Abstract


Chickpea (Cicer arietinum L.) is the third most extensively planted grain legume in the world after dry bean and field pea. Priming in is a pre-sowing seed invigoration technique in which the seeds are pre-soaked before planting. Micronutrient seed priming include seed priming with nutrients solutions and sowing seeds enriched in micronutrients can be agronomically beneficial. Current study carried out to evaluate seed pre-sowing treatment in the different solution of nano oxide iron and zinc (0, 5, 10, 15 and 20 mg) on germination and seedling growth of Kabuli chickpea under laboratory condition. Results revealed that seed soaking in distilled water significantly improved the germination percentage and rate in comparison with intact seeds. The longest and the heaviest seedlings were recorded for seed soaked in 5 mg nano-iron solution which followed by 15 mg nano-iron. The positive effects of seed priming in nano-zinc solution were not considerable and prominent when compared with nano-iron solution. Overall, the results showed that high concentrations of nano-scaled micronutrient can be toxic for seedling growth and this status was more evident for iron oxide nano-particles. Seed priming with diluted solution of nano-iron was more efficient for improving seeding growth.
