436 EXPERIMENT STATION RECORD. [Vol. 43 



Maintenance of pastures and meadows, E. B. Stookey {Washington Sta., 

 West. Wash. &ta. Mo. BiiL, 8 {11)20), No. 3, pp. 36-39}.— The mowing, cultiva- 

 tion, resoeding, i'ertilization, and use of pastures and meadows is brielly dis- 

 cussed, and the annual results secured from 1913.-1919 on an experiment field 

 sown with grasses and clovers are noted. The field at the close of the period 

 was practically free from moss, and had very few weeds and a very good 

 stand of grasses and clovers, which made satisfactory growth. The plants 

 proving specially valuable and persistent were Italian rye grass, orchard 

 grass, tall oat grass, Kentucky blue grass, redtop, meadow fescue, white 

 clover, alsike clover, and red clover. 



Legume inoculation, A. F. Vass {Wyo^ning Sta. Circ. 15 {1920), pp. 4). — 

 A popular discussion of the purpose and value of inoculating soils for the 

 culture of leguminous crops, together with a description of methods of in- 

 oculation. 



Varieties of cotton, 1919, M. Nelson and E. A. Hodson {Arkansas Sta. 

 Bui. 166 {1920), pp. 3-8).— The yields secured in 1919 in cooperative tests with 

 standard varieties of cotton in different localities are tabulated. The tests 

 comprised three with 25 varieties, four with eight varieties, and one with dif- 

 ferent strains of a number of standard sorts. The results of only two of the 

 tests with 25 varieties are repoi'ted. In addition to yield the percentage, 

 length and value per acre of lint, and the approximate relative value of 

 staples in December, 1919, are also given. The highest yield in all tests, 2,664 

 lbs. of seed cotton, furnishing 900 lbs. of lint per acre, was recorded for Rublee, 

 with a length of lint of il in., and the higliest value of lint, $447.72 per 

 acre, for Foster, with a staple of IJ in. The results with these varieties were 

 obtained in the same test. 



Special cotton growing contest, C. D. Girola {Pub. Miis. Agr. [Soc. Rural 

 Argentina], No. 16 {1919), pp. 9, figs. Jf). — The conditions of a cotton growing 

 contest conducted in 1918-19 are given, and the results secured by 28 con- 

 testants in seven different provinces are reported.^ The varieties grown were 

 Chaco, Catamarca, Tanguis, Egyptian, Peruvian, Texas Wood, Simpkins, and 

 Sea Island. The yields secured ranged from about 210 lbs. to 2,230 lbs. of seed 

 cotton per aci"e. 



Flax culture in the Argentine Republic, C. D. Gikola {Put). Mus. Agr. 

 [Soc. Rural Argentina], No. 17 {1920), pp. 20, pi. 1, figs. 8). — A description is 

 given of flax culture for seed in Argentina including cultural practices, va- 

 rieties, weeds, diseases, and the uses of flax seed and its products, and the 

 results are reported of a contest in flax seed culture in 1918-19 instituted 

 by the Agricultural Museum of the Argentinian Agricultural Society. The 

 yields in the contest ranged from 12.66 to 31.83 bu. per acre. 



Prevention of sprouting and greening of potatoes by properly lighting, 

 ventilating, and cooling the storage rooms, G. Schneider {Dent. Landw. 

 Presse, 45 {1918), No. 51, pp. 315, 316, figs. 12).— The results of storage experi- 

 ments with potatoes, including tests of storing tubers in the dark, in daylight, 

 and under light of different colors such as red. blue, yellow, and green are 

 reported. 



The conclusion is dra\yn that the best lighting of potatoes in storage is 

 subdued daylight, which may be secured by painting the windows with lime 

 or covering them with white or gray paper. These lighting conditions, it is 

 stated, will reduce the tendency to sprout and prevent greening. Yellow, 

 blue, or red light was found as effective as subdued daylight, but dark green 

 light did not give the desired effect. Storage in tlie absence of light, especially 

 in spring and summer, aided the development of sprouts and is, therefore, not 

 recommended.
