are given in Table II. The sample of grain was a very, 

 fine one with the uniform texture which millers so much 

 appreciate.

Yields obtained with Pusa 12 at Shahjahanpur with one irrigation,. 



1918-19. 



Taking all these results together, two principles stand 

 out clearly. In the first place, it is evident that a fair 

 wheat crop in North- West India can be obtained under 

 ordinary conditions and on ordinary land by means of the 

 preliminary irrigation only. In the second place, if the 

 texture of the soil has been improved and if the surface 

 has been properly graded (as was the case in the Quetta 

 and Shahjahanpur experiments of 1918-19) the duty of 

 water is very greatly increased and extremely heavy crops 

 are possible with a comparatively small volume of irriga- 

 tion water. Further waterings in these two experiments 

 would have produced no useful result as the grain in both 

 cases was well filled and the yield had already reached the 

 limits imposed by the standing power of the varieties 

 grown. The establishment of these two principles leaves 

 no doubt as to the main direction of improvement in wheat 

 production in North- West India. A portion of the wheat 

 and gram grown should be raised on the preliminary irri- 

 gation only supplemented by the winter rains or at the 

 most by one additional watering. The water thus set free 

 should be used for the production of leguminous fodder
