SOURCES OF RUSSIAN CLOVER SEED EXCEPT NO. 16. 



Four Russian varieties were included in that part of the experiment 

 under discussion, but, as may be seen by reference to Table I, not all of 

 these were included in the series tested in each of the six States. 

 Russian seed No. 15 was purchased in the open market under the 

 trade name " Russian Rio." This seed was grown in the Province of 

 Kief, in southwestern Russia, and, in common with all other strains 

 used in this test, is of the crop of 1903. Seed from this same region, 

 but of a previous crop, made a particularly good showing in Wisconsin 

 in 1903, producing a plant that appeared to possess several excellent 

 qualities not common to our own domestic strains. On this account 

 a special effort was made to include a sample of this seed in these 

 comparative experiments. Its productiveness and quality in 1903 

 were fully equaled in 1905, and but for the superior performance of 

 No. 16, with which it has many points in common, it might well be 

 recommended for use in the Northwest and elsewhere to take the 

 place of our domestic strains. It has in all cases proved to be, like 

 No. 17, intermediate in lateness of maturity, being later than No. 18 



a The minus sign indicates that the strain opposite whicli it occurs was omitted fi'om 

 the series grown in the State specified.
