230 EXPERIMENT STATION RECORD. [Vol.38 



showod a mean yield of 38 tons of cane for nine varieties as compared witli 29.5 

 tons wltliout nitroj^en. 



Tests on 48 duplicate plats showed an increase of only 0.9 ton of cane per 

 acre upon the addition of acid phosphate, both with and without aii accompany- 

 ing nitrof,'enous fertilizer. Another series of experiments showed an increase 

 of 4 tons of cane per acre over the untreate.l plats from an application of GOO 

 lbs. of basic slag. Tests to determine the elfect of acid calcium phosphatt upon 

 the sugar content of the cane juice indicated that it was practically negligible, 

 the expressed juice showing 1.794 lbs. of sacchiU-ose and 0.061 lb. of glucose with 

 the phosphate; and 1.77 lbs. of saccharose and 0,058 lb. of glucose without it. 



A number of observations are recorded of seedling canes from selfed and un- 

 controlled parentage. Of the selected canes from uncontrolled parentage 57.2 

 per cent proved upon analysis to be of high potential value, while 5S.3 per cent 

 of the selected hybrid canes possessed similar characteristics. However, only 

 6( canes of hybrid origin were deemed suitable for analysis, whereas 430 canes 

 of uncontrolled parentage were selected. 



[Report of field crops work], A. A. Meggitt {Ann. Rpt. JorJiat Agr. Expt. 

 Sta., 1916, pp. 7-42; Ann. Rpt. Agr. Expts. Assam, 1916, pp. 7-25, ^0-^2).— Ex- 

 tensive variety and cultural tests with sugar cane are reported for 1915-16. 

 Cultural tests indicated that a planting rate of about 8,000 sets per acre was 

 the optimum for the region, and that decreasing the distance between rows 

 within the limits of from 3 to 5 ft., with the sets 2 ft. apart in the row, in- 

 creased the total acre yield. 



Liming and fertilizer tests with pigeon peas, millet, gram, mustard, corn, 

 and oats, and green manuring tests with cowpeas and pigeon peas are briefly 

 noted. Tests with wood ashes as a supplement to cow manure and in place of 

 lime have given excellent results in increased oat yields. 



[Report of field crops work at Anakapalle Agricultural Station], G. R. 

 HiLSON and D. Balakrishnamurti (Dept. Agr. Madras, Rpts. Anakapalli Agr. 

 Sta., 1914-15, pp. 6; 1915-16, pp. 7; 1916-17, pp. i2).— Cultural, rotational, and 

 variety tests with cotton, sugar cane, rice, and miscellaneous native crops are 

 briefly noted, together with meteorological data for the period of 1914 to 1917, 

 inclusive. 



Grains for western North and South Dakota, F. R. Babcock, J. H. Martin, 

 and R. W. Smith (C7. S. Dept. Agr., Farmers' Bui. 878 (1917), pp. 21, figs. 9).— 

 Approved methods of grain production in western North and South Dakota 

 and eastern Montana are outlined, and varieties of winter and spring wheat, 

 oats, barley, rye, and fiSx deemed suitable for the region recommended. 



Grains for the Utah dry lands, J. W. Jones and A. F. Bracken (U. S. Dept. 

 Agr., Farmers' Bui. 883 {1917), pp. 21, figs. 8). — This outlines approved methods 

 for the production of the small grain crops on the Utah dry lands and recom- 

 mends varieties of winter and spring wheat, oats, barley, and winter emmer 

 deemed suited to the region. Corn, the grain sorghums, proso millet, and flax 

 are said to be little grown. 



The information presented in based largely upon the results of experimental 

 work at the Nephi substation, previously noted (E. S. R., 32 p. 525; 36, p. 528). 



Leguminous crops in desert agriculture, A. and Gabkielle L. C. Howard 

 {Agr. Jotir. India, 12 {1917), No. 1, pp. 27-43; Fruit Expt. Sta. Quetta Bui. 6 

 {1916), pp. 15). — The economic necessity of producing leguminous forage crops 

 in the desert areas of India, to be used both for feed and for green manuring, 

 is discussed. Tests with the drying and baling of shaftal {Trifolium rcsupina- 

 tum) and of alfalfa are noted, and the feeding value of the two crops com- 

 pared, together with numerous reports on practical feeding tests in tlie Army.
