Effect of fertilizers on the proportion of grain to straw and 

 stover, H. J. Waters and E. H. Hess {VetmsylvanUi Sta. Rpt. 1895, 

 pp. 220-:^2:-!). — A table is given showing the latio of grain to stover 

 and to straw in crops of corn, oats, and wheat grown in rotation for 

 12 years (1883-'94) with diiiferent combinations and amounts of fertil- 

 izers. The most important of the authors' conclusions are as follows: 



"Tlie largest amount of stover (stalks without ears) in proportion to the ears pro- 

 duced, was derived troni the plats on which complete commercial fertilizer was 

 used. . . . Less excess of stover over grain is returned 1)> the barnyard manure 

 plats than from those receiving a complete commercial fertilizer, the difference 

 amounting to about 19 per cent. 



"In the case of oats the reverse is true. The largest relative yield of straw is 

 from the barnyard-manure plats, which show aliout 10 per cent more in proportion 

 to the grain than do the complete chemical manures. 



"Sulphate of ammonia shows a heavier yield of straw than does either nitrate of 

 8oda or dried blood. 



"Averaging the yields I'rom all sources of nitrogen, excepting iu the yard manure, 

 a slight increase in the straw yield is shown as the amount of nitrogen applied 

 increases. 



"With wheat the largest relative yield of straw is obtained from the plats receiv- 

 ing the complete commercial fertilizers. The proportionate yield of straw increases 

 as the amount of nitrogen used increases." 



General fertilizer experiments, H. J. Waters and E. H. Hess 



{Pennsylvania Sta. Epf. L'^O'j, pp. 211-219). — This is a continuation of 

 work upon the 4-year rotation of corn, oats, wheat, and grass. 



A summary of 3 complete rotations was given in tlie Annual Report 

 of the station for 1894 (E. S, R., 7, p. 943). The experiment was con- 

 tinued in 1895 according to the original plan, and tables are given show- 

 ing the yield per acre of the different plats and the effect of different 

 combinations and different amounts of fertilizers. Notes are given 

 upon the crops but no conclusions are drawn. 



Sunflov^er heads and blackeye peas as silage crops, J. M. Bart- 

 lett {Maine Sta. Kpt. 1895^ pp. 21-23). — These crops were grown and 

 ensiled in the proportions of 0.25 acre of sunflowers and 0.5 acre of 

 peas to 1 acre of corn. The peas were affected with mildew so the 

 yield was rather light. The sunflowers were grown upon laud pre- 

 pared as for corn, the seed being planted 1 ft. apart, in drills 3.5 ft. 

 apart. The expense of raising the crop is about the same as for corn. 



The following table shows the yield per acre and percentage com- 

 position of the air dry material iu the sunflower heads and peas:
