3^ EXPEEIMENT STATION RECOED. 



These pages report the results of cooperative tests conducted in Ontario during 

 1910. Tlie work included variety tests of oats, six-rowed, two-rowed, and 

 hull-less barley, spring and winter wheat, buckwheat, field peas, soy beans, 

 emmer, spelt, mangels, sugar beets, Swedish and fall turnips, carrots, sweet, 

 fodder, and silage corn, millet, sorghum, gi-ass peas, vetches, rape, kale, field 

 cabbage, clover, alfalfa, grasses, field beans, early, medium-ripening, and late 

 potatoes, and winter rye. Fertilizer tests with oats, winter wheat, fodder 

 corn, mangels, Swedish turnips, and potatoes involved the use of nitrate of 

 soda, muriate of potash, superphosiihate, and a complete fertilizer, while cow 

 manure also was used with winter wheat, Swedish turnips, and potatoes. 

 These tests covered periods varying from 4 to 8 years. A table states the 

 average results reported from 5 tests of nitrate of soda, muriate of potash, 

 superphosphate, lime, and cow manure singly or in various mixtures in 1910 

 for barley. 



[Fertilizer tests on swamp soils], R. Haecoubt (Ann. Rpt. Ontario Agr. 

 and E.vpt. Union, 32 (1910), pp. 4^/, 45). — Applications of (1) acid phosphate 

 and sulphate of ammonia, and (2) acid phosphate, sulphate of ammonia, and 

 sulphate of potash were followed by yields of 96 and 176 bu. of potatoes, re- 

 spectively, as compared with 96 bu. per acre on the check plat. The tests were 

 conducted on swamp soils. 



[Adaptation experiments], J. H. Hampton (Rhodesia Agr. Jour., 8 (1911), 

 No. 6, pp. 8o3-SG2; 9 (1911), ISfo. 1, pp. 16-23, pis. 4).— These articles state 

 briefly the results of tests conducted to determine whether certain crops could 

 be profitably grown under southern Ehodesian conditions. The crops tested 

 were alfalfa, Egyptian clover, velvet beans, cowpeas, lupines, peanuts, sweet 

 potatoes, wheat, oats, millet, flax, mangels, sugar beets, swedes, kohl-rabi, car- 

 rots, rape, beans, peas, Paspalum dilatatum, Phalaris bulhosa, and sheep burnet 

 (Sanguisorha minor). 



[Fertilizer and variety tests], J. Johnston (Dept. Agr. Brit. East .'ifrica 

 Ann. Rpt. 1910-11, pp. 133-160). — These pages report the results obtained in 

 fertilizer, variety, and other tests with alfalfa, rape, corn, beans, wheat, man- 

 gels, sugar beets, ])eaR, potatoes, barley, Paspalum dilntatum, and flax. 



Supplementary pasture crops, M. L. Fisher and F. G. King (Indiana Sta. 

 Circ. 35, pp. 16, fig. 1 ) . — A general discussion of forage crops for the hog is fol- 

 lowed by special suggestions on growing for this purpose rape, cowpeas, soy 

 beans, Canada peas and oats, rye, oats, vetches, crimson clover, sorghum, arti- 

 chokes, mangels, sugar beets, carrots, and pumpkins. 



Tables suggest crops suitable for planting during each month from April to 

 October, information for use in planting each of a number of crops, and 

 crop successions for " hogging down " in Indiana. 



[Chemical and physical observations on Eritrea cereals], O. Manetti 

 (Agr. Colon. [liahj], 5 (1911), A^o. 3, pp. 100-113).— The crops dealt with are 

 SorgJmin vulgare, Eleusine coracana, Eragrostis abyssinica, and Pennisetum 

 spicutmn. Tables state date gathered in observations of the color, purity, ger- 

 mination, chemical composition, and specific gravity of the seed. 



Trials with grains and leg'umes for feeding purposes, 1899—1908, F. 

 Hansen (Tidsskr. Landhr. Plantcavl, 18 (1911), No. 4, pp. 485-542) .—The re- 

 sults of trials at 6 Danish experiment stations indicated that for feeding pur- 

 poses it is generally better to sow a mixture of 100 lbs. oats, 50 lbs. two-rowed 

 barley, 75 lbs. Gltino peas, and 25 lbs. vetches than to sow only a single crop. 



Barley alone or mixtures in which barley predominated gave the highest yields 

 on the best soils, while oats or mixtures consisting largely of oats yielded best 

 on the poorer soils.
