748 EXPERIMENT STATION RECOED. 



lbs. dissolved bone black, 50 lbs. muriate of potash, and 240 lbs. nitrate 

 of soda per acre, "representing the full amount of phosphoric acid and 

 one-half the amount each of potash and nitrogen found in a crop of 25 

 bu. of wheat per acre." 



The yields obtained from the plats to which the phosphoric acid and 

 potash and phosphoric acid and nitrogen had been applied were nearly 3 

 times as great as those from the unfertilized plats. When applied in 

 combinations of 3 the proportions of the different elements were varied. 

 The standard amount of each element was decreased and increased by 

 one half and applied with the standard amounts of the other 2. The 

 increase and decrease of potash and nitrogen did not seem to have a 

 definite influence on the yield, but in the case of phosphoric acid the 

 yield varied in proportion to the amount supplied. Increasing the 

 standard application of phosphoric acid by one-half did not increase 

 the yield to a sufficient extent to warrant the practice. " On the whole 

 the indications are that fertilizers for this section should contain but a 

 small amount of nitrogen and potash but a large amount of phosphoric 

 acid."

 progress.

The composition of the seed of fodder beets, A. Devarda (Landw. Vers., Stat., 49 

 (1897), No. 3, pp. 239, 240). — The composition with reference to food constituents of 7

The sugar-beet industry (Nebraska State Bd. Agr. Bpt. 1896, pp. 217-399).— This 

 is in part a reprint of the papers and addresses presented at the meetings of the 

 Nebraska Beet Sugar Conventions held in 1896. A wide range of subjects was dis- 

 cussed, including the history and condition of the industry in this country and 

 abroad, the world's sugar supply and demand, experiences in sugar-beet culture by 

 practical men, and the growth and probabilities of the industry in Nebraska. 



A report by the State su^ar inspector on the campaigns of 1891-*95 shows the esti- 

 mated amount paid out by the factories for labor, beets, aud materials used in the 

 process of manufacture, and the total receipts for sugars. A partial list is given of 

 farmers who raised sugar beets, with the amounts they received for the crop, the 

 acreage, and the tonnage per acre. 



An address by an architect and designer of beet-sugar factories treats extensively 

 of the erection and operation of beet sugar factories in Nebraska. 



The methods of producing sugar-beet seed are outlined in an address on the pro- 

 duction of beet seed in the United States.

 Vers. Stat., 49 (1897), No. 3, pp. 193-202).— -This article has previously been abstracted 

 from another source (E. S. R., 9, p. 414). 



Methods of curing tobacco, M. Whitney (U. S. Dept. Agr., Farmers' Bui. 60, 

 pp. 15). — This bulletin describes the methods of curing Northern Cigar, White Bur- 

 ley, Bright Yellow, Export, and Perique tobacco, and the methods of curing tobacco 

 in Elorida. A classification and description of types of tobacco is given. The author 

 makes some suggestions regarding the marketing of tobacco.
