and Miuuesota No. 550 and Beloglina with 25 bu. Miuuesota No. 2 rye yielded 

 42.5 bu. per acre, Minnesota No. 1, 41.4 bu., Ivanoff 40.3 bu., Petkus 35.7 bu., 

 and Schlansted 32.8 bu., wliiie Olds Mammoth Si»riuj; produced only 20.7 bu. 

 I)er acre. Two new varieties l>red from Schlansted and I'etlius foundation will, 

 go into the increase plats in lOOS. 



The varieties of corn under test were Silver King, Golden Glow, Smut Nose 

 tlint, and Early Yellow Dent. These varieties were tested by the ear-to-the- 

 row method. Thirty-seven ears of Silver King ranged in seed ear production 

 from l;) lbs. to 61 lbs., and in total yield from 83 lbs. to 270 lbs. A row of the 

 1900 crop was left standing through the winter to determine its vitality. In 

 the fall the row was thoroughly matured before freezing weather and all 

 ears showed a uniform germination of 100 per cent prior to zero weather. 

 After the thermometer had registered below zero the viability of the corn im- 

 mediately dropped in all ears with the excet)tion of one, which gave a test of 

 100 per cent throughout the winter. The progeny of this ear, however, did 

 not show the vigor of the kiln-dried corn nor did it produce any greater number 

 of good seed ears. The general corn field of 18 acres planted with tested seed, 

 the progeny of high-yielding rows from the seed plat of 1906, gave an average 

 yield of G3.8 bu. of seed corn per acre. The approximate cost of production 

 per bushel is estimated at 29.5 cts. 



Oderbruck barley tested near the Iron Kiver farm yielded 36 bu. per acre. 

 At Ashland and Superior this barley yielded 20 bu. per acre in an unfavorable 

 season. In trials of brewing barleys, many of which were not acclimated, only 

 low yields were secui-ed, partly because of the dry season. 



Swedish Select oats gave 20 bu. per acre at Superior, 12* bu. at Iron River, 

 and an average of IS bu. at Ashland. The weight per bushel averaged 38 lbs. 

 at Ashland and Superior and 33 lbs. at Iron River. Sixty Day and Tobolsk 

 stood first in rust resistance but last in yield. 



The winter wheat varieties grown at Ashland and Iron River suffered from 

 winter-killing and gave low yields. The best showing was made by Beloglina, 

 Kharkoff, and Padii. 



Silver King corn at the Iron River farm gave a yield of 12 J tons of silage 

 corn and 84 bu. of ear corn per acre, and Early Yellow Dent 10 tons of silage 

 and 55 bu. of ear corn. The corn had matured when frost came on September 

 25. Several varieties of flint corn tried at Superior and at Ashland did not 

 reach full maturity. 



A good stand of alfalfa was secured on the Iron River farm by sowing the 

 seed in the fall of 1906. In 1907 the field was clipped three times and by 

 September 20 the alfalfa was a foot high, apparently well established, and 

 almost of a perfect stand. The field had been inoculated with soil and nodules 

 were abundant on the roots of the plants. Soy beans were ripe September 20 

 and gave a yield of 12 bu. per acre. Soil inoculation in this case also seemed to 

 have favored the development of the nodules. Thirty-seven strains of medium 

 red clover were sown in the spring of 1907 on the Iron River farm, and on the 

 whole a fair catch was secured, although dry cold weather affected the stand. At 

 Superior alsike clover yielded 5 bu. per acre, and near Ashland 8 bu. of clean 

 seed was secured on a 1-acre tract.
