Pruning for Increased Yield — Result of 



Summer vs. Winter-Pruning 



Experiments. 



During the four-year period there 

 was an increase in favor of the sum- 

 nier-pruncfl Wagener of 111%, varying 

 Ihroughout the four years from 83.6% 

 increase to 227.8% increase. 



The Grimes showed, during a four- 

 year period an increase of .52.8% in 

 favor of the summer-pruned trees. 

 The per cent of increase varied from 

 19.7% in 1911 to 86.8% in 1913. 



Paddoclv ..^ Whipple, in their book 

 entitled, "Fruit Growing in Arid Re- 

 gions," say that summer pruning is 

 supposed to incite fruitfulness, but 

 does not always give uniform and sat- 

 isfactory results. While our .lonathans 

 show an increase of 2.4% during the 

 four-year period in favor of the sum- 

 mer-pruned trees, the per cent during 

 the period varies from 13.8% increase 

 to 66.7% decrease. 



There has been but very little differ- 

 ence between summer and winter prun- 

 ing of the Rome during the four-year 

 period. An increase of 1.6% is noticed 

 in favor of the summer-pruned trees.
