Change of seed is wrong in principle and very dangerous in practice. A 



good rule is never to change your seed unless you are sure that the new seed is better 

 than the old, and that it is perfectly free from weed seeds. It is generally much wiser 

 to clean and grade up one's own seed than to make any change — unless a new and 

 superior variety is being received. 



WHAT VARIETIES SHALL I SOW IN 1916? 



Results of 4,000 Experiments in Ontario, as established by the 

 Experimental Union 



Oats 



Of all varieties grown in Ontario to-day, the O.A.C. No. 72 is the most outstanding 

 variety. It is the heaviest yielder, has the stiffest straw and the grain has only 27% 

 of hull. It is also very resistant to smut. Comparing it with the Banner, which is 

 the most widely grown Oat in this Province, we see that over a period of nine years 

 the average yield of the O.A.C. No. 72 was 90.6, while that of the Banner was only 

 72.5 bushels per acre. 



Another Oat that is coming into prominence is the O.A.C. No. 3. It is a very 

 early Oat and therefore is quite suitable for sowing with Barley where a grain mixture 

 is desired. 



Barley 



In the experiments conducted at the College the O.A.C. No. 21 Barley still leads. 

 It is even better than the Mandscheuri variety, introduced by the College 26 years ago. 

 It is now estimated that 96% of all Barley grown in Ontario belongs either to the 

 O.A.C. No. 21 or Mandscheuri varieties. It is worthy of note that of the 40 entries 

 of Barley at the Winter Fair, O.A.C. No. 21 was the only variety exhibited. 



According to the reports of the Bureau of Industries, the yield of Barley per acre 

 for the past 16 years has increased twenty-three per cent. This has undoubtedly 

 been due to the introduction of superior varieties. It is estimated that the value of 

 this increase is approximately $3,50i,,000. 



Spring Wheat 



The past year has seen an increase in the production of spring wheats, due of course 

 to conditions in Europe which have brought about an increase in the price of wheat. 

 Of the two varieties sent out to experimenters last year, the Wild Goose variety gave the 

 highest yield, 19.9 bushels per acre. However, Marquis yielded 19.2 bushels and has 

 much better milling qualities. 



Mixed Grains 



The average results of experiments conducted over a period of five years show that 

 a mixture of one bushel of barley and one bushel of oats give the highest yield. This is 

 sown at the rate of two bushels per acre. For two years, during which the growing 

 season was rather dry, a heavier seeding gave better yields. In each year the poorest 

 yield resulted from the thinnest seeding. 



Roots 



In Mangolds, Sutton's Mammoth Long Red gave a slightly higher yield than the 

 Yellow Leviathan. However, taking the result of experiments over a number of years, 

 the Yellow Leviathan has given higher yields and is the most popular mangold in 

 Ontario to-day.
