Barley is an important crop in southern Idaho as feed for stock. Several varie- 
ties that have been grown successfully at this substation have been distributed 
to farmers in the vicinity. The cultivation of one of these, Trebi (C. I. No. 
936), has spread over a considerable area in the Snake R.iver basin. The annual 
yields of the barley varieties grown in plats under irrigation from 1913 to 1921, 
inclusive, at Aberdeen, are shown in Table 67. These yields were obtained in 
cooperation with the Idaho Agricultural Experiment Station. While a number 
of ecological groups have been represented in these experiments, the varieties 
of the humid groups were not grown for a sufficient number of years to justify a 
group digest. 
In the summarized digest of Table 67 12 important or representative varieties 
are compared. Trebi (C. I. No. 936) is undoubtedly the best of these. During 
the eight years in which it was grown it produced an average acre yield more 
than 5 bushels higher than that of Beldi Giant (C. I. No. 2777), its nearest 
competitor in those years. Trebi is a selection made from a bulk importation of 
barley from Samsun, Asiatic Turke^^ From its behavior in southern Idaho it 
seems probable that it was originally grown under irrigation in one of the small 
vallej'^s south of the Black Sea. Following Trebi are two North African barlevs 
of the Coast group, Beldi Giant (C. I. No. 2777) and Sandrel (C. I. No. 937). 
Both of these have proved to be high-yielding sorts at a number of the western 
stations. 
Hannchen (C. I. No. 531) , a 2-rowed sort, is fourth in point of yield. Hannchen 
is one of the few 2-rowed spring varieties that has produced high yields in the 
Western States, particularly in the sections where the growing season is short 
and the moisture supply is fairly abundant either from rainfall or irrigation. 
Han River (C. I. No. 206) also produced comparatively high yields. White 
Smyrna (C. I. No. 910), which was the highest yielding variety at this station 
under dry-land conditions, was the lowest of the varieties grown under irrigation 
Ln the years 1914 to 1921, inclusive. Hannchen and White Smyrna usually are
