 All 4 varieties were over the standard in weiglit. The varieties giving the 

 liighest weight per measured bushel in 190(i were Northwester. Geneva. McPher- 

 .son. Economy, and AuV)urn, but most of tliese excei)ting Auburn were rather low- 

 in yield. In general tlu^ white wheats yield more grain. ]»ossess stronger straw, 

 weigh a little less per measured bushel, and are slightly softer in the grain

 l)rogress since 1892 at this station, together with the plats on which the work 

 was carried on. is described, and the results for the year 190(> are reportetl in 

 tables and discussed. 



Forty-five varieties of wheat were grown in 19(t(). With the exception of 1 

 variety there was only ?> days" difference between the maturity of the earliest 

 and latest sorts. No. 1718. a new selection from the breeding nursery, was 

 grown for the first time, and the fact that it lodged less than the rest, the straw 

 being stifter, is taken as showing the results of careful selection in the nursery. 

 The varieties of-difterent classes of wheat giving the highest average yields for 

 4 years were as follows : Blue stem. Select Blue Stem. 28.9 bu. : fife, Select Pow- 

 ers, 2G.8 bu. ; and durum, Black Don, .31.7 l>u. pc^r acre. Fourteen out of the 

 1.") varieties of fife and blue stem giving the highest yields in 1*.X)6 came from the 

 |)lant nui'sery of the station, and when the averages for 8 years are considered. 

 '.• (tut of the 10 varieties giving the highest yields came from this nursery. The 

 .average for 7 years gives the durum wheats an advantage of 4.47 bu. per acre, as 

 compared with the fife and bhie stem varieties. 



The following varieties of durum Avheat have given the best results in the 

 station trials and are recommended for North Dakota : Gharnovka U. S. No. 

 .">«Ut;, Yellow (iharnovka U. S. No. 5642, Arouautka, Black Don U. S. No. 564r). 

 Kubanka U. S. No. .jt)39, and Velvet Don U. S. No. oG44. The average yields of 

 rliese varieties varied from 29.4 to 31.1 bu. per acre. 



Fertilizer tests with wheat were made on land cropped for 20 years without 

 fertilizing. The years 1903 to 190."), inclusive, showed a maximum increase in 

 yield of 2.3 bu. of wheat per acre as a])i)arently due to the applications. The 

 most effective conunercial fertilizer application gave only i bu. greater yield of 

 wheat per acre than the use of well-rotted stable manure. 



Different methods of soil preparation showed that spring disked corn ground 

 gave as an average for 3 years 1.4 bu. more per acre than fall plowing. Fall 

 Itlowed land gave 2.0 bu. more than spring plowing. 



Wheat was drilled at the rate of 5 pk. per acre and 2 lbs. of rape was sown in 

 addition. The rai)e did not interfere with harvesting, but sometimes delayed 

 the curing of the Inuidles. The rape plants were strong and healthy, and when 

 the wheat was cut and conditions were favorable a lai-ge ([uantity of good 

 fall jiasturage was produced. 



The average comparative yields of different grains for 8 years were as fol- 

 lows: Oats 1.9()9 lbs., emnier 1,94.") lbs., liarley 1,877 lbs., durum wheat 1.83." 

 llis., and wheat 1,711 lbs, of grain per acre, of 28 varieties of oats grown in
