EXPERIMENTS AT ROTHAMSTED 



75 



TABLE XXL 



PRODUCE OF TARTAR OATS WITH VARIOUS MANURES AT 

 ROTHAMSTED. AVERAGE OF FIVE YEARS, 1869-73. 



In Table XXI we find that the best result was given 

 by the ammonia salts when they were used in conjunction with 

 superphosphate and alkali salts ; not only is the produce of 

 corn and straw much larger under these circumstances, but the 

 quality of the oats, as shown by the weight per bushel, is also 

 much the best. We have seen similar facts already in the 

 wheat and barley experiments. 



TABLE XXII. 

 PRODUCE OF TARTAR OATS WITH VARIOUS MANURES AT 



ROTHAMSTED. 

 AVERAGE OF FOUR YEARS 1874-6 & 8. 



As in the experiments with barley, the 200 Ibs. of ammonia 

 salts proved a more economical dressing than the 400 Ibs. 

 With 200 Ibs. of ammonia salts, used \vith superphosphate 

 and alkalies, we have an average return of 13-3 bushels, or 



'Equal to 11-2 bushels of 421bs. weight. 

 **Equal to 64 bushels of 421bs. weight.
