FIELD CROPS. 223 



$5.50 to $9.62 per year, the .most profitable being a 3-year rotation in which 

 the first year from 12 to 15 tons of barnyard manure per acre is applied in 

 winter, the soil plowed about 5 in. deep, and planted to corn; the second year 

 oats, then seeded down to 10 lbs. red clover, 2 lbs. alsike clover, 6 lbs. alfalfa, 

 and 6 lbs. timothy per acre; and the third year clover hay. 



Results of germination tests of about 1,000 samples of wheat, barley, oats, 

 and peas grown on the various farms are given. The maize when planted for 

 silage, produced an average of 13 tons 1,668 lbs. per acre when planted in rows, 

 and 15 tons 1,66S lbs. when planted in hills. From the analysis of broom corn 

 it is suggested that when grown for broom manufacturing, this plant may be 

 used as a by-product in the feeding of stocJj. 



In a report of sugar-beet tests in various parts of the Dominion, the per- 

 centage of sugar in the juice varied from 11.72 to 18.7 per cent, and the yield of 

 roots per acre from 3 tons 1,594 lbs. to 24 tons 1,104 lbs. in 1911. It is con- 

 cluded that beets of excellent quality may be produced in many widely separated 

 districts throughout Canada, 



In an experiment with lime on swamp land on Prince Edward Island, In 

 which applications of 5, 10, and 20 bbls. per acre were compared with no lime, 

 buckwheat, barley, oats, rye, and wheat were used. In each case, except with 

 the wheat, the best yields were obtained with the largest application of lime. 

 With potatoes, omitting lime on the freshly cut sets was followefl by a de- 

 creased yield of, on an average,. 31 bu. 47 lbs. per acre with 15 varieties, and an 

 increase of 26 bu. 34 lbs. per acre with 6 varieties. 



In cultural experiments with com at the Central Quebec farm, the yield per 

 acre when drilled 8 in. between plants and 42 in. between rows was 13.89 tons 

 as compared with 13.82 tons when 48 in. between rows. In 42 in. checks the 

 yield was 11.92 tons and in 36 in. checks 11.33 tons. 



In variety tests the amount of digestible protein produced per acre from the 

 highest yielding varieties of winter peas was calculated to be 549.1G lbs., oats 

 308.16 lbs., mixed oats and barley 218.28 lbs., wheat 205.92 lbs., 2-rowed barley 

 166.32 lbs., and 6-rowed barley 146.16 lbs. 



The results at the Manitoba farm in using grades of wheat from No. 1 hard 

 to Nos. 1 and 6 Northern, and feed wheat showed yields ranging from 29 bu. 

 per acre with the feed wheat to 39 bu. with the better grades. The results of 

 a treatment of wheat seed to prevent smut are summarized in tabular form. 

 Untreated seed showed 161 smutty heads per thousand, and a yield of 44 bu. 

 40 lbs. per acre. A higher yield, 48 bu. 40 lbs., was obtained with seed im- 

 mersed in formalin, 1 lb. to 40 gal. of water, than in sprinkling or immei.?ing 

 in stronger solutions or treatment with biuestone. 



Slightly larger yields of wheat followed the use of 2 bu. of seed per acre 

 than with smaller quantities, but results with oats and barley were incon- 

 clusive. Seeding both wheat and oats to the depth of 2 in. gave better yields 

 than 1, 3, or 4 in. The results of a soil packing experiment are summarized as 

 follows: Unpacked 45 bu. 25 lbs. per acre; surface packer before seeding 51 

 bu. ; combination packer after seeding .50 bu. 20 lbs. ; subsurface packer before 

 seeding 53 bu. 40 lbs. ; surface packer after seeding 53 bu. 40 lbs. ; combination 

 packer after seeding 55 bu. ; sut)snrface packer after seeding 54 bu. 40 lbs. ; 

 surface packer and harrow after seeding 54 bu. ; combination packer and harrow 

 after seeding 55 bu. ; subsurface packer and harrow after seeding 54 bu. 40 lbs. ; 

 surface packer before and after seeding 53 bu. ; combination packer before and 

 after seeding 52 bu., and subsurface packer before and after seeding 55 bu. 

 20 lbs.
