their shape into lon^ red, ovoid, and globe varieties. The percentages 

 of sugar in dirt'ereut varieties grown at distances of 20 and 33 inches 

 apart are tabulated. The sugar content was low in both cases, rang- 

 ing from 5 to 8 per cent. In 1890 it cost $37 per acre to raise the sugar 

 beets and in 1891 $15. 



The nature and results of the experiments reported are shown in the 

 following summary: 



(1) While uewseed is not au absolute necessity to insure a crop of mangel-Avurzels, 

 it is better to use new seed if it can be had. Testing uiangel-wurzel or sugar beet 

 seed before phinting is considered indispensable. 



(2) In each class orvariety of mangel-wurzels are found several strains, and while 

 these do not dilier materially, some have qualities that make them more desirable 

 than others. In the long red class, the Giant Long Red has in a series of years 

 seemed to have more vitality in the seed used, and has given a more satisfiictory 

 average growth than any other one of that class. The Giant Holstein, Dignity, and 

 Jumbo have all made occasional higher yields than the Giant Long Red, and are 

 among the best sorts in that class. The Giant Yellow Intermediate, Yellow Ovoid, 

 and Yellow Leviathan are among the better kinds in the ovoid class. The globe 

 class as a whole has been the least valuable type of mangel-wurzels. 



(3) According to the experiments detailed in this bulletin, an acre of sugar beets, 

 properly grown, is decidedly more valuable for feeding stock than an acre of mangel- 

 wurzels. 



(4) The sugar beets grown at this station during the past year have shown a per- 

 centage of sugar too small to justify growing them for sugar-making purposes. 



(5) Transplanting mangel-wurzels has not been attended with satisfactory results, 

 except in filling up rows to make a more perfect stand. Cutting off the leaves when 

 transplanting has not been any benefit. 



(6) Manuring land with fresh barnyard manure has been detrimental to the grow- 

 ing of mangel-wurzels and has in every case decreased the yield. Continuous crop- 

 ))ing with mangel-wurzels has resulted in reducing the ability of the land to produce 

 this crop by at least 10 per cent each year for the first 3 j-ears. 



(7) Preserving the leaves of mangel-wurzels and beets in the silo with corn silage 

 lias not been found practicable. It has been found possil)]e to preserve them in a 

 well or cistern in the ground with but little loss, but they were not relished by the 

 stock, even when well kept. On account of the large proportion of fertilizing elements 

 in the leaves it is advisable to leave them upon the ground.

Field experiments with coMMEnniAL fertilizers, C. E. 

 TnoRNE AND J. F. Hickman, M. S. A. (pp. 35-57). — Experiments 

 on corn (pp. 35-52). — Experiments were made at the station on 22 

 tenth-acre i^lats which had been used for a similar purpose for 3 pre- 

 vious years. The treatment of these plats was similar to that described 

 in Bulletin vol. iii, No. 2 of the station (see Experiment Station Record, 

 vol. II, p. 122). The yield of corn and stover, the increased yield with 

 fertilizers, and the yields of the same plats in the 3 previous years are 

 fully tabulated. The average yield of the unfertilized plats in 1891, 

 which had received no fertilizers for 4 years, was 57.3 bushels per acre. 

 The cost of the fertilizers is based on the retail prices in Baltimore 

 January, 1892, adding f§5 per ton for freight.
