MISCELLANEOUS DATA ON BARLEY. 



Some of the more important data on the varieties of barley in- 

 cluded in Table XVII are given in Table XVIII. The data were 

 obtained in the same manner as similar data upon the wheat and oat 

 varieties. Table XVIII shows the comparative behavior of the dif- 

 ferent varieties during the growing season, as well as the yield of 

 straw and grain, weight per bushel, height, and stand. 



Table XVIII. — Average miscellaneous data on" seven varieties of barley grown 

 at the Dickinson substation for periods of three to seven years {1901 to 1913). 



[Superior index figures indicate the number of years in whi-^h the data were obtained when this number is 

 less than the number of year; in which the variety was grown. For comparison, the yield of the 6-rowed 

 naked variety is given in bushels of 48 pounds. The actual yield in bushels of 60 pounds, the standard 

 weight, would be one-fifth less.]

Table XVIII shows that the barley varieties are all headed by 

 July 8 and ripe a month later, most of them requiring about 104 

 days from planting to maturity. The Gatami is the earliest varietj 7 , 

 requiring only 99 days from planting to maturity. The Hannchen 

 and Svanhals are the earliest 2-rowed varieties. The average height 

 of all varieties is about 27 inches. The Manchuria is the tallest 

 variety, with an average height of 32 inches, while the Hannchen is 

 the shortest, averaging only 25 inches. This is sufficient, however, to 

 permit binding with the ordinary harvesting machinery. Stand 

 notes for a number of years show no definite correlation to yield. 

 The yield of straw is correlated with the length of the growing 

 period, the later varieties producing the largest yield of straw. The 

 highest average weight per measured bushel is 49.6 pounds for the 

 Hannchen variety. 



MISCELLANEOUS CEREALS. 



A number of other cereal crops have been tested at Dickinson 

 during some of the years covered by this report. They are emmer, 

 winter rye, spring rye, flax, proso, and grain sorghum.
