MILLET AND PROSO 



These plants are remarkable in that they outrank all others so far 

 tested as regards efficiency in the use of water (Table XVII). The four 

 varieties grown at Akron in 191 2 gave the following water requirement, 

 based on the production of dry matter: 



Variety of millet or proso Water requirement 



Kursk millet iS7±2 



Voronezh proso 206 ± i 



Tambov proso 2oS± i 



German millet 248±7 



Kursk millet (PI. Y, fig. 3) represented by a strain developed by 

 Mr. A. C. Dillman, of the Office of Alkali and Drought Resistant Plant 

 Investigations, gave the lowest water requirement so far recorded for 

 any crop at Akron. The two prosos, Tambov and Voronezh (PL V, 

 fig. 2), have a water requirement about 10 per cent higher than the 

 Kursk, while German millet is 33 per cent higher than the Kursk. Aside 

 from the German millet, all of the varieties tested have a water require- 

 ment distinctly below the best of the sorghums, the group ranking next 

 in efficiency.
