Sugar beet growing, J. Wilson, C. F. Curtiss, B. S. A., D. 



A. Kent. B. S., and G. E. Batkick, M. S. (pp. 100-LM ».-)).— In ISMl 

 sugar beets were grown at the station on '' comparatively new" hinni 

 soils, both with and without fertilizers and with subsoiling. Lime, a 

 "complete fertilizer," and ammoniatcd su|>erp!i(>s[iliate were used in 

 amounts not stated. Beets were planted at dill'crent dates from April 

 1.") to May L'.j. The varieties treated were Klein Wanzleben, ^'ilmorin, 

 and Dcsprez. Samples of the beets were taken for analysis Sei>tember 

 30, October IL*. and November 6. The yield and composition of the 

 beets are tabulat«'d. Beets were produced with as high as 15.7 percent 

 of sugar, giving juice of 8l'.5 purity, and 5 samples contained over 1-i 

 per cent of sugar. 



(1) Early i»lantiu{j <?ave the {greatest tonnaye and most sugar per aero. 



(2) Very large lieets did not sugar well. 



(3) Sultsoiling gave the l)e8t sliaped beets and the higliest per cent of sugar in 

 Novenilter, needing the least triuiniing. 



(4) Cutworms destroyed most of the early idautiiigs, hnt did not allect tlie latir 

 plantings. 



(.">) Per eeiit of sugar w:is atteeted by second growth in October or l>y alisorbing 

 moisture frf>m rains after long drouth, or both. 



(»») Yield i>er acre has much to do with the ]>rotitableness of tiie crop. 



(7) Wliile our liighest analysis <ame from beets a\eraging 13 ounces trinuned and 

 yielding l'2.',i'2 tons per acre, our l.irgest yield of sugar per acre came from beets aver- 

 aging '_'! oun<'es trimmed and yielding 'JS.lt! tons per acre. 



(5) Clay soil g.ive us the liighest per centof sugaraudcoinparati\el,\ higlicr purit \ , 

 and the lowest tonnage jter acre. 



(!•) The plats fertilized with lime, nitrogen, plmspliorie aii«l. and potash showed no 

 benefit. 



(10) The aver.'ige per cent of sugar was 11.11 and the average _\ielil about 20 tons 

 per acre, and the cost of growing and harvesting $oH. lU i)er acre. Tlie highest sngar 

 in beets per acre was 7,'_'5>tl jHuinils. 



Sugar iieets in Iowa, 18U1, (l. E. Patrick, ,^I. S., E. N. Eaton, 



B. S., AND I). B. JiiSBEE, B. S. dtp. LMKi-2;i3).— This is a rei»ort on the 

 analysis of ~jO- samples of sugar beets grown in 4!) counties of the State. 



The proposition made in Ibilletin No. 12 of the statitui [see Kxperinient Station 

 Ive<'ord. vol. II, p. 718J for an extj-nsive invest ig.ition of thi- possibiiitiis of sugar 

 beet culture in this State, to be made jointly by the farmers of the State and tin 

 chemical section of the station, has ri'sulted in the work re|n>ite<l in this arlicb-. 



The results here recorded are aliimst wlndly tli<ise obtained in the laboratory. Tlie 

 information furnished by tlie growers regarding the character of the soil in \vhi( b 

 the beets were grown and its treatment before planting an<l during growth of the 

 crop, must bo brought into condensed form before it can be of much value to the 

 public, and as it will take considerable time to do this that portion of our report is 

 reserved for a future bulletin. • • »
