Abstract
This experiment was carried out to study the effect of five irrigation levels on growth, yield and chemical composition of coriander plants. The amount of irrigation water was equal to 40%, 60%, 80%, 100% and 120% of the potential evapotranspiration (ETP) values based on class-A pan. The irrigation water was applied by drip irrigation system. The results of this experiment showed that the vegetative growth parameters were improved as a result of applying higher irrigation levels compared to lower levels. Irrigation water use efficiency (IWUE) was increased by reducing the irrigation levels. Increasing the irrigation level from 40% to 120% increased the volatile oil percentage as well as fruit and volatile oil yields/hill and per fed. The results of GC analysis of volatile oil showed that the main components of volatile oil were linalool, ß-cymene, limonene, nerol, borneol and geraniol. However, the irrigation treatments did not affect oil composition. The chemical analysis of the coriander herb indicated that increasing the irrigation rate from 40% to 120% of ETP gradually decreased nitrogen, phosphorus and carbohydrate percentages in the dried herb of coriander plants. However, there was no clear trend for potassium percentage.
