Basu, Assistant to the Department of Land Records 

 of Agriculture, on the Dumraon Farms. Writing in 

 the Agricultural Ledger, No. 10, of 1893, he gives 

 the result of five years' experiments : With no 

 manure the average crop of wheat was 10 maunds 

 (820 Ib.) per acre ; with manure, in the form of 

 3 maunds of saltpetre (supplying nitrogen) per acre, 

 the average result was 19 maunds per acre. It 

 must be noted, however, that saltpetre is not a 

 complete manure, and will exhaust the soil unless 

 other manures are added, and this is shown by the 

 continuous reduction in the crop during the five 

 years of the experiment. The first year of the 

 application of saltpetre the crop was 27 maunds per 

 acre, in the last year it was a little over 15 

 maunds. 



On page 376 Mr. Kenny quotes the results obtained 

 in England at Rothamsted. After seventy years 

 without manure the land continued to produce 

 from 10 to 15 bushels of wheat per acre, each bushel 

 weighing 60 Ib. With 14 tons of farmyard manure 

 the production is 33 bushels. 



Mr. Kenny writes at some length to show the 

 need for manure in growing sugar-cane, tobacco, 

 tea and coffee. In dealing with coconut trees, 

 on pages 504 and 505, he quotes the owner of an 

 estate as saying that he has raised the average 

 crop from 10 nuts per tree to 135 nuts by careful 

 manuring. 



In dealing with potatoes on page 567, Mr. Kenny 

 quotes the Annual Report of the experimental
