differences in the 3'ields.* The tests which were made the pre- 

 vious winter indicated that the three-stem training gives a 

 smaller yield on the same area of bench than the single-stem 

 training. For this reason the tallest plants were assigned to 

 three-stem training so that there might be no appearance of 

 favoring the single-stem plants in planning the test. For the 

 same reason the tallest three-stem plants were put on the south 

 bench as the previous season's test indicated that the shading 

 of the bench by a purlin made that a less favorable location than 

 the north bench. 



Planting on benches. — October 22 the plants were moved to per- 

 manent places on the side benches of the tomato house and ar- 

 ranged as shown in the accompanying diagram, Plate VIII. 



The plan of the previous season was followed in that no drain- 

 age was put on the bottom of the bench, as it was thought that 

 the perforated tile furnished ample drainage. Five quarts of 

 soil were mounded around each plant. Part of the plants were 

 transplanted to this soil and part were left in the pots in which 

 they were growing and the soil was spread under and mounded 

 over the pot. They will be referred to, the same as on previous 

 pages, as " plants in pots " and '' plants out of pots." 



The plants were set. in two rows, one row ten inches from the 

 front the other ten inches from the back of the bench. The 

 benches are thirty-four inches wide, inside measurement. The 

 plants in the front row alternated with those in the back row so 

 that each plant came opposite the middle of the space between 



*In some instances plants which were the taller at the time of transplanting were 

 more productive and in some cases they were less productive than the shorter plants. 

 The average yields are as follows:

4. Single-stem in pots 6.25- 58.44 



6. Single-stem not in pots 6.25 58.54 



5. Single stem in pots 6.75 53.25 



5. Single-stem not in pots 6.75 61.25 



3. Three-stem in pots 7.25 88.00 



2. Three-stem not in pots 7.25 106.125 



2. Three-stem in pots 7.50 57.50 



3. Three-stem not in pots 7.50 97.83 



The three-stem plants which measured 1V2 inches at the time of transplanting were 

 less productive than the three-stem plants which measured 7V4 inches. This may be 

 partly accounted for by the fact that the former were nearer the west end of the house 

 and during the short days of winter became shaded from the sun earlier in the after- 

 noon than those towards the middle or east end of the house.
