 to 41. t; bn. per acre. Silver :\Iine, Great Dakota, and Czar of Russia were very 

 similar in appearance and i^ave (inile similar results. Swedish Select matured 

 about the same time as Silver Mine, Imt had a much larger and plinniter grain.

 varieties, but ^iwe considerably smaller yiehls.

The 8 satisfactory reports on tests with cowpeas showed that the varieties in 

 order of maturity ranked as follows : Early Blackeye, Michigan Favorite, Whip- 

 poorwill. Iron, and Clay. The range in yield of seed per acre was in northern 

 Indiana from' 17.1 bu. for Early Blackeye to 19.3 bu. for :Mi<'higan Favorite, 

 and in southern Indiana from 5.3 bu. for Clay to 11.3 bu. for Early Blackeye. 



Department of field experiments, P. O. Vanatter {Mri/iiiid St(t. Rpt. 1906, 

 pp. oU-UO, fjijs. .?). — The results of experiments carried on in lUOG are briefly 

 reviewed. 



Of th(> varieties of winter wheat tested Blue Ridge and Mediterranean stood 

 at the head, witli a yield of 28.52 and 2G.44 bu. per acre, respectively. Iron 

 Clad, Blue Straw Fultz, Fulcaster, and Mediterranean had the highest protein 

 content, analyzing 17.20, 10.80, 16.73, and 1G.72 per cent, i-espectively. Blue 

 Kitlge ranked thirty-second in protein content, with 14.00 per cent. Turkey 

 Red has not given good results at the station. 



Two years' experience seems to indicate that the best time to sow winter 

 wheat is from about Octobtn- 1 to October 7, but it is stated that in certain sections 

 east of the Blue Ridge sowing may be done from 2 to 4 weeks later. The work 

 in seed selection with winter wheat shows that there is not so much to be 

 gained by growing the seed from select choice heads as has been claimed. In 

 experiments here reported the general average of the results shows an increase 

 of only 3.90 bu. per acre in favor of large grains. It is believed that the safest 

 and surest way of increasing the yield of wheat is to select individual ])lants of 

 unusual promise, and work along this line has been inaugurated. 



T'nion winter barley proved to be the best stooler and to make the quickest 

 growth early in the fall. The best time to sow this crop seems to be about 

 Se])tember 15, if the land is in good condition. This season Virginia Grey 

 winter oats gave a better yield than Cidberson, which made 38 bu. per acre on a 

 ^-acre plat after cowpeas plowed luider. Varieties of winter rye have not 

 varied ntnch in yield, although Excelsior is considered the leading sort. 



Learning. Boone County White, and Cocke Prolific corn have given good results 

 on rich land. Better yields were secured from improved strains obtained by 

 crossing juire-bred western corn with tlie best native varieties than from strains 

 obtained by crossing the nativi" sorts with the western varieties without using 

 |)ure4)red strains.
