Hairy vetch for green manuring, L. Sohirmer {Siichs. landir. 

 Zfschr., 18'J-i, Auff. 11; ahs. in Join: Ac/r. Prat., 58 {1894), No. 34, pp. 

 205, 2G(;). — The author conducted experiments near Magdeburg, Ger- 

 many, for several years to determine the relative value as a green 

 manure of hairy vetch, white lupines, blue lupines, yellow lupines, flat 

 pea, and serradella. The i)lants were sown under two ditterent condi- 

 tions, (1) in the spring in a growing grain crop, and (2) immediately 

 alter the grain harvest. Late in the season the green growth was 

 plowed under and i)()tatoes planted the following year. The amount 

 of nitrogen contained in the leguminous crops per acre ranged 

 between 44J and 8!) lbs., depending upon the phmt employed. The 

 vetch aftbrded the largest amount of nitrogen and gave the largest 

 yield of i)otatoes in the following year. The potato crop following- 

 yellow lu])ines was smallest. 



When it is desired to save seed of hairj^ A'etch the author recom- 

 mends sowing a mixture of | vetch and % rye; when forage is desired 

 the proportion is reversed. 



Field experiments with wheat, G. E. Morrow and F. D. 

 Gardner {Illinois Sta. Bui. 34, pp. 402-411). — A test of varieties, of 

 mixtures of varieties, and of the thickness of sowing. Of GO varieties 

 tested, the largest yields in 1894 were made by New Michigan Amber, 

 Yellow Gypsy, Crate, Rock Velvet, IJoyal Australian, Currell Prolific, 

 Diehl Mediterrauean, and Missouri Blue Stem. 



"Thirty-seven plats of bearded wheat averaged .S5, and 30 plats of smooth averaged 

 36.8 bu. Thirteen plats of wheat classed as white averaged 34.7, and 56 classed as 

 brown or red averag(!d 35.8 bu. . . . The average number of stubs on 1 s(\. ft. 

 was 51, the range being from 34 to 65. . . . The average weight of 100 kernels of 

 wheat in 1894 was 3.35 gm., the range- being from 2.40 to 4.04. . . . The average 

 unmbei of kernels per bushel of the wheat grown at this station this year was a 

 little over 800,000, the extremes being about 600,000 and 1,130,000. . . . 



"In 1892 the yields of each of 4 ))lats sown with a mixture of several varieties was 

 somewhat greater than the average of the varieties composing this mixture. Seed 

 from these mixtures was sown in fall of 1893. In Itut one case was the yield greater 

 than the average yield of all the jdats, and in l)ut oue was it greater than that of 

 the plats adjoining." 



Tabulated data give the percentage of germination, the date of 

 ripening and harvesting, length of straw, character of the plant, 

 number of stubs per s(|uare foot, Aveight of 100 kernels, weight per 

 bushel, and the yield of straw and grain per acre. The yields of 

 varieties grown for a number of years at the Indiana, Ohio, and Penn- 

 sylvania Stations, as well as the Illinois Station, are given. In a list 

 of 2.") varieties, each of which had been tested 7 or more times, the 

 following gave the largest average yields for the 4 stations: Poole, 

 Valley, Koyal Australian, lied Tasmanian, and Nigger. 



Wheat at the rate of 3, 4, 0, 7, 8, and ])ecks of seed per acre was 

 sown. The largest yield in 1894 resulted from the use of 4 pecks of 

 seed. For the preceding ."» years the average results were slightly in 

 favor of sowing 8 pecks per acre.
