826 EXPERIMENT STATION" RECORD. [Vol. 41 



The liighest j-ield in the contiuuous barley experiiueuts was secured from 

 the plat receiving farmyard manure and amounted to 35.1 bu. of grain and 

 2,238 lbs, of straw, followed by the plat receiving mineral manures and, in 

 alternate years, nitrate of soda with a yield of 27 bu. of grain and 1.555 lbs. of 

 straw. The average yield for the untreated checks was 8.6 bu. of grain and 

 587 lbs. of straw. Mineral manures alone failed to give any increase in yield 

 although a slight increase was secured on the limed portion of the plat. Sul- 

 phate of ammonia alone again gave no weighable return, while the addition 

 of large amounts of lime (4 tons) resulted in an increased yield. Nitrate of 

 soda used alone at the rate of 2 cwt. (224 lbs.) per acre gave satisfactory re- 

 sults. Rape cake proved to be a failure with barley. Phosphate without 

 potash produced 24.3 bu. of grain and 1,365 lbs, of straw and potash without 

 phosphate 25.4 bu. of grain and 1,547 lbs. of straw. 



Observations on the comparative effect upon barley yields of the unex- 

 hausted residues from so-called cake and corn feeding on the rotation plats 

 showed a yield of 21.8 bu. of grain and 1,431 lbs. of straw for the corn-fed plat 

 and 18.2 bu. of grain and 1,496 lbs. of straw for the cake-fed plat. 



Wheat following green crops of tares, rape, and mustard which had been fed 

 off produced at the rate of 12.2, 15.3, and 15.2 bu. of grain per acre, respectively. 



In the improvement of old grassland, the best results were again secured 

 from an application of 12 tons of manure per acre made in 1913 with a yield 

 of 3.870 lbs. of hay, as compared with 3,668 lbs. for the untreated check. 

 Various kinds of lime for grassland have been compared, the highest yield, 

 3,808 lbs. of hay per acre, being secured from Lias lime applied in 2-ton lots in 

 1910 and again in 1916. The untreated check produced 3,752 lbs. of hay. 

 Comparing different forms of lime for grass, ground chalk gave the highest 

 yield, 3,836 lbs. of hay, and the untreated check 3,360 lbs.

 Depf. Mysore, 1916-11, pp. 2-6). — Variety, fertilizer, and cultural experiments 

 with sugar cane are briefly described and held tests with miscellaneous croiis 

 noted.

Grain yields for 1919, E. B. Stookey {Washington Sta., M^est Wash. Sta. 

 Mo. Bui., 7 (1919). No. 7, pp. 105, 106). — The yields of the leading varieties of 

 barley, oats, and wheat grown at Puyallup during 1919 are given, together 

 with their average yields for a period of years. 



Barley yielded at the rate of from 23.38 bu. per acre for Beardless to 39.8 

 bu. for Hannchen for a 3-year period. Gray Winter oats sown in the fall pro- 

 duced 48.17 bu. for a 4-year average as compared with yields of spring varieties 

 ranging from 49.77 bu. for Swedish Select to 60.6 bu. for Minnesota No. 281. 

 The 4-year average yields of spring wheat ranged from 18.21 bu. per acre for 

 Marquis to 22.42 bu. for Mexican Bluestem, and of winter wheat from 33.43 bu. 

 for Little Club to 35.23 bu. for Red Russian. Red Russian seeded at the rate 

 of 1.5, 2, and 2.5 bu. per acre produced at the rate of 31.25, 35.2, and 36.75 bu. 

 per acre, re.spectively. 



Statistical notes on cereals (Intrrnafl. Inst. Agr. [Rome], Bur. Statis.. Doc. 

 Leaflets, 3 {1919), No. 6, pp. 88).— Statistical information is presented dealing 

 with the yield, trade, consumption, prices, and rates of ocean freight for wheat, 

 rye, barley, oats, corn, and rice throughout the world for the 1918 crops of the 

 Northern Hemisphere and the 1918-19 crops of the Southern Hemisphere. In-
