3. What should be the character of the cultivation ? 

 W-VG:394. C:315. 



11. Weeding. — W : 307. Though the most perfect cultivation 

 may be given onions, some hand weeding is nearly always required 

 to destroy weeds in the rows. Various types of small hand weeders 

 are in common use. It is important to keep the plantations 

 entirely free from weeds. 



1. What hand tools will you select to weed your onions? Give 

 reasons for selecting them. W-VG : 394. L : 166. 



12. Thinning. — W : 308. It is customary to remove some of 

 the plants at the time of weeding, if they are too close together. 

 As stated in W : 238, most growers want from eight to twelve plants 

 to the foot of row. If the soil is very fertile and large bulbs are 

 wanted, a minimum number of plants should be left. 



1. What will be your policy in the number of plants left per foot of 

 row? 



13. Irrigating. — W : 235. The onion responds to the most 

 perfect cultural conditions. Some growers are so anxious that 

 there be no unfavorable conditions at any period of growth that 

 they install overhead irrigating or sprinkling devices so that 

 artificial rain may be produced at will. There are times when a 

 thorough watering is urgently important, and fortunate is the 

 grower who is prepared to supply all the water that the crop may 



' need and at the time it is needed. 



1. Would it pay you to install an irrigating system for this and other 

 crops that you intend to grow? 



14. Combating insects and diseases. — W-VG : 405. Owing 

 largely to cultural methods, onion insects are difficult to handle.
