188 VEGETABLE GROWING PROJECTS 



1. When should the different root crops be planted ? 



2. What is the relation of varieties to the time of planting ? 



7. Spacing the rows. 



When the root crops are to be culti- 

 vated with a hand 

 wheel hoe, they are 

 usually fourteen 

 inches apart. Many 

 growers prefer some- 

 what more space for 

 the parsnip, carrot, 

 and late beets. 

 Radish rows may be 

 closer together than 

 any of the other root 

 crops. An increasing 

 number of gardeners 

 prefer to allow about 

 two feet between rows 

 and then cultivate the 

 crops with a horse. 

 While the wider plant- 

 ing decreases the yield 

 per acre it also re- 

 duces the labor bill and makes possible a larger area under culti- 

 vation with the labor available than when the work is done 

 with hand wheel hoes. 



1. How far apart should the rows of the different root crops be 

 for wheel hoe tillage? For horse tillage? Which will pay 

 you the best ?
