834 EXPERIMENT STATION RECORD. 



a depressing effect is observed. Consequently, it is concluded tliat ])arium and 

 strontium can not replace the antagonistic action of calcium." 



Tabulated data of the results of these experiments are given in terms of 

 length of leaf, length of root, and number of roots. 



On the composition of rice of Siam, G. Liberi {Ann. R. Staz. Chim. Agr. 

 Sper. Roma, 2. scr., 6 (1913), Xo. 2, pp. 225-2^6; a'bs. in Ztschr. Gesam. 

 Getreidew., 6 (1914), No. S, p. 61). — Some rices of Siam are classified into 3 

 tn^es. and data on the dimensions and weights of kernels of these types are 

 given. The lengths ranged from 4.94 to 8.58, the widths from 1.97 to 3.19, and 

 the thicknesses from 1.42 to 2.19 mm. 



Chemical analytical data are given in tabular form for about 30 samples 

 from these types and comparison is made with. Italian rice. 



On the influence of variety, preceding- crop, fertilizer, and stand upon the 

 yield of rye, Gerlach (Jlitt. Kaiser Wilhelms Inst. Landw. Brom'berg, 5 

 (1913), No. 5, pp. 360-402). — Tabulated data give results of tests of about 12 

 varieties covering the years 1900-1912. 



The results of a previous treatment of the soil showed fallow and lupine as a 

 green manure to be unprofitable, except that on sandy soil lupine could be 

 plowed under with profit. Good yields were obtained on clover sod, but the rye 

 was more frequently damaged by pests. Good results were obtained after barley 

 and oats, after an application of commercial fertilizers, and after early potatoes. 

 It is noted that the best results were obtained when the rotation was such that 

 the same crop did not always precede the rye. The small demands of the young 

 rye plant made a supply of nitrogen-furnishing fertilizer in the fall unneces- 

 sary, but a spring application of nitrate of soda proved remunerative. Seeding 

 at the rate of 120 kg. per hectare (107 lbs. per acre) with drill rows 12 to 15 

 cm. (4.7 to 5.9 in.) apart gave good returns. 



Soy beans in South. Africa, E. W. Thompson (Daily Cons, and Trade Rpts. 

 iU. 8.}, 16 (1913), No. 213, p. ^55).— This notes the trial of over SO varieties 

 of soy beans at the government experimental farms in South Africa, some 

 yielding 2,000 lbs. of beans and from 12 to 13 tons of green fodder per acre. It 

 is noted that altitude seems to affect the yield of oil, as beans grown at an alti- 

 tude of 3,354 ft. contained 20.65 per cent, at 500 ft. 21.36 per cent, and at 49 ft. 

 22.19 per cent of oil. 



A seven-year variety test with stock beets, 1904-1910, G. Bohmer (ArK 

 Deut. Landw. Gesell, No. 243 (1913), pp. F///-f 357).— This report gives data 

 on growth, total yield, yield of leaves, yield of dry matter in leaves and roots, 

 and percentage of sugar in tests carried on throughout Germany under the direc- 

 tion of the German Agricultural Society. 



Will annual comparison of the quality of sugar-beet seeds give desired 

 results? J. Urban (ZUclir. Zuckerindus. Bohmen, 37 (1913), No. 9, pp. 444- 

 j^^S). — From a 2-year test the author concludes that all beet seeds maintain 

 their relative quality in different years, this depending upon the inherited tend- 

 ency of the respective seed. In other words, a beet seed with the inherited 

 tendency to produce beets high in sugar will show this property in different 

 fields and in all seasons. 



On the influence of flowers of sulphur on the growth of sugar beets, 

 J. Urban (Ztschr. Zuckerindus. Bohmen, 37 (1913), No. 9, pp. 44^-^44) -—This 

 article gives a review of investigations along this line. The results obtained by 

 the author in applying flowers of sulphur at the rate of 200 kg. per hectare (178 

 lbs. per acre) immediately after planting sugar-beet seed showed a slightly in- 

 creased total yield, but no differences were observed in the color of the leaves 

 during growth, in the sugar content of the beets, or in the quality of the juice.
