white (F. C. I. No. 1482). Tri folium striatum (F. C. I. No. 1450) succumbed 

 to drought in the summer of 1915, while T. (lubium, replanted in April, 1915, 

 produced a good stand and was maturing seed in July, 1916. 



Tests of five varieties of winter rye, two of oats, and one of winter barley 

 for grain and forage were begun in December, 1915. Mexican winter was the 

 only rye variety headed out at the time of this report. The results of the oat 

 te.sts indicated yields of from 13 to 22 bu. ^Yinter barley failed to head out. 

 A second planting of five varieties each of oats, barley, and rye, and three 

 varieties of wheat was made in March, 1916. Fulghum oats was the first 

 variety to head out, with Smyrna the first barley variety. 



Kafir corn, milo maize, and feterita were grown in connection with Sugar 

 Drip sorghum for a comparison of yields of grain and forage. The yields of 

 grain per acre were 66.5, 436, 235, and 689 lbs., and of forage per acre, 6, 4.52, 

 6.65, and 11.27 tons, respectively. Tests of other grain sorghums are noted. 



New long-period tests for yields of forage were begun in August, 1915, with 

 nonsaccharin sorghum No. 309 and Japanese cane. The latter was propagate<l 

 partly by division of the roots and partly by cuttings of the cane. The first 

 cutting for forage was made December 29, and the estimated acre yield of the 

 stand from cuttings totaled 2 tons more than that from the division of roots. 



Andropogon nodosum, A. sericcus, A. saccharoides, Tricholana rosea, and 

 Giant Bermuda grass are listed as the best five drought-resistant pasture 

 grasses for low and medium elevations. Brief notes are given on numerous 

 other grasses and of a test of rape. 



Spraying Japanese nut grass with arsenite of soda when the grass is in 

 full bloom continued to be the most efCective control measure. Plowing with 

 a disk plow at intervals of four or five weeks during exceedingly dry periods 

 greatly reduced the vitality of the tubers. 



Keport of [field crop work atj the Glenwood substation, J. B. Thomp.son 

 (Ilaicaii Sta. Rpt. 1916, pp. 40-4^, pl- !)■ — I'uspalum dilatatuin has been sub- 

 jected to a number of field tests in an effort to obtain a suitable forage crop 

 for dairy cattle to supplement Commelina nudiflora and J'anicum barbinode 

 by producing *a heavy winter growth. Paspalum dilaiatum having been asso- 

 ciated with stock poisoning in the Southern States (E. S. R., 34, p. 676), 

 extreme precautionary measures are deemed necessary in introducing the plant 

 into the dairy regions. 



Volunteer plants of California bur clover were observed to make a rank and 

 rapid growth l)etween December and April, and trial plantings of this crop will 

 be made during the coming winter season. 



Edible cauna {Caiina edulis) was planted In December, 1914, in an attempt 

 ' to secure a local product suitable for hog feed. A yield at the rate of approxi- 

 mately 31.5 tons per acre was harvested in January, 1916. Further tests of 

 this crop are in progress. A portion of the harvested crop stored in ordinary 

 bags showed practically no loss from decay for a period of three months. The 

 chemical composition of the fleshy rhizome is said to be closely comparable to 

 that of the Irish potato. 



Jerusalem artichokes (Ilelianthus tuberosus) were also grown as a hog feed, 

 and yielded at the rate of approximately 11 tons per acre from a stand esti- 

 mated at only 33J per cent at the time of harvest. The artichoke was com- 

 pletely ruined by a xuoldlike fungus when stored in bags, although roots remain- 

 ing in the ground were in a perfect state of preservation over two months 

 after the bulk of the crop was harvested.
