 fallow, wheat, wheat, suninier fallow, corn, barley (seeded down with western 

 rye grass and alfalfa), hay, and pasture $s..32 ; and of a 9-year rotation of 

 summer fallow, roots, wheat, oats, summer fallow, wheat, oats (seeded down 

 with western rye grass and alfalfa), hay, and pasture $9.12. 



In regard to a 3-, 6-, 8-, and 9-year rotation at llosthern, Saskatchewan, it 

 is noted that " land worlied under a rotation including grains and hay gives a 

 greater profit per acre than where wheat alone is grown, and this is empha- 

 sized in a season of early frosts; that a hoed crop in the rotation inci'eases the 

 cost of operation per acre, but very much more increases the profit per acre 

 as well as the yield of the succeeding grain crops." 



In studying the relative value of summer fallow manured, summer fallow 

 without manure, green crops of peas, and vetches plowed under it is noted that 

 the plowing under of a green crop evidently left the ground too dry for any 

 great benefit to be derived by the crop of the succeeding year, but showed an 

 advantage over bare fallow in the second succeeding crop. 



The yields of hay in 1913 at Scott, Saskatchewan, as results of various 

 methods of seeding 10 lbs. each of western rye grass and red clover seed per 

 acre, are given as follows: With wheat after summer fallow, 2 tons 400 lbs.; 

 alone after summer fallow, 2 tons 1.200 lbs. ; with wheat after roots, 2 tons 

 800 lbs. ; alone after roots, 2 tons 680 lbs. ; with wheat after wheat, 1 ton 

 1.240 lbs.; alone after wheat, 1 ton 1,160 lbs.; with oats after wheat, 1,720 

 lbs. ; alone after wheat on manured land, 1 ton 80 lbs. ; with wheat after 

 two successive crops of wheat, 1 ton 820 lbs. ; alone after oats jireceded by 

 wheat, 1 ton 400 lbs. ; with wheat after wheat preceded by a hoed crop, 1 ton 

 1,860 lbs. 



In regard to the experimental work at Lethbridge, Alberta, it is noted that 

 " on the dry land the yields of hay were very light. Brome grass produced 

 only 1,580 lbs., and western rye grass 1,160 lbs. per acre. Alfalfa sown broad- 

 cast yielded only 1,481 lbs. per acre whereas alfalfa sown in rows yielded about 

 double this amount. . . . 



"Wheat following corn yielded as well as wheat after summer fallow, and 

 much better than wheat following turnips. The latter difference is no doubt 

 due to the fact that the roots made considerable growth in the fall, thereby 

 using up moisture, whereas the corn ceased growth with the first frost. A gootl 

 profit was obtained from alfalfa seed when the crop was planted in rows and 

 intertilled. Heavy yields of oats and peas, grown for feed, were obtained when 

 sown on summer fallow. With irrigation, the yield of spring wheat was over 

 52 bu. per acre, following potatoes. With irrigation, iwtatoes planted on alfalfa 

 sod gave a yield of 635 bu. 30 lbs. per acre. . . . 



" Our results to date indicate the following rates of seed per acre to be 

 the best: Winter wheat, nonirrigated, 60 lbs.; spring wheat, nonirrigated, 75 

 lbs. ; oats, nonirrigated, 60 to 75 lbs. ; barley, nonirrigated, 75 to 90 lbs. ; spring 

 wheat, irrigated, 90 to 105 lbs. ; and oats, irrigated. 75 to 90 lbs." 



At Lacombe, Alberta, trials of graded seed showed that " wheat fanned three 

 times, under strong wind, yielded 35 bu. 11 lbs. per acre, wheat fanned once 

 yielded 26 bu. 50 lbs., and wheat not fanned, 24 bu. . . . 



"The deep working of the land in the summer fallow year did not appear 

 to give any special results on the first succeeding crop (wheat) but influencetl 

 favorably the second crop (oats). In the breaking out of sod, plowing at a 

 depth of 5 in. gave better results than at 3 or 4 in. This practice also proved 

 superior, this year, to breaking sod 3 in. and plowing the wheat stubble G in. 

 for the following oat crop."
