 plats. Theeoiii|>lete fertilizer ai)])lieat ion, containing suiJerphosphatiM if lime, yielded 

 the largest (jnantity of green crop of broine grass, Imt the check i>lat, producing over 



1 toil of green crop less ])er acre, gave the highest yield of hay. In a test at the farm 

 for the Maritime Trovinces an application of muriate of jiotasli gave better results 

 than nitrate of soda and superphosphate, applied singly or in combination with the 

 muriate. The results of special fertilizer experiments at this farm with l)arnyard 

 manure and c(jmj)lete conmiei-cial tV-rtilizers on different crops and crop mixtures are 

 tabulated without comment. At the Manitoba farm, in a te.st with spring wheat, a 

 mixture of 200 lbs. superphosphate, 100 lbs. nitrate of soda, and 100 lbs. muriate of 

 potash i)er acre, one-half api)lied before sowing and the rest when the grain was 



2 or ;5 in. liigh, gave the highest yield of straw and grain — 3,840 lbs. and 88 bu. per 

 acre, respectively. In a test in the Northwest Territories the yield of wheat, and at 

 the British Columbia farm the yield of oats, was also in favor of this combination and 

 method of application. 



The yields of different root crojis and vegetables grown in various coml)inati(nis at 

 Ottawa are given in a table. Shallow cultivation and management of soils is dis- 

 cussed by the agriculturist of the Ottawa farm, and a series of crop rotations are 

 recommended. The itemized cost of growing oats, mixed crops, hay, corn, mangels, 

 turnips, sugar beets, and pumpkins is reported. The yields of hay obtained from 

 different mixtures of grasses and clovers are shown and a number of important 

 sj)eeies of grasses are described. The best yield of hay this year was obtained from 

 a mixture of meadow fescue 6 lbs.,, orchard grass 2 lbs., Kentucky blue grass 1 lb., com- 

 mon red clover 4 lbs., alfalfa 3 lbs., and white Dutch clover 1 IVj. The first cutting, 

 July 10, yielded 2.6 tons of hay, and the second cutting, August 30, 3.16 tons. 

 Austrian brome grass compared with timothy and a mixture of alfalfa and broine 

 grass at the Manitoba farm led in the yield of hay. The results for 3 years of a plan 

 of crop rotation followed at the farm for the Northwest Territories are summarized. 

 Brief notes are given on the growth of various forage crops at the different farms. 



Cooperative experiments in agriculture, C. A. Zavitz {(Jnlario Ayr. and Kept. 

 Lhiioit Ilpt. 1902, pp. W-J4) • — The average results of cooperative variety tests carried 

 on by the Ontario Agricultural and Experimental X'nion in 1902 with oats, barley, 

 v/heat, 1)nckwheat, peas, soy beans, corn, mangels, sugar beets, swedes, kohl-rabi, 

 turnips, jiarsnips, carrots, millet, sorghum, vetch, rape, kale, clover, grasses, and 

 other forage crops are reported in tables and briefly discussed. 



The leading varieties were Oderbrucker oats, Oder]>rucker Six-rowed barley, Black 

 Hulless barley, Japanese buckw^heat. Early Britain pea, Medium Green soy bean, 

 Compton Early corn, Dawson Golden Chaff winter wheat, Evans Improved mangel, 

 New Danish Improved sugar beet, Sutton Magnum Bonum swede, Greystone and 

 Early White Vienna kohl-rabi, Bruce Mammoth Intermediate "carrot, Improved 

 Half Long parsnip, Wisconsin Earliest White Dent fodder corn, Japanese millet. 

 Early Amber sorghum, hairy vetch. Dwarf Essex rape, Thousand Headed kale, 

 ]Mammoth red clover, and tall oat grass. Alfalfa gave a larger crop than sainfoin 

 and ])urnet. 



In a cooperative test fertilizers w;ere applied singly and in combination. Nitrate 

 of soda and muriate of potash were each used at the rate of 160 lbs. per acre, and 

 superphosphate at the rate of 320 lbs. The mixed fertilizer consisting of one part 

 of nitrate of soda, one part of muriate of potash, and two parts of superphosphate 

 was applied at the rate of 213.3 lbs. per acre. The average results for the number of 

 years the work has been in progress show that the greatest yields were produced by 

 the mixed fertilizer with oats, turnips, and corn for grain; l)y nitrate of soda with 

 mangels, and l)y muriate of j)otash with corn for fodder. The fertilizer apparently 

 exerted a greater influence on mangels and swedes than on either corn or oats.
