Spring wheat for Illinois, W. L. Burlison and W. R. Staisk {IWnoii Sta. 

 Bui. 21k (1919). pp. 81.1-320). — Observations on growing spring wheat in the 

 northern pari of the Slate are briefly described. 



Early seeding is deemed essential for the best results, while somewhat higher 

 yields were obtained from the use of an 8 In. drill than with a 4 in. drill. Illinois 

 No. 1 was the highest yielding variety of spring wheat tested at Urbana (cen- 

 tral Illinois), producing an average of 29.3 bu. per acre for a -l year period, 

 while Marquis with an average of 34.8 bu. was first at De Kalb (northern Illi- 

 nois). In central Illinois hardy varieties of winter wheat have outyielded all 

 spring wheat varieties, while at De Kalb. due to partial winterkilling of fall- 

 sown wheat, Marquis has produced an average of 2.5 bu. per acre more than 

 Turkey Red, the hardiest winter wheat variety. At Urbana Turkey Red winter 

 wheat, Oderbrucker barley, and Sixty Day oats gave greater monetary returns 

 per acre than any spring wheat, while at De Kalb, Wisconsin Pedigree barley 

 gave better returns than any other spring-sown crop. 



Fourth annual report of the Montana grain inspection laboratory, A. At- 

 kinson and E. W. Jahnke (Montana Sta. Bui. 125 (1918), pp. 19). — This re- 

 ports work for the year ended September 30, 1917. Germination and purity 

 tests were made on COGS samples of seed sent in by farmers and seedsmen, and 

 on 2,082 official samples. 



Laboratory tests with 0G samples of frosted wheat resulted in an average 

 germination of 77 per cent, as compared with 93 per cent for unfrosted wheat. 

 Winter wheat showed 27 per cent germination one week after thrashing, 70 per 

 cent one month later, and 93 per cent two months later; spring wheat 31, 81, 

 and 94 per cent; oats 21, 57, and 83 per cent; and barley 43, 77, and 89 per 

 cent, respectively, for similar periods. 



Commercial agricultural seeds, 1918, C. D. Woods (Maine Sta. Off. Insp. 88 

 (1918), pp. 61-76). — Tables are given showing the results of the 1918 seed in- 

 spection, together with a list of the weed seeds found. 



Report of seed tests for 1918 (Bui. N. C. Dept. Agr., 39 (191S), Xo. 9, pp. 

 36). — This reports the results of purity and germination tests made by the 

 North Carolina State seed laboratory during the year ended July 15. 1918. A 

 total of 773 samples of agricultural seed and 3G3 samples of vegetable seed was 

 received from regularly appointed inspectors and from farmers. Tobacco seed 

 recleaned tor the tobacco farmers of the State amounted to 15G.149 cc. 



Disinfection of seeds with bromin, V. Artsixovsky and I. Stom (In Hibridl- 

 cultura i) Otros Trabajos tie las Estaciones. Madrid: Estac. Bntayo Scmillas, 

 1917, pp. 51-64, pl. 1, figs. If)- — The sterilization of peas, beans, corn, wheat, flax, 

 and pumpkin with 1 per cent solution of bromin is described, and the results are 

 reported of germination tests with peas, corn, wheat, and flax treated from 

 i to 4 hours and with beans and pumpkin seed treated from $ to 32 hours. 



The results are said to indicate that bromin is an effective sterilizing agent. 

 The viability of the seed was not seriously affected by the shorter periods of 

 treatment, except in the case of wheat, which was rendered practically useless 

 by treatments of only 30 minutes.
