given results very similar in effect to those obtained at Hadlow, 

 allowing for the fact that the crops grown in Germany are on the 

 average much smaller than ours. 



The German experiments have been carried out for several years 

 running, on a similar plan, on twenty-one different hop plantations 

 in various parts of the hop growing districts. The results for the 

 three years (1900-1902) are shown in the following table, in which 

 the original figures (which, according to Continental custom, are 

 stated in kilogrammes per hectare) have been calculated into their 

 equivalents in cwts. per English acre : 



RESULTS OF EXPERIMENTS DURING THREE YEARS (1900-1902) ON 

 TWENTY- ONE HOP FARMS IN GERMANY, COMPRISING IN ALL 



SIXTY-THREE EXPERIMENTAL CROPS. 



It should be stated that both of the nitrate of soda plots above 

 mentioned were in every experiment duplicated, one-third of the 

 nitrate in one case being supplied in the autumn, while in the other 

 case all the nitrate has been applied in the spring. On the whole a 

 slight advantage is shown by giving a part of the nitrate in the 

 autumn, but it is to be remembered that nitrate so applied is in 

 danger of being lost during a wet winter. 



In this German investigation the quality of all the samples grown 

 at the various centres in each year appears to have been carefully 

 examined, the result being to show that on the average the best 

 samples were those grown on the plots giving the heaviest yields 

 namely, those manured with phosphates, potash salts, and 5^ cwt. of 

 nitrate of soda per acre.
