inclusive, than for the 23 years, and the yields obtained in cooperative experiments 

 during these 3 years are much higher than the general results for the province. The 

 following results were obtained at the college in comparing the yields of field crops 

 grown under similar conditions:

Four six-rowed varieties of barley, Mandscheuri, Common srx-rowed, Oderbrucker, 

 and Mensury, grown for 15 years, have given an average yield of 71.4, 62.4, 64.4, and 

 60 bu. per acre, respectively. For the last 5 years the corresponding yields were 

 73.5, 68.7, 68, and 63.1 bu. Of 6 two-rowed varieties the average yields for 11 

 years were in favor of Two-rowed Canadian, Xew Zealand. Chevalier, Jarman 

 Selected Beardless, and French Chevalier. Two-rowed Canadian and Selected Cana- 

 dian Thorpe gave the best yields of 17 varieties in 1904. The average yields of hul- 

 less barley for 5 successive years are as follows: Guy Mayle 54.4 bu., Black Hulless 

 51.5, Hungarian 50.2, Purple 49.2. and Winnepeg Xo. 2, 46.9 bu. The clover and 

 alfalfa preceding barley in the rotation produced a much larger increase in crop than 

 the grasses, there being a difference of nearly 12 bu. per acre between red clover sod 

 and timothy sod. In 8 out of 12 years winter barley survived the winter and gave 

 an average yield of 64.1 bu. 



Joanette, Siberian, Waterloo, Oderbrucker, Probsteier, Bavarian, Egyptian, and 

 Black Tartarian oats, mentioned in the decreasing order of yield, have been grown 

 for 15 years in succession without change of seed and with average yields ranging 

 from 71.1 to 90.5 bu. per acre. Of 78 varieties the following produced the greatest 

 yield of grain in 1904: American Banner, Peerless, New Zealand, Irish Victor, Mich- 

 igan Wonder, German Rust Proof, Black Gotham, Liberty, and The Great American. 

 In weight of grain only Early Dawson, White Superii >r Scotch, Zhelannie, and Tobolsk 

 weighed as high as 40 lbs. per measured bushel. 



Seed selection has now been in progress for 12 successive years, and in 1904 the 

 large plump seed produced 94.1 bu., the light seed 68 bu., and the hulled seed 91.6 

 bu. per acre. In the crop from the large and the light seed 1,390 and 2,095 grains, 

 respectively, weighed an ounce. In using smutted oats 1, 2, 3, and 4 years old for 

 seed it was found that as the seed increased in age the yield of oats decreased and 

 the percentage of smutted heads increased. Timothy and clover sown with oats 

 exerted but a very slight influence upon the yield. Winter oats have never been a 

 success at the college. 



The average weight per bushel and the average yield of the most productive varie- 

 ties of winter wheat for the past 5 years, including 1904, were as follows: Dawson 

 Golden Chaff 59.9 lbs. 59.8 bu., Imperial Amber 61.2 lbs. 58 bu., Prize Taker 59.8 

 lbs. 57.6 bu., Silver Dollar 59.7 lbs. 57 bu., Buda Pesth 61.4 lbs. 55.4 bu., Rudy 61.1 

 lbs. 55.4 bu.. Forty-fold 59.1 lbs. 55.4 bu., and Egyptian Amber 61.4 lbs. 55.2 bu. 

 In 1904 Dawson Golden Chaff possessed the strongest, and Red Hussar the weakest 

 straw, and Ironclad, Tasmania Red, and Pride of America were freest from rust.
