230 EXPERIMENT STATION RECORD. 



tween these two foods wlieu they were fed to bullocks in feeding-boxes and 

 subsequently carted out to the field as farmyard manure and used fcr growing 

 a root crop." This experiment was begun in 1904 and a general summary of 

 results and conclusions is deferred until all rotations in the series have com- 

 pleted their course. The rotation practiced in connection with this work is as 

 follows: Mustard as a green crop, swedes, barley, wheat. 



As in the two previous years 1 cwt. each of nitrate of soda and of salt per 

 acre gave a slightly better yield of mangels than either 1 cwt. or 2 cwt. of 

 nitrate alone. 



Apparently t-he best application per acre for alfalfa consisted of 4 cwt. each 

 of superphosphate, bone dust and sulphate of potash, and 2 cwt. of nitrate of 

 soda. The plat receiving this application yielded a trifle over 19 tons, 16 cwt. 

 of green ci'op per acre. Canadian alfalfa seed gave much better results than 

 either American of Provence seed. 



In the improvement of old pasture on Broad Mead the use of 10 cwt. of basic 

 slag and 1 cwt. of nitrate of potash per acre gave the best returns in 1905, and 

 that of 10 cwt. of basic slag and 1 cwt. of sulphate of potash in 1907. The 

 greatest amount of leguminous plants was found on the plats receiving per acre 

 5 cwt. of superphosphate and 1 cwt. of sulphate of i)Otash and those receiving 

 the basic slag and sulphate of potash. 



On Long Mead in 1906 the plat treated with 5 cwt. of superphosphate and 

 4 cwt. of kainit per acre ranked first in yield of hay, but the increase was small. 

 Lime u.sed alone remained without apparent effect. In 1907 the highest yield 

 was secured on the plat treated with 5 cwt. of mineral superphosphate and 

 1 cwt. of sulphate of potash per acre. 



Thirty-first annual report of the seed control and experiment station at 

 Zurich, F. G. Stebler (Landw. Jahrh. Schiveiz, 23 {1909), A'o. 1, pp. 1-24, 

 figs. 3). — In 1908, 10,.33.5 samples of seed were sent in which required 25,79o 

 tests. Tlie different ijoints determined were degree of adulteration, purity, 

 vitality, and cuscuta content. The average results secured from 1876 to 1908 

 with different varieties of clover, grasses, forage crops, leguminous plants, 

 cereals, fiber crops, root crops, vegetable and forest seeds are tabulated. Brief 

 notes on the seed of different kinds of plants examined during recent years are 

 given. 



Reports are also given on numerous culture tests with forage crops carried 

 on throughout the country. Sainfoin seed fi-om southern Russia did not give 

 as good results as seed obtained from Arabia. Inxiculated serradella gave a 

 yield from three to four times as large as serradella grown without inocula- 

 tion. The statement is made that tlie inoculating material now found upon the 

 market is much more effective than formerly. 



The Alpine experiment g'arden on the Sandling-Alp, T. von Weinzierl 

 (Pub. K. E. SamcH-KontroU Stat. Wie.ii, No. 376, pp. 21, figs. 5, chart 1). — A 

 description is here given of this Alpine station and the different lines of work 

 pursued are briefly outlined. 



The composition of the herbag'e on permanent meadows under different 

 treatment, E. Lindhard (Tidsskr. Laiidbr. Planteavl, 15 (1908), 2Vo. 4, pp. 

 467-503). — Comparisons were made l)etween 4, 3, and 2 cuttings during the 

 season. 



The largest amount of total dry matter was obtained when 2 cuttings were 

 made with a relatively late first cutting, the dicotyledons being cut during the 

 first half of the blossoming period and the grasses from lialf to full bloom. 

 The quality of the crop was greatly dependent on the time and the number of 

 cuttings. On May 20 the nitrogen content was 2.05 and 2.18 per cent for the 2
