936 EXPERIMENT STATION RECORD. 



The results on the uniform test plats in 1906 show that among 37 varieties of 

 spring wheat, Bishop, Ebert Selected, and Colorado headed the list in pro- 

 ductiveness with yields of 41 bu. 40 lbs., 40 bu. 20 lbs., and 40 bu. per acre, re- 

 spectively. Of the list of varieties entering into this test, 23 represented va- 

 rieties and selected strains produced at the Central experimental farm, Ottawa. 

 Aurora and Ebert Selected were the earliest of the most productive sorts, 

 ripening August 1 and 2, respectively. Among 12 Aarieties of durum wheat 

 under test Roumanian headed the list this year with 41 bu. per acre. This 

 variety has also given the largest average yield during the past 5 years. AVin- 

 ter wheat was sown August 29, 190'), but only one variety, Padi, proved satis- 

 factory. This variety ripened on July 23 and yielded at the rate of 40 bu. 40 

 lbs. per acre. 



At the Nova Scotia farm at Xappan IG varieties of spring wheat were com- 

 pared this year and the leading varieties were Red Fern, Red Fife, Bishop, and 

 White Fife, the yields being 34 bu., 33 bu. 20 lbs., 32 bu. 40 lbs., and 32 bu. per 

 acre, respectively. At this farm Goose durum wheat yielded per acre 22 bu. 40 

 lbs., while Roumanian yielded 22 bu. 



At Brandon, where 16 varieties of spring wheat were tested, Preston stood 

 first in yield r)er acre with 44 bu., followed by Huron with 43 bu. 50 lbs., Pringle 

 Champlain with 41 bu. 50 lbs., and Red Fife with 40 bu. per acre. Among 4 

 varieties of durum wheat, Goose was the leader with 56 bu. 20 lbs. per acre. 



The results of a fertilizer test show that the plat receiving 200 lbs. per acre 

 of muriate of potash, spread just before sowing the wheat, produced 39 bu. 20 

 lbs. per acre, this being the highest yield in the series, while the plat receiving 

 no fertilizer produced 32 bu. 40 lbs. The use of 200 lbs. per acre of nitrate of 

 soda, half applied when the grain was 2 in. high and the rest when it was 6 in. 

 high, was apparently without effect. Smutty seed wheat treated with formalin 

 and bluestone produced yields ranging from 31 bu. 10 lbs. to 34 bu., while the 

 same kind of wheat not treated yielded 19 bu. 30 lbs. 



On the Saskatchewan farm at Indian Head the most productive among 22 

 varieties of spring wheat were White Fife, Preston, and Stanley, the yields 

 being 48 bu. 40 lbs. 46 bu., and 45 bu. 20 lbs., respectively. Of the varieties 

 compared 15 yielded 41 bu. per acre or more. In a fertilizer test the plat re- 

 ceiving 2(X) lbs. of muriate of potash per acre ranked first in yield with 48 bu. 

 40 lbs., the unfertilized plat producing 35 bu. 20 lbs. per aci'e. Among the 

 durum wheats, Yellow Gharnovka stood first with 52 bu. 40 lbs. per acre, fol- 

 lowed by Goose with 1 bu. less. 



Spelt and emmer. — At the Central experimental farm, the yields of 11 

 varieties of emmer and spelt ranged from 600 to 2,720 lbs. per acre. The 

 best yielding varieties were Common, Red, and Double emmer, the Red and 

 Double producing 2,680 and 2,540 lbs. of grain per acre, respectively. Two 

 varieties of spelt and two of emmer were grown at Nappan. White and Red 

 spelt led in yield with 2,120 and 1,880 lbs. per acre, respectivelj . Common 

 emmer and Red spelt produced the best results at Brandon, the yields per acre, 

 respectively, being 3,820 and 3,180 lbs. At Indian Head, Red spelt produced 

 3,600 lbs. per acre and Common emmer 3,220 lbs. per acre, these two being the 

 best yielding among 5 varieties. 



Oats. — The results of experiments with fertilizers on plats of oats at the 

 Central experimental farm show that the best average yields for 18 years 

 were secured on the barnyard manure plats, the one receiving the fresh manure 

 yielding 56 bu. per acre, and the one receiving the well-rotted manure yield- 

 ing 52 bu. 11 lbs. per acre. The fresh manure plat also ranked first in 1900 

 with 53 bu. 8 lbs., while the well-rotted manure plat stood third, having pro-
