The yields of different varieties of sugar l)eets are here reported, Init the chemical 

 analyses of the corresponding samples have been given elsewhere (see E. 8. R. , 15, 

 p. 1072). Of 19 varieties grown for 4 years, 11 gave an average yield of over 20 tons 

 per acre. In a 10-years' test with 8 varieties, Red Top, Lane Improved, and White 

 Silesian headed the list with average yields of 19.8, 19.5, and 19.5 tons, respectively. 

 Kleinwanzlebener gave an average yield of 18.81 tons per acre for 4 years. In 4 

 tests during 2 years, drills 18 and 20 in. apart produced an average of about 2 tons 

 per acre more than drills 28 in. apart. Thinning experiments made in duplicate in 

 19011 with the Kleinwanzlebener variety showed that an increase in the average size 

 of the root, together with a gradual decrease in the yield, took place as the distance 

 between plants in the row increased from 2 to 10 in. Planting sugar l)eets on the 

 level gave over a ton of beets more per acre than planting on ridged land. Four tests 

 made in each of 5 years with selected beet seed resulted in the following average 

 yields: Large seed balls, 22.9 tons; medium-sized seed Ijalls, 21.9 tons; small-sized 

 seed balls, 14.3 tons. In 2 tests made this season an average of 15.8 tons per acre 

 was obtained from seed soaked 12 hours, as compared with 13.9 tons from unsoaked 

 seed. 



The largest yields of sound potatoes per acre in 1903 were as follows: Empire State, 

 336.7 1)u.; Pearl of Savoy, 325.4 bu.; Seedling No. 230, .322.1 bu.; Up-to-date, 315 

 bu.; Salzer Earliest, 312.9 bu.; American Wonder, 312.1 bu.; White Elephant, 309.1 

 bu. ; Dempsey Seedling, 306.3 bu.; New Main Crop, 288.8 bu., and Howe Premium, 

 281.7 bu. The percentage of rotten potatoes of each variety for the season is also 

 given. Of different varieties tested for 10 successive years, Empire State, Pearl of 

 Savoy, Rose New Invincible, Rural New Yorker No. 2, American Wonder, and 

 White Elephant have been among the best yielders. This season the following sorts 

 produced the largest average yields 9 weeks after planting: Acme, 233 bu.; Early 

 Dominion, 215 bu.; p]arly Andes, 214 bu., and Early Ohio, 210 bu. per acre. The 

 average yields in this test for 8 years were as follows: Stray Beauty, 107 bu. ; Early 

 Ohio, 105 bu. ; Early Dominion, 101 )>u. ; Howe Premium, 99 bu., and Burpee Extra 

 Early, 79 bu. The results and cost of different methods of treatment for the potato 

 beetle, as determined by experiments, are given. Bordeaux mixture, applied in 

 combination with Paris green, reduced the rot. 



Thirty-three varieties of mangels were under test this season. Yellow Leviathan 

 and Sutton Mammoth Long Red, yielding 43.1 and 42.4 tons per acre, respectively, 

 headed the list in productiveness. All other varieties yielded under 40 tons per acre. 

 Among 15 varieties tested for 6 years in succession Yellow Leviathan, Sutton Mam- 

 moth Long Red, 01)long Giant Yellow, Mammoth Golden Giant, and Steele-Briggs 

 Giant Yellow Intermediate ranked first, the yields being 33.5, 33.2, 32.6, 32.2, and 

 31.8 tons, respectively. In a comparison of unsoaked seed and seed soaked 12, 24, 

 and 36 hours, the average yield for 2 years was in favor of the seed soaked 12 hours. 

 The average results for 5 years show that the yield of mangels decreased as the dejith 

 of planting increased from ^ to 4 in. Better yields were obtained from unbroken seed 

 balls of mangels and sugar beets than from those broken or crushed. On a series of 

 plats the first crops of common red clover, alsike clover, and timothy were i)lowed 

 under and the land then planted to mangels. The average results of the season show 

 that the common red cltjver land yielded 2.1 tons and the alsike clover land 3.6 tons 

 per acre more than the timothy land. The average results for several years in com- 

 paring varieties of swedes, fall turnips, carrots, and parsnips, were in favor of Sutton 

 Magnum Bonum, Red Top White Globe, Mammoth Intermediate Smooth White, and 

 Improved Half Long, respectively, the yields being 21.5, 27.5, 31.3, and 11.8 tons 

 per acre, in the order indicated. Planting carrot seed i and 1 in. deep gave the same 

 average results for 10 different tests, while planting at greater depths reduced the 

 yield considerably.
