When considering these results we should take into account 
that the season of 1890 was very favorable to the development 
of rice and that the crops when they were cut had attained a 
normal maturity with the only exception of the plots which had 
not been manured with phosphoric acid ; on the latter the straw 
was still green at the time of harvesting. 
In the above table on the composition of the straw we notice 
some differences in proportion of crude protein and ash. The 
largest content of crude protein is found in the straw produced 
by means of a rich nitrogenous and potassic manure from 
which much nitrogen entered the plants but could not be fully' 
used up for the production of organic matter because of the 
deficiency of phosphoric acid ; the lowest proportion exists in 
the straw raised without any nitrogen in the manure because 
in these plants the insufficient quantity of nitrogen consumed
