Abstract
Salicylic acid (SA) is known as an antioxidant compound involving in plant tolerance to various biotic and abiotic stresses, thus this trial was conducted to study the effects of SA application and irrigation intervals on yield and yield components of coriander using a split-plot layout in a randomized complete block design with three replications. Two levels of irrigation including irrigation every 4th day & irrigation every 8th day were compared in main plots. Four levels of salicylic acid (SA) including: 0, 0.01, 0.1 and 1 mM of SA were assigned in sub-plots. Results showed that the reduction of irrigation interval from 8 to 4 days statistically improved umbels number per plant, seeds number per plant and seed yield. Application of lower doses of SA increased the number of umbels and seeds per plant and seed yield. Evaluation of interaction effects of irrigation and SA revealed that in optimal conditions of water availability the crop was more responsive to the lowest dose of SA, on the other hand in water deficit conditions the median dose of SA (0.1 mM) was more efficient in improving seed yield, indicating the positive and enhancing role of SA under water deficiency stress conditions.
