IMPEOVED STRAINS OF GKASSES 78 



already in 1910 an invitation to enter samples for a second series 

 was issued, and samples of cocksfoot, timothy, Italian ryegrass, 

 and red clover were entered. The samples were sown in 1911 

 and 1912, under cover of a corn crop, to be harvested in 1912-13 

 and 1913-14. They were sown on five Experimental Stations 

 on 6 to 12 parallel plots of from 12 to 24 square yards, and 

 trade samples and samples of the strains from Tystofte were 

 grown for comparison. The results were published in 1913 

 and 1915 in a report by E. Lindhard. 1 



In both series the Olsgaard strain gave the greatest yield of 

 hay of all the samples of cocksfoot tested. It belongs to 

 Kr. Easmussen, of Hojgaard, and is grown, as are all the best 

 strains of the different kinds of grasses, by most of the seed 

 merchants and associations of seed growers. Of Italian rye- 

 grass a Tystofte strain, No. 152, was by far the best in both 

 series. When seed of this strain was offered for sale first time 

 in 1912 the stock of seed, 12 cwts., was bought in 1 cwt. 

 parcels in the course of a few days at a price of about 22 10s. 

 per cwt. 2 by seed merchants and seed growers' associations, 

 which proves that these felt confident that Danish farmers 

 would be willing to pay a good price for seed of a specially good 

 strain, as they had done with regard to strains of root seed. 

 And in this confidence they were not mistaken, as already 

 mentioned. Of meadow fescue the best strain was found to 

 be one belonging to F. D. B., and known as Lyngby No. 9, 

 having been improved by cultivation at the Co-operative 

 Societies' farm at Lyngby. Tystofte No. 70 and 71 were the 

 best early red clovers in 1909-12, but in the second series 

 another strain, Vormark, was the best, with Tystofte 70 as 

 No. 2. Of late red clover, a Tjsereby strain, was first in the first 

 series, but came second in the second series, while Hersnap 

 took the lead. Of white clover the Mors0 strain was the 

 best. 



The result of these Comparative Cultivations of the plants 

 of rotation grass fields, on the same principle as the Comparative 

 Cultivations of different strains of the different kinds of roots,
