832 EXPERIMENT STATION RECORD. 



Loss in weight of stored potatoes, Denaiffe (Jardiii, 21 {1901), No. J/Sl, 

 pp. 16-19, figs. 2). — The results of observations made show that the loss in 

 weitrlit during storage varies with the variety and is not the same for all 

 montlis. Of tlie varieties studied the loss was about 1 per cent per mouth, or 

 about 7 per cent from the time of harvesting until June 1. The loss was greatest 

 in the varieties grown for the table, especially in the early sorts, and less in the 

 potatoes grown for forage or industrial purposes. The early table varieties lost 

 about 8 per cent during the storage period, while the other sorts lost only about 

 Hi per cent. 



Results of culture experiments in 1906 at the German potato experi- 

 ment station {Dent. Landiv. Fresse, S^ {1901), No. 13, pp. 100-102).— Twenty 

 varieties under test gave an average yield of 24,770 kg. of tubers and 4,-J:00 kg. 

 of star<'li per hectare, the average starch content being 17.9 per cent. The 

 variety Professor Wohltmann ranked first in yield of tubers with 29,560 kg., 

 and also first in yield of starch with 5,810 kg. per hectare. Brocken stood 

 highest in starch content with 20.5 per cent. 



Results of r. Heine's potato culture experiments in 1906 {Deuf. Liuidic. 

 Prcssc, S.'t {1901), No. IJ,, pp. 109-111).— Ot 99 varieties tested, Ilildesia, Eduna, 

 and Sas ranked first in yield. Fiirst Bismarck, which stood fifth in yield, 

 ranked first in yield of starch and. starch content. Notes on different varieties 

 with reference to their suitableness for culinary and industrial purposes are also 

 given. 



Rice culture, R. J. Nelson {ArLaiisas SUi. Bui. 9.'f. pp. 31-.'i5). — It is stated 

 that the acreage of rice in Arkansas increased from 450 acres in 1905 to about 

 5,000 acres in 190G. At the station rice was sown at the rate of 1^ to lA bii. per 

 acre on different dates from April 20 to May 10. The earliest sowing produced 

 the maximum yield, 77.7G bu. per acre. The irrigation period of this crop was 

 84 days. The Honduras variety produced at the rate of 01.84 bu. and the Japan, 

 52.44 bu. of rice per acre, the average being 57.5 bu. 



Notes are given on the history and food value of rice, together with directions 

 for rice culture in general. 



Sugar beet growing experiments in England, Scotland, and Ireland, 1906 

 {Internat. Sugar Jour., 9 {1901), No. 98, pp. S//-5i). — The analyses of 157 sam- 

 ples of sugar beets are given in tables. The average sugar content of the 

 samples was 15.46 per cent. The juice constituted 93.12 per cent and the pulp 

 6.88 per cent of the beets. 



Injurious effect of nitrogen in the sugar beet, K. Andrlik {Ztschr. Zuclc- 

 criiidus. Bohmcii, 31 {1901), No. 5, pp. 211-28.^). — The results of experiments 

 show that the presence of nitrogen in the beet may reduce the quality of the 

 juice and be detrimental to the manufacture of sugar. The quantity of injuri- 

 ous nitrogen found in the root varied with the kind of seed. The use of a single 

 nitrogenous fertilizer, whether in the form of nitrate or ammonia, increased 

 the quantity of nitrogen in the beet, but the use of barnyard manure up to about 

 27 tons per acre under conditions of a normal rainfall produced no injurious 

 effect. When a heavy application of nitrate of soda up to about 1,000 lbs. 

 per acre is made the injurious effect may be largely reduced by the addition of 

 potash and superithosphate. 



Experimental work in the production of table sirup at Waycross, Ga., 

 1905, II. W. Wiley {U. 8. Dept. Agr., Bur. Chciii.-Bul. 103, pp. 3S).— The 

 plan of the fertilizer experiments with sugar cane here reported has been pre- 

 viously described (E. S. R., 17, p. 458). The results for 1905. the last year 

 of the work, are given in this bulletin together with a summaiy of the entire 

 4-year experiment.
