228 EXPERIMENT STATION EECOED. 



from 7.7 to 1G.4 bu. in a dry season. With barley tbere was an increase from 

 18.1 to 30.8 bu. in a dry season, while in a wet season the increase was only 

 6.5 bu. 



[Variety and manurial experiments in Ireland], J. Wilson (Trans. High- 

 land and Agr. Sog. Soot., 5. set:, 2Jf {1912), pp. 3-39). — The author, in com- 

 paring the tabulated results with potatoe.s, mangels, turnips, oats, and meadow 

 hay, points to the results as showing the benencial use of commercial fertilizers. 

 The highest profits, £5 7s. 6d., were received for mangels, with the greatest 

 amount of commercial fertilizer (2 cwt. ammonium sulphate, 4 cwt. salt, and 

 4 cwt. superphosphate) in combination with 20 tons of barnyard manure per 

 acre. 



Report of a variety test with oats, spring' wheat, field beans, fodder beets, 

 and sugar beets, F. Merkel (Arb. Deut. Landw. GeselL, 1912, ls!o. 223, pp. 

 319). — This report consists chiefly of tabulated results obtained in 1911 by 

 numerous members of the German Agricultural Society in cooperative variety 

 field tests, giving data as to the kind of soil, previous 3-year ci'ops, amount and 

 kind of fertilizer applied, date of seeding and harvest, amount of seed used, 

 amount of damage by insects and fungi, weather conditions, yields, weight of 

 1,000 kernels and of 1 liter of grain, and percentage of hulls of each of the 

 numerous varieties grown. 



[Wheat, oats, and potato tests], A. Despeissis {Dept. Afjr. and Indus. West 

 Aust. Ann. Rpt. 1911, pp. 8-11). — Tabulated results of yields of numerous 

 varieties of wheat show a yield of from 0.1 to 2(i.6 bu. of grain per acre, or 

 when cut for hay a yield of from 2 to 3 tons per acre. 



In a manurial test, using quantities purchasable for the Siime amount, an 

 expenditure of 8s. 3d. for 224 lbs. superphosphate was followed by a yield of 

 10 bu. of wheat per acre, as compared with 15.5 bu. following the use of 280 

 lbs. basic slag. 



The use of 1G8 lbs. superphosphate was followed by a yield of 13 bu. and 

 that of 210 lbs. basic slag by 11 bu., while the respective yields with 112 lbs. 

 superijhosphate and 140 lbs. basic slag were 12 and 10. .5 lbs. 



Yields of oats varieties, ranging from 9 to 20 bu. per acre, are also given. 

 An average yield of potatoes of 3 tons 4 cwt. per acre was obtained, as com- 

 ])ared with 5 tons 15 cwt. in Great Britain, 3 tons 18 cwt. In Ireland, and 

 7 tons 3 cwt. in Scotland. 



Annual report of the Dumraon Agricultural Experimental Station, 

 1911-12, G. Sherrard {Ann. Rpt. Dumraon Agr. Sta. [India], 1911-12, pp. 

 13). — Experiments showed the gain in yield of sugar cane to be as high as 

 1,380 lbs. per acre by the trench method of planting in comparison with the 

 local systems. Ck)w manure ashes apparently increased the yield of rice 1,100 

 lbs. of grain and 4,165 lbs. of straw per acre over the rnmanured plats, whereas 

 green manuring increased the yield 1,076 lbs. of grain and 4,715 lbs. of straw 

 per acre. 



Tabulated results of fertilizer and variety tests of rice, and variety tests of 

 wheat and mustard are also given. 



Legume inoculation, M. J. Prucha {New York Cornell Sta. Circ. 15, pp. 

 25-32, figs. 5). — This circular discusses briefly the essential facts as to inocula- 

 tion of legumes and calls attention to the pure cultui'es which the department 

 of plant physiology is now distributing. 



Report of assistant botanist, J. Belling (Florida Sta. Rpt. 1912, pp. CXY- 

 CXXIX). — This pai)er reports of planting the second generation of seeds pro- 

 cured by crossing the Velvet and Lyon beans, continuing earlier work (E. S. R., 

 27, p. 338).
