Corn

Unlocks once you've harvested 38 Wheat, 30 Cabbage, 16 Carrot and 8 Celery in all; unlocking it is then free.

A seed costs 5 spare parts and grows for 3m 50s (3m 4s on fertilized soil), needing water 5 times on the way: it stops growing until it's watered. It gives 5 harvests, growing back from scratch after each one.

Each harvest is one Corn and 4 spare parts: 20 from one seed, 15 more than it cost, over 19m 9s of growing. In a Biofuel Converter each one is worth 4 biofuel.

A Reaper chip can improve its grow time, watering, harvests, biofuel or earnings.
