Abstract
This study investigated the effect of organic fertilizers on vegetative
growth and the physiological and antioxidant activity characteristics of thyme
plants grown under stress. A factorial experiment was conducted according to
randomized complete block design with 12 combinations and 3 replications in
the 2018 growing season. The experiment factors were the implementation of
organic fertilizers at 4 levels (vermicompost, manure compost, animal manure,
and control) and irrigation regime at 3 levels (Irr1, Irr2, and Irr3, respectively,
irrigation after 60, 90, and 120 mm evaporation from A pan). The results showed
that With delayed irrigation, the chlorophyll a and b contents, total chlorophyll,
and carotenoid decreased, while the application of low water stress enhanced the
amount of oil and the oil yield with the respective highest values of 2.61% and
3.68 g/m under mild stress conditions. Nonetheless, higher values for the
aforementioned properties were noted with the application of vermicompost.
Water deficit decreased nutrient uptake (K, P, and N) and relative water content,
biological yield, and seed yield of thyme, indicating that thyme was sensitive to
drought, and organic fertilizers application improved nutrient uptake (K, P, and
N) and relative water content, biological yield and seed yield of the plant within
irrigation levels. The activities of catalase, superoxide dismutase and ascorbate
peroxidase were reduced under organic fertilizers such as vermicompost and
manure compost as compared with control under drought stress. The plants of
thyme showed a good response to organic fertilizers under water deficit
circumstances, with vermicompost being the most effective.
