638 EXPERIMENT STATION RECORD. 



II. Comparative tests of sugar-beet varieties, J. E. W. Tracy (pp. 71-78). — 

 This report is supplementary to Circular 37 of the Bureau of Plant Industry 

 of this Department, previously noted (E. S. R., 21, p. 733). Tables present the 

 results of variety tests and indicate that Morrison has stood first in yield of 

 roots and of sugar during the entire 6-year period. 



III. The curly-top of beets, H. B. Shaw (pp. 79-8 ,. — This article is an ab- 

 stract of Bulletin 181 of the Bureau of Plnnt Industry of this Department, pre- 

 viously noted (E. S. R., 23, p. 557). 



Sugar cane in Porto Rico, D. W. May {Porto Rico Sta. Bui. 9, Spandsh Ed., 

 pp. 1-JiJt, pis. 3). — A Spanish edition of the bulletin previously noted (E. S. R., 

 23, p. 237). 



Report on turnip manuring experiments, 1909, R. B. Greig {Aberdeen and 

 No. of Scot. Col. Agr. Leaflet 11, pp. 6). — When used with 5f cwt. of super- 

 phosphate and li cwt. of potash manure salts, sulphate of ammonia, calcium 

 cyanamid, nitrate of lime, and nitrate of soda are considered of practically equal 

 value in the production of turnips. In a test showing the effects of omitting in 

 turn potash, phosphoric acid, and nitrogen from a complete fertilizer the check 

 plat averaged during 6 years 8 tons 12 cwt. of turnips per acre. With the com- 

 plete mixture, ? cwt. sulphate of ammonia, SJ cwt. superphosphate, and IJ cwt. 

 of potash salts, there was an average yield of 19 tons 6 cwt. per acre. The 

 omission of potash apparently decreased the yield by 3 tons, the omission of the 

 phosphate by 8 tons 8 cwt., and the omission of the nitrogen by 2 tons 5 cwt. 

 Ground Belgian phosphate produced an average yield at 9 centers of 2 tons 8 

 cwt. less than superphosphate, practically the same as ground Algerian phos- 

 phate, and more than 1 ton more than ground Florida phosphate when applied 

 with I cwt. sulphate of ammonia, li cwt. potash salts and dung, but when ap- 

 plied without dung it yielded 2 tons 6 cwt. less than superphosphate, 1 ton 7 

 cwt. less than Algerian phosphate, and 1 ton 10 cwt. more than Florida phos- 

 phate. Six cwt. of basic slag yielded 1 ton 12 cwt. more turnips at 1 center and 

 17 cwt. more at another than 6 cwt. of superphosphate when both were applied 

 with 1 cwt. each of sulphate of ammonia and potash salts. 



A dark brown or black powdery by-product of the distilling industry known 

 as Rothes fertilizer contained 5.11 per cent nitrogen, 5.3 per cent phosphoric 

 acid, and 4.17 per cent potash. An application of 6 cwt. of this fertilizer was 

 followed by a yield of 10 tons 1 cwt. of turnips as compared with 4 tons 17 cwt. 

 on the check plat and 8 tons 4 cwt. after an application of artificial manures 

 containing the same amount of nitrogen, phosphoric acid, and potash. 



Wheat in India; its production, varieties, and improvement, A. and G. L. C. 

 Howard {Calcutta: Govt., 1909, pp. IX+2S8, pis. 7, figs. 4, maps 7). — This vol- 

 ume contains general information on the distribution, irrigation, cultivation, 

 harvesting, and marketing of wheat in India, as well as on the soils devoted to 

 it, rotations used, and the commercial phases of wheat production following 

 cultivation. The results of manurial, irrigation, and cultivation experiments 

 and of tests of implements and machines at the Cawnpore, Poona, and other 

 experimental farms of India ai'e presented. Insect pests and diseases are dis- 

 cussed and an account given of the improvement of Indian wheat by the intro- 

 duction of new varieties, seed selection, and plant breeding, with the results 

 of recent investigations in these lines. The wheats of different provinces are 

 classified, described, and illustrated.
