532 EXPERIMENT STATION RECORD. 



Of varieties and strains tested at Tullman tlie Flint variety Gehu, North Da- 

 kota White Flint, Rhode Island White Flint, and a Yellow Flint secured from 

 Leland, Idaho, and the Dent varieties, Yellow Dent secured from Oakesdale, 

 Wash., Yellow Dent from Pullman, Wash., Northwestern Dent, North Dakota 

 Golden Dent, Dent secured from Myers Falls, Yellow Dent secured from Pull- 

 man, Wash., Minnesota King, and White Dent secured from Pullman, matured 

 in about the order named. Minnesota No. 13, Bloody Butcher, and White Cap 

 Yellow Dent did not mature at the station, but are regarded as promising 

 varieties for the warmer and longer seasons of Walla Walla and similar locali- 

 ties. 



Thayer Dent and Windus Dent were selected for improvement and distribu- 

 tion. They are briefly discussed as are also Minnesota King and certain other 

 varieties tested. Cooperative trials of the Thayer and Windus varieties in 

 1910 indicate that a majority of the farmers reporting results from that part 

 of the wheat region where the rainfall exceeds 15 in. were successful with these 

 varieties, but that in the very dry belt a majority reported failures. 



Some possibilities of the cowpea in Macon County, Alabama, G. W. Carver 

 (Alabama Tuskegcc Sta. Bui. 19, pp. 5-23, figs. 5). — Directions for the produc- 

 tion and harvesting of cowpeas and a discussion of their value as food for man 

 and animals are followed by directions for preparing numerous dishes from 

 the cowpea previously noted (E. S. R., 20, p. 169), and notes as to diseases and 

 insect pests. 



Groundnuts in the Bombay Deccan, G. H. Kelkar (Dept. Agr. Bombay BuL 

 Jjl, 1911, pp. 17). — Tables report the area devoted to peanut growing in the Bom- 

 bay Presidency, the average rainfall of the places where this crop is grown, and 

 the exports, covering the past 14 years in each case. The author assigns as 

 causes for the decline in acreage (1) the tikka disease due to Septoglcum ara- 

 chidis, (2) unfavorable seasons, (3) the degeneration of seed due to improper 

 cultural methods, (4) lack of proper rotation, and (5) failure to replenish the 

 soil by the addition of manure. 



An itemized statement of the cost of production and the returns per acre 

 of peanuts indicates a profit of 37* per cent. In tests, fungicides gave negative 

 results so far as the tikka disease was concerned. Newly imported varieties 

 were attacked by the disease, but some promised to escape serious damage 

 because of their early ripening period. 



In a test of 5 varieties. Big Japanese and Selected Virginia produced the 

 highest yields of 3,171 and 2,966 lbs. per acre, respectively. A table states the 

 oil content, number of kernels per pod, and percentage of kernels to nuts of the 

 original seed and the farm-grown crop of each of the 5 varieties. 



In a rate of planting test the larger varieties were planted 12 in. apart each 

 way and 12 by 9 in., while the smaller Spanish and Japanese varieties were 

 planted 9 by 6 and 6 by 4 in. apart. Closer plantings produced the higher yields 

 in case of every variety except Tata. The Spanish and small Japanese varieties 

 stood highest in oil percentage and percentage of kernels. A table states the 

 weight per acre of (1) roots, stems, and leaves; (2) shells of seeds; (3) kernels 

 produced by each of the 6 varieties as well as the amount of nitrogen, phos- 

 phoric acid, and potash per acre produced by each of these 3 divisions of the 

 plant, and the amount of oil per acre produced by the kernels. 



Variety tests of oats, F. D. Gardner and J. A. Runk (Pennsylvania Sta. 

 Bui. lOS, pp. 3-77/).— Yields in 1906, 1907, and 1908, previously noted (E. S. R., 

 23, p. 536), are reported, and also yields in 1909 and 1910. 



In 1909 Japan oats yielded 68.4 bu. on its best plat as compared with cor- 

 rected yields of 63.6 and 63 bu. respectively from Kherson and Joauette. In 

 1910 the highest corrected yield of grain was secured from the variety 453-06.
