Results of cooperative exiaerinients in agriculture, C. A. Zavitz (At))i. Rpt. 

 Ontario At/r. (i»d Ux/iL I'liioii. ,iT (l!HI')), pp. 12-33). — A (loscrijition of lliese 

 e.\i)erinioiits is ^ivon in coiiiiectioii with proviously reportod rosults ( E. S. K., 

 17. II. liT)!). In tho cooporiitivo cxperinieiits in tlie season of li)05 the loadiuf^ 

 varieties of f,'rain crojjs g.ave tlie following averagi' .yields per acre: Joanette oats, 

 120 tests, .^)8..^),S l)u. ; Mandsoheuri Six-rowed liarley, 28 tests, .37.73 l)u. ; P.I.-iek 

 llulless bitrley, 1.3 tests, 24. (;.''> bn. : Wild Goose spring wheat, 24 tests, ;54.87

 .31:90 bu. ; .Taprtnese buclvwheiit, 7 tests, .37.50 bu. ; Early Britain field i)eas, 10 

 tests, 28..32 bu. : New Prize Winner field beans, 20 tests, 27.21 l»n. ; Early 

 Yellow soy beans, 2 tests, 18.33 bu. ; Dawson Golden Chaff winter wheat. 14 

 tests, 23.1() bu. ; and Conipton Early corn, 17 tests, .5().74 bu. The best and most 

 popular mixture of grains consisted of .34 lbs. of Daubeney oats and 48 lbs. of 

 Mandscheuri barley, which produced on the average in 11 tests 2,073 lbs. of 

 grain per acre. In all cases except one the varieties here mentioned ranked 

 first in popularity with the experimenter.s. .Toanette oats stood second in this 

 I'cgard. 



The leading varieties of field roots and fodder crops gave the following yields 

 I)er acre: Yellow Leviathan mangels, 8 tests, 33.57 tons; Giant White Feeding 

 sugar beets, 7 tests, 35.65 tens ; Sutton Magnum. Bonura swede, 2 tests, 18.04 

 tons; Red Top White Globe fall turnips, 2 tests. .34.53 tons ; Mastodon White 

 Intermediate carrots. 8 tests, 24.-50 tons; Henderson Eureka fodder corn, 7 tests, 

 17.48 tons; .Japanese Panicle millet, 2 tests, 1(>.72 tons, and Dwarf Essex rape, 

 1 test, 17.82 tons. In 3 tests grass peas, connnon vetches, and hairy vetches gave 

 10, 8.93, and 8.05 tons per acre, respectively. Nearly all these varieties were 

 the most popular with the experimenters, excepting Henderson Eureka fodder 

 corn, which was outranked by White Cap Yellow Dent, and grass peas, which 

 ranked next to the vetches. 



Three varieties of sweet corn, Ringleader, Mammoth White Cory, and Golden 

 Bantam, requiring 84, 87, and 88 days, respectively, to mature for table use, 

 were grown in 21 tests. In comparative value Ringleader stood first and in 

 table quality Golden Bantam. The average results for 6 years in 38 tests show 

 that corn in hills gave an average of 11 tons of whole crop as compared with 

 10.10 tons for corn i)lanted in drills. 



In the fertilizer experiments conducted as in previous years, the greatest 

 yield of total crop of corn was secin-ed from the use of nmriate of potash and 

 the greatest yield of Imsked ears from the complete fertilizer. An application 

 of 100 Ibi^. of nuiriate of i>otash per acre increased the yield 1.5 tons at a cost 

 of about .'j;3 per ton for the fertilizer used. The best .yield of swedes, 23.1 tons 

 per acre, was secured where barnyard manure wa;^ applied. In 41 tests 

 during T; years the best average yield of mangels, 26.5 tons per acre, was obtained 

 with nitrate of soda, and during this same period in 74 experiments the highest 

 average yield (jf oats, 48.7 bu. per acre, was secured with the complete fertilizer. 



In 1905 the average yields of 3 late vr.rieties of potatoes, Denlpsey Seedling, 

 Empire State, and American Wonder, grown in 93 tests, were, respectively, 

 177.1. 160.3, .ind 1.59.4 bu. per acre. Of 2 medium varieties grown in 70 tests, 

 I{oso of the North stood first with 184 bu. i)er acre, while among early' varieties 

 in 1.58 tests Early Fortune headed the list with 107.4 bu. Dempsey Seedling, 

 Rose of the North, and Early Fortune ranked first in jiopularity in their 

 resi)ective classes. The aver.-ige results of 33 tests for 5 years show n slight 

 advantage in growing potatoes on ridges as compared with growing them on 

 the level.
