232 EXPERIMENT STATION RECORD. 



Ill a lest of seed potatoes of various sizes the seed size between 1^ and 1^ in. 

 produced considerably lower yields than larger sizes, either cut or whole, for 

 which the yields were approximately equal. 



In a test of 12 applications of fertilizers and fertilizer mixtures on grass at 

 Blurton Center, the greatest increases (1 ton each) over the check plat during 

 1910, followed the use of 12 tons of farmyard manure alone and of 1 cwt. nitrate 

 of soda and 3 cwt. kainit, and of 1 cwt. nitrate of soda, 5 cwt. basic slag, and 3 

 cwt. kainit. During the 12 shears 1899-1910 the same applications resulted in 

 (he highest average yields. Similar grass experiments were conducted at 5 other 

 points. Fertilizer experiments with potatoes in 2 localities and with swedes 

 and sugar beets, 1 locality each, are also reported, and variety tests with wheat, 

 oats, and mangels. 



Report on the agricultural stations in the Central Provinces and Berar 

 for the year 1909-10, R. G. Allan, D. Clouston, and G. Evans (Dcpt. Agr. 

 Cent. Prov. and Dcrar [India] Rpt. 1909-10, pp. 67). — This report deals with 

 the work done at Nagpur, Raipur, Akola, and Hoshangabad agricultural sta- 

 tions and at the Telinkheri cattle breeding and seed farms. Earlier work at 

 these farms has already been noted (E. S. R., 22, p. 440). 



At the Nagpur station a wheat fertilizer test indicated that better results 

 followed the application of cattle dung alone than were obtained on 10 other 

 plats treated with saltpeter, bone dust, the ashes of manure, and various green 

 manures singly and in various combinations. Forty lbs. of nitrogen per acre 

 sipplied to plats planted to a cotton, sorghum, tur rotation was followed by 

 better results when the nitrogen was applied in the form of farmyard manure 

 and night soil than in the form of bone dust and saltpeter. In a 7-year test, 

 top-dressing with sufficient saltpeter to supply 20 lbs. of nitrogen per acre 

 gave better results than drilling the same amount or the use of cattle manure. 

 Applications of (1) 5 tons cattle dung per acre and (2) 2^ tons cattle dung 

 snd 2 maunds (164 lbs.) of nitrate of soda were followed by yields of 1,074 

 and 1,621 lbs. of jute fiber respectively. During the period 1906-1910 the 

 urine produced by 2 bullocks during a 30 day period and conserved in dry 

 earth was followed by approximatel5' the same yields of wheat and sorghum, 

 when applied as a fertilizer, as followed an application of both dung and urine 

 of 2 bullocks for a 30-day period, while the application of the dry excreta 

 alone was generally followed by a much lower yield. A mixture of nitrate of 

 soda, superphosphate, and sulphate of potash proved as a rule of greater value 

 in cotton growing than any one of these fertilizers or mixtures of any two of 

 them. The use of 3 maunds (246 lbs.) ]ier acre of superphosphate produced an 

 unprofitable increase in the yield of hemp fiber. 



At the Raipur station it proved profitable to transplant medium or late rice 

 which had been sown after a dressing of farmyard manure. An application of 

 calcium cyanamid supplying 20 lbs. of nitrogen per acre resulted in a greater 

 increase in 1909-10 than followed the use of dry leaves, tank silt, or castor 

 cake, but was excelled by cattle dung, bone dust, or saltpeter mixed with bone 

 dust. Nitrogen ap])lied in night soil after the Meagher system apparently 

 produced a greater increase in the wheat yield than resulted in the application 

 of 30 lbs. of nitrogen in 1 year old poudrette, or in farmyard manure, bone 

 dust, bone dust top-dressed with saltpeter, castor cake, saltpeter, green manure, 

 or tank silt, When teora, urid, and gram were sown in the standing rice 

 immediately after the rice was harvested, teora gave the best results. Wheat 

 and gram sown together at the rates of 75 and 25 lbs. per acre produced better 

 results than were obtained from sowing in the ratios of 25 : 75 or 50 : 50. In a 

 test of peanut varieties followed by wheat as a second crop, the local varie-
