538 EXPEKIMENT STATION RECORD. 



iiud 7.875 tons per acre; respectively. The use per acre of 7.5 lbs. each of acid 

 phosphate and muriate of potash and 8 tons of barnyard manure before plant- 

 ing, and the application of 100 lbs. of nitrate of soda just before tasseling, is 

 considered remunerative. 



Experiments in the culture of corn, M. de Flacourt {Bui. Econ. Itido-Chine, 

 n. sen, 12 (1909), No. 76, 'pp. 55-59). — Experiments were conducted at the ex- 

 periment station of Thanh-Ba, Tonkin, with 2 native varieties and 1 introduced 

 variety of corn. The introduced variety, Ivuowu as Petits Cotons, gave better 

 results than the 2 native sorts when cultivated either on rice lands or on roll- 

 ing ground. 



Corn culture, J. M. Kimbrough {Georgia 8ta. Bui. S-'i, pp. 211-220, flg. 1).— 

 A test with 13 varieties of corn resulted in the heaviest yields from Marlboro 

 Prolific, Stone Flint, Granberry Choice, Whelchel Improved, and Rockdale, 

 which produced 39.59, 37.36, 33.92, 32.66, and 32 bu. per acre, respectively. The 

 largest percentage of shelled corn, 8G.9, was produce<l by Roper Gourd Seed, and 

 the smallest, 79.7, by Whelchel Improved. The number of ears required to pro- 

 duce a bushel of shelled corn ranged from 102 for Funk Yellow Dent to 191 for 

 Granberry Choice. 



Seed corn from long ears produced a yield of 24.99 bu. per acre as compai-ed 

 with 26.75 bu. for seed from short ears. The variety used in this test was 

 Marlboro Prolific. 



A comparison of the Williamson, Gilmore, and ordinary methods of raising 

 corn resulted in a yield of 22.87, 29.58, and 34.11 bu. per acre for the 3 methods, 

 respectively. In the opinion of the author an unfavorable season pi-evented the 

 fertilizer applied to the Willi;imson and Gilmore methods from benefiting the 

 crop. 



A fertilizer experiment was conducted to determine the relative values of 

 green cotton seed and cotton-seed meal. All plats received acid phosphate ap- 

 plied at the rate of 150 lbs. and muriate of potash at the rate of 7.28 lbs. In 

 addition to this application cotton-seed meal was given at the rate of ISO lbs. 

 per acre on certain plats and green cotton seed at the rate of 450 lbs. on others. 

 The cotton-seed meal plats yielded at the rate of 31.28 bu. and the cotton seed 

 plats at the rate of 33.54 bu. per acre. These results are taken as indicating 

 that cotton-seed meal is too valuable for feeding purposes to be used as a 

 fertilizer. 



Cotton culture, J. M. Kimbrough {Georgia Sta. Bui. 8-'i, pp. 221-232). — In a 

 variety test the leading varieties and their yields of seed cotton per acre wei*e 

 as follows : Rowden 1,346 lbs., Schley 1,318 lbs., Georgia Best 1,259 lbs., Layton 

 Improved 1,226 Ibs;, Cleveland Big Boll 1.222 lbs., Philip Improved 1,217 lbs., 

 Thornton Russell 1,206 lbs., and Park Russell 1,202 lbs. Schley led in acre 

 yield of lint with 474 lbs., being followed by Layton Improved with 457 lbs. and 

 Philip improved with 450 lbs. The lowest ranking variety, Rehinsen Big Boll, 

 produced only 313 lbs. The number of bolls required to make 1 lb. of seed cotton 

 ranged from 70 in Rowden to 131 in Franklin Improved and Broadwell Double 

 Jointed. This last-mentioned variety was the earliest and the least Productive 

 in the test. It produced 1,107 lbs. of seed cotton per acre, of which 368.68 lbs. 

 was picked August 28, 540.08 lbs. September 10, and 197.52 lbs. October 5. All 

 other varieties gave a fourth picking, which was made October 30. 



In a second variety test the best .yielding sorts were Park Russell, Keenan, 

 Triumph, Schley, Moss Improved, and Sistrunk Prolific. Screened seed yielded 

 at the rate of 1,171 lbs. of seed cotton per acre, as compared with 1,180 lbs. for 

 unscreened seed. 



The results of a comparison of different fertilizer applications indicate that 

 it is advantageous to use home-mixed fertilizers. High-grade guano in this test,
