POT EXPERIMENTS WITH FERTILIZERS. 



i6r 



The average weight of the crop was the same on the pots 

 with the different quantities of nitrogen, but was smaller on 

 the pots with the mineral fertilizers alone. The percentages 

 of protein in the crops increased steadil}- with the increase in 

 the amount in the fertilizer, the average percentage in the crop 

 with the full ration of nitrogen being more than twice that in 

 the crop from the pots with no nitrogen. This is a striking 

 illustration of the advantage of nitrogen as fertilizer for in- 

 creasing the feeding value of such a crop as Hungarian grass. 



EXPERIMENT WITH BARN YARD MILLET. 



The experiment with barn yard or Japanese millet included 

 pots 33 to 48. The results of the experiment are given in 

 Table 79.
