Abstract :

The present study was conducted to evaluate the effect of foliar application of iron and zinc nanochlate treatments including control (foliar application with distilled water), concentrations of iron and zinc nanocholate (0.5, 1, 1.5 and 2 g/l) on morphological characteristics of coriander in 2019-2020 performed in a randomized complete block design with 9 treatments and 3 replications in experimental plots. The results showed that the highest amount of chlorophyll a, total and carotenoids was obtained in the treatment of 2 g/l iron nanoclate and the highest amount of chlorophyll b was obtained in the treatments of 2 g/l iron and zinc nanoclate. The highest leaf area was obtained in the treatment of 2 g/l iron nanoclate with an amount of 3230 cm2. The highest number of umbel was obtained in the treatment of 2 g/l iron nanoclate with 25.33. The highest plant height was obtained in the treatment of 2 g/l zinc nanoclate with a rate of 102.33 cm. The highest 1000-seed weight , highest number of seeds per umbel and the highest number of sub-branches of the plant(with the amount of 11.33) was obtained in the treatments of 2 g/l zinc and iron nanoclate. In general, the results of this study confirm that foliar application of iron and zinc nanoclate treatments had an effect on the growth properties of coriander, so according to the results and considering the positive effect of the studied treatments, it can be Suggested application of iron and zinc nanoclates in coriander nutritional programs.
