FIELD CROPS. 641 



Field experiments at Grignon, P. P. Defierain {Ann. Agron., 26 {1900), No. 

 8, pp. 369-383). — Data secured in variety, fertilizer, and irrigation experiments with 

 jiotatoes, beets, sainfoin, and alfalfa during the unfavorable season of 1899 are recorded. 



Field crop tests, H. T. French {Idaho Sta. Bui 24, l^p. 13-18).— 'Notas and tal)U- 

 lated data on the successful culture at the station of potatoes, millet, and Dwarf 

 Essex rape. Of 13-t varieties of potatoes tested, the varieties Cream City, Ford No. 

 1, Large Puritan, Cambridge Prolific, and Rural New Yorker No. 2, with yields of 

 384, oa6, 349, 342, and 301 bu. per acre, respectively, were the most prolific sorts. 



Cost of growing corn, B. W. Sxow {Amer. Agr. {mid^ ed.), 65 {1900), Nos. 25, pi^. 

 739, 740; 26, p. 764; 66 {1900), iVo.s. 1, p. 4; 2, p. 28; 3, p. 52; 4, P- 76).— Statistical 

 data as to the cost of the various cultural operations in growing 4,051 acres of corn in 

 21 States. 



Culture experiments witli different varieties of lupines, Edler {Landiv. 

 WeluihL Sdde.'<irig-HoIsiein, 50 {1900), No. 30, pp. 5 18-5:.' 1).— Yellow, black, blue, 

 and white varieties of lupines were grown comparatively on sandy and sandy loam 

 soils. Data as to yields, time of blossoming, alkaloid and albuminoid content of the 

 seeds, etc., are recorded. 



Winter oats, M. Fischer {Fidding's Landic. Ztg., 49 {1900), Nos. 19, pp. 718-732,. 

 figs. 3; 20, pp. 766-771, figs. 3; 21, pp. 806-810). — The close relation between winter 

 oats and wild oats and the apparent frequent degeneration of the former to the latter 

 forms are discussed. 



Seed potatoes from different soils, Duke of Bedford and S. U. Pickering 

 ( Wohnrn Expt. Fruit Farm Bpt. 1900, pp. 236, 237, 258).— In this experiment tubers 

 which have been grown in one instance on light soil and in another on heavy soil 

 were used for seed in comparison with home-grown tubers. The yields obtained 

 from the home-grown tubers were on the average 8 per cent higher than those obtained 

 from the imported seed. 



Crops of potatoes obtained from sets of different sizes, Duke of Bedford 

 and .S. U. Pickering ( lYohurn ExpA. Emit Farm Rpt. 1900, pp. 233-235, i?.55).— Large, 

 medium, and small whole tubers of 3 different varieties were used for seed. The 

 best results in each case were secured from the medium size potatoes, the increase 

 being 24 per cent heavier than from small seed and 34 per cent heavier than from 

 large seed. No difference in the size of the tubers obtained from planting different 

 size seed was observable. 



The effect of planting potatoes at different times, Duke of Bedford and S. LT. 

 Pickering {Wohurn Expt. Fruit Farm Bpt. 1900, pp. 228-232, 2.58). — Planting pota- 

 toes in midseason — about the end of April — has given better average results than 

 planting either earlier or later. The Bruce has been the most satisfactory variety 

 grown. 



Sugar plants, L. Geschwind {Ann. Agron., 26 {1900), No. 8, p)p. 383-409) . — A 

 popular consideration of the nature of sugar-producing plants under the following 

 heads: (1) Plants containing sugar, but of little if any industrial importance, such 

 as carrots, melons, agaves, etc. ; (2) plants used in the production of sugar on a small 

 scale, like palms, corn, sorghum, and sugar maples; and (3) plants utilized in the 

 manufacture of sugar industrially, %. e., cane and sugar beets. 



The sugar-beet industry in New York, C. A. Wieting {Bpt. New York State 

 Dept. Agr., 6 {1899), I, pp. 101-118) .—The history of the development of the sugar- 

 beet industry in New York is briefly noted, and an account given of cultural experi- 

 ments in 1897 and 1898. The sugar-beet factories located at Rome and Binghamton 

 in the State are descrilied. 



• Conservation of beet tops {Deut. Landic. Presse, 27 {1900), No. 89, p. 1088). — 

 Different methods of conserving sugar-beet leaves for fodder, as drying, collecting in 

 heaps and fermenting, feeding green, etc., are considered.
