These results show that there is no increase in the outturn by 

 using larger amount of phosphoric acid. These experiments may 

 therefore be discontinued. 



12. Top-dressing for sugarcane. To compare the value of 

 different nitrogeneous manures, including mineral manures, a 

 series of five plots was manured last year with 200 Ibs. of nitrogen 

 in the form of farmyard manure and 150 Ibs. nitrogen in the 

 form of various top-dressings, plot 1 receiving all nitrogen 

 from farmyard; manure in the beginning. 



This year the dressing given to these plots was similar to 

 that of the last year's top-dressings, but only 233J Ibs. of 

 nitrogen per acre was supplied. Plot 1, which received only one 

 application of farmyard manure last year, received the same 

 dressing as the second plot and the residual effect of the farm- 

 yard manure will be observed. 



The results with the outturn of the last year are tabulated 

 below for comparison.
