SUGAR CANE. 



Sugar cane, variety Cristalina, was grown 148 days, which is about 

 one-third of the time necessary for maturity. At the end of this 

 period stallcs were forming but practically no leaves had withered. 

 The figures in Table X\1I give the weights of the whole plants, loaves 

 and stalks unseparated. 



Table X"\'II. — Growth of sugar cane on plats with different amounts of Ca<''0:^. 



On the average the growth of Plat II was practically equal to that 

 on Plat I, but there was a decrease of 21 to 27 per cent on Plat III 

 and a probable decrease on Plat IV of 2 to 20 per cent. 



Since the cane when cut had short, poorly defined stalks, only the 

 leaves were used for analysis. Crop A was analyzed alone, and crops 

 B, C, and D were analyzed together in a composite sample. The 

 results are given below.
