13^ EXPERIMENT STATION RECORD. 



elusion (hat electrocullure is not as yet far enough advanced to be applied in 

 practical agriculture. It is believed to be more promising in horticulture, 

 especially greenhouse culture, with strawberries, cucumbers, tomatoes, etc., 

 where an advance of about 14 days may secure large net i*eturns. Further 

 investigations, however, are considered necessary to determine whether the 

 installation of the necessary apparatus in greenhouses is remunerative. 



A bibliograjihy on the subject is presented. 



Report on 25 years' work by the agricultural institution at Rotholz, 

 1879-1904 (Bvricht iiber die 25 jdlinge Tdtigkeit tier LandwirtschaftHchen 

 Laiidesanstalt Rotholz von ihrer Griindung im Jahre 1879 Ms 190/f. Innshruck, 

 190^, pp. 150, pis. 8, figs. 18, dgms. 5). — This publication contains a historical 

 review of the institution, outlines the courses given in agriculture, and reports 

 some of the results secured in experimental work, this being based mainly on 

 studies of problems connected with Alpine agriculture. 



Report of work with, barley, peas, and vetches at Svalof in 1909, H. 

 Tedin (Sveriges Vtsddcsfor. Tidskr., 20 {1910). No. 4, pp. 2 .'i 5-255 ; ahs. in Bot. 

 Centl)!., 116 {1911), No. 6, p. 160).— In a test of 27 2-row barleys 0219 and 0202 

 Svalof Gullcorn produced the highest yield. In a test of 12 6-row barleys at 

 Svalof and Lonnstorp Nordschlesowigst Jatte and Tystofte 27 produced the 

 highest yields. 



Alfalfa management in Montana, A. Atkinson {Montana 8ta. Circ. 5, pp. 

 72). — Directions for producing alfalfa and alfalfa seed in Montana. 



The time of applying' potash salts in buckwheat culture, Claussen 

 {IllKS. Lundw. Ztg.. 31 (1911), No. 10, pp. 73, 7',. figs. 5).— The results here 

 reported were secured during 2 years of work. 



The use of kainit in the spring reduced the yield by about one-half, while its 

 application in the fall was not injurious but was of indifferent value. It was 

 found that kainit as a fertilizer for buckwheat was of value only when applied 

 to the preceding crop in the rotation. 



Corn judging', R. J. Nelson {Univ. Ark. Col. Agr., Circ. 1, 1909, pp. 3-7). — 

 This is a circular of information for the members of the boj^s' corn clubs of 

 Arkansas. A score card for corn and directions for selecting an exhibit of 

 seed corn are followed by notes on the score card and its use. 



Corn and cotton, M. Nelson {Univ. Ark. Col. Agr., Circ. 3, 1910, pp. 8). — 

 Methods for producing corn and cotton are briefly outlined. 



Experiments with cotton, J. F. Duggab and E. F. Cauthen {Alahama Col. 

 Sta. Bui. 153, pp. 15-'i0, pis. I/). — Among the cotton varieties tested on plats in 

 1910 Cook, Dillon, Hardin, and Triumph yielded best ; " in observation rows, 

 Bate Early Victor, New Triumph, Excelsior Wilt-Resistant, Triumph from 

 Alabama, and Franklin all yielded well." The earlier varieties were Early 

 IMammoth, Broadwell, Bank Account, Trice, Sugar Loaf King, and Shelley, 

 while Hardin, Dillon, Pouluot, and Russell were among the later varieties. 



Larger yields followed the use of acid phosphate than were obtained after 

 ground rock phosphate or basic slag. Rowden, Cleveland, Dixie, Simpkins, 

 Dillon, and Pouluot were among the varieties least damaged by anthracnose. 



Seed treatment reduced the amount of boll-rot or anthracnose. Immersion of 

 seed in water at 170° F. for 10 minutes was followed by a crop having only 4.9 per 

 cent of the bolls diseased as compared with 11.3 per cent from the untreated 

 seed. The crop secured from seed treated for 22 minutes at a temperature of 

 150° had 2.4 per cent boll-rot as compared with 9.9 per cent from untreated 

 seed on an adjacent plat. When the seed coat was charred with concentrated 

 sulphuric acid the percentage of diseased bolls was apparently reduced from 

 11.3 to 5.9. With formalin 4 and 5 per cent, copper sulphate, and carbon bisul- 

 phid, the percentages diseased were larger.
