56G EXPERIMENT STATION RECORD. 



The coinpositioii of the cane and of the different parts of the plant, the mineral 

 matter an<l nitrogen taken out of the soil, and the quantities of nitrogen, pliosphoric 

 acid, potash, and lime used per ton of sugar grown aregivenin tables for each variety. 



Chlorids in tobacco, W. H. Pegram {Ahs. -in Science, v. ser., 17 {1903), No. 4IS, 

 p ^^^v).— The Avork set forth in this paper was designed and is being prosecuted for 

 the purpose of ascertaining whether there is a relation between the chlorids in 

 tobac:co and the chlorids in the fertilizer used in its production; also whether a high 

 percentage of chlorids (as calcium and magnesium chlorids) affects the hygroscopic 

 property of tobacco, giving abnormal and damaging results at certain stages of its 

 ])rei)aration and manufacture. The data are insufficient as yet to justify a valid 

 coiichision. 



Experiments with wheat at Grignon in 1902, P. P. Deherain and C. Dupont 

 {Semaine Agr., H^ {190-£), No. 1121, p. 35.5). — Of 5 different varieties Japhet produced 

 the largest yield of grain, 50.1 quintals per hectare, followed l)y Massy with a yield 

 of 43.1 quintals. The latter variety i)roduced the largest yield of straw, 97.6 quintals 

 per hectare. The yields of all varieties, owing to favorable moisture conditions, were 

 quite large. The fertilizers were ajiplied broadcast and in drills and tlie results were 

 slightly in favor of the drill api)lication. 



HORTICULTURE. 



Report of the assistant in horticulture, A. T. .Jordan {Neiv leneij Slaf!. Rpt. 

 1901, pp. 215-268). — The author gives the results of another year's experiments to 

 determine the effect of irrigation and the relative effects of fertilizers with and with- 

 out irrigation upon the early and total yields of asparagus, blackberries, raspberries, 

 strawberries, currants, and gooseberries. A similar report was given in 1900 (E. S. R., 

 13, p. 738). A further study of the value of an additional amount of 200 lbs. of 

 nitrate of soda for some of these crops has been made and variety and fertilizer tests 

 conducted with plums, cherries, dwarf and standard pears, and peaches. Tests of 

 some newer varieties of bush fruits and of subirrigation experiments with them are 

 also recorded, together with tests of a number of varieties of vegetables, of large v. 

 small tomato seed, and of early and late starting for tomatoes. A table showing the 

 daily and monthly precipitations for the year is included. 



In the experiments with asparagus Palmetto yielded 33 lbs. more of early stalks 

 antl 1,512.7 lbs. more of total cut than any of 5 other varieties tested. The early 

 yield was largest in every instance on the unirrigated plats, while in 3 out of 4 cases 

 the total yield was largest on the irrigated plats. The total results of 4 years, during 

 which the experiments have been under way, show a greater cut of early asparagus 

 from the unirrigated plats than from the duplicate irrigated ])lats. The total cut, 

 however, has been slightly larger from the irrigated j^lats. The advantage shown in 

 the earlier years of the experiment from setting large selected crowns of asi)aragus has 

 now entirely disappeared. The yields obtained by applying barnyard manure at the 

 rate of 20 tons per acre have been greater than from the use of 500 lbs. of complete 

 commercial fertilizers applied in the spring, or from 300 lbs. of bone and potash 

 applied in the fall with 500 lbs. of complete commercial fertilizers applied in the 

 spring, or from these same commercial fertilizers plus 200 lbs. additional of nitrate 

 of soda applied at the time of cutting. 



With blackberries the early yield during the 4 years of the experiment has aver- 

 aged 22 per cent better on the irrigated than on the unirrigated plats, and the total 

 yield 13.3 per cent better. The effects of the different fertilizers have been irregular. 

 In 1901 Early Harvest gave by far the largest early yield of 6 varieties tested, as well 

 as the largest total yield. Eldorado stood a close second as to total yield, but pro- 

 duced scarcely a third as large early yield as Early Harvest.
