The effect of hot weather cultivation and moisture conserva- 

 tion was then tried at Cawnpore and, as at Pusa, the effect was 

 instantaneous. The detailed results are published elsewhere, and 

 it is sufficient to say that crops of between 25 and 30 mds. to the 

 acre of high quality wheat have been produced using half the 

 quantity of irrigation water employed by the cultivators in the 

 neighbourhood. 



At this point it became desirable to determine the actual crop 

 increase resulting from hot weather cultivation. It was unfor- 

 tunate that both at Pusa and at Cawnpore all the land had been 

 thoroughly cultivated in the hot season for at least two years before 

 the experiment was started and none of the area had been left in 

 its original condition. Under these circumstances it was expected 

 that no great differences would be detected the first year, and that 

 it would take some time for the fertility to fall to the ordinary 

 level of that exhibited by the cultivators' fields. 



The experiment at Pusa was commenced after the harvest of 

 1910, and a level plot of typical wheat loam of high moisture re- 

 taining capacity was selected for the purpose. One half was cul- 

 tivated during the hot weather, the remainder being left untouched 

 till after the beginning of the monsoon. Across both plots a strip 

 of land was manured just before sowing with nitrate of soda at the 

 rate of 224 lbs. per acre and the results are shown in the following 

 plan : — 



The numbers in the table are bushels per acre.
