FIELD CROPS. 331 



work has been completed on soil and crop requirements with fertilizers, variety 

 tests of corn, wheat, oats, and potatoes, and on cultural and other tests. 



Report of cooperative field and fertilizer trials in Dalarna and Norrland, 



1909, S. Rhodin (E. Lancltbr. Akad. nandl och Tidskr., 49 {1910), No. 8, pp. 

 657-690, flgs. 2). — The author gives an account of the tests conducted by county 

 agricultural societies in northern Sweden, covering 224 different experiments 

 with cereals, roots, pasture, and fertilizers. 



Report of the Temir Experiment Field in the Turay-Ural region in the 

 years 1907—8, S. K. Chaianov {Ahs. in Zhur. Opytn. Agron. (Riiss. Jour. 

 Expt. Landiv.), 11 {1910), No. 4, pp. 592-593). — The experience of the year 

 showed that it is possible to raise cereals on the clays and sand of the Terair 

 district, but the yields in 1907 were generally low owing to winds and weather. 



[Experiments with field crops], W. R. Gourlay {Rpt. Agr. Dept. Bengal, 



1910, pp. 2-6). — Brief reports are given of experiments in growing jute, cotton, 

 flax, spineless cactus, rice, wheat, potatoes, corn, sugar cane, peanuts, and other 

 crops. I 



[Fertilizer tests on grass land, including cooperative work], F. W. Tay- 

 lor {New Hampshire Sta. Bui. 151, pp. 16, 17, 19, 20).— During the period 1907 

 to 1910, inclusive, the highest comparative average j'iekls of hay per acre in 

 the fertilizer tests with 12 fertilizing materials on grass land (E. S. R., 21, 

 p. 730) were 3.115 and 2.7 tons of hay per acre, respectively, after (1) 400 lbs. 

 and (2) 200 lbs. of nitrate of soda. 



In cooperative experiments on 7 farms average yields of 4,137, 3,901, and 3,158 

 lbs. of hay, respectively, were secured from the nitrate, complete fertilizer, and 

 manure plats. The check plats gave an average yield of 2,288 lbs. per acre. 



Fertilizing permanent marsh pastures, Hinrichs {Deut. Landw. Presse, 

 3S {1911), No. 36, pp. J, 17, //i8).— Results of fertilizer tests here reported show 

 that ammonium sulphate gave excellent results on run-down marsh pastures, 

 but was of no benefit on fairly productive pastures, whereas phosphoric acid 

 and lime fertilizers did benefit the latter. 



Alfalfa management, C. W. Pugsley {Nebraska Sta. Bui. 120, pp. 3-13). — 

 The author gives " explicit instructions in regard to the seeding and care of 

 alfalfa," including a discussion of soils, seeding, inoculation, cultural practices, 

 manuring, seed production, hay, and pasture. 



The tillering power of barley, H. Tedin {Sveriges Utsddesfor. Tidskr., 19 

 {1909), No. 6, pp. 292-312; al)s. in Bot. Centbl, 114 {1910), No. 10, pp. 255, 

 256). — The same varieties of barley were observed to vary in tillering capacity 

 in different seasons. 



Four-rowed barley in general did not tiller as strongly as the two-rowed varie- 

 ties. The differences between varieties in the same class were as a rule much 

 smaller than differences resulting from weather conditions, space between 

 plants, and other similar factors. Close planting diminished the tillering power 

 and the use of heavy seed as compared with small seed increased it. 



Tests of some improved varieties of barley, J. J. Vanha {Ztschr. Landw. 

 Versuchstv. Osterr., 13 {1010), Nos. 7, pp. 634-665; 8, pp. 675-698; 9, pp. 758- 

 78.5).— More than 30 varieties of barley were tested and the data secured include 

 the weight per hectoliter, uniformity of grain, kernel weight, percentage of hull, 

 structure of the endosperm, germinative power, protein content, and starch con- 

 tent. Among the varieties tested were many newly developed sorts. 



At the experiment station in Briinn, a comparison was mnde of 85 pure-bred 

 strains. In these the protein content ranged from 9.34 to 12.08 per cent, the 

 starch content from 59.23 to 64.08 per cent, the thousand-kernal weight from 

 41.61 to 54.45 gm., and the proportion of huU from 9.31 to 12.35 per cent. The
