BULLETIN 698, U. S. DEPARTMENT OF AGRICULTURE. 



about eight days in favor of the Dawn, which gives it about the 

 same earliness as Sunrise kafir. In some seasons this difference 

 was reduced to 1 or 2 days. In 1914, a dry year, and in 1915, a wet 

 year, the difference was increased to 13 or 14 days. In 1916, a very 

 dry year, the Dawli headed about 10 days ahead of the standard 

 kafir and produced some grain, but the standard produced no grain 

 whatever.

In the matter of germination and stand, the Dawn kafir has been 

 comparable to the ordinary Blackhull kafir and to the Sunrise kafir. 

 In 1908, the plant space was 14.1 inches and in 1910, a dry spring, it 

 was 22.9 inches. The average spacing in the entire period of nine 

 years was 11.4 inches, which is about 1 inch closer than that of 

 Blackhull kafir, but is about 2 inches wider than that of Sunrise 

 kafir. The final stand, or original stalks plus suckers, has been 

 good. The average stalk space is 6.1 inches, compared with 7.6
