The former are marked A and the later are marked B. 

 The figures in parenthesis after A or B, indicate the number of 

 applications. 



From the above table, we see that the growth of seedlings which 

 have the base manure, are remarkable good except those have Ammonium 

 and night soil given in four times; rape-seed cake given in one time to 

 Sugi; Chili saltpetre given in one time; and the rape-seed cake given in 

 one and two times to Hinoki. 



IV. Comparative Efficacy of Different Fertilizers 



The scope of the experiments was to establish the appropriate time 

 of manuring of principal nitrogenous manures used in this country 

 of Sugi and Hinoki seedlings. Comparison was also made of the 

 eflScacy of the ordinary nitrogenous manures upon these species. The 

 average weight and length of seedlings and the quantity of nitrogen 

 absorbed in each lot after 2 years planting are given in the following 

 table.
