AVERAGE TIME IN A FAVORABLE SEASON 
FOR PLANTS TO MATURE TO EDIBLE CON- 
DITION FROM SOWING OF SEED, WITH 
YIELD PER ACRE FOR IMPORTANT VARI- 
ETIES. 
The earliness of varieties is usually obtained at the 
expense of smallness in size of fruit, head, root, pod or 
grain; in the case of sugar corn, ears of the early kinds 
are not only smaller, but the depth, plumpness and 
sugariness of grain are less than these found in the 
late varieties. 
Artichoke—Matures from 90 to 120 days. 
Asparagus—Cutting season of shoots in spring will 
range from 5 to 6 weeks. From 800 to 1,000 two- 
pound bunches may be cut to an acre; a two-pound 
bunch contains from 10 to 50 stalks, varying according 
to their size.
