44 EXPERIMENT STATION RECORD. 



Method of i^rejjaring Und (pp. 116-118).— Fall plowing, spring plow- 

 ing, and disking the land were compared; also cultivating the seed in 

 vs. drilling. "The spring-])lowed laud on wliicli the seed was drilled 

 in gave the best results in nearly every instance." 



Time of seeding (pp. 118, 119).— This experiment occupied 45 plats. 

 Oats were sown March 1, 8, 15, 22, 29, April 5, 12, and 26. The yield 

 decreased as the date of sowing became later. 



EoUcater treatment for smut (pp. 119, 120).— This treatment has also 

 been described in Bulietiu 29 of the station (E. S. R., 3, p. 789). "The 

 average for the 5 years shows a gain of 2 bu. to the acre in favor of 

 the treatment." 



Light, medium, and heavy seed (pp. 120, 121).— The averages for the 6 

 years give a yield of 28.48 bu. for light seed, 29.85 bu. for medium, and 

 30.76 for heavy seed. 



Methods of seeding (pp. 121, 122).— As the average of 5 years' trials 

 broadcasting yielded 26.18 bu. per acre, seeding with the hoe drill 25.71, 

 seeding with the shoe drill with press wheels 30.31, and seeding with 

 the shoe drill without press wheels 28.72 bu. 



Amounts of seed (pp. 122, 123).— In 1894 and 1895, U to 2^ bu. gave 

 the largest yields; in the 3 years previous, 4 bu. gave the largest 

 returns. 



Tivie of harvesting (p. 123). — In 1894 oats cut in the dough yielded 

 17.85 bu., cut in the hard dough 21.08, and cut when ripe 26.37 bu. 



Varieties (pp. 123, 124). — The following have given the largest aver- 

 age yields for 5 years: Northwestern White, Belgian, Pedigree Eed 

 Eust Proof, Board of Trade, Golden Sheaf, and Brown Winter. 



The assimilation of fertilizing materials, and the fertilizer 

 requirements of rye, Eemy {Jour. Landw., 4-i {1896), No. 1, j;j>. 31- 

 103). — After a discussion of the relation between the fertilizing mate- 

 rials taken up by the plants and the increase in plant substance, the 

 author reviews the work of previous investigators in this line. 



Experiments were conducted in 1891 and 1893 on 56 i)lats of 50 

 square meters each. Nitrate of soda 3 kg., carbonate of potash 3 kg., 

 and superphosphate 3 kg. per plat were applied singly, two by two, 

 and all tliree together. 



Full tabulated data are given and discussed under the following 

 heads: Effect of manuring (1) on the moriihological development of rye, 

 (2) on the yield; absolute quantities of fertilizing materials; assimila- 

 tion of fertilizing materials, and the manurial needs of rye. 



On the basis of the exi^erimeutal data the author concludes that 

 certain laws obtain in the relation between the assimilation of fertiliz- 

 ing materials and the production of dry substance in rye; that both 

 processes, as well as the relations between them, are little aftected by 

 the manuring, and that the weather has more influence on these proc- 

 esses than the manuring. 



It was found that a rapid assimilation of nitrogen took i»lace in the
