FIELD CROPS. 739 



No. 1561) tuifl the Shinriki (G. I. No. 1642) varieties yielded 113.7 and 137.2 bu. 

 per acre respectivelj'. 



It was found .that in the Sacramento Valley the rices under test requii'ed a 

 longer time to mature and produced smaller plants than when grown on the 

 plains of the (Uilf coast, but that they exhibited a greater capacity for tillering 

 with resultant larger yields. The Honduras and Shinriki varieties (G. I. Nos. 

 1643 and 1642), the leading commercial rices of the United States, exceeded in 

 this test the maximum yields produced on experimental plats in Louisiana and 

 Texas. Of the two, the Shinriki is considered better adapted to the Sacra- 

 mento Valley. It is pointed out that the Wataribune, the Oiran, and the Shin- 

 riki varieties produced good crops but that earlier maturing varieties of good 

 qualitj', though producing less per acre, may be more remunerative for this 

 locality. Suggestions as to the methods of culture are given and the statement 

 is made that the results of the 2 years' work indicate the iwssibility of rice 

 vulture in the Sacramento Valley. 



Rice crop of the United States, 1712-1911, G. K. Holmes (U. S. Deft. 

 Agr., Bur. Staiis. Circ. 34, PP. H)- — Tables are given showing in so far as data 

 were obtainable the production, value, domestic exports, imports, and con- 

 sumption of rice for the United States for the years 1712-1911, inclusive. 



Tobacco crop of the United States, 1613-1911, G. K. Holmes (U. S. Depf. 

 Agr., Bur. Statis. Circ. 33, pp. 12). — Data regarding the production, value, 

 domestic exports, net imports, and consumption of tobacco in the United States 

 from 1612-1911, inclusive, are given in tables. 



Tobacco report, July 1, 1912, J. I'. Killekrew ( {/. S. Dept. Agr.. Bur. 

 Statis. Circ. 3S, pp. 7). — The acreage of tobacco in the United States July 1, 

 1912, by States and districts is reported in rallies and the condition of the crop 

 at this date is described. The 1912 area of cigar-leaf tobacco is given at 

 172.400 acres against a final estimate of 177.400 acres in 1911, and the acreage 

 of the chewing, smoking, snuff, and export type is reported at 1.012,300 acres 

 as compared with a final estimate of 819.r)(X) acres in 1911. 



Growing' winter wheat in Iowa, L. C. Burnett {Iowa Sta. Bui. 133. pp. 

 259-273, figs. 11). — This bulletin reviews the history of winter wheat in Iowa, 

 presents statistics showing the relative production of spring and winter wheat 

 for the State, and reports the results of experiments carried on by the station. 

 Notes are given on cultural methods and on crop rotations including winter 

 wheat. 



The average yields of 4 winter wheat and 4 spring wheat varieties at the 

 station for the 5 years 1906-1910. inclusive, were 33.8 and 24.2 bu. per acre, 

 resi^ectively. Experiments with 10 varieties of winter wheat carried on from 

 1906-1910 showed that the Russian types Malakoff. Imported Turkestan, Min- 

 nesota No. 529, and Turkey Red gave uniformly good results and produced on 

 an average for this 5-year period 36.9, 36. 35.5, and 34.3 bu. per acre, respec- 

 tively. 



A 4-year comparison of drilling and broadcasting winter wheat resulted in 

 an average yield of 29.1 bu. per acre on the drilled and of 24.9 bu. on the 

 broadcasted plats. It is stated that the best results at the station were secured 

 from placing the seed in the top of the moist earth below the dust mulch, or 

 about li to 2 in. below the surface. The yields so far obtained have favored 

 sowing early in September. In 1912, the station obtained a good stand and 

 also broke the crust by drilling clovei in the standing wheat about April 20. 



On the vitality of farm seeds, W. Carbuthers {Jour. Roy. Agr. Soc. England, 

 12 (1911), pp. 168-183, figs. 5). — The author describes briefly a machine similar 

 to, or identical with, the '• Preparator " previously described by Hume and
