the number of tomatoes she picks each week

the number of tomatoes she picks each week

the amount of fertilizer she puts down each week

Answer 1

the height of each tomato plant

Answer 2

The question in the beginning sentence is "to see if a kind of fertilizer helps her tomato plants produce more tomato fruits". So it seems to me that she doesn't care how high the tomato plants get, the question is how many tomato fruits are produced.
