has been the highest yielder. The percentage average yield of Peru 
(C. I. No. 653), a variety almost identical with Coast, was 100.2, while 
that of Trebi, also a six-rowed variety, was 102.2. 
The percentage yield of Maryland Winter in the three years from 
1911 to 1913 was 138.2, and that of Wisconsin Winter in the two 
years 1911 and 1912, was 107.8. The high yields of the former in 
1911 and 1912 and of the latter in 1912 are abnormal and are not 
considered comparable with those of other varieties grown in these 
years. The highest yielding two-rowed barley was White Smyrna, 
whose percentage was 92. Club Mariout has produced a yield of 
91.8 per cent of that of Coast in a 10-year period. During the past 
four years it has compared very favorably with Coast. 
The six-rowed hulled varieties are best adapted to this section, 
particularly those of North African origin, which includes the barleys 
of the Coast type. The two-rowed hulled barleys yield fairly well 
but none has equaled Coast. The six-rowed naked or hull-less 
varieties tested have produced about 15 per cent less grain in pounds 
per acre than Coast. The hooded varieties have been comparatively 
low in yield.
