jowari in the Dharwar Taluka, a series of comparative 

 experiments was conducted on a large number of plots 

 for a period of twelve years, and the result was to show 

 that a dressing of farm-yard manure, to the extent of 

 5 tons per acre, applied every alternate year to jowari, 

 in the two-year rotation of cotton and jowari, gave an 

 average additional outturn as follows : — 



Jowari ..... 265 lb. 



Kadbi (jowari stalk) . . . 843 ,, 

 Seed cotton . . . . 49 ,, 



The value of this additional outturn is about Bs.40, 

 and as the cost of the manure required to produce it is 

 only Es.15, it is clear that this investment yielded a 

 very good profit. Looked at from another point of 

 view, these experiments show that the outturn of 

 jowari and kadbi can be increased from 25 per cent, 

 to 30 per cent., and the outturn of cotton by 10 per cent, 

 by the application of 5 tons of manure every other 

 year. As alternatives to farm-yard manure town 

 sweepings and pouclrette * were tried, and were found 

 to give very similar results, the former being rather 

 inferior to farm-yard manure, and the latter markedly 

 superior. They are available only in the neighbour- 

 hood of towns of some size. In another series of 

 experiments conducted in the same farm on many 

 plots during a period of twelve years, to determine 

 the best dressing of farm-yard manure for the land, 



*This substance is the product of scavenging mixed with dry 

 earth.
