Nitra Tree Seed

 is a seed that can be planted in a Large Planter Box to grow Nitre.

Obtaining
can be purchased at the following shop:

One can also be found in a treasure chest behind a rock in the western Eufaula Desert.

Usage
can be planted in a Large Planter Box in any season to grow a Nitra Tree to produce Nitre. The tree grows in two stages: a growth stage of 15 days (time a sapling needs to reach maturity) and a harvest stage of 8 days (time a mature tree needs to bear fruit).

The tree persists after the crop is harvested and will continue to produce Nitre every 8 days, but can be uprooted if the player wishes. The tree will also be lost if the player picks up the planter box and puts it into their inventory or if the player sucks the planter box into their inventory with a Vacuum Cleaner.

The base Nitra Tree yield is 29-30 Nitre. The player can harvest 58-60 Nitre if they keep the tree fully fertilized during its whole growth and harvest stages; if the tree was not fertilized during its growth stage it will not produce the double harvest.
