Manchu kaoliang does not tiller as freely as most of the grain sor- 

 ghums. The largest percentage of suckers produced was 49.5 per 

 cent, in 1910, when the plant space was 14.2 inches. This was one 

 sucker to each main stalk and reduced the stalk space to 7.1 inches. 

 The average height of this variety has been 5.1 feet and the variation 

 from 3.5 feet, in 1913, to 6.5 feet, m 1911 and 1915. 



The annual and average acre yields of leading Brown kaohangs 

 are brought together in Table XXXV, and the acre yields of the 

 leading varieties in all three subgroups are compared in Table XXXVI. 

 The 9-year average acre yield of Manchu kaoliang has been 21.2 

 bushels. This exceeds the yield of any of the kafirs or White durra, 

 but falls just below those of Alba milo and feterita. It is about 3 

 bushels below the average yield of milo and about 7 bushels below 

 that of Dwarf milo. Although this kaoUang failed completely in 

 1913, as did all the grain sorghums, it has given better yields in the 

 other dry years than most of the varieties. In 1916 its yield was 6.6
