FIELD CROPS. 541 



Preservation of crops, J. W. Sanborn ( Utah 8ta. Bpt. 1893, pp. 

 32-37). — The expeiimeuts wliicli are detailed in preserving coru fodder, 

 clover liay, wheat, and timothy hay. gave the following results: 



" (1) Unweighted silage met with a loss of 29.28 per cent. 



" (2) Weighted silage met with a loss of 7.28 per cent, asnialler loss than is usually 

 reported. 



" (3) Corn fodder in the loft met with a loss of 21.3.") per cent, a greater loss than 

 is commonly reported. 



"(4) Clover hay, whether stacked out doors, housed in the harn, or suspended in 

 small lots in bags, showed no loss either from fermeutatiou or from oxidation. 



" (5) "Wheat gained in total weight by winter storage. 



" (6) Timothy hay showed no loss save that housed in the barn, and this loss prob- 

 ably may be traced in part to faulty sampling or faulty analysis, and amounts to 

 about 10 per cent." 



Rotation of crops, J. W. Sanborn ( Utah 8ta. Bpt. 1893, pp. 74-85). — 

 The data obtained during 4 years in experiments with a 2-years' 

 rotation, a 4-years' rotation, and a 6-years' rotation are recorded as a 

 report of progress, and portions of this data, together with the theory 

 of rotation, are discussed. The crops grown were wheat, clover, pota;- 

 toes, barley, and timothy. On check plats these crops were grown con- 

 tinuously. Generally rotation increased the yield, but sufficient time 

 has not yet elapsed to permit of definite conclusions regarding the 

 amount of increase due to rotation and the relative advantages of the 

 several rotations. 



On certain plats of the 6-years' rotation series the percentages of 



moisture in the soil and the temperatures at different depths were 



determined and the results tabulated. On the plat on which wheat 



was grown the soil temperature at a depth of 3 in. was considerably 



• higher.than at the same depth on the plat growing clover and timothy. 



Twenty-five years of plant breeding, Rimpau {Bent, landw. Presse, 21{lS94),No. 

 98, p. 11). 



Report on culture experiments ■with barley in Schles-wig-Holstein in 1892, 

 A. Emmkrling and H. Gottsch {Landw. Wochenhl. Schles. Hoist., 43 {1S94), No. 50, 

 pp. 707-709). 



Variety test of barley, A. A. Mills ( Utah Sta. Bpt. 1893, pp. 2S8-232) .—The 

 yields obtained in 1890, 1891, 1892, and 1893 are tabulated. The variety Lump Blue 

 gave the largest average jneld (25. .57 bu. per acre) and the largest single yield. 



Green manuring for barley, J. W. Sanbokx ( Utah Sta. Bpt. 1S93, pp. 173-175). — 

 A crop of peas i^lowed under in 1893 increased the crop of barley in 1893 from 7.22 

 bu. per acre to 22.56 bu. Wheat used as green manure failed to increase the yield 

 of the following croj).

 fig- !)■ 



Practical canaigre culture, C. B. Alliare {Irrigation Age, 7 {1894), No. 5, 

 p. 226). — The need of extending the market is pointed out, the dry roots being only 

 $40 per ton in Hamburg and LiveriJool. Canaigre is claimed to be an excellent sub- 

 stitirte for gambler and other high-grade tanning materials. It is easily grown and 

 docs not require more than 6 inches of water. As far as known it has no insect 

 enemies.
