240 EXPERIMENT STATION RECORD. [Vol.38 



Tests with Miracle wheat in 1912 sown at 1- and 2-bu. rates gave yields of 

 25.5 and 30.S l)u. per acre, respectively. In 1914 other samples of the same 

 variety, deslKiinted as Marvelous, were sown at 1-, 3-, 6-, and S-pk. rates and 

 yielded 23.8, 33.1, 30.5, and 34.8 bn. per acre, respectively. The variety faile<J 

 to tiller more than the majority of the other varieties tested. 



Marquis and Minnesota 1G9 sprinR wheats were sown in 1915 and 1910 and 

 gave average yields of 13.1 and 13.2 bu. per acre, respectively. In 1? 6, 32 

 commercial varieties of oats were grown with the wheats, giving an average 

 yield of 70.1 bu. per acre. Winter wheat grown these two years averaged 

 32.G bu. per acre for 30 conmiercial varieties. The spring wheat is said to 

 have been shriveled and of poor quality and is deemed unsuited for Pennsyl- 

 vania conditions. 



Wheat culture in Pennsylvania is outlined and the principal insect and 

 diseas(> enemies of the crop briefly discussed. 



Wheat culture, T. B. Hutcheson and T. K. Wolfe {Virginia Sta. Bui. 216 

 {1911), pp. 15, figs. 3). — Approved methods of wheat production are outlined 

 and limited tests noted with dates, rates, and methods of seeding and with 

 fertilizers. 



Fulcaster, Dietz Amber, and Stoner bearded wheats and Fultz, Leap Prolific, 

 and Harvest King smooth varieties are deemed best for Virginia conditions. 



Seed treatments for the loose and stinking smuts of wheat are noted. 



Wheat growing in the Southeastern States, G. E. Leighty {U. 8. Dept. Agr., 

 Farmers' Bui. SS5 {1917), pp. Hi). — An increased acreage of wheat is recom- 

 mended for Tennessee, North Carolina, Mississippi, Alabama, Georgia, and 

 South Carolina as a means of crop diversification and of providing home-grown 

 bread. The sandy loam, silt loam, loam, and many clay soils when drained, 

 well tilled, and fertilized are deemed suitable for wheat production, while the 

 lighter, sandy soils, especially in the Coastal Plain, are regarded as better 

 adaptetl for rye. The soft, red, winter wheats are thought best from all 

 standpoints. Crop pests (insects, diseases, and weeds) are briefly note<l and 

 approved methods of control outlined. The value of wheat as a nurse crop, 

 for hay, and for fall and winter pasture is also indicated. 



[Cultui'al experiments with wheat growing], W. J. Spafford {Jour. Dept. 

 Agr. So. Aiist., 20 {1016), No. 4, pp. 278-280; 20 {1017), No. 7, pp. 550, 551).— 

 Experiments conducted by T. Griflln since 1908 with different cultural treat- 

 ments of wheat grown under dry-farm conditions are briefly reported. 



The results for the period of 1908-1915 indicated that op subpacking land 

 before seeding there was no increase over land not subpacked, and that with 

 subpacking immediately after plowing the average increase in yield was only 

 1 bu., not deemed sufficient to encourage the practice. Tests in 1915-16 included 

 a comparison of rolling and subpacking on G-in. plowing and on 3-ln. plowing, 

 and of land cultivated at plowing time and then treated as ordinary plowed 

 fallow. The results for 1916 indicated that there was practically no difference 

 in yield between subpacking and rolling, the yields being approximately 20.6 and 

 19.8 bu., respectively, for the 6-in. plowing, and 18.06 and 18.7 bu., respectively, 

 for the 3-ln. plowing. Land cultivated at plowing time and treated as fallow 

 gave a yield of 17.2 bu. 



The seeds of cultivated plants and their identification, L. Pkancois (Ann. 

 Sci. Agron., 4. scr., 4 {1915), No. 1-6, pp. 30-55; 5 {1916), No. 1-6, pp. 207-295, 

 figs. 121). — This is an extensive discussion of the functions of the seeds of cul- 

 tivated plants, together with tables and Illustrations for their identification.

 samples of farm seeds and 372 samples of vegetable seeds for the year 1915-16.
