630 EXPEBIMENT STATION RECORD. 



duced by Maltster. Among 4 wheat varieties the highest yield of good grain 

 In 1910 was produced by Scholey Squarehead. 



In a test of dung, slag, muriate of potash, superphosphate, and lime mud, 

 singly and in various mixtures and amounts, the highest yields of beans 

 followed applications of (1) 10 tons dung, 6 cwt. slag, and 1 cwt. muriate of 

 potash, and (2) 6 cwt. slag and 1 cwt. muriate of iwtash. Every application 

 tested was followed by at least li times as great a yield as was secured from 

 the check plat. 



In a fertilizer test with mangels on a loam soil with a mixed clay and sand- 

 stone subsoil, the results showed a considerable advantage of nitrate of soda 

 over sulphate of ammonia, of slag over superphosphate, and of sulphate of 

 potash over muriate of potash. A considerable advantage followed the use 

 of common salt. It appeared " that complete artificials should be used with 

 dung for this crop, the loss being greatest when nitrogen is withheld." Two 

 tons of lime per acre appeared to decrease the quantity of mangels during the 

 3 years following its application, while 4 tons of lime mud apparently reduced 

 the yield about 4^ tons per acre. 



Applications of 128 lbs. of lime nitrogen and 112 lbs. of sulphate of ammonia 

 to oats were followed by yields of 71J and 72i bu. of good grain per acre, 

 respectively, as compared with 69i bu. after the use of 140 lbs. of nitrate of 

 soda and 572 bu. per acre on the check plat In another test applications 

 of 112 lbs. of nitrate of soda and 134 lbs. of nitrate of lime were followed by 

 yields of 38 and 46f bu. of oats respectively as compared with 31 bu. secured 

 from the check plat. In an experiment on clay loam soils applications of 

 112 lbs. of nitrate of soda and 134 lbs. of nitrate of lime were followed by 

 yields of 43 and 434 bu. of oats per acre, respectively, as compared with 38f bu. 

 after 87 lbs. of sulphate of ammonia, 32f bu. after 87 lbs. of nitrolim, and 34 

 bu. on the check plat. In a test at still another point applications of 112 lbs. 

 nitrate of soda, and 134 lbs. nitrate of lime were followed by hay yields of 

 44^ and 46i cwt. per acre, respectively, as compared with 47^ cwt. after an 

 application of 87 lbs. of sulphate of ammonia and 36| cwt. on the check ijlat. 

 In a test of applications supplying 80 lbs. of nitrogen per acre to mangels the 

 yields following nitrate of soda and niti'ate of lime were 37 tons 4^ cwt. and 

 37 tons 4 cwt. respectively, as compared with 29 tons 4 cwt. and 31 tons 2 cwt. 

 respectively after the use of nitrolime and sulphate of ammonia. One- third of 

 the nitrate of soda and nitrate of lime was supplied at time of sowing and the 

 remainder in 2 equal top-dressings. 



Other experimental work on which notes or brief reports are presented 

 include flax growing, tests of various grass and clover seeds and seed mixtures, 

 a new scheme for fertilizing mangels, a fertilizer test with cabbage, variety, 

 tests of swedes, turnips, and potatoes, and studies of the effect of applications 

 of lime upon the finger-and-toe di.sease of swedes. 



Eeport on the Cawnpore Agricultural Station in the TJnited Provinces for 

 the years ended June 30, 1910 and 1911, B. C. Burt (Rpt. Cawnpore [India} 

 Agr. Sta., 1911, pp. 1-43). — Tables state in detail the data secured in rotation 

 and fertilizer tests of corn and wheat. 



In a test of calcium nitrate and calcium cyanamid as fertilizers for wheat in 



1909 applications of the 2 fertilizers at the rate of 25 lbs. of nitrogen per acre 

 were followed by yields of 1,628 and 1,543 lbs. of grain per acre, respectively, 

 as compared with an average yield of 1,403 lbs. on the unfertilized plat. In 



1910 the figures were 1,505, 1,480, and 1,075 lbs., respectively, and in 1911, 1,800, 

 1,843, and 1,695 lbs. A test of nitrate of lime as a poppy fertilizer showed a 

 marked increase but was discontinued because of the rapid reduction in opium 

 cultivation.
