FIELD CROPS. 325 



the highest yield was producod by Ontario Cliauipion, reaching IS tons and 

 1,752 lbs. The highest yielding variety of sngar beets was Vilmorin Im- 

 proved, which gave a yield of 13 tons and 400 lbs. from early sowing and 12 

 tons and 2SS lbs. from late sowing. 



At Agassiz the leading variety of ensilage corn of 19 varieties tested was 

 Eureka, which produced 22 tons and 220 lbs. grown in rows and 21 tons and 900 

 lbs. grown in hills. In the distance experiments with corn at this station the 

 corn was al.so grown in rows and in hills. The best yield in rows, IS tons and 

 (5S(i lbs., was produced by Champion White Pearl iu rows 42 in. apart. Cham- 

 pion White Pearl also stood first in yield of 18 tons per acre when grown iu 

 hills at a distance of 42 in. between the rows. Turnips, mangels, carrots, and 

 sugar beets were sown on two different plats about 2 weeks apart iu the early 

 part of May. The highest yield in the experiment with turnips on the early 

 sown plats was produced by Jumbo, and amounted to 18 tons and 1,752 lbs. On 

 the late sown plats Mammoth Clyde ranked first with 16 tons and 76 lbs. Half 

 Sugar White produced 25 tons and 160 lbs., being the highest yield for the 

 early sown mangels, and Giant Yellow Intermediate yielded 20 tons and 1,844 

 lbs., which was the highest yield for the late sown plats. Ontario Champion 

 among 6 varieties of early sown carrots produced 39 tons and 1,936 lbs., and 

 also ranked first among the late sown carrots with 38 tons and 32 lbs. Vilmorin 

 Improved among 3 varieties of sugar beets ranked first in botli early and late 

 sowings. 



In 1907 the best yields from the special fertilizer experiments with wheat 

 now in progress for 20 years were secured on plats 1 and 2 treated with 15 tons 

 per acre of barnyard manure. Plat 6, which ranked first iu 1906, stood second 

 this year. In average yield for the 20 years the barnyard manure plats also 

 stood first. In the tests with barley, plat 2 stood first with 38 bu. and 16 lbs. 

 per acre, and this plat also heads the list iu average yield for the entire period. 

 In the tests with oats plat 1 ranked first with 64 bu. and 4 lbs. in 1907, and 

 plat 2 ranked first in average yield for the entire 19 years with 55 bu. and 25 

 lbs. Plat 1 produced the highest yield of ensilage corn, 12 tons and 1,110 lbs. 

 per acre in 1907. This plat also ranks first in average yield for 16 years with 

 16 tons and 272 lbs. Plats 1 and 2 also gave the best results for the year as 

 well as the best average results with turnips and mangels. 



Notes on the pi-ogress and the results of other fertilizer tests as well as i-ota- 

 tiou experiments and vitality tests are given. 



Experimental work in fi.eld Tiusbandry, C. A. Zavitz (Ann. Rpt. Ontario 

 Affi: Col. and Expt. Farm, 3', (lOOS), piK 172-182, lS.',-2.iO, figs. J3).— Experi- 

 mental work carried on by the college, and the weather conditions prevailing 

 during the season are described, and statistics on crop production in the prov- 

 ince, including average yields of the different crops for 25 and 26 years are 

 presented. Earlier reports have been previously noted ( E. S. K., 19, p. 1130). 



In 2 experiments made to determine the relative production of the principal 

 grain crops, 1 in progress for 6 and the other for 2 years, it was shown that in 

 both instances emmer jiroduced the largest yield, followed in the order men- 

 tioned by barley, oats, huUess barley, and Wild Goose spring wheat. In the 

 6-year experiment common emmer produced 2.756 lbs., Mandscheuri barley 

 2,715 lbs., Joanette oats 2,559 lbs., and Black Hulless barley 2,527 lbs. of grain 

 per acre. In the 2-year experiment the yields were a little larger. In the first 

 experiment. Wild Goose wheat and flax produced the stiffest straw, and in the 

 second. Wild Goose wheat and Dakota Mammoth spring rye. 



The difference in productiveness of varieties is shown in a table. The aver- 

 age yields of Joanette. Siberian, Egyptian, and Rlack Tartarian oats grown for 

 19 years was 87.7, 87.3, 75.6, and 71.8 bu. per acre, respectively. The average
