19181 FIELD CROPS. 433 



given good results, especially when applied at the rate of 9 cwt. per acre. Basic 

 slag was found to be inferior to acid phosphate, and nitrate of soda to sulphate 

 of ammonia on peaty soils. 



Red Marvel spring wheat gave the higliest yield, with about 48.5 bu. per 

 acre, with Red Fife second with about 47.6 bu., while of the winter wheats 

 tested White Stand-up, with a yield of approximately 45.7 bu., and Queen 

 Wilhelmina, with about 44.8 bu. were best. Fertilizing wheat after root crops 

 was not deemed profitable, but after grass or another grain crop an application 

 of from 2 to 3 cwt. of acid phosphate supplemented by 1 cwt. of sulphate of 

 ammonia in the spring is recommended. 



Agricultural experiments. — Report for year 1915—16, W. J. Spafford, A. A. 

 KiLSBY, F. Coleman, and L. J. CJook (Jour. Dept. Agr. So. Aust., 20 (1917), No. 

 S, pp. 602-613). — Variety tests with potatoes, oats, barley, and wlieat, and fer- 

 tilizer tests with potatoes and wheat are reported for three experimental 

 centers in South Australia. 



The highest potato yield, approximately 8,337 lbs. per acre, was secured from 

 an application of G cwt. of lime and 1 cwt. of sulphate of potash as compared 

 with a yield of about 8,071 lbs. obtained from the untreated check. 



The highest average wheat yield, 2G.55 bu., in fertilizer tests extending over 

 a period of 12 years, 1905-1916, inclusive, was obtained from an application of 

 1 cwt. of rock phosphate, 0.5 cwt. of sulphate of potash, and 0.5 cwt. of nitrate 

 of soda. A yield of 15.17 bu. was obtained from the untreated check.

 (Dept. Agr. Madras, Rpt. Coimbatore Agr. Sta., 1913-lIt, pp. 38; 191Jt-15, pp. 27; 

 1915-16, pp. 22; 1916-17, pp. 19). — In a continuation of work previously noted 

 (E. S. R., 31, p. 733), variety, cultural, and fertilizer tests are reported with 

 rice, millet, wheat, ragi, cumbu, cotton, gram, sugar cane, and miscellaneous 

 fodder crops for the period of 1013 to 1917, inclusive. Brief notes on meteor- 

 ological conditions for the period are included. 



[Field crops work at the Hagari Agricultural Station], G. R. Hilson (Dept. 

 Agr. MadraH, Rpt. llagari Agr. Sta., 1913-U, pp. 22; 1914-15, pp. 16; 1915-16, 

 pp. 25; 1916-17, pp. 20). — Variety and individual selection tests with cotton, 

 grain sorghums, ragi, potatoes, and sugar cane ; tests of oil cake and sheep and 

 cattle manure as organic fertilizers; rotation tests with sorghum, gram, millet, 

 and cotton ; cultural tests with millet and ragi ; and fertilizer tests with sugar 

 cane are briefly reported for the period of 1913 to 1917, inclusive. 



Higher yields of sorghum, grain and forage, were obtained with sheep manure 

 than with oil cake or cow manure. The highest yields of grain and fodder were 

 obtained from rotations of sorghum with Bengal gram. Peanuts used as a 

 green nianure for sugar cane, and supplemented by 200 lbs. of acid phosphate 

 gave increased yields of cane over gz'een manuring alone.

 D. Ananda Rao, and K. Ramasastrulu Nayudu (Dept. Agr. Madras, Rpt. 

 Nandyal Agr. Sta., 1913-U, pp. 9; 19U-15, pp. 10; 1915-16, pp. 8; 1916-17, pp. 

 9). — Cultural, variety, and manurial tests with sorghum, cotton, and miscella- 

 neous cereal and fodder crops are reported for 1913 to 1017, inclusive, with a 

 brief discussion of local agricultural conditions. 



Experiments with clovers and grasses, F. G. SxEnLER (Landw. Jahrb. 

 Schtveiz, 31 (1917), No. 1, pp. 1-43, figs, ii ) .—Comparative field tests of French, 

 Spanish, Syrian, Persian, and South Russian alfalfas, eight different clovers, 

 and six grasses are reported. The tabulated data show the green and air- 

 dried weight of the forage, together with a report on the percentage of purity 

 and germinability of the seed, the percentage of usable seed, and the weight of 

 1,000 seeds for each variety tested.
