CEREAL EXPERIMENTS IN MARYLAND AND VIRGINIA.

two hybrids, Nesbian and Omar, are spring varieties that have 

 been grown from fall seeding. In 1911 several of these 2-rowed 

 spring barleys outyielded the best 6-rowed winter barleys, but the 

 following year more than half of them were completely winterkilled 

 during the severe weather in January. It is doubtful whether any 

 of the 2-rowed spring varieties can be grown successfully from fall 

 seeding during a series of years. 



The yields obtained from the naked barleys also are unsatisfac- 

 tory. The yields of these varieties shown in Table XII are calcu- 

 lated at 60 pounds to the bushel, the standard weight for this group. 



The average dates of heading and of maturity, height, yield of 

 gram and of straw, and weight per bushel of the four leading varie- 

 ties of barley at College Park for the seven years from 1908 to 1914 

 are shown in Table XIII. The same data for 16 of the more impor- 

 tant varieties and strains grown at Arlington Farm for periods rang- 

 ing from two to six years are also given.

Table XIII shows that the more important varieties have ripened 

 about June 10 at College Park and from June 3 to 6 at Arlington Farm. 

 The earliest varieties at Arlington Farm are the three hybrids, Arling-
