THINNING

Fig. 104. — Results of thinning onions. The onions in the box at the left were thinned 

 so that the plants stood three inches apart in the row; those in the box at the right were 

 not thinned. 



Fig. 105. — Good and poor onions shortly before the harvest. The tops of the good 

 onions have fallen over due to the shriveling of the necks; the poor onions, with thick necks, 

 still stand erect.
