 cultivation during the early period of growth. Frequent 

 cultivation in the early growing season is important, as 

 at this time an abundant moisture supply is desirable for 

 the beets. 



339. Harvesting. — The harvesting may be divided 

 into four operations, namely, lifting, pulling, topping,
