594 EXPERIMENT STATION RECORD. 



Experiments with wheat, C. C. Geokgeson, F. C. Burtis, and 

 D. H. Otis {Kansas Sta. Bid. 59^i)-p. 89-105). — Tbis is a coutinuatiou of 

 work reported in Bulletin 47 of tlie station (E. S. R., 6, !>. 538). Tabu- 

 lated data are given for the experimental work noted under eack sub- 

 title. 



Wheat grown continuously without manure (pp. 90, 91). — With an aver- 

 age on the experimental acre of 25.25 bu. for 13 crops harvested during 

 IG years the yield for 1896 was 24.85 bu. The authors state that the 

 yield is falling off. 



EarJy and J ate plowing (pp. 91, 92). — Laud was plowed July 20 and 

 September 3, and seeded September 18. The plats plowed in July 

 averaged 23.G6 bu., and those plowed in September, 19.74 bu. 



SuhsoiUng vs. surface plowing (pp. 92-94). — The yield was larger 

 where subsoiling was done 6 weeks before seeding than on plats plowed 

 in the ordinary way. Plats subsoiled a year before seeding and which 

 had borne a crop of peas in the interim gave no increase over the 

 plowed i)lats. 



Time of seeding wheat (pp. 94, 95). — The results are given for 4 plats 

 seeded on 8 different dates from September 13 to November 1, inclusive, 

 with intervals of 7 days. Seeding on September 20 gave the best 

 average yield. 



Seeding at different rates (pp. 95-97). — Seven series of 5 plats each 

 were used. Seed was sown at the rate of from ^ to 2 bu. per acre, the 

 unit of increase being 1 peck. The thin seeding tillered more than the 

 thick seeding. The highest yield was given by the 2 bu. rate. 



Grading seed wheat (pp. 98, 99). — Wheat from the thresher was sep- 

 arated into light and heavy grades, and these were compared with the 

 ungraded seed. The light, common, and heavy seed weighed 44.75, 

 52.75, and 58 lbs. per bushel, respectively, and the corresponding yields 

 were 34.89, 36.19, and 35.39 bu. The average of 4 years shows a slightly 

 larger yield from the heavy wheat. 



Effects of pasturing wheat (pp. 99, 100). — Ten out of 15 plats were 

 grazed in the fall during 12 hours and in the spring during 10 hours by 

 one cow on each plat. The pasturing apparently did no harm. 



Wheat in rotation (pp. 100-102). — Twenty tons of manure seemed to 

 be excessive for wheat, as the yields averaged smaller than with con- 

 tinuous cropping without manure. 



Test of varieties (pp. 102-104). — On 47 twenty-fifth-aere plats 35 vari- 

 eties were tested. The Turkey wheat is promising because it yields well 

 and is hardy. On an average of several years the 6 varieties giving 

 the largest yields are Andrews No. 4, Turkey, Valley, Tasmanian Red, 

 Ramsey, and Currell. 



Wheat experiments, 1895-'96, G. E. Morrow ( Oldahoma Sta. Bui. 

 20, pp. 1-9). — Sixty- five varieties of wheat were tested. Hybrid Medi- 

 terranean, Nigger, and Missouri Blue Stem, among the bearded varieties, 

 and Michigan Amber, Early Red Clawson, and Fultz, among the smooth,
