342 THE KOHL-RAB1 CROP. 



number of plants required per acre will depend, of course, 

 upon the area to be occupied by each, the distances be- 

 tween the rows, and betwqen the plants in the row. This 

 may be readily calculated by the tabular statement given 

 at page 305. In the field a man and a boy will plant 

 4000 to 5000 per day. 



Those, however, to whom this method of growing kohl- 

 rabi does not offer sufficient advantages to induce them to 

 undertake the additional trouble and expense of transplant- 

 ing, may grow the crop successfully by treating it exactly in 

 the same manner as the turnip, the only difference required, 

 being the time at which the kohl-rabi should be sown. 

 This should not be later than the first or second week in 

 April. It may either be sown on the flat or on ridges, 

 as the nature of the soil or the climate may render most 

 advisable (p. 301). The same quantity of seed (from 2 

 Ibs. to 4 Ibs.) is sufficient, and the same drilling machine 

 that is used for the turnips is equally available for this 

 crop. Indeed, many persons who have occasionally tried 

 kohl-rabi, have noticed that the transplanted plants are 

 more apt to depart from their variety than those sown 

 in the field. The general treatment of the growing crop 

 requires the same care and attention as has been recom- 

 mended at p. 303. The hoeing should be commenced as 

 early as possible, and the plants singled out to somewhat 

 wider distances than the turnips, say 15 to 18 inches, 

 the globe varieties requiring more space than those of the 

 oblong form. 



Owing to the early period at which the seed is sown, 

 the young plant has advanced so far in its growth before 

 the "fly" makes its appearance, as to be practically 

 free from any chance of injury from it; while its peculiar 

 aptitude for cultivation in dry soils and dry seasons 

 preserves it from the attack of " mildew," which at a 

 later period of the year inflicts such injuries on our more
