142 EXPEEIMENT STATION RECORD. 



by de Vries were produced. He expresses the conviction tliat the specific char- 

 acters described for the various species are simply individual variations due to 

 a tendency to degeneration in consequence of the plants having been transferred 

 from a xerophytic (sandy) environment to a soil supersaturated with manure. 



FIELD CROPS. 



[Field crops work at the North Platte substation] (Nebraska Sta. Rpt. 

 1909, PI). XIV-XVI). — During the 4 years beginning 1906, summer-tilled land 

 produced an average of about 50 bu. per acre. Adjoining fields not summer 

 tilled yielded from 20 to 24 bu. per acre, except in the unusually wet season of 

 1906, when they produced 41 bu. per acre. The middle of September proved 

 the best time for sowing winter wheat. Durum wheat varieties yielded from 

 26.5 to 33.6 bu. per acre in 190S and proved much superior to the local varieties 

 generally used. No other variety excelled common barley with its yield of 21.4 

 bu. per acre. Among 12 oat varieties, Kherson produced 42 bu. per acre and 

 Burt and Texas Red 38 bu. each. 



Beport on the Aligarh Agricultural Station of the United Provinces of 

 Agra and Oudh for the year ending June 30, 1910, A. E. Parb (Rpt. Aligarh 

 Agr. Sta. United Prov. Agra and Oudh, 1910, pp. 5+II, pi. 1). — American cot- 

 ton sown early with irrigation produced nearly twice as great a yield as that 

 sown later with the rains, while the local varieties showed little difference. The 

 local varieties gave practically equal yields when sown broadcast as when sown 

 in rows 2 ft. apart. Among local varieties Bisawar produced the highest yield, 

 411 lbs. per acre, but was only moderately high in lint percentage. Other work 

 reported dealt with plant selection in cotton tests, local adaptability of ground- 

 nuts, rates of sowing maize, and variety tests of sugar cane and maize. 



Variety tests of wheat and oats, J. L. Burgess, F. T. Meacham, and R. \V. 

 CoLLETT (Bui. N. C. Dcpt. Agr., Aug. 1910, Sup., pp. 11).— Among wheat varie- 

 ties tested at the Iredell Farm in 1910. Fulcaster and Miller Choice stood first 

 with yields of 26.1 and 25.7 bu. per acre respectively, while Culberson and 

 Apler oats yielded 51 and 46 bu. per acre respectively when sown in the fall, 

 and Hood Mammoth and Burt Ninety Day stood first among the spring sown 

 oats with yields of 40 and 34.3 bu. per acre respectively. Six varieties produced 

 an average yield from fall seeding much above that of the same varieties when 

 sown in the spring. At the Buncombe Test Farm, Merridy and London native 

 varieties of wheat yielded 14.8 and 12.9 bu. per acre respectively. 



Winter fodders for the south coast, R. N. Makin (Agr. Gas. N. S. Wales, 

 21 (1910), No. S, pp. 686-690, figs. )). — The author reports results of tests of 

 different varieties of wheat, oats, rye, and barley for winter fodder. 



Report on rice and cotton investigations in China and Japan, F. G. Krauss 

 (Hawaii. Forester and Agr., 7 (1910), Nos. 5, pp. 14S-152, pis. 3; 6, pp. 186-193, 

 figs. 6; 7, pp. 210-220, figs. 6; 8, pp. 231-238; 9, pp. 271-275).— These articles 

 report the methods used in rice and cotton production in China and Japan, the 

 experimental methods in use at the stations of these countries, and some gen- 

 eral conclusions based upon their investigations. 



Trial of leguminous plants from Ceylon (Agr. Gaz. N. S. Wales, 21 (1910), 

 No. 8, p. 670). — The results are briefly reported of a test of Crotalaria striata, 

 C. hirsuta, C. laburnifolia, and Indigofera rubra. The two last-named failed to 

 germinate. The first-named yielded a small iimount of thick, coarse fiber and 

 possessed no commercial value, although grown for its fiber in Chutia Mazpur. 



Cold resistance of alfalfa and some factors influencing it, C. J. Brand and 

 L. R. Waldron (U. S. Dept. Agr., Bur. Plant Indus. Bui. 185, pp. 80, pis. !,, fig. 

 1). — The experiments reported were conducted at Dickinson, N. Dak., in co- 

 operation with the North Dakota Station.
