36 EXPERIMENT STATION RECORD. 



ill Bulletin 23 of the station (E. S. R., 4, \). 815). Pringle Progress oats 

 were sown at the rate of 1, 1^, 2, 2i, 3, 3i, and 4 bus. per acre on 7 

 plats. The results for 1893 differ from the average results of 6 years 

 chiefly in that 1 bu. of seed per acre gave almost as much grain as 2^ 

 bus. Pringle Progress oats wen? so\yn broadcast on some plats at 

 the rate of 80 lbs. of seed per acre, on others at the rate of 100 lbs., on 

 March 31, Ai^ril 8, April 17, May 3, and May 10. Tlie earlier sowing- 

 gave the largest yield and later sowiugs a uniform decrease in yield. 

 In rows 10 ft. long selected kernels were planted at depths of 1, 2, 3, 

 4, 5, and 6 in. The largest yield was from planting 1 in, deep. 



Tables showing the yield of oats harvested (1) early, (2) medium 

 ripe, (3) fully ripe, (4) bonnd and shocked soon after cutting, (5) allowed 

 to dry thoroughly before binding, and (G) simply headed, are quoted 

 from Bulletin 23 of the station. Chemical analyses of the grain and 

 straw grown in 1891 and 1892 and of the stubble of 1892 were made. In 

 1891 there was no notable difference in comi^OvSition of the grain due 

 to time or manner of harvesting. In 1892 the lU'otein and fat were 

 slightly higher for the early curing and for those bound and shocked. 



Varieties of potatoes, H. T. French {Oregon ^ta. Bui. 30, pj). 09- 

 73). — One hundred and tifty-three varieties of potatoes were grown on 

 the station farm in 1893, 88 being on plats large enough to warrant a 

 calculation of the yield per acre. The varieties recommended are 

 Dublin Chief, James Vick, Burling, White Lion, Thorburn Late Kose, 

 Dakota Red, Tilden, Early Sunrise, Rochester Favorite, and Silver 

 Skin. Of the newer varieties Coy Seedling Ko. 88, Salt Lake Rose, 

 and Van Orman Superb are mentioned as promising. 



Roots, H. T. French [Oregon Sta. Bui. 30, pp. 74-78, pis. 5).— Tests 

 of 4 varieties of mangel-wurzels, 3 of carrots, and several of rutabagas. 

 Orange Grove was the most productive of the mangel-wurzels. Masto- 

 don of the carrots, and Yellow Swedish of the rutabagas. 



Investigation of roots, F. H. Werenskiold [Rpt. Chem. Control 

 Sta. Christiania, 1893, pp. 11-27). — Through the various county agricul- 

 tural societies 90 samples of roots of various kinds were sent to the sta 

 tion for examination. Information is given in the report on the origin 

 of the samples, their period of growth, yield, soil on which they were 

 grown, fertilizers applied, etc. The samples analyzed included 7 dif- 

 ferent varieties of carrots, 4 of rutabagas, 5 of yellow turnii)S, (5 of white 

 turnips, and of mangel-wurzels. The extremes of composition found 

 are given in the following table:
