438 EXPERIMENT STATION RECORD. [Vol.37 



Cereal experiments, A. C. Tonnelieb {Experiencias sobre Cereales. Buenos 

 Aires: Min. Agr., 1914^ PP- 239, figs. 38). — Field tests with wlieat. barley, rye, 

 and oats from 1910 to 1913, inclusive, are reported. Including general notes on va- 

 riety tests with each cereal for 1910 and 1911 (pp. 5-75) ; notes on variety tests 

 for 1911 and 1912 (pp. 79-133) ; notes on fertilizer and cultural experimeots 

 with wheat and barley for 1911 and 1912 (pp. 137-169) ; and notes on variety 

 tests with wheat, barley, and rye for 1912 and 1913 (pp. 173 to 239). 



Seed grain inspection and crop reports, 1915—16, J. J. Garland (Ann. Rpt. 

 Wis. Agr. Expt. Assoc, 14 {1916). pp. 11-16). — The reports of members of the 

 Wisconsin Agricultural Experiment Association on the yields of pedigree grains 

 grown in 1915 show that pedigreed barley yielded 5.5 bu. per acre in excess of 

 the United States average, pedigreed oats No. 1 9.3 bu. and pedigreed winter 

 rye 4.4 bu. over other varieties, and pure-bred corn (Wis. No. 7) 23 bu.. select 

 winter wheat 10.4 bu., and spring wheat 10 bu. over the United States averages. 

 Data are also presented from experiments conducted by members of the associ- 

 ation on rates of seeding, drilling v. broadcasting, and spring v. fall plowing. 



Some effects of legumes on associated nonlegumes, M. W. Evans (Jour. 

 Amer. Soc. Agron., 8 (1916), No. 6, pp. S48-S57, pis. 2).— This is a further study 

 of some of the effects of legumes on nonlegimies growing in a mixture with 

 them. The experiments described were performed during 1912, 1913. 1914. and 

 1915 at tho timothy breeding station at New London, Ohio, which Is conducted 

 cooperatively by the U. S. Department of Agriculture and the Ohio Experiment 

 Station. The leguminous plant used was clover (Trifolium pratense and T. 

 repens), while timothy { Phlcuni pratense), redtop (Agrostis alba), and Ken- 

 tucky blue grass (Poa pratcnsis) were grown alone and in mixture with the 

 clover. 



The following table shows the percentage of increase in the protein content 

 and length of leaf in the grasses grown with clover over those grown alone:

Timothy plats receiving ammonium nitrate showed a somewhat greater In- 

 crease In percentage of protein in the grass over those plats where the grass 

 was grown in mixture with clover. 



Clippings from plats where grass was grown in mixture with clover showed 

 a larger proportion of green leaves and a correspondingly smaller projwrtion 

 of dry brown leaves than clippings from plats where grass was grown alone. 



Soy beans and cowpeas in Illinois, W. L. Bublison and O. M. Allyn (Illi- 

 nois Sta. Bui. 198 (1917), pp. 20).— The adaptability and production of soy 

 beans and cowpeas in central and southern Illinois are briefly discussed, with 

 a report of extensive variety tests at Urbana (Charapa.lgn Co.) and Fairfield 

 (Wayne Co.). 



The soy bean appears to be much better suited to Illinois conditions than the 

 cowpea, except on poor, unfertilized, sour soil in southern Illinois, where the 

 latter may be more hardy.
