15. Staking Tomatoes. — Stake one row of tomato plants 

 ajid tie the plants up well. Let the plants of the next row 

 grow without staking. Determine which ripen first, which 

 rot worse, and which are harder to pick. If possible, calculate 

 the cost of staking and tying. Compare the extra cost with 

 the increased returns from the crop (Fig. 74).

16. Thick or Thin Plantings. — Plant one section of a row 

 very thick, say with lettuce or beets, then another part may be 

 planted rather too thinly, and another part of medium thick- 

 ness. Study the effects of crowding in the first section ; note 

 the extra growth of weeds where the plants are too thin. 



The trial may be varied by planting all the row alike and 

 then thinning the plants after they are up, to study the 

 benefits of thinning.
