Abstract :
To study the effects of water stress and animal manure on nutrients concentration, essential oil percentage and its chemical components in Cuminum cyminum, an experiment was conducted at the Agricultural Research Station of Zahak, Zabol, during 2003–2004 in a randomized complete block design arranged in factorial with four replicates. Treatments were there irrigation (I1: two times irrigation, I2: three times irrigation and I3: four times irrigation) and two animal manure levels (F1: no manure and F2: 20 ton/ha manure). The chemical composition of the essential oil was examined by gas- chromatography (GC) and GC-MS. The effect of water stress on Na, Ca, Mg, Fe, P and K percentages was significant but its effect on Mn, Zn and Cu was not significant. I1F1 had maximum of Na, Ca, Mg and minimum of micro nutrients. Using of animal manure was not effected on nutrients. The effect of water stress and animal manure were significant on essential oil and its chemical compositions. I2F2 had the highest of cuminaldehyde and ρ-cymene and the lowest of β-pinene, γ-terpinene and α-pinene. Result showed that there is a correlation among the main components of cumin essential oil under water and mineral stress.
