FIELD CROPS. 533 



different amounts per acre of timothy seed were as follows: Eight 

 qt. per acre, 2,846.94 lbs.; 10 qt., 3,732.08 lbs.; 24 qt., 3,928.14 lbs.; 

 and 32 qt., 3,732.08 lbs. '-I assume that for this poor soil 16 qt. is 

 enough, and probably too much for a richer soil." 



In 1892 the yield of dry matter on a plat sown broadcast was 3,720 

 lbs. per acre; on a drilled plat, 2,312.32 lbs. In 1893 the yield on the 

 broadcast plat was 2,907.56; on the drilled plat, 2,028. This trial 

 favored broadcast seeding, but the amount of seed used is not stated. 



The timothy meadow used in the following experiment had been 

 seeded 2 years. A plat of three-eigiiths of an acre was grazed by 2 

 heifers for 14 days, beginning November 8. A similar j)lat was grazed 

 May 16 following by 18 bead of cattle. Another plat was not grazed 

 at all. 



The yields of dry matter per acre at the next harvest were as fol- 

 lows: On the spring-grazed plat, 2,682.81 lbs.; on the fall-grazed plat, 

 4,287.36 lbs.; and on the plat not grazed, 4,030.88 lbs. 



Drilling vs. broadcasting timothy seed, J. W. Sanborn ( Utah 

 Sta. Bui. 33, pp. 6-8). — Both in 1892 and 1893 drilled timothy gave a 

 slightly larger yield of hay than broadcasted, the average yield per 

 acre for the 2 years being 1,767 lbs. of hay from broadcasting and 

 1 ,900 lbs. from drilling. The average amount of moisture at different 

 dates was 12.25 per cent on the plats broadcasted and 11.13 per cent 

 on the drilled plats. The average temperature of the soil of the 2 

 plats was practically identical. 



The effect of quicklime on the growth of leguminous plants, 

 Salfeld {JDeut. landiv. Presse, 21 {1894), M. 83, pp. 785, 786).— The 

 soil used for these experiments was a dee^), poor sand, in cultivation 

 for a long time. In the summer of 1893 it received a liberal applica- 

 tion of kainit and Thomas slag; in addition half the field was given a 

 broadcast application at the rate of 1,800 lbs. quicklime, the other half 

 was treated with marl in such quantity as to furnish the same amount 

 of lime as the quicklime. TJien the field was plowed and harrowed; 

 in IS^ovember it was again plowed and subsoiled. In February, 189^', 

 the plats intended for field j)eas (Pisum arveitse) and garden peas (P. 

 sativum), on both the limed and marled portions of the field, were inoc- 

 ulated with earth from an old pea field. Later both kinds of i^eas, 2 

 species of lentils, and Lathyrus clymenum were sown in drills. For the 

 last 3 species no inoculation was made. 



The weather up to the middle of May was dry, and up to this time 

 there was no difference in the appearance of the plants fertilized with 

 lime and with marl. After this date the rainfall was plentiful. 



By the middle of July the plants on the marled plats were luxuriant 

 and green; those on the limed plats were, with few exceptions, yellow- 

 ish. On examining the roots it was found that the yellowish plants 

 had no root tubercles; the green plants on the limed plats had many
