FIELD CROPS, Y33 



stance of an earlier contribution by tlie author In collaboration with A. B. 

 Bruce and F. J. M. Strattou, previously noted (E. S. R., 24, p. 633). A table 

 of odds has been added and its use is explained. 



Methods of farming- in older settled districts (Ann. Rpt. Dept. Agr. Sas- 

 katcheican, 6 (1910), pp. S5-90). — The author summarizes the answers received 

 from the older settled districts of Saskatchewan to inquiries sent out to deter- 

 mine the average size of farms and changes in agriculture, resulting princi- 

 pally from the fact that the soil has been under cultivation for a considerable 

 period. 



Of those replying, 22 per cent farm a section, 23 per cent three-fourths of 

 a section, and 33 per cent half a section of land. Seventy per cent state that 

 they secure as good wheat yields as when they began farming in this prov- 

 ince. Twelve per cent report increased yields, while 15 per cent report de- 

 creased yields which some attribute to variable seasons. Practically all state 

 that better cultivation is now necessary in order to maintain the high yields. 

 Ninety per cent state that the land is now easier to plow, but 40 per cent 

 complain of the soil " blowing." Packing is reported to have obviated this 

 difficulty in a number of cases. Weeds have caused changes in farming 

 methods in 58 per cent of the cases, but the use of crop rotation is still in the 

 experimental stage and no definite percentage of farmers reporting it is stated. 

 One third are experimenting in the growing of grasses and alfalfa, while 67 

 per cent have done nothing in the way of growing leguminous crops. 



Variety tests during- 1910, O. Leiimermann and P. Liebau (Landic. JaJvb., 

 ffl (1911), Xo. S-Jf, pp. 3S9--'ilo). — These pages present in tabular form the 

 results of tests of varieties of winter i-ye, winter wheat, winter barley, spring 

 wheat, oats, sugar and other beets, red clover, alfalfa, and corn. In connec- 

 tion with most of the crops the date and rate of sowing, date of harvesting, 

 the method of fertilization, and the crop which occupied the land during the 

 preceding year are stated. 



These tests were conducted on the experiment fields of the Royal Agricul- 

 tural High School at Dahlem. Eaiiier variety tests by the same authors have 

 already been noted (E. S. R.. 24, pp. 731, 732). 



[Experiments with fi.eld crops], F. Watts et al. (Rpts. Bot. Sta. [etc.] 

 Antigua, 1910-11, pp. 8-31). — Meteorological data are followed by notes on 

 the cotton industry and numei'ous lines of experimental work taken up by the 

 station during 1910-11. Tables state in full results obtained in tests of 

 cassava varieties during 4 and 6 year periods, and of sweet potato, yam, cot- 

 ton, eddoe, tania, and broom corn varieties during briefer periods. Notes are 

 also given on an experiment for the control of the root disease of corn. 



[Corn, sugar cane, rice, and cotton experiments], F. A. Stockdale (Rpt. 

 Bot. Ganl. Brit. Guiana, 1910-11, pp. ll-l'i). — These pages give brief progress 

 reports of work with corn and sugar cane and of hybridization experiments 

 with rice and cotton. 



Winter cereal report for 1910: State farm, Rome, Bungeworgorai (Queens- 

 land Agr. Jour., 26 (1911), Nos. 2, pp. 5S-62; 3, pp. 11 1-llS).— This article 

 reports the results of variety and fertilizer tests, hybridization work, and 

 miscellaneous sowings of cereals. 



Infl.uence of low temperature and of the snow covering on the winter- 

 ing- of cereals, A. Stebut (ViestnJk Russ. Selsk. Ehoz., 1910, Nos. 38, 39; 

 abs. in Zhnr. Opytn. Agron. (Russ. Jour. Expt. Landw.), 12 (1911), No. 1, 

 pp. 13.'i, 135). — After a comparative study of the yields and meteorological 

 data for a series of years, the author concludes that cold winters are followed 

 by wheat yields somewhat below the average and rye yields somewhat higher
