The ''plant harvest yield'' doesn't get applied when harvesting drug plants. For them see ''drug crop harvest yield'' below.

== Summary ==
{{Stub|section=1|reason=Random chance of failure math - is 0.99 a 1% chance of total waste??}}

Yields lower than 100% give a random chance that the entire harvest will be wasted. Yields above 100% will give a proportionate bonus to the amount of resources produced, on average.

=== Offsets ===
The base value of 100% can first be modified by the following offset:

* [[Ideoligion#Plants specialist|Plants specialists]] {{IdeologyIcon}}: {{+|30%}}

=== Factors ===
After the offset is applied, it is further modified by the following factors:

* [[Skills#Plants|Plants]][[Skill::Plants| ]]: ×([[Skill Base Factor::0.60|60%]] + a different amount per skill level). See ''skill table'' below.
* [[Manipulation]]: [[Manipulation Importance::0.3|30%]] importance, [[Manipulation Limit::-|No]] max (effectively {{%|{{Q|Manipulation|Effective Maximum}}|0}})
* [[Sight]]: [[Sight Importance::0.2|20%]] importance, [[Sight Limit::1|100%]] limit
* '''[[AI Storytellers#Economy|Difficulty]]:'''
** Peaceful, Community builder: {{Good|×120%}}
** Adventure story, Strive to survive: '''×100%'''
** Blood and dust: {{Bad|×95%}}
** Loosing is fun: {{Bad|×80%}}
** (custom settings allow between 0% and 500%)

=== Skill table ===
{{Stat Factors Table|l0=0.60|l1=0.70|l2=0.75|l3=0.80|l4=0.85|l5=0.90|l6=0.95|l7=0.975|l8=1.00|l9=1.01|l10=1.02|l11=1.03|l12=1.04|l13=1.05|l14=1.06|l15=1.07|l16=1.08|l17=1.09|l18=1.10|l19=1.12|l20=1.13}}

== Example == 
Plant harvest yield of a particular pawn can be calculated using the following formula:

{| class="wikitable"
|-
| (100% + Offsets) x Skill modifier x (100% + (Manipulation - 100%) x {{%|{{P|Manipulation Importance}}}}) x max({{%|{{P|Sight Limit}}}}, 100% + (Sight - 100%) x {{%|{{P|Sight Importance}}}})
|}

A healthy, Plants 10, Plants specialist with two [[archotech eye]]s would therefore have the following:
* Offsets: 
** Plants specialist: {{+|30%}}
* Skill modifier: {{Good|102%}}
* Manipulation factor:
** 100% + (Manipulation - 100%) x {{%|{{P|Manipulation Importance}}}} = '''x100%'''
* Sight factor:
** max({{%|{{P|Sight Limit}}}}, 100% + (Sight - 100%) x {{%|{{P|Sight Importance}}}}) = 100% + (150% - 100%) * {{%|{{P|Sight Importance}}}} = {{Good|x{{%| 1 + (1.5 - 1) * {{P|Sight Importance}} }} }}

{| class="wikitable"
|-
| (100% + {{Good|30%}}) x {{Good|102%}} x '''100%''' x {{Good|{{%| 1 + (1.5 - 1) * {{P|Sight Importance}} }}}} = {{%|(1 + 0.3) * 1.02 * 1 * (1 + 1 + (1.5 - 1) * {{P|Sight Importance}}) }}
|}

== Drug crop harvest yield ==
{{Quote|"The yield this person gets when harvesting drug crops.<br/>Low yields give a chance that this person will accidentally waste the harvest. High yields increase the yield from each plant."|Drug crop harvest yield description}}

The ''drug crop harvest yield'' is the stat that gets applies when harvesting [[ambrosia bush]]es, [[hop plant]]s, [[smokeleaf plant]]s, and [[psychoid plant]]s. Its minimum allowed value is 0%. Its maximum allowed value is 150%. Its default value is 100%. It is modified by the following two factors:

* ''Plant harvest yield'': ×0% to ×150%. See above. 
* [[Ideoligion#Drug_use|Drug use: Essential]] {{IdeologyIcon}}: {{Good|×150%}}

== Version history ==
* [[Version/0.12.906|0.12.906]] - Unskilled or injured growers can fail at harvesting, destroying the harvest for one plant
* [[Version/1.3.3066|1.3.3066]] - PlantHarvestYield stat above 100% gives a bonus to yield.
* [[Version/1.4.3523|1.4.3523]] - Fix: High Life harvest yield for Drug Use: Essential precept doesn't work.
