II. The Influence of IiInvironment on Guain 

 Quality. 



Six Pusa wheats were employed in the environment experiments 

 of 1911-12. Three of these (Nos. 4, 12, and 22) are selections and 

 three (Nos. 107, 108, and 110) are hybrids. All are white wheats 

 of good quality and would be described as strong, free milling sorts. 



The fourteen stations at whicli these wheats were grown are 

 representative of the general agricultural conditions of the Indo- 

 Gangetic plain and of the soils of Central India. These stations, 

 which are indicated on the map at the end of this paper, were as 

 follows : — 



Stations on the Gangetic Alluvium. 



1. Pusa. This station is situated on the older alluvium in 

 North Bihar, a tract in wliich wheat is grown without irrigation 

 on high moisture retaining loams containing about 30% of calcium 

 carbonate. 



2. Partahfjarh. This station represents the alhivinl tract of 

 Oudh where wheat is chiefly grown on well-irrigation. 



3. Caw)ipor(i. This centre is typical of the wheat trnct known 

 as the Middle Doab, where wheat is grown on strong alhivinl loams 

 with canal irrigation. 



4. Meerut and Alujarh. These are duplicate stations, typical 

 of the large alluvial canal irrigated tract known as the Upper Doab, 

 where wheat is an important cold weather crop. The agricultural 

 conditions at these two centres closely resemble those of the neigh- 

 bouring Muzaifarnagar District.
