19181 FIELD CROPS. 437 



A test of varieties propagated from home-grown seed stored in an ordinary 

 farm cellar during 1916 and 1917 at Fayettevllle resulted in average yields for 

 tlie leading varieties of 83.8, 82.29, and 80.47 bu. of marketable tubers per acre 

 for Rural New Yorker No. 2, American Wonder, and Prosperity, respectively. 

 The average loss from decay of these varieties amounted to 53, 42, and 5 per 

 cent, respectively, and varied from 1..5 per cent for Manistee and Norcross to 

 76 per cent for Quick Crop for all the varieties tested. Bliss Triumph sus- 

 tained a loss of 25 per cent. Digging dates found most satisfactory for suc- 

 cessful storage were from July 1 to 15 in the Ozark region and from June 1 

 to 10 in the Arkansas River region. 



Seed potatoes from the first crop to be used for fall planting were stored 

 in the ground, in sand and nmlch, and dry straw mulch, and in cellar, shed, 

 and deep pit at Fayettevllle, and in the ground, shed, and cellar at Van Buren. 

 A cooperative test in refrigeration was conducted at Eldorado. Ground stor- 

 age resulted in considerable loss of seed from decay, while practically no loss 

 was sustained from the other methods. The stand of plants from seed stored 

 in sand and mulch, and in the ground at Fayettevllle was 33 per cent greater 

 than that from seed stored in other ways, and at Van Buren 50 per cent 

 greater for seed stored in tlie ground.

 Arkansas, and recomeuds varieties adapted to conditions in the State. 



Sugar-cane experiments in the Leeward Islands, 1915—16, H. A. Tempany 

 ET AL. {Imp. Dept. Ayr. West Indies, Sugar-Cane, Expts. Leeward Isl., 1915-16, 

 pts. 1-2, pp. 76, pi. 1). — Variety and fertilizer trials with sugar cane conducted 

 in Antigua, St. Kitts, and Nevis in 1915-16 are reported as in previous years 

 (E. S. R., 35, p. 443). 



In the variety tests at Antigua, the five leading plant canes and their yields 

 per acre were as follows : B. 6308, 32 tons of cane and 5,600 lbs of sucro.se ; 

 B. 4590. 32.2 tons of cane and 5,160 lbs. of sucrose ; B. 1528, 27.8 tons of cane 

 and 4,730 lbs. of sucrose; B. 6388, 25.8 tons of cane and 4,710 lbs. of sucrose; 

 and B. 3922, 25.4 tons of cane and 4.540 lbs. of sucrose. The lowest yield was 

 secured from B. 1753 with 15.2 tons of cane and 2,020 lbs. of sucrose. Of 13 

 varieties which have been under experimental cultivation for the past 15 

 years, Sealy Seedling has given the highest mean yield of sucrose, 6,4.50 lbs* 

 per acre, with B. 208 second with 6,270 lbs., and B. 156 third with 6,150 lbs. 

 The highest yield with ratoon canes for the year was obtained from B. 374T 

 with 28.5 tons of cane and 4,630 lbs. of sucrose, with B. 3922 second with 26.9 

 tons of cane and 4,500 lbs. of sucrose. Sealy Seedling, with an average yield 

 of 3,680 lbs. of sucro.se per acre, was first of 12 varieties of ratoon canes tested 

 for the past 15 years, and B. 156 second with 3,560 lbs. The lowest yield with 

 ratoon canes for the 1915-16 season was from A. 5, 14.3 tons of cane and 2,040 

 lbs. of sucrose. 



At St. Kitts the five leading plant cane varieties were D. 109 with 36.3 tons 

 of cane and 8,090 lbs. of sucrose, D. 216 with 36.6 tons of cane and 7,930 lbs. 

 of sucrose, B. 4596 with 39 tons of cane and 7,670 lbs. of sucrose, B. 254 with 

 33.2 tons of cane and 7,620 lbs. of sucrose, and White Transparent with 33.1 

 tons of cane and 7,540 lbs. of sucrose. The lowest yield was secured from 

 B. 1753 with 20.4 tons of cane and 3,870 lbs. of sucrose. The highest average 

 yield for all seasons was secured from D. 216, 7,930 lbs. of sucrose for one 

 season, with B. 208 second -with an average of 7,620 lbs. of sucrose for 16 

 seasons, and D. 109 third with 7,400 lbs. of sucrose for 11 seasons. In tests 

 with ratoon canes for 1915-16, A. 2 was first with 35 tons of cane and 7,660
