So l)ks. of t-et'd per acre gave the best yield, l)ut the average yields for 4 years are iii 

 favor of () and 7 pks. of seed i)er acre. 



Experiments in plowing for wheat begun in previous years were continued. As 

 indicated by the average results fall plowing gave better yields than spring plowing. 

 In some seasons spring plowing gave the best returns. For 5 years, including the 

 season of 1901, fall plowing from 3 to 4 in. deep was compared with |)lowing from 6 

 to 7 in. deep. The results were in favor of deep plowing, but the difference in the 

 average yields was only 0.6 of a bushel per acre. The outcome of a similar experi- 

 ment carried on for 3 years with spring plowing also favored the deeper plowing, the 

 difference in the average yields per aci'e in this case being 0.9 of a bushel. A com- 

 parison for 4 years of disk and moldboard plowing either in the fall or spring gave 

 results in favor of the moldboard plowing. Trials with different makes of disk plows 

 are reporte<l in this connection. 



Oa/.s. — Of 26 varieties grown in 1901, ^Minnesota No. 202, Silver Mine, Early Goth- 

 land, Si))erian White, and Bow of Promise, given in the order of i)roductiveness, 

 were the leading sorts. The yield of Minnesota No. 202, tested at this station for the 

 first time, was 67.1 bu. per acre, while the jdeld of the other 4 varieties ranged from 

 60.3 to 60.9 bu. Early (Gothland, which has proved a good yielder, and Siberian 

 White and Bow of Promise produced a grain of fine ajjpearance and quality. 



Barley. — Fifteen varieties were grown this season. The best yielding varieties 

 were Mandscheuri, INlanshury, Minnesota No. 87, Minnesota No. 105, and JNIinnesota 

 No. 32, producing 45.1, 42.1, 40.4, 40.3, and 40 bu. per acre, respectively. Mand- 

 scheuri and Manshury barley are considered identical. In trials carried on for 8 years, 

 Manshury 6-rowed barley has jjroved to be one of the best yielding varieties. 



Emmer. — Emmer from Dakota-grown seed yielded 48.7 bu. jier acre, and from seed 

 obtained from this Department 56 Ini. A history of this grain is given, reference is 

 made to its being erroneously called spelt, and its yielding capa^^ity and feeding value 

 are compared with barley, oats, and wheat. 



Flux. — In growing flax for comparison it was estimated that the crop of common 

 flax was at least one-fourth better than Argentine flax. The thinnest seeding, IJ 

 pks. per acre, produced the largest crop of seed and straw. 



Potatoes. — A field trial of 21 varieties was conducted. The leading varieties were 

 Sunlight, •Daughter of Rose, IMillion Dollar, Rose of the North, and Mark Ilanna, 

 yielding 207.'5, 199.2, 181.1, 174.2, and 171.6 bu. jier acre, respectively. Early Andes 

 and Rural New Yorker No. 2 have been grown at the station for several years and 

 improved by selection. The results, with descriptive notes on all the varieties 

 grown, are tabulated. 



Brome grass. — A series of l:>rief reports on the value of brome grass from farmers 

 throughout the State is given, and the culture of brome grass discussed. 



Results at the Edgeley suhstation. — A description of the station and its organization is 

 given, and the results" obtained in 1901 are briefly reported. Shallow plowing for 

 wheat yielded 55 per cent more than deep plowing. A test of Aronautka macaroni 

 wheat resulted in a yield of 9 bu. per acre. Harrowing wheat 3 times after it had 

 begun its growth resulted in a failure of the crop. Culture tests with emmer, oats, 

 flax, corn, millet, Kafir corn, Canadian field peas, Japanese barnyard grass, l)rome 

 grass, Turkestan alfalfa, rape, potatoes, sugar beets, and artichokes are briefly 

 recorded. A study of the distribution of the roots of corn between two hills 3| ft. 

 apart showed that some of the roots had attained a length of 5 ft., extending from 

 hill to hill and from 2 to 3 ft. into the soil. 



Report of the botanist, H. L. Bolley {North Dakota Sta. Rpt. 1901, pp. SO-44). — 

 Wheat. — These experiments are in continuation of work in progress for 4 years and 

 previously described (E. S. R., 13, p. 345). This season the results of tests in the 

 selection of wheat from the individual heads were inconclusive. The general results 

 of the tests for the 4 years show that perfect grains of large size and greatest weight
