132 EXPERIMENT STATION EECORD. 



Potatoes. — At Ottawa the best average results were obtained by iilanting the sets 

 14 in. apart in the row, as compared with 10, 16, and 18 in., the average results at 

 12 in. being nearly as good. Planting 1 in. deep gave the best results, but a depth 

 of 4 in. is recommended to prevent the sets being disturbed by cultivation. Plant- 

 ing on May 30 gave better yields for both early and late varieties than later planting, 

 and the average yields for 4 successive years are also in favor of planting the latter 

 part of May. Spraying with Bordeaux mixture for the prevention of blight and rot 

 proved profitable. Special experiments with fertilizers in the Maritime Provinces 

 showed that manure increased the yield of potatoes to a larger extent than other fer- 

 tilizers. A test of 8 early varieties is also reported from this farm. 



Millets. — At Ottawa Cat-tail, Pearl, White Round Extra French, and Moha Hun- 

 garian, in the order named, produced the heaviest crops among 9 varieties, the yields 

 of hay ranging from 5 tons and 240 lbs. to 8 tons and 1,280 lbs. per acre. Oh the 

 Manitoba farm Japanese millet yielded 3 tons and 1,400 lbs. and Common 2 tons 

 and 1,760 lbs. of hay per acre; and in the Northwest Territories Italian, Cat-tail, 

 Hungarian, and Japanese gave better yields than White Round Extra French, Ger- 

 man, or Pearl. 



Soy beans — Horse beans. — These crops at Ottawa produced the best yield in the 

 28-in. rows, while in the Northwest Territories the yield of soy beans was in favor 

 of the 21-in. rows, and of horse beans the 35-in. rows. 



Tobacco. — Plat tests of 46 varieties were made at Ottawa. Of 6 varieties grown on 

 large areas, Connecticut Seed Leaf gave the largest yield, 2,192 lbs. of dry leaves j^er 

 acre. 



Bticl-wheat. — Of 5 varieties tested in the Maritime Provinces, Silver Hull yielded 

 the most grain and straw, and in a field test produced 84 bu. on 5 acres. At the 

 Manitoba farm volunteer crops of Japanese, Silver Hull, and Gray produced over 28, 

 32, and 35 bu. per acre, respectively. 



Flax. — Growing flax and wheat in a mixture has been mentioned above under 

 wheat. Sowing 40 lbs. of flax per acre in Manitoba gave the best total yield, as 

 compared with sowing 30 or 20 lbs. per acre. In the Northwest Territories flax was 

 sown at the rate of 40 and 80 lbs. per acre on May 15, 22, and 29. For the earliest 

 date the yield of seed was in favor of the lighter seeding, but for the other dates the 

 yield was in favor of the heavier seeding. The difference in yield varied from 1 bu. 

 and 26 lbs. to 2 bu. per acre. White flax was tested, but the straw did not grow 

 over 6 in. high, and very little seed formed, although the season was very favorable 

 for ordinary flax. 



Spelt. — This grain was compared with wheat, oats, and barley in Manitoba, the 

 yield of grain being largely in its favor. The heaviest crop was obtained from drill- 

 ing at the rate of 1| bu. per acre, the yield being 46 bu. Summer fallow produced a 

 larger crop of spelt than unplowed stubble land. In the Northwest Territories a 

 yield of 58 bu. and 20 lbs. per acre was obtained. 



Sunflowers. — One and one-half tons of heads per acre were obtained from ]\Iammoth 

 Russian sunflowers at the Manitoba farm, while in the Northwest Territories this 

 variety sown May 22 was frozen September 17 and did not mature. 



Rape. — The results of growing rape and wheat in a mixture have been given above 

 under wheat. In the Northwest Territories Dwarf Essex, Broad Leafed, and Dwarf 

 Victoria yielded over 41, 41, and 31 tons per acre, respectivel}»! In British Columbia 

 Dwarf Essex was a failure. 



Miscellaneous. — A num]:)er of experiments in addition to those already mentioned are 

 reported by the Central farm. In a test with mixed roots and mixed roots and vegeta- 

 bles the largest yield was obtained from a mixture of mangels, carrots, and turnips, and 

 the smallest yield from a mixture of carrots, cabbages, and tomatoes. A report on the 

 influence of previous crops on growing grain shows that oats and barley gave the 

 best yield after horse beans, as compared with flax, grain, and soy beans. Clover aa
