528 EXPERIMENT STATION RECORD. [Vol.35 



Notes are given on culture tests with clover, sweet clover, Crotalaria 

 mesopontica, C. madurensis, C. incana, C. striata, Stisolohium hassjoo. S. 

 cinereum, and S. capitatum. Jack beans and species of velvet beans sown early 

 in September gave the best yields of both green substance and seed. The fol- 

 lowing annual yields of green forage from different varieties of alfalfa are 

 reported : Spanish .56,362 lbs., Kansas common 52,00.5 lbs., Utah common 45,245 

 lbs., Peruvian 35,530 lbs., and Turkestan 30,595 lbs. per acre. Semipalatinsk 

 alfalfa (Medicago falcata) did not prove equal to common alfalfa or Japan 

 clover (Lespedeza striata). 



The total yields of green forage per acre for a period of 26.5 months for 

 the sorghums and 27 months for the Japanese cane are recorded as follows : 

 Sweet sorghum, 8 cuttings, 86.55 tons ; nonsaccharin sorghum. 6 cuttings, 88.45 

 tons ; and Japanese cane, 3 cuttings, 157.64 tons per acre. The results with 

 other varieties of sorghum are also noted. 



Of the several forage grasses on trial, Sudan gi-ass retained its lead in the 

 production of green forage, yielding at a low elevation an average of 14.5 tons 

 per cutting per acre for 7 cuttings as compared with an average of a little less 

 than 4 tons per acre for 6 cuttings for Tunis grass. The value of other gi-asses, 

 including molasses, Wilder, Australian blue, Giant Bermuda, teff, Mitchell, 

 wallaby, side oat grama, Judd, and American buffalo grass, is briefly men- 

 tioned. Japanese millet is reported as maturing at the station in 80 to 100 

 days under ordinary conditions and as yielding about 10 tons of forage per 

 acre when cut green and 3 tons of roughage and 30 bu. of seed per acre when 

 left to mature. The best results in controlling the spread of Japanese nut 

 grass Avere secured by spraying with arsenite of soda. 



Japanese buckwheat was found to mature a week earlier than SilverhuU and 

 to yield about 25 per cent more grain. The average annual yield per tree for 

 4 years of Caravonica cotton planted on the station grounds in February, 1910, 

 was approximately 1 lb. of lint. The distribution of seed of cotton and grasses 

 conducted by the department is briefly mentioned. 



[Work with field crops in 1915] {Wisconsin Sta. Bui. 26S {1916), pp. 4-6, 

 10-15, 32, 36, figs. 10). — In connection with the work of the agronomy depart- 

 ment with pedigreed strains of rye, an improved strain known as Pedigree No. 

 1, and excelling in stiffness of straw and milling qualities, was developed from 

 the Schlansted variety. A yield of 46.5 bu. per acre under field trials, or 14.5 

 bu. over the yield of common varieties, is recorded. A cross by E. J. Del- 

 wiche between Minnesota 169 and Red Fife wheat produced a strain with 

 exceptional stooling power, marked resistance to rust, a strong straw, and 

 early maturing qualities. In 30 tests at the station by R. A. Moore and B. D. 

 Leith with wheat, Pedigree No. 2, a type of Turkey Red winter wheat, yielded 

 49.6 bu. per acre and Marquis spring wheat 43 bu. Milling and baking tests 

 with 21 samples of the 1914 crop showed that Pedigree No. 2 gave fully as 

 good results as the standard spring wheats of highest milling quality. The 

 Wisconsin spring wheats analyzed 12.46 per cent of gluten as compared with 

 11.05 in the standard spring wheat patent flours. 



The work of the station to establish hemp growing in the State, conducted 

 by C. P. Norgord, is described and the progress made in this direction is noted. 

 The results of comparative trials of over 200 strains and varieties of alfalfa 

 by L. F. Graber indicated that the common purple-flowered alfalfa from Kansas 

 and Nebraska seed witlistood winterkilling last winter quite as well as alfalfa 

 from northern-grown seed. Pedigree No. 4 and White Jewel oats grown in the 

 Superior district were found by E. J. Delwiche to be the most resistant to the 

 influences causing lodging. Yields of 2.5 to 3.7 tons of hay per acre are reported
