Sugar-cane experiments in Cuba (Agr. Neu [Barbado ,. \ 

 146). Among different new varieties of sugar cane under test in 1904, B 

 and Caledonia Queen ranked firsl in sugar content and purity. 



Variation in the chemical composition of the swede, S. II. (Joli ink 

 Agr. Sci., 1 {190.5), Vb t, pp. 89-107). This article summarizes the work of 5 

 with Bwedes and -how- the results of analyses of 14 varieties grown in differenl 

 localities. 



The individual root, its size, the fertilizers applied, the varief v, the season, and the 

 -nil and locality are discussed as factors influencing the composition. The relative 



in. Til of varieties was found to be fairly unifor ver a large area. The results show 



an average of 12.39 per cent of dry matter in swedes from the North of England. \ 

 li-i of the varieties in the order of merit, according to the percentage of total dn 

 matter based on the average of all results to the end of L904, is given. Pell Bronze 

 Top and Webb Imperial arc the leading varieties. 



The manurial requirements of the swede crop, .1. Percivai I 

 Reading, Agr._ Dept., Ann. Rpt. Field Trials <m<l Expts., 11 [1906 ,pp. / < I oop 

 erative fertilizer experiments were made with swedes. 



The fertilizers were used in quantities supplying the essential elements at the fol 

 low in- rate- peracre: Nitrogen 10, 20, and 4<» lbs. ; phosphoric acid 40, 80, ami inn |hs. ; 



ami potash 20, in, and 80 lbs. On nearly all farms tl mission of potash reduced 



the yields. The application supplying 40 lbs. of nitrogen, ion lbs. of phosphoric acid, 

 ami so lh-. of potash produced the largesl increase in crop. While the heavier 

 applications gave an increase in yield, the cost of this increase rose with the quantity 

 mi' fertilizers applied. The use of fertilizers seemed to improve the stand andthe 

 power of the plant- to resist insecl attacks. 



Experiments on the influence of fertilizers upon the yield of timothy hay 

 when grown on Dunkirk clay loam in Tompkins County, New York, .1 W 

 Gilmore and s. Fraser [New York Cornell Sta. Bui. 282, pp. 82 ?'• figs. 5 . The 

 chemical and mechanical analyses of Dunkirk clay loam soil upon which these experi- 

 ments were conducted are reported. In the fall of pan:; the plat- received commer- 

 cial fertilizers, stable manure, and lime, and the following spring they were Bown to 

 oat- and timothy at the rate of 9 pk. and 15 lbs. per acre, respectively. Commercial 

 fertilizers were again applied in the spring of 1905, but no manure and lime were used. 

 In 1904, 8 unfertilized plats produced 53.8 bu. of oats per acre, while 14 fertilized 

 plats produced 59.6 bu. The use of a complete fertilizer high in nitrogen ami phos- 

 phoric acid, and of 20 tons of sta hie manure per acre, was apparently mosl effective 

 in increasing the yield of oats; hut in these a- in all other cases the increase did not 

 pay i<>r the treatment. 



The yield of timothy hay in 1905 on s untreated plats was 2,160 lbs. peracre; on 

 :i plats receiving only mineral fertilizers, 2,890 lbs. ; on 8 plats treated w ith nit rate of 

 soda. 4,070 lbs. : ami on 2 plats receiving stable manure, 4. so.") ii.s. Two applications 

 of 320 lbs. each of nitrate of soda and acid phosphate and 80 lbs. of muriate of potash 

 per acre gave an apparent increase in yield of In.:; bu. of oats and 4,137 11'-. of tim- 

 othy hay. A Bingle application of 10 tons of Btable manure apparently increased the 

 yield of oats by •">.:; bu. and of hay by 2,595 lbs., and 20 tons of manure. 1»\ I 1.2 bu. 

 of oats and 4,0L'f> lbs. of hay per acre. From >i-r<\ in the ma mm- red and alsike clover 

 were introduced into the meadow. Estimating the cost of the manure at 50 eta. per 

 ton, the net gain from the use of 10 tons was $10.55, and from 20 tons $15.14. The 

 use of nitrogen in the fertilizers gave a marked increase in hay l»nt only a -ma;, in- 

 crease in tin- yield of oats. 



The results of the experiment are believed to indicate that if the proportion of 

 nitrogen to phosphoric acid had been 'greater the returns wouid have been more 

 profitable. Muriate of potash applied either alone or w ith nitrate of soda gave a net 

 gain. Lime had no influence on the growth of ti thy, but in other experiments
