apart and pruned to two stems were third in yield and the highest in 

 the amount of rot."' 



S. A. licach' found the single stem training superior to the three 

 stem training for forcing of tomatoes in this climate in greenhouses, 

 both in the amount of fruit ri[XMiing earlier in the season and in the 

 yield for equal areas. He found, however, slight differences in the 

 average size of fruit produced, but on the whole the fruit on the single 

 stem plants seemed to average slightly larger than on the three stem 

 plants. 



E. J. Kyle and K. C Green" state that the single stem method has 

 proven most profitable from the fact that its use produces the earliest 

 ripenings besides causing a uniformity in size that cannot be other- 

 wise obtained. They recommend that when three well formed clus- 

 ters have established themselves to pinch all others that form as well 

 as the terminal bud itself. 



L. H. Bailey' found in outdoor culture that single stem tomatoes 

 gave twice as much yield per scpurre foot of ground surface as ordi- 

 nary culture, together with somewhat earlier results and greatly 

 decreased injury from rots. He recommends for greenhouse culture 

 the single stem with the leader pinched back. He also recommends 

 cutting off the lower leaves when they commence to deteriorate or 

 interfere in any way with the development of the fruit. 



F. S. Earle^ regards pruning to the one shoot system as being 

 practicable for outdoor crops of tomatoes in the south. From his 

 experiments he obtained decidedly heavier and earlier pickings on 

 pruned plants than on un pruned ones, the av^erage weight of the 

 fruit being from 5 to 15 per cent greater. 



( )n the other hand, J. F. C. DuPre' maintains that while pruning 

 and training may be practicable on a small scale it is not on a large 

 scale when outdoor culture is practiced. 



It would appear from these experiments covering a wide range of 

 conditions that the general consensus of opinion is in favor of prun- 

 ing, that it promotes maturity and larger sized fruit. The single stem 

 plants are also superior to the others giving a larger yield per square 

 foot of o^round surface.
