Oh yeah. Sorry, I misunderstood your question. Each fruit is worth 1 dollar when selling. So: 10 coconuts > $10, 100 bananas> $100.
However, different fruit plants produce different amounts of fruit per second:
- Coconut: 1
- Pineapple: 2
- Banana: 4
- Watermelon: 8
These base levels are for tier 1 crop fields. If you merge them, or place crops of the same type next to a field, you get multipliers per second.
