" It would appear from these riisiilts that rather more tlian 160 pouiuls 

 of either sulphate or muriate of potash would be beneticial to the) 

 tobacco crop." 



The author's couclusions from the j-ear's experience are : 



(1) That commercial fertilizers materially increase the yield and improve the 

 quality of Barley tobacco. 



(2) That the increase is obtained whether potash, phosphoric acid or uitrogen are 

 used separately or in various combinations. 



(3) That potash aud nitrogen in combination seem to be required to produce the 

 best results. 



(4) That there is a handsome profit by using fertilizers in the best combinations. 



(5) That the effect was [nearly] the same whether potash was used in the form of 

 muriate or sulphate. 



(6) That nitrogen in the form of nitrate of soda seemed to produce the best results 

 as to quality.

Commercial fertilizers, M. A. Scovell, M. S. — This coutaius 

 popular accounts of common fertilizing materials, exj)lanations of fer- 

 tilizer analyses aud valuations, brief directions regarding the applica- 

 tion of fertilizers, and the tabulated results of analyses of ten brands 

 of raw-bone manures, and fifty-four brands of complete fertilizers, su- 

 perphosphates, etc.

Experiments with wheat, M. A. Scovell, M. S., and C. L. 

 Curtis (pp. 3-16). — These were a continuation of the experiments 

 reported in Bulletin Xo. 21 of this station (See Experiment Station 

 Record, Vol. I, p. 218). They included tests of varieties, methods of 

 seeding and fertilizers, and were conducted on the station farm, which 

 is in the Blue-Grass region, and has a light clay subsoil, retentive, and 

 without proper drainage. The farm is, therefore, not especially adapted 

 to wheat. 



Test of varieties (pp. 3-7). — A tabular record of tests of twenty-nine 

 varieties is given, including data for the season of growth, the yields per 

 acre of grain and straw in 1890, and the yields of grain per acre in 18S9 

 and 1890. The plats used comprised one fiftieth of an acre each. "A se- 

 vere freeze on March 6 seriously damaged the crop. Some of the varie- 

 ties, as Extra Early Oakley, were almost entirely destroyed. * * * 

 From the two years' results it would appear that German Emperor aud 

 Hunter's White are especially worthy of trial by farmers, while many 

 others are almost equally as good." 



Methods of seeding ([)p. 7, 8). — A brief tabular record for the second of 

 a series of experiments with different methods of seeding. The seasoa 

 was of such a character as to render the experiment inconclusive.
