36 EXPERIMENT STATION EECORD. 



The higher rates of fertilization produced the higher yields and profits 

 within the limits of the test. The use of poultry manure was followed by 

 higher yields than any other application except a mixture of 2 parts of super- 

 phosphate, G parts wood ashes, and 2 parts of Chile saltpeter. In net gain it 

 greatly surpassed any other application tested. 



The sug'ar beet industry in Nevada, C. S. Knight (Nevada 8ta. Bui. 15, 

 pp. 9-38, figs. 18). — A statement of the climatic and soil requirements of the 

 sugar beet is followed by directions for producing the crop. Especial em- 

 phasis is laid on methods of irrigation and extended quotations are given from 

 Farmers' Bulletin 392 (E. S. R., 23, p. 140). Tables give the analyses of 

 beets grown at the station farm in 1910 and in other portions of the State 

 during 1909 and 1910. 



[Variety tests and analyses of sug'ar cane], L. G. Coerie (Ann. Rpt. Queens- 

 land Acclim. Soc, Jjl (1910), pp. 7-10). — The conditions were unfavorable for 

 high or even average sugar content in any cane, and the 17 highest results 

 obtained from the society's seedlings ranged fi'om 16.02 to 17 per cent of sac- 

 charose. The saccharose of 6 West Indian seedlings ranged from 17.32 to 

 20.26 per cent in 1907, and from 12.52 to 17.40 per cent in 1909. Each variety 

 gave a lower yield In 1909 than in 1907. The standard variety, Rappoe, 

 yielded 13.93 per cent. 



The composition of wheat, J. W. Ames (Ohio Sta. Bui. 221, pp. 37, pi. 1).— 

 This bulletin presents analyses of wheat crops grown on soils on which fertility 

 tests have been coudvicted for 15 years, as previously noted (E. S. R., 20, p. 428), 

 the wheat being grown under various climatic and soil conditions and methods 

 of fertilization. A wide variation was noted in the phosphorus, potassium, 

 and nitrogen contents of the wheat crop analyzed. On unfertilized plats of 2 

 soils differing as to these elements the composition varied in accordance with 

 that of the soils. Their addition to the soil was followed by an increase in 

 the proportion in which they occurred in the wheat plant. Variation due to 

 seasonal conditions was greater than that resulting from changes in soil com- 

 position but those due to soil treatment were " relatively the same for the dif- 

 ferent seasons." 



The addition of phosphorus to a soil deficient in this element increased the 

 amount of phosphorus in the grain. The quantity of potassium was also in- 

 creased but that of nitrogen decreased. Similar results followed the addition 

 of lime. The use of barnyard manure increased the phosphorus content of 

 the wheat plant to a greater extent than did acid phosphate, bone meal, dis- 

 solved bone black, or basic slag, and the use of untreated rocli phosphate on 

 a soil rich in nitrogen and potassium markedly increased the phosphorus con- 

 tent of the plant. The nitrogen content of the plant varied with the supply 

 of .this element and was also influenced by the supply of phosphorus. The 

 potassium content of the straw varied with that of the soil on which it grew. 



The improvement in the quality of wheat exported from the Central 

 Provinces, G. Evans and A. E. Humphries (Cent. Prow \India'], Agr. Dept. 

 Bui. //, 1910, pp. Ui). — The wheats grown in the Central Provinces are of two 

 classes, Pissi or bread wheats and Gehun or macaroni wheats. This paper 

 reports the results of tests of 4 bread wheats of which Raipuri Pissi was 

 strongest but lowest in nitrogen content. Deshi Pissi was most lacking in 

 strength but produced the highest yield, 740 lbs. per acre. 



An examination of the seed supply of the Broach District, G. D. Mehta 

 (Dept. Agr. Bombay Bnl. 37, 1910, pp. 18). — Tables state the number of seed 

 samples of each species examined and the percentages of purity, germination 

 capacity, and useful seeds found.
