alone. Timothj', redtop, and clover mixed yielded 5,440 lbs. as compared with 

 4.460 lbs. of timothy and redtop, 3,307 lbs. of redtop alone, and 3,857 lbs. of 

 timothy alone. In 1009 spring and August seedlings j'ielded 1.86 and 2.1 tons 

 per acre respectively of a mixture of sapling clover, timothy, and redtop. 



An application of 1 ton of burnt lime and 300 lbs. nitrate of soda per acre 

 was followed by an average hay yield of 4,402.5 lbs. per acre during 1909 and 

 1910 at Appomattox. Applications of 300 lbs. nitrate of soda and 1 ton of 

 burnt lime produced yields of 3,127 lbs. and 3,699 lbs. respectively as compared 

 with 2,215.5 lbs. per aci*e on the check plat. The same applications at Bowling 

 (Jreen during 1910 alone were followed by yields of 3,375, 3.160, 2,055, and 

 1,950 lbs. of hay per acre respectively. 



In a test at Appomattox of the residual effect of fertilizers applied to 

 tobacco during 1907 and 1908, applications of (1) 700 lbs. acid phosphate and 

 400 lbs. nitrate of soda, and (2) 400 lbs. bone meal were followed by the 

 highest average hay yields during 1909 and 1910 from 8 different combinations 

 of acid phosphate, sulphate of potash, nitrate of soda, and a 3:8:3 fertilizer. 

 At Bowling Greon 1.500 lbs. of cotton-seed meal applied to tobacco in 190S was 

 followed by a hay yield of 2,400 lbs. per acre in 1910 as comi)aretl with 1,200 

 lbs. after an application of 500 lbs. of a 3:8:3 fertilizer and an average yield 

 of 1,040 lbs. on unfertilized plats. The author believes that potash applications 

 to grass land do not pay except perhaps on sjindy soils from which plant food 

 leaches rapidly. Nitrate of soda was found to have little residual effect after 

 2 years. 



Applications of (1) 100 lbs. of muriate of potash and 150 lbs. of dried blood 

 and (2) 100 lbs. muriate of potash, 200 lbs. acid phosphate, and 150 lbs. dried 

 blood were followed by yields of 3.12 and 3.18 tons of cured hay per acre at 

 Blacksburg in 1909. In 1910, however, the highest yield followed an applica- 

 tion of 200 lbs. of 16 per cent acid phosphate. Slightly increased yields also 

 followed applications of 1 ton of burnt lime and 100 lbs. nitrate of soda 

 per acre. 



At the end of the third year after seeding a plat which produced a little 

 over 1 ton per acre was plowed and reseeded without fertilizer. The next 

 year it yielded 2i tons and the following year only 2 tons, indicating that 

 timothy and clover deteriorate after the second year on this soil. 



Grasses, A. M. Ten Eyck (Kansas Sta. Bui. 115, pp. 291-39Ji, figs. J/O). — 

 Dii-ections are given for growing, harvesting, and utilizing grasses adapted 

 to Kansas conditions and experiments along these lines are reported. 



During the 4 years 1905-1908 common alfalfa and Turkestan alfalfa ex- 

 celled the other hay crops with yields of 8.420 and 6,875 lbs. of hay per acre 

 respectively. Bromus inermis and alfalfa mixed yielded 6,576 lbs. and timothy 

 alone yielded 5,528 lbs. It was noticed that the yields of B. inermis and 

 meadow fescue decreased each year after the first crop was cut. Orchard 

 firass was less uniform in this respect. 



During 1905 determinations of moisture in samples of various hays at 

 stacking were made and are presented in tabular form. Figures for the years 

 1905-1908 and 1909 show that the moisture content of the same kind of hay 

 may range from 13.95 to 31.45 per cent or even more widely in different years. 

 Hay stored before it is fully cured " may readily lose 15 to 20 per cent in 

 weight after being put into the mow or stack, due to loss of moisture alone." 

 In 1909 the average moisture content of the 4 cuttings of alfalfa when stacked 

 was 29 per cent. Green alfalfa shows about 80 per cent of moisture at the 

 first cutting and 70 per cent at the second cutting. A table summarizes ex- 

 periments in breaking and cropping prairie sod and reports the yields secured 

 of flax, spring wheat, oats, corn, and other crops.
