III. THE INFLUENCE OF ENVIRONMENT ON GRAIN 



QUALITY. 



A. The eesults obtained in 1909-10. 



In this section the results obtained by growing the same wheat 

 at different stations and comparing the produce are dealt with. 

 During the season 1909-10, two wheats were grown at the ten 

 stations referred to below and complete milling and baking tests 

 were made in all cases. The two wheats selected were MuzafTar- 

 nagar white, (T. vulgare Vill. var. graecum Kcke.) a weak, soft, 

 white wheat from the MuzafTarnagar District in the United Prov- 

 inces and Pusa 20, a pure line selected from a Bengal durum 

 wheat, (T. durum Desf. var. apidicum Kcke.) The experiments 

 with MuzafTarnagar white are in continuation of those described 

 in the previous paper, and the seed sown at each station was taken 

 from the crop of the previous year grown at that station. In the 

 case of Pusa 20 the seed was taken from the bulk grown at Pusa. 

 The ten stations at which these wheats were grown were : — 



1. Pusa. This station is situated in North Bihar, a tract 

 in which wheat is grown without irrigation on high moisture 

 retaining loams containing about 30% of calcium carbonate. 



2. C awn f ore. At this station, which is typical of the im- 

 portant wheat tract known as the Middle Doab, wheat is grown on 

 strong loams with canal irrigation. 



3. Partabgarh. This station represents the wheat growing 

 tracts of Oudh where the crop is grown on well irrigation. 



4. Meerat. This station, where the samples were grown by a 

 local zemindar in the country fashion, is typical of the large wheat 

 growing tract of the Upper Doab and is practically identical with 

 the neighbouring MuzafTarnagar District.
