FIELD CROPS. 39 



At the Buncombe farm, corn yields ranj^ed from 13.1 to 28 bu. per acre, 

 r.oone County White and Tliompson I'rolitic produced the best yields on upUxnd 

 soil. The I'atton variety produced the poorest yield on this soil and the best 

 yield on the bottom soil. 



Tests of varieties of cotton in 1909, J. F. Duggar and E. F. Cauthkn 

 (Alabama Co!. Sta. Bui. l.'i'J, pp. 3-S). — Crimson clover sowed on inoculated land 

 September 9 between corn rows produced a crop 10 to IS in. high by the following 

 April, which when plowetl under enabled the thin gray, sandy land to produce 

 unusually large yields of cotton. In a variety test of 30 varieties. Cook No. 200, 

 Cook No. 221. Dixie, and Hardin produced the most profitable yields as corrected 

 to uniform stand. Prevalence of anthracnose on the station farm afforded 

 opportunity to test the relative susceiitibility of varieties to this disease. The 

 Kowden, Cleveland. Dixie, and Simpkins varieties showed only 5 per cent each 

 of diseased bolls. 



Cotton, 1909, W. 11. Perkins {MlssissiiJiJi Sta. Bid. 135, pp. 16). — Meteoro- 

 logical data for 1909 are presented, together with variety, fertilizer, and cultural 

 tests, and notes on cotton breeding and preparation of the soil. 



In a test of 23 varieties the maximum yield, 2.310 lbs. of seed cotton per acre, 

 was produced by Cook Improved, which was also one of the most diseased 

 varieties, while the least diseased were Sugar Loaf and Gold Coin, which stood 

 sixth and fourteenth respectively in yield per acre. Plantings of cotton in rows, 

 4, 5, and ft. apart produced yields of 2,175, 2,049, and 1,930 lbs. of seed cotton 

 per acre respectivelJ^ Topped cotton excelled in yield that which was not 

 topped and had an advantage in early maturity. In a 3 years' fertilizer test, 

 the maximum average yield of 2,176 lbs. of seed cotton per acre was produced 

 on the plat fertilized at the rate of 2.000 lbs. of manure per acre, while that 

 fertilized at the rate of i ton of manure and 100 lbs. of lime per acre produced 

 1,890.4 lbs. Each of the 11 formulas was tested in duplicate to ascertain the 

 effect of a light application of nitrate of soda at time of planting, but no beuetit 

 appeared from the application. 



The average period required for the maturity of bolls from blossoms that 

 were white on July 15 was 46 days, from those white on August 2, 45 days, and 

 from those white on July 24, 44f days. The tendency appeared to be for the 

 smaller boiled varieties to open in a shorter period than that required by the big- 

 bulled varieties. No marked difference in earliuess of maturity appeared to fol- 

 l<iw plowing at different depths or different applications of fertilizer. 



American cotton system, T. S. Miller, Sr. (Austin, Texas, pp. VII-{-29.'i, 

 pis. .?. — A chapter on the history and botany of cotton is followed by discussions 

 of the classification and marketing of the tiber, the origin and operation of cotton 

 exchanges, and the aritlinietic of cotton. 



Effect of future contracts on prices of cotton. — Influence of producers' 

 organizations on prices of cotton (U. S. Dcpt. Com. and Labor, Itpt. Comr. 

 ('(jiporalioiis on Cotton J-J.rclunit/cs. I'JO!), pts. .) and 5, pp. XXII-\-370, cttarts 

 .i-'f)- — Future prices, abnormal discounts, hedging, fixed differences, spot prices, 

 short selling, and producers' organizations and their eft'ects upon prices of 

 cotton are fully treated by statistical and grajthic methods. The Farmers' 

 Union, the Southern Cotton Association, and the National Cotton Association, 

 and their purposes, forms of organization, membership, and methods of oper- 

 ation are treated, as well as their efforts to reduce acreage and to maintain the 

 price of cotton by action with respect to mininuim prices and warehouse policies.
