Abstract
Water stress is one of the most Environmental factors affecting and limiting plant growth and productivity, mainly in arid and semi-arid regions in the world. This research was undertaken in 2014 to evaluation of changes in leaves and nodes per plant, root/shoot ratio and oil content of coriander (Coriandrum sativum L.) seeds in response to biological and chemical fertilizers, and salicylic acid under different irrigation treatments in Kerman shah province, Iran. The experiment was arranged as split-plot factorial based on randomized complete block (RCB) design with three replications. Treatments were 3 levels of water supply (irrigation after 60, 90 and 120 mm evaporation from class A pan) and 4 levels of fertilization (control, 100 kgha-1 Urea, Nitrokara and biofertilizer, and 50% Urea + Nitrokara) and foliar application of salicylic acid (0 and 1 mM). Increasing irrigation intervals led to significant reduction of leaves and nodes per plant, shoot dry weight, and oil content and yield of coriander seeds. However, root/shoot ratio increased as a result of water deficit. Application of nitrogen fertilizers, particularly 50% Urea and Nitrokara, had a positive and additive effect on number of leaves and nodes per plants, shoot dry weight, root/shoot ratio, and seed oil percentage and yield. On the other hand, plants treated with salicylic acid had higher shoot dry weight and seed oil content and yield compared with untreated plants. Therefore, the combined utilization of bio-fertilizer and salicylic acid can be recommended to improve the oil content and yield of coriander seeds under different water conditions.
