average. On the whole there are not very important differences 



shown by the various systems of pruning plants in this experiment. 



All of the pruned plants, however, ripened more fruit during the first 



seventeen days of harvesting than the normal or unpruned plants. 



Table VIII, showing the results of pruning tomatoes (Lorillard) 



grown in House No. 2. Two rows of vines 4 ft. apart, or 



a total of 26 plants 32 in. apart in the row. Harvested 



May to July. 



The three shoot system in this trial gave a greater average weight 

 of ripe fruit per plant than the two leader system, also a larger 

 average Iveight of fruit per plant. During the first month of harvest- 

 ing the crop 19 per cent more ripe fruit was picked from the two stem 

 plants than from the three stem plants. There was 21 percent more 

 fruit on the three stem plants than on the two stem plants, and the 

 total weight of the former exceeded the latter by 34 per cent. The 

 gain in the average weight of individual fruit was 16 per cent in 

 favor of the three stem system. The following summary table includes 

 the results of the four preceding tables, and from this we are able to 

 obtain some idea of the average results of pruning as applied to the 

 various systems practiced.
