Abstract
In order to evaluate the effect of seed priming and foliar application of lentil plants by Zn and Fe micronutrient, a factorial experiment was conducted based on randomized complete blocks design with 3 replications and 2 factors. The first factor was nutritional priming in six levels [nutritional priming with FeSO4 and ZnSO4 each at two concentrations of 50 and 100 mM, along with no prime (dry seed) and hydroprime as controls) and the second one was foliar spraying with four levels (no foliar spraying, spraying with distilled water, FeSO4 and ZnSO4 at 4‰ concentration). Almost the highest levels of all studied traits were observed in the priming with 50 mM FeSO4 and then ZnSO4. However, by increasing the concentration to 100 mM, there was a reduction in all studied traits in such a way that grain yield decreased by 69.16 and 72.09 percent by 100 mM FeSO4 and ZnSO4, respectively. Also, foliar application of micronutrients increased lentil grain yield by improving yield components, and the highest yields were obtained from a combination of priming with 50 mM FeSO4 and/or ZnSO4 and foliar application of these micronutrients. While priming did not affect the germination traits of the harvested seeds, seeds from plants foliar sprayed with FeSO4 were superior in terms of germination traits and seedling vigour. Overall, the results indicate that the application of micronutrients in the form of priming, foliar spraying, or both can be an effective management strategy to improve crops productions.
