Describing land or crops that do not receive water through artificial means such as irrigation.
The unirrigated fields struggled to produce enough crops during the dry season.
Unirrigated → It is formed from "un-" (meaning not) and "irrigated" (from Latin "irrigare", meaning to water). The word "unirrigated" means not watered or lacking irrigation.
Think of 'not' ('un-') having water ('irrigated') — that's why unirrigated means not watered.
