COLE CROP PROJECTS 103 



lettuce may be set between two rows of cabbage and, if the spacing 

 is ample, radishes may be sown between rows and even between 

 plants in the rows. The radishes mature and are harVested first, 

 then the lettuce grown from transplanted plants, and finally all 

 of the ground is devoted to the cabbage crop. It is unlikely that 

 these crops seriously interfere with each other, though they make 

 tillage more tedious, but they greatly increase the producing 

 power of the area under cultivation. The cabbage may be har- 

 vested in time to follow with a crop of beans or perhaps a green 

 manurial crop, such as ^'etch or crimson clover, that may be plowed 

 down the following spring for tomatoes and other vegetables. 



1. Describe several sysfrms of comhination cropping ivhich include 

 cabbage. W-VG : 477-478, 480, 486, 488. 



17. Cultivating. • — • Both the early and the late crop should have 

 frequent and thorough tillage. When the plants are well grown, 

 fewer leaves will be broken off if the cultivating is done in the 

 middle of the day when the leaves are limp or less rigid than in the 

 morning or evening. 



1. See W : 99 and references. 



2. What recommendations do you make for the cultivation of 



cabbage? W-VG : 273. 



18. Combating insects and diseases. — Among the cruciferous 

 plants, cabbage and cauliflower are probably more seriously in- 

 jured than other cole crops by species of insects common to the 

 entire group. Attacks by the insects are usually coincident with 

 the appearance of the first leaves in the seed bed and continue 

 throughout the growing season. 



The wilting of early cabbage plants in the field or late plants 

 in seed beds is a good indication of an attack by root maggot.
