532 EXPERIMENT STATION RECORD. 



Tlie experiments with tiax at the station are reviewed and it is shown that in 

 1905 yields of flax seed from 8 different varieties ranged from 168 to 443.2 lbs. 

 per acre. 



Report of the chemists, H. G. Knight and F. E. Hepner (Wyoming Sta. Rpt. 

 J 907, pp. 68-67). — In connection with brief notes on the various lines of work 

 conducted by this department, analyses of summer and winter samples of west- 

 ern wheat grass {Agropyron occidentaJe), Indian millet (Eriocoma cuspidata) , 

 needle grass {Stipa comatd), and prairie June grass (Kceleria cristata) are 

 reported. 



Experiments with oats, m.illet, and various legumes, A. M. Soule and P. O. 

 Vanatter {Virginia /S7a. Bui. J 68, pp. 261-^90, figs. 11). — Among the best vari- 

 eties of spring oats tested were Silvermine, Texas Rust Proof, and New AYhite 

 Sensation, yielding 27.18, 26.53, and 25.98 bu. per acre, respectively. The seed 

 of Silvermine, planted in 1905, contained 8.98 per cent of protein. The crop 

 secured from this seed contained 16.20 per cent and the crop of 1906, 16.50 per 

 cent. The seed of Texas Rust Proof, secured in 1905, contained 13.33 per cent 

 of protein, and the resulting crop 13.81 per cent, while the crop of 1906 con- 

 tained 15.14 per cent. The percentage of hulls of the different varieties of oats 

 varied from 28 to 43 in the seed and from 30 to 43 in the resulting crop. Tetch 

 and oats seeded in various proi)ortions yielded from 0.90 to 1.57 tons of hay per 

 acre, with the i)roportion of vetch in the gi'een crop never more than 12.68 i)er 

 cent and in many instances less than 2 per cent. 



Among the best varieties of millet were (ierman, Japanese, and Hungarian, 

 yielding in 1905 and 1906 on an average 3.85, 2.80, and 2.42 tons of hay per acre, 

 respectively. 



Up to the present time Whippoorwlll. Iron, New Era. and Biack cowpeashave 

 given the best results at the station for hay making, the avei'age yields for the 

 years 1905 and 19<X) being 2.50, 2.43, 2.40, and 2.23 tons per acre, respectively. 

 The following yields of hay were secured from soy beans : Ito San Yellow 2.156 

 tons per acre. Early Green 1.63 tons, Japanese Pea 1.90 tons, Hollybrook 2.95 

 tons. Mammoth Yellow 2.S5 tons, and Extra Early Yellow 2.30 tons. The best 

 average grain yields were as follows: Ito San Yellow 18.43 bu. per acre, Early 

 Green 16.16 bu., Japanese Pea 15.20 bu., and Metlium Green 14.53 bu. Inocu- 

 lation tests with soy beans and field peas were without apparent results. 



The best varieties of field beans grown at the station in 1905 and 1906 were 

 Choice NaA-y, which made an average yield of 22.50 bu. ; Burlingame, which pro- 

 duced 19.78 bu. ; Choice Mediterranean, .which produced 18.20 bu. ; and White 

 Marrowfat, which produced 17.75 bu. per acre. Canada field peas at the station 

 have thus far failed to give a large enough yield of grain or hay to prove 

 remunerative. 



Report of the agronomist, R. E. Hyslop {Wyoming Sta. Rpt. 1907, pp. 126- 

 140, figs. 2). — The lines of work conducted in the department of agronomy are 

 briefly noted and the results of cooperative investigations of cereals by the 

 station and the Bureau of Plant Industry of this Department in 1906 are 

 tabulated. 



Intercultural tillage of wheat and oats on ground worn out by continuous 

 cropping resulted in maintaining a darker color in the growing crop through- 

 out the season than on the plat where no cultivation was given. Field peas 

 sown at a rate to supply 193,600 plants per acre produced 5,794 lbs. of straw 

 and 606 lbs. of seed, which was a larger yield of both straw and seed than 

 on the plats where the stand was thinner. The use of nitrate of soda in 

 growing a plat of hulless barley api»areutly gave a large increase in the yield 

 of straw and grain.
