36 EXPERIMENT STATION RECORD. 



A new forage crop, M. S. Beetoni (BoI. 8oc. Agr. Mexicana, 3'^ (1910), No. 

 33, pp. 650-652; Rev. Agron. y Bol. Estac. Agron. Puerto Bertotvi, 4 (1909), No. 

 1, pp. 7-11). — The author reports Andropogon sorghum perennis n. var., as a 

 new and valuable forage crop. He regards it as " a variety of Sorghum hale- 

 pense and Kafir." The chemical composition is stated. 



Composition of some forage beets (Betterave, 20 (1910), No. 511, p. 258). — 

 Analyses of 5 samples are given. 



Seed corn, C. P. Hartley ( U. 8, Dept. Agr., Farmers' Bui. 415, pp. 12, figs. 

 3). — A discussion of the value of good seed corn is followed by directions for 

 gathering, storing, testing, grading, and shelling corn for seed. 



Selecting and storing seed corn, C. P. Bull and L. H. Robbins (Univ. 

 Minn., Dept. Agr., Ext. Bui. 9, pp. 8, figs. 7). — Directions for selecting and stor- 

 ing seed corn are given. 



Cotton selection on the farm by the characters of the stalks, leaves, 

 and bolls, O. F. Cook (U. S. Dept. Agr., Bur. Plant Indus. Circ. 66, pp. 23).— 

 This circular discusses, in a popular way for the use of farmers, the essential 

 points to be kept in mind in cotton selection and breeding. Directions are 

 given for the use of progeny rows and the production of seed for sale. 



How much nitrogen does green manuring with lupines add to the soil? 

 H. VON Feilitzen (Monatsh. Latidio., 2 (1909), No. 3, p. 90; ahs. in Zenthl. Agr. 

 Chem., 38 (1909), No. 12, pp. 859, 860).— At Jonkoping, Sweden, blue and yellow 

 lupines were sown the middle of May and harvested September 2. The blue 

 lupine reached 125 cm. in height and fully developed its pods, but the yellow 

 was only 100 cm. high and only the lower pods were ripe when harvested. The 

 blue lupine excelled in earliuess and yield and was markedly higher in nitrogen 

 content in the portions above ground. 



The stubble and roots contained 9.9 per cent and 15.6 per cent of the total 

 dry weight, i-espectively, in the case of the blue and yellow lupines, and returned 

 to the soil 5 and 10.7 per cent, respectively, of the total weight in nitrogen. 

 These results are presented in columns parallel with those of Strebel (E. S. R., 

 4, p. 207) and Scholz-Lupitz for comparison. The fresh weight, dry substance, 

 organic substance, and nitrogen of the crop were determined. 



The potato as a truck crop, L. C. Corbett (U. 8. Dept. Agr., Farmers' Bui. 

 407, pp. 24, figs. 11). — This discusses the iwtato as a truck crop and the use of 

 northern grown, southern grown, second crop, and hold-over seed. The prepara- 

 tion of the soil and seed, planting, fertilization, cultivation, spraying, harvesting, 

 grading, and marketing are discussed. 



Change of seed and manurial tests, W. Angus (Jour. Dept. Agr. So. Aust., 

 14 (1910), No. 1, pp. 4~-49). — Newly introduced seed potatoes yielded from 

 I2 to 2 tons per acre more than local varieties. Tests of superphosphate, potash, 

 nitrate of soda, blood manure, and farmyard manure as fertilizers for i)Otatoes 

 are also reported. 



Rice culture, S. A. Knapp (C7. Sf. Dept. Agr., Farmers'' Bui. .)/?', pp. 30). — 

 This bulletin discusses red and commercial varieties of rice, the production and 

 importation of rice, rice soils, irrigation, seed-bed preparation, drainage, methods 

 of sowing, flooding, fertilizing, objectionable gi-asses, harvesting, thrashing, 

 milling, the effect of fashion in rice, rice as food, rice by-products, rice culti- 

 vation in southwestern Louisiana and southeastern Texas, and the prospects 

 for the extension of the rice industry. 



Wild rice seed for planting (Recreation, 32 (1910), No. 3, p. 149).— Wild 

 rice seed kept moist with a daily change of water during the winter, except 

 when a frozen mass of ice and seed filled the barrel, gave a 75 per cent germina- 

 tion test.
