nemoralis), sweet vernal grass {Anthoxanthum odoratum), meadow fox- 

 tail {Alopecuriis pratcnsis), mainmoth red clover {TH/olium medium) 

 alfalfa {Mediccujo sativa)^ alsike clover ( Tri/olium hybridum), and crimson, 

 clover {TrifoHum incarnatum). The best results thus far have been 

 with meadow fescue, tall fescue, tall meadow oat grass, and mammoth 

 red clover. 



Experiment No. 10. — Grasses and clovers, test of varieties and mixtures 

 (pp. 485-487). — Medium and alsike clover, orchard grass, and timothy 

 singl}', timothy with mammoth, medium, or alsike clover, and orchard 

 grass with medium or alsike clover were sown in 1888 on 9 two-acre 

 plats. The time of cutting and yields of hay in 1889 and 1890 are 

 tabulated for each plat. 



The time of cutting, as well as the field notes, indicate that alsike clover ripens 

 earlier than medium red clover; that medium red clover and orchard grass ripen 

 about the same time ; that timothy ripens from 3 to 5 weeks later than medium red 

 clover and about the same time as mammoth red clover. * * « 



The largest yield of hay, 2.7 tons per acre, was from timothy and mammoth clover 

 Sown together, which during the 2 years gave a larger yield at two cuttings than 

 timothy and medium red clover at three cuttings. 



Timothy gave the largest yield, 2.2 tous per acre, of any single plant, giving a lit- 

 tle more at two cuttings than did medium red clover at three. 



Orchard grass gave a little larger yield than alsike clover, but both yielded very 

 much less either when sown alone or sown together than did timothy or red clover. 

 They yielded less when sown together than when sown alone. Orchard grass and 

 red clover, and timothy and alsike clover gave poorer yields than timothy and red 

 clover. 



Experiment No. 86. — Effect of fertilizers on Kentucky blue-grass (pp. 

 487-489). — Superphosphate, muriate of potash, and nitrate of soda, 

 singly and all three together, horse manure, cattle tankage, and gypsum 

 were applied in 1889 and 1890 " to a Kentucky blue-grass pasture of at 

 least 15 years' standing." The tabulated results, as compared with 

 those on three plats receiving no manure, indicate that the greatest 

 increase of yield was caused by horse manure. 



Neither potash salts nor nitrate of soda when used singly at the rate of 200 pounds 

 per acre materially increased the yield. Nitrate of soda always gave the grass a 

 greener color. Gypsum, at the rate of 500 pounds per acre, seemed to have no effect. 

 The use of superphosphate, muriate of potash, and nitrate of soda together increased 

 the yield 67 per cent. Estimated as heretofore, the increase would be worth $2.68. 

 The cost of the application was about $16 per acre.
