FIELD CROPS. 233 



Time and rate of sowing oats, A. J. Hansen and N. Thyssen {Tid-sskr. 

 Lamibr. I'hintcavl, 15 {lUOS), .Vo. .'/, /jy>. SOi^-'i^G). — From the I'esults of experi- 

 ments conducted at four Danish experiment stations from 1S96 to 1903 it is 

 concluded that oats should be sown as early in April as weather conditions 

 will permit and not later than May 1. Danish oats gave most satisfactory 

 yields when sown at the rate of about 5 bu. per acre and gray oats at the 

 rate of about 4 bu. 



Manuring oats in the Western Province, A. K, Hards {Agr. Jour. Cape 

 Goud Hope, SJ, (HM)), Xo. //, pp. J,().')-',U, dijm. i).— Tabulated results of coo])- 

 erative fertilizer tests show that all applications except the use of 10 tons i^er 

 acre of kraal manure gave a profit this season. One hundred lbs. of nitrate 

 of soda applied with 200 lbs. of basic slag or superphosphate per acre gave a 

 good increase, but when either of these substances were used alone or in com- 

 bination with 40 lbs. of sulphate of potash the inci'ease in yield hardly paid 

 for the application. 



Manuring oats in the Longkloof, K. W. Thornton {Agr. Jour. Cape Good 

 Hope, .i.'f (t'JO'J), Xo. .'/, pp. .J/J- J/-', dgiii. I). — In these experiments 100 lbs. of 

 nitrate of soda per acre used alone ov with 40 lbs. of sulphate of potash re- 

 sulted in a loss. A profit was secured when it was applied with 200 lbs. of 

 basic slag, but when used with 200 lbs. of superphosphate no increase in yield 

 was obtained. 



Seasonal report of potatoes, 1908 {Ohio Sta. Circ. 90, pp. 7, charts 5). — 

 This circular embodies data based on notes taken at the station and on reports 

 received from several hundretl farmers representing every county in the State. 

 At the station this season a high yielding strain of Carman No. 3, selected for 

 5 years, gave an increase in yield of about 41 per cent as compared with un- 

 selected stock. The results of other selection work indicates that if the highest 

 yielding hills are selected without much regard to blight better yields will be 

 secured than if blight resistance alone is considered. 



[Report of] potato growers' field meeting {OJiio Sta. Circ. 89, pp. 11-19, 

 pgs. 2). — This is the report of a special potato growers' field meeting held in 

 October, 1908, under the auspices of the Ohio State Horticultural Society, and 

 includes reports of papers on Varieties of Potatoes by D. Egbert, and Potato 

 Seed Selection and Improvement by F. H. Ballon. 



Rape culture, T. Remy {Fiihling's Landw. Ztg., 58 {1909), Xo. 3, pp. 81-92).— 

 The results of variety tests of rape show that Dwarf ra])e led in yield of grain 

 and Holland rape in yield of straw. Holstein and Canadian rape also gave 

 good results. There was little difference in the oil content of the seed. 



In culture tests the best results with the crop were secured when it was 

 grown on black fallow. A table reporting the study of plant-food requirements 

 of various crops in different months of the growing season shows tliat rape uses 

 large quantities of nitrogen, phosphoric acid, and potash in the fall from 

 Se])tomber to November. The only crop resembling rape in this respect was 

 I'uta-baga. 



The sugar content as a transmissible character in the sugar beet, K. 

 Andkli'k, V. Bartos, and J. Urban {ZtscJir. Ziickcrindus. Boh men, 33 {1909), 

 Xo. 6, pp. 3.'i5-357, flgn. 7). — The investigations described show that 100 indi- 

 viduals, each grown from three isolated mother beets high in sugar and belong- 

 ing to strains of high transmission, had an average sugar content only 0.15 to 

 0.35 per cent smaller than that of their mothers, which ranged from 18.9 to 

 19 per cent. The largest number of the progeny carried from 18.5 to 19 per 

 cent of sugar. In the case of 100 individuals from three rich mother beets 

 fertilized by beets also rich in sugar, the average sugar content was 0.8 per 

 cent lower with one mother beet and 0.00 per cent lower in another, while in
