seed of foreign roots before these had been tested in the 

 Danish Competitions.
